MSK Imaging Tips and Tricks

Mark Lourensz from the MRI Department at St. Vincent’s Hospital in Melbourne, Australia shares tips and tricks on a broad range of musculoskeletal topics extending from standard joint MRI to whole limb tumor evaluation. Some of these may be common sense, but it doesn’t hurt to revisit the basics occasionally. [...]

Bone and Soft Tissue Tumor Imaging: An Overview

Tumor imaging can be daunting, given the high stakes involved with a missed diagnosis or mis-diagnosis resulting in unnecessary further investigations, biopsies or even surgeries. In their article Marcus Pianta, Mark Lourensz et al. (St. Vincent’s Hospital, Fitzroy, Australia) describe their routine imaging protocol targeted to bone and soft tissue lesions, describe reporting and what the referring physicians need to know. [...]

MRI of the Shoulder: Utilizing the Glenoid Clockface Orientation

Orthopedic surgeons describe the glenoid fossa as the face of a clock, with the longitudinal axis defined by the supraglenoid tubercle at the 12:00 position and the inferior margin of the glenoid at the 6:00 position. Orienting the shoulder MRI exam relative to this clockface is ideal as it results in images which consistently correspond with the arthroscopists’ perspective and optimally profiles the major anatomic structures of the glenohumeral joint. In this article, Steven D. Needell, M.D. describes how to use the technique and shows its advantages in clinical cases. [...]

Long Bone Imaging

In this step-by-step guide divided in two articles, James Hancock of Benson Radiology in Adelaide, Australia, shows how to image the distal and proximal lower limbs using the Tim User Interface. This demonstration takes you through an examination including positioning the patient, running the localizers, and setting up fields-of-view and slice positions. Helpful tips and screenshots make this a valuable tool. [...]

MAGNETOM Skyra: The Mannheim Perspective

For over one year the 3T MAGNETOM Skyra has been used for scientific projects and clinical imaging at the University Medical Center (UMM) Mannheim. The UMM Mannheim was the first site in the world to install the Skyra. [...]

Advantages of MSK Imaging at 3 Tesla with special focus on Spine and Tumor Imaging.

The clinical advantages of upgrading to higher field strength (3T) magnets, improving coil technology, and using larger bore-sizes are proving to be significant. Through 10 case studies, it is suggested that the use of 3T open bore system with TrueForm technology can improve the diagnostic potential, as well as widen the indications, of MRI. The cases illustrate advantages of musculoskeletal imaging with a special focus on spine and tumor imaging. [...]

Metastatic Melanoma

This 36-year-old patient presented in December 2006 with a suspicious mole on the right lower leg which was surgically removed. Histopathology demonstrated a malignant melanoma. 2.5 years later the patient presented with an inguinal lymph node metastasis on the right side detected on lymph node dissection. MRI was ordered to further evaluate the right leg on which additional cutaneous lesions were noted. [...]

Nonsecretory Multiple Myeloma MRI Monitoring of Therapy Response

Multiple myeloma is a malignant hematologic disorder characterized by the infiltration of neoplastic plasma cells into bone marrow. Detection of medullary involvement is best accomplished with the aid of MRI. Visualization of myeloma burden at baseline and during therapy is beneficial for improved patient management and accurate prognostic evaluation. Therefore, whole-body imaging protocols are mandatory, especially for assessment of myeloma infiltration in all bone marrow cavities (medullary involvement) as well as for diagnosis of extramedullary involvement.
