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.

Techniques in Pediatric MRI – Tips for Imaging Children
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.

Clinical Lung Imaging
MRI of the lung can be applied in a variety of clinical scenarios. It is a feasible alternative to CT– as it avoids unnecessary radiation in young patients and provides additional physiological information such as perfusion or respiratory dynamics. Diffusion-weighted imaging can even add biological information about cell density.
In this report, Professor Biederer (University Hospital Kiel, Germany) gives a detailed review on lung imaging protocols and an insight into typical applications for lung MRI.
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.
Cerebral Amyloid Angiopathy (CAA)
using Susceptibility-Weighted Imaging
(syngo SWI)
Nephroblastoma – also known as Wilms tumor – is the most frequent renal malignancy in childhood with the highest incidence of this tumor within the fourth year of life. 80% of patients are less than 5 years old, however it is a rare condition in neonates (<1%).
3T MR Imaging of Peripheral Nerves Using 3D Diffusion-Weighted PSIF Technique
High-resolution magnetic resonance (MR) Neurography is a novel imaging technique, which enables multiplanar imaging of peripheral nerves, as well as diagnosis and localization of entrapment and non-entrapment peripheral neuropathies related to etiologies, such as inflammation, tumor and trauma.

This is a pictorial review of susceptibility- weighted imaging (syngo SWI) using a MAGNETOM Trio system with software version syngo MR B15 and a 32-channel head coil at The Geelong Hospital, Victoria, Australia. syngo SWI is a 3D FLASH sequence that is flow compensated in slice, read and phase directions.
Assessment and Classification of Peripheral Vascular Anomalies by Time-Resolved MRA using TWIST.
Vascular malformations (VM) are complex lesions present in various anatomical locations with a variety of clinical manifestations. Time-resolved MRA combined with parallel imaging and echo sharing schemes offer a reasonable alternative to more invasive diagnostic methods such as digital subtraction angiography (DSA) in evaluation of VMs. MRI is becoming the imaging modality of choice in assessing morphological issues regarding VMs. Time-resolved MRA can play an important role in characterizing these lesions and can influence therapeutic decision-making.
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.
Image Quality Improvement
of Composed MR IMages by Applying a Modified Homomorphic Filter.
Currently when obtaining systematic aspects of diseases with MRI, acquiring information from large body regions requires large fields-of-view (FOV) and multi-channel coils. However, images with large FOVs are characterized by inhomogeneous illumination. This becomes even more problematic at higher field strengths. By using a simple and robust post-processing approach, the signal inhomogeneity can be improved in times when large FOVs need to be obtained.
