2.1. On the Site
a. The Customer will click on a link or type in the address of the Site.
b. The Customer will follow the instructions of the Site and in particular, the instructions necessary for the registration of the Customer, reflected by the creation of a User account if he does not already have one: in this case, the Customer will have, in particular, to provide information relating to his title, his name, his first name, his billing address, e-mail address and phone number. The Customer agrees to provide true and accurate information. The Customer may, at any time, modify his personal information, his login and password, by accessing his account.

In the event of a possible loss of the password, when opening the session and entering the username and password, the Customer can click on a link that will allow him to ask the Publisher to grant him a new password that will be sent to the address indicated in his personal information.
c. From then on, the Customer will read the present on the link "Subscription Terms & Conditions" as well as the conditions of access and use of the site and the applications. The Customer will then check the box "I accept the Subscription Terms & Conditions and Conditions of access & use".
d. It is then up to the Customer who wishes to access the Paid Services to fill in the order form. In the event of prolonged inactivity during the connection, it is possible that the selection of the Paid Services chosen by the Customer before this inactivity is no longer guaranteed. The Customer is then invited to restart the selection of the Paid Services from the beginning. The Customer will check the elements of the order and, if necessary, identify and correct any errors; it is always possible to abandon the order until confirmation.
e. The Customer will confirm the order and follow the instructions of the Payment Service Provider to pay the Total Price.

The Customer may, at any time, modify his personal information, his login and password, by accessing his account.

c. In any case, the subscription to the Paid Services is made with the platform. Therefore, in addition to reading these terms and conditions on the "Subscription Terms" link, as well as the terms and conditions of access and use of the website and applications, and checking the box "I accept the Subscription Terms & Conditions and Conditions of access & use", the Customer will also be bound by the general terms and conditions of the Apple Store, Android platforms or Payment Service Provider, which he will have already read when downloading the Application and which he will be required to accept again.

