PURPOSE To assess prospectively the role of magnetic resonance (MR) imaging in the staging of patients with a solitary bone plasmacytoma (SBP). PATIENTS AND METHODS Twelve consecutive patients with an apparent SBP underwent MR imaging of both the primary tumor and the thoracic and lumbosacral spine to seek additional foci of marrow involvement that might have been undetected by standard skeletal survey. All patients received megavoltage irradiation (total dose, 40 Gy) to the primary lesion. RESULTS MR imaging of the thoracic and lumbosacral spine showed additional foci of marrow replacement in four of 12 patients, with signal characteristics identical to those of the primary tumor. In all four patients, the abnormal protein persisted at greater than 50% of the pretreatment value following radiation treatment. In contrast, the myeloma protein disappeared or was reduced by greater than 50% in five of the six patients with secretory disease and without additional marrow abnormalities. One of four patients progressed to multiple myeloma 10 months after diagnosis with new lesions on conventional radiographs in the same areas as detected previously by MR imaging. CONCLUSION Four of 12 patients considered to have a SBP by standard criteria may have been understaged, because MR imaging showed additional marrow abnormalities consistent with myeloma. MR imaging of the spine may contribute to the initial staging of SBP, especially since some patients may be cured with radiotherapy.

Soft Tissue Masses

Evaluation of soft tissue tumours has undergone a dramatic change with the advent of ultrasonography(USG),magnetic resonance(MR)imaging and computed tomography (CT). Patients are referred for imaging to evaluate a soft tissue lesions in the trunk or extremities.These lesions range from non-neoplastic conditions to benign and malignant tumours. The primary goal for the imaging referral is to confirm the presence of a mass and to assess its extent. And also the study is an attempt to define the role of different imaging modalities in the evaluation of patients with soft tissue tumours in correlation with histopathology.

Objectives: The Patellofemoral joint (PFJ) is a complex joint structure with high functional and biomechanical requirements. The purpose of this study is to evaluate cause of patella-femoral joint instability with in-depth evaluation of influence of anatomical risk factors (AF), measurements and anatomical relationships of the patellofemoral joint and various pathologies causing medial patellofemoral ligament (MPFL) injury that contributes to the patellar maltracking using 1.5 Tesla magnetic resonance imaging. Materials and Methods: The present prospective study is carried out at department of radiology, shri M P Shah Medical College, Jamnagar. This is study of total 50 patients carried out in 12-month duration from July 2019 to June 2020, in which 50 patients aged between 8 - 68 years selected as study group presented with complaint symptoms of patellofemoral instability, knee pain and maltracking were examined and identified by an orthopaedic surgeon. Patients with the clinical suspicion of a PFJ maltracking were selected for subsequent MRI examination. Results: The age distribution in our study was in range of 8 years to 68 years with maximum population within 31 to 40 years range, 66 % were male and 34 % female. Their trochlear depth, sulcal angle, trochlear facet asymmetry, lateral inclination angle was found abnormal in 18 cases (36%), 8 (16%) showed patellar alta and 7 (14%) patella baja. Lateralization of patella (> 6 mm) was noted in 18 patients (36%), Medial patellofemoral ligament injuries were seen in 16 (32%) patients on MRI and kissing contusion 10 (20%) patients. A detailed understanding of the anatomy and pathology of the anterior knee compartment is essential for proper imaging interpretation and treatment management. Conclusion: Magnetic resonance (MR) imaging has been established as the method of choice, showing high accuracy in patellofemoral joint abnormalities. The present study aims to explore the role of MR imaging in diagnosing the various disorders located in anterior compartment of knee. Keywords: Joint instability, Patellofemoral joint, MPFL, MR imaging/diagnosis.

Fetal Mr

The techniques currently used by most specialist centres for magnetic resonance (MR) imaging of the fetus were developed in the 1990s, when fast imaging sequences capable of good soft tissue contrast were introduced. Earlier pioneering work on fetal MR imaging in the early 1980s revealed some promise for this application, but at the time it was not generally considered of diagnostic quality or clinical practicality because of the long acquisition times and inevitable image degradation resulting from fetal movement, problems which were overcome only by means of maternal sedation or neuromuscular blockade of the fetus. As with the early development of MR imaging in general, it is the ability to image central nervous system (CNS) tissues with a clarity and contrast far exceeding X-ray computed tomography and ultrasound that has shown the most benefit to date. Subsequent development of techniques for specific problem solving in other areas of the body will undoubtedly follow.
