Techniques that rely on separate acquisitions to obtain separate fat and water images are prone to misregistration artifacts because of motion, but combining these sequences with a motion-correction algorithm can result in robust fat suppression in reasonable scan times [170].

Bouysset M, Tebib J, Tavernier T, et al. Paralabral cysts on conventional MRI are considered to be an indirect sign of acetabular labral tears (9), even if such a tear is not discretely visualized; in such a setting, MR arthrography is usually recommended to further investigate for a labral tear.

However, with advances in MR imaging hardware technology, MR arthrography is now largely redundant and, with sufficient experience, the diagnosis can be made on conventional MR imaging with relative confidence (75%83% sensitivity and 75%100% specificity, depending on the experience of the reporter).

Spin-echo, fast spin-echo, or gradient-recalled T1-weighted images with fat suppression are used for contrast-enhanced MR sequences [52,60] At least 1 fluid-sensitive sequence is still necessary when performing MR arthrography to detect extra-articular pathology, as well as at least 1 T1-weighted sequence without fat suppression for evaluating bone marrow and characterizing soft-tissue lesions. Biomechanical alterations following corrective or tumor-removal surgery may be a reason for the development of some impingement syndromes; it is important to become familiar with their MRI findings as they might explain persistent or new onset pain following such surgery. Pediatr Radiol 49, 16911701 (2019). Acute ankle trauma [7,55,120,121] Such an extension of fluid-signal on MRI should alert the radiologist for the possibility of this overuse injury. It serves as the primary stabilizer of the axially loaded ankle. Currently, it has a diagnostic and therapeutic role (when combined with anesthetic and/or corticosteroid injection) in localizing the source of pain [11,12] prior to MR arthrography of the ankle [13]. First proposed in 2011 (13), iliopsoas impingement is currently considered to be an extra-articular type of hip impingement syndrome (14), which is being increasingly recognized.

These sequences complement short-TE (T1-weighted or proton-densityweighted) ones for plantar fascia and tendon imaging [37,41,81,150] and are especially important to compensate for magic angle artifact seen in tendons [155].

Do CT scans aid assessment of distal tibial physeal fractures? 68. Bags of distilled water or sat pads may be necessary to achieve homogeneous spectral fat suppression because of the field heterogeneity accentuated by the off-center position and irregular airsoft-tissue interfaces often encountered when imaging the ankle and hindfoot [164]. Erickson SJ, Cox IH, Hyde JS, Carrera GF, Strandt JA, Estkowski LD. For routine ankle and hindfoot studies, a FOV of 16 cm or less is desirable for detecting most clinically relevant disorders. Injuries of the deltoid ligament of the ankle are increasingly recognized with the widespread use of magnetic resonance (MR) imaging. Mengiardi B, Pfirrmann CW, Schottle PB, et al. Additionally, CT can be used for diagnosis of bone and soft-tissue injuries when there is a contraindication to MR imaging [25,26]. 2008;9:39. Bencardino J, Rosenberg ZS, Beltran J, et al.

Dry needling of the abnormal soft tissue with an intra-articular injection of cortisone and local anaesthetic may be performed under ultrasound guidance, allowing a return to previous levels of activity, even in elite athletes, but this technique has not been evaluated in the literature. 95.

Various techniques are useful to minimize artifacts that can degrade image quality. The equipment and medications should be monitored for inventory and drug expiration dates on a regular basis. Allowing the patient to plantar flex the ankle avoids aliasing of the toes onto the heel when the phase direction is oriented along the long axis of the foot [148]. The ultimate judgment regarding the propriety of any specific procedure or course of action must be made by the practitioner in light of all the circumstances presented. 2003;181(6):1551-1557. The physician performing MRI interpretation must have a clear understanding and knowledge of the anatomy and pathophysiology relevant to the MRI examination. Close. There was no evidence of avascular necrosis on the frontal radiograph of the hips (a) and coronal fat-saturated T2-weighted images (b, c; I, ischium; F, femur). J Bone Joint Surg Br. There is no established clinical examination test suggesting ischiofemoral impingement; however, external rotation of the hip with extension and adduction decreases the ischiofemoral space (24) and such a maneuver may elicit or increase pain in persons with this condition.

Examinations that use techniques not approved by the Food and Drug Administration, such as the intra-articular injection of gadolinium chelates (direct MR arthrography) [180], can be considered when they are judged to be medically appropriate. Semin Musculoskelet Radiol. Pictorial review: MRI features of foot and ankle injuries in ballet dancers. At least in cadaveric ankle studies, images obtained with a 3T scanner may have higher accuracy for articular cartilage abnormalities in the ankle compared to those obtained with 1T or 1.5T scanners [140,141]. Sussman WI, Han E, Schuenke MD. Ligamentous and capsular tearing and the resultant microinstability and haemorrhage following an ankle sprain may lead to reactive synovial hyperplasia and scarring in the anterolateral gutter. It may be possible to shorten the time required for an ankle or hindfoot MR examination without compromising diagnostic yield. Iliotibial band friction syndrome results from the compression of the distal iliotibial band against the lateral femoral epicondyle during intense physical activity (i.e., repetitive knee flexion and extension as in running, cycling, rowing, and skiing) (29).