3. Access to Paid Services and Withdrawal
3.1 Access and Limitation
Access to the Paid Services on the Site will be activated after validation and payment of the order, by providing a username and password. The Customer will be able to access, by logging in on the Site, the Paid Services ordered and paid for. Access to the Paid Services on the Applications occurs after payment has been made on the Application, on the Customer's Android platforms, Apple Store or Payment Service Provider account, but can also be done by linking, within the Application, to the account opened on the Site in order to benefit from the paid services that have been subscribed to on the Site. Indeed, while the use of the Customer's account is strictly individual, no account sharing being accepted, the Customer is entitled to use, in a non-simultaneous manner, the Paid Services on several devices, on the basis of a single subscription.
The Licensee acknowledges that the use of the Paid Services does not include any installation, adaptation, customization, or training services: such services, if required, will be billed separately upon request by the Licensee to the Licensor.
3.2 Withdrawal
Concerning the orders made on the Site, the Customer benefits, beyond even the legal prescriptions, from a right of retraction of 30 (thirty) days from the day his order has been completed. The Customer can thus during this period, without attesting to any reason, go back on his commitment by sending to the Publisher, ideally with acknowledgement of receipt, a letter or an e-mail in that sense and without any ambiguity. A standard withdrawal form, which is only an example, is communicated to the Customer in the appendix. The refund will then take place within 14 (fourteen) days.
With respect to orders for Paid Services placed on the Applications, Android platforms, Payment Service Provider or Apple Store terms of use apply.
In this respect, the Customer ordering services on the Apple Store as well as on Android platforms expressly acknowledges, due to the nature of the subject matter of the contract (access to and use of Products requested by the Customer prior to any exercise of a right of withdrawal), that withdrawal is excluded when the download of the Paid Services takes place at the time of the order on the Apple Store and that the services ordered on Android platforms or Payment Service providers are also immediately available.
During the realization of the various stages mentioned above of the order, the Customer commits himself to respect the present contractual conditions.
The Publisher reserves the right to refuse the order for any legitimate reason and in particular if it is abnormal, placed in bad faith or when there is a dispute with the Customer concerning the payment of a previous order.
4. Price and payment
4.1 Price
To access and use the Paid Services, the Customer must pay the price corresponding to the service in question and to the duration of the subscription chosen.
The price of the subscription allowing access to and use of the Paid Services is specified on the current price list available on the Site or on the Application and mentioned again at the time of the order; it includes all taxes.
The Paid Services correspond to:
· the cost of granting this License for the use of the Site and Applications;
· if applicable, the cost of support, usage statistics, hosting, and bandwidth for the use of the Software.
All other services are not included in the Price, including any potential installation, adaptation, customization or training fees: such services, if required, will be billed separately upon request by the Licensee to the Licensor. In this regard, the telecommunication fees related to access to the Site or the Application shall remain the sole responsibility of the Client. The validity period of the offers and prices is determined by the updating of the Site and the Applications.
4.2 Payment
On the Site and Applications, the payment of the total price by the Customer is carried out by credit card or debit cards, Apple Pay, WeChat Pay or Alipay via third party Payment Processing Providers. The accepted credit or debit cards are those supported by the third parties payment processing providers
Where applicable, the transaction is immediately debited from the Customer's digital wallet or bank card after verification of the card's data, upon receipt of the debit authorization from the company issuing the digital wallet or bank card used by the Customer.
The commitment to pay by means of a digital wallet or payment card is irrevocable. By providing his digital wallet or credit card information, the Customer authorizes the payment provider to debit his digital wallet or credit card for the amount corresponding to the total price.
To this end, the Customer confirms that he is the holder of the digital wallet or bank card to be debited and that the name on the bank card is indeed his. The Customer communicates the sixteen digits and the expiry date of his credit card as well as, if necessary, the numbers of the visual cryptogram.
In the event that it is impossible to debit the total price, the order will be immediately canceled by right.
The Licensor makes every effort to ensure the confidentiality and security of data transmitted on the Site. The Customer is informed that when paying by digital wallet or credit card, the Licensor uses the services of a service provider who is responsible for ensuring the safety of the payment transaction; the Publisher does not have access to the Customer's credit card numbers which are not stored at the Publisher but at the payment provider. Moreover, when subscribing to paid Services on the Applications, the Publisher does not handle the payment operations, which depend on the platforms or Payment Service Provider.
5. Duration of access and renewal
Access to the Paid Services begins on the day of payment of the order for the duration chosen by the Customer when ordering. For certain Paid Services, individual subscriptions are automatically renewed on the expiration date; the user may at any time, up to and including the day before the renewal, disable this renewal from the interface of his profile, under the section "Subscriptions", or, in the context of the Applications, on the page for managing purchases and/or subscriptions provided by Apple Store (Settings > Apple ID), Android platforms or Payment Service Provider.
The User will be informed of the deadline for objecting to the renewal of the subscription by e-mail, at the earliest 3 months and at the latest 1 month before the annual subscription renewal date.
It is expressly agreed between the Parties that IMAIOS reserves the right to modify its rates and access conditions from one period to another.
In addition, certain Paid Services may be subscribed to for an indefinite period: IMAIOS may not request a new paid subscription for these services, but does not commit to ensuring that these services, or the Application on which they are located, remain available.
6. Applicable contract documents
By using the IMAIOS’ Site and the Applications, the Licensee accepts, without reservation, the Conditions of access and use of the Site and Applications available on the IMAIOS site in free access and on each Application, as well as the Licensor's Privacy Policy. In the event of a conflict between the general terms of use and the present contract, the latter shall prevail. Furthermore, the Customer using the Applications is subject to the terms of use of the platform used, namely Android platforms, Payment Service Provider or Apple Store. In the event of a conflict between those conditions and the present terms and conditions, the latter shall prevail.
7. Termination
In the event of a breach by either party of any of its contractual obligations, this agreement may be terminated at the request of the injured party, in the absence of an amicable agreement, after formal notice to perform has been served by registered letter with acknowledgement of receipt which has remained unsuccessful for a period of thirty days, simply by sending a registered letter with acknowledgement of receipt notifying said termination. In the event that the Licensee fails to comply with its obligations, no refund of the price paid, corresponding to the remaining period of the subscription, will be granted.
8. Miscellaneous provisions
Unless proven otherwise, the data recorded on the page "My Account" of the Site constitutes proof of all Orders placed on the Site, and the Customer may thus access the history of orders placed at any time. Similarly, orders placed on the Applications are visible on the Apple Store, Android or Payment Service Provider platforms.
The Customer may access the contracts binding the parties at the time of the order (Subscription Conditions, Privacy Policy, Terms and conditions of access and use of the Site and Applications) on the Site and via links within the Applications. The Customer may download these contracts and keep them in a durable manner on any other medium of his choice.
This Agreement shall be binding upon and inure to the benefit of the parties and their respective successors in interest. Licensee may not assign its rights, obligations or privileges hereunder or under any law, except with the prior written consent of Licensor.
The translation of the Conditions into any other language is provided for information purposes only. In the event of any inconsistency between the translated version and the English version, the English version shall prevail and be the only version that is binding on both parties and governs the relationship with the Publisher.
This contract and its interpretation are subject to the PRC law and the parties acknowledge the exclusive jurisdiction of the people’s court in Shanghai at the place where the Publisher is registered at.

