Brain Perfusion; How & Why

Pathologic perfusion is sometimes the reason and often the consequence of brain pathologies. Evaluation of perfusion with dynamic susceptibility-weighted imaging is a well understood and established method to evaluate these changes. In this article, Binesh et al.

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. [...]

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. [...]

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 signal. 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. [...]

Takotsubo Cardiomyopathy

This 70-year-old woman presented to the emergency room with acute onset of severe chest pain. No prior history of trauma. The pain started after a quarrel with her 45-year old daughter. The electrocardiogram did not reveal evidence of ischemic ST segment deviations. Creatinine kinase was of borderline value (10 U/L), but cardiac troponin T was elevated (2.15 µg/L). Coronary artery disease was ruled out by emergency coronary angiography. However, left ventricular angiography demonstrated apical ballooning with a reduced left ventricular ejection fraction. [...]
