Background: Musculoskeletal injuries of knee are commonly encountered in sportsmen during sports activities. Magnetic resonance imaging (MRI) is the modality of choice for evaluation of traumatic knee injuries and arthroscopic interventions. By knowing the pattern and burden of surgically significant injuries in sportsmen, the artificial intelligence (AI) software may be developed accordingly so that surgically significant injuries may be identified by the young radiologists. Methods: It was a retrospective study on MRI for knee injuries in sportsmen. The digital data from Radiology department at a zonal level hospital was analysed. The MRI findings were correlated with the arthroscopic records available. For surgically insignificant injuries, the literature was referred for the typical MRI findings of the injuries. Results: Of 272 cases of MRI knee, 74.3% cases were detected to have acute traumatic injuries. Among various types of injuries found in this study, anterior cruciate ligament (ACL) tear (55.9%) was the commonest injury followed by medial meniscal tear (40%). 40 (19.8%) cases were found to have surgically significant MRI findings which were subsequently corroborated with knee arthroscopy.Conclusions: Since majority of soft tissue injuries of knee constitute ACL and meniscal tears, the industries involved in developing AI software for soft tissue injuries of knee, should primarily focus on identification of ACL and meniscal injuries. The AI software may also be helpful for the young radiologists in early training days in MRI for knee injuries and may also help in big scale research projects of post traumatic MRI knees.

With advances in magnetic resonance imaging (MRI) technology and observer experience, MRI is an established part of the diagnostic work-up for soft tissue injuries of the hand and wrist. It potentially minimizes the need for invasive procedures such as arthrography or arthroscopy. However, there are limitations of MRI, and many patients who undergo MRI of the wrist still need wrist arthroscopy for both diagnostic and therapeutic purposes. A review of the recent literature of the role of MRI in the assessment of soft tissue injuries of the hand and wrist is presented.

Magnetic resonance imaging has become the gold standard for soft tissue lesions evaluation especially after a traumatic event where there is need for diagnostic confirmation. The objective of the current paper was to evaluate the ability of magnetic resonance imaging in diagnosing soft tissue lesions in patients who underwent anterior cruciate ligament reconstruction compared with arthroscopic findings. Through the ability to diagnose soft tissue injuries, particularly meniscal lesions, magnetic resonance imaging should be considered as fundamental in guiding therapeutic management in patients with anterior cruciate ligament lesions.

Abstract Background. Dermatofibrosarcoma protuberans (DFSP) of the vulva is a rare low-grade soft tissue sarcoma. Magnetic resonance imaging (MRI) findings of vulvar DFSP were essentially unreported in the literature. Case report. We report a DFSP of vulva with its clinical, histological and MRI features. As far we know this is the first case of histologically confirmed vulvar DFSP presenting with MR images. The diagnosis of DFSP is usually made by histopathologic and clinical findings. Conclusions. MRI is useful both for the diagnosis of DFSP and following up the patients since it has high soft tissue resolution and no risk of radiation exposure. With MRI the relation to the adjacent anatomical structures, extension and depth of the tumour and possible lymph node involvement can also be demonstrated.

Background: With the increasing sport population, the number of patients with external snapping hip (ESH) has also increased. To detect and visualise pathological soft tissue changes, magnetic resonance imaging (MRI) has been 1 of the most useful modalities. However, only limited studies have investigated MRI and its clinical value in the treatment of ESH in the past. Materials and methods: Between May 2017 and November 2018, 104 patients were diagnosed with ESH at our institution. We excluded patients who did not undergo an MRI ( n = 11), had complaint of bilateral symptom ( n = 17), were not diagnosed hip problems previously (n = 2), and were lost–follow-up within 6 months ( n = 19). After applying the exclusion criteria, 55 patients remained. We classified the patients into 2 groups according–MRI findings: tensed iliotibial band (ITB) and hypertrophied gluteus maximus (GM). We investigated the clinical findings, such as mean age, symptom duration, pain score, grading based on symptom severity, and other radiological findings such as soft tissue signal change and ITB thickness. The variables were compared between the groups. Results: Between the 2 groups defined by MRI findings, the group characterised by tense ITB showed a relatively short symptom duration than the hypertrophied GM group ( p < 0.001). No significant differences in the other variables were found between the groups. Conclusions: ESH has 2 types of MRI features. Compared with the hypertrophied GM group, the tense ITB group showed a shorter symptom duration and a more reversible status.

The knee is a very important joint and injuries affecting it may cause significant disability and discomfort to the patient. Despite a variety of methods available to assess injuries of the knee joint, Magnetic Resonance Imaging (MRI) continues to play a major role. This study evaluated the spectrum of MRI findings in a relatively low resource environment, with limited access to MRI modality. The outcome should justify further investment in MRI services in this locality. The study involves retrospective analysis of MRI reports of 198 clinically symptomatic patients referred for imaging in a Port-Harcourt. All examinations were performed using GE BRIVO MR 235 machine with 0.35 Tesla field strength in a well-coupled standard knee coil. All images were analyzed for normality or otherwise and radiological reports generated by competent radiologists. The most common findings are traumatic in origin, notably cruciate ligament tears (37.37%) and meniscal tears (33.3%) as well as quadriceps tendon tears (3.03%). The medial meniscus and anterior cruciate ligaments were more frequently involved. Furthermore, patients in the 3rd and 4th decade of life were more commonly involved, with a male preponderance. The less common findings of Synovial chondromatosis, cyst-like lesions, tumors and loose bodies, all buttress the importance of routine MRI in atraumatic cases. The spectrum of MRI findings in this study is a reflection of growing interest and confidence in MRI of the diseased knee joint in our environment. The outcome would be a justification for future investments in MRI. Keywords: Magnetic Resonance Imaging, knee injuries, tibial meniscal tears, incidental findings

This article demonstrates normal anatomy of the foot and ankle as visualized with magnetic resonance imaging (MRI) in the sagittal, axial, and coronal planes. Additionally, selected cases chosen from our experience with more than 100 clinical scans are shown to highlight the primary areas in which we have found MRI to be clinically useful: bone marrow abnormalities, especially osteomyelitis and osteonecrosis, soft tissue injuries and masses, and cases in which metallic fixators make CT evaluation problematic.