Introduction
This e-Anatomy anatomical module is dedicated to the anatomy of the knee showing the normal MRI appearance of the ligaments, menisci, tendons and other structures of the knee joint on a high-resolution 3T MRI (multiplanar PD-FS and T1 images).
Magnetic resonance imaging (MRI) of the knee is indicated for various clinical scenarios, particularly when initial radiographs are inconclusive or when detailed soft tissue evaluation is required. The American College of Radiology (ACR) provides comprehensive guidelines on the appropriate use of MRI for different knee conditions.
1. Chronic Knee Pain: MRI is indicated when initial radiographs are normal or show joint effusion, but pain persists. It is particularly useful for detecting effusions, synovitis, popliteal cysts, subchondral cysts, articular cartilage, and meniscal pathologies.
2. Acute Trauma: In cases of acute knee trauma with negative radiographs, MRI is valuable for the diagnosis of soft tissue injuries, including ligament tears (e.g., anterior cruciate ligament [ACL], posterior cruciate ligament [PCL]), meniscal tears, and bone marrow contusions. It can also identify occult fractures and internal derangements.
3. Suspected Osteoarthritis: MRI can be used to assess the extent of osteoarthritis, particularly when evaluating cartilage loss, bone marrow lesions, and other degenerative changes not well visualized on radiographs.
4. Meniscal and Articular Cartilage Lesions: MRI is indicated for diagnosing meniscal tears and articular cartilage lesions.
5. Anterior Knee Pain: MRI is useful for evaluating anterior knee pain, which may be due to chondral lesions, patellar instability, tendinopathies, and other soft tissue or osseous abnormalities.
6. Postoperative Evaluation: MRI is indicated for evaluating complications after knee surgeries, such as total knee arthroplasty, and to assess soft tissue abnormalities, including tendinopathy, arthrofibrosis and periarticular masses.
These indications highlight the utility of MRI in providing detailed imaging of knee structures, facilitating accurate diagnosis and guiding appropriate management.
Material and methods
This MRI of the knee was performed on a healthy female patient using a Siemens 3T MRI.
Magnetic resonance imaging (MRI) of the knee employs various sequences and planes to provide comprehensive evaluation of joint structures. The primary sequences used include:
1. Proton Density with fat suppression (PD-FS): for evaluating meniscal tears, ligament injuries, and cartilage abnormalities and providing high contrast between different tissues.
2. T1 turbo spin echo (TSE): better delineation of some anatomical structures like muscles and tendons.
The primary imaging planes used in knee MRI are:
1. Sagittal Plane: for evaluating the anterior and posterior cruciate ligaments, menisci, and cartilage.
2. Coronal Plane: for assessing the collateral ligaments, menisci, and overall joint alignment.
3. Axial Plane: used to evaluate the patellofemoral joint, menisci, and the extent of any soft tissue abnormalities.
The anatomical structures were labeled by Antoine Micheau M.D. (Radiologist, Montpellier – France), following Terminologia Anatomica 2.
