Rotator Cuff Fatty Infiltration Are Coronal Images More Helpful for Characterization than Sagittal Images?

Objective: To assess for a difference in the characteriza - tion of rotator cuff (RC) muscle fatty infiltration (FI) between the sagittal and coronal planes in the setting of a large or massive RC tear.

Materials And Methods: Retrospective review of pa - tients with MRIs demonstrating large or massive RC tears (study group-SG) and no tearing (control group-CG) was conducted. Sagittal T1W and coronal PD images of the supraspinatus and infraspinatus muscles from each patient were selected, separated, and placed in random order.

Current Clinical Applications and Future Potential of Diffusion Tensor Imaging in Traumatic Brain Injury.

In the setting of acute central nervous system (CNS) emergencies, computed tomography (CT) and conventional magnetic resonance imaging (MRI) play an important role in the identification of life-threatening intracranial injury. However, the full extent or even presence of brain damage frequently escapes detection by conventional CT and MRI. Advanced MRI techniques such as diffusion tensor imaging (DTI) are emerging as important adjuncts in the diagnosis of microstructural white matter injury in the acute and postacute brain-injured patient.

Misses and errors in upper extremity trauma radiographs.

Objective: The article reviews a select group of traumatic upper extremity injuries that can be easily misinterpreted on radiographs.

Conclusion: The awareness of these specific injuries and an understanding of their underlying pathophysiology and the role that radiographs can play in their evaluation will give the reader the best opportunity to make the important imaging findings and guide appropriate treatment.

Retroperitoneal hemangioma demonstrated on blood pool scan.

Retroperitoneal hemangioma is a rare but clinically significant condition that can be challenging to diagnose and characterize on anatomical imaging alone. We present a case of an 80-year-old woman with diabetes and hypertension, who was found to have an abdominal mass diagnosed first on CT abdomen and pelvis in March 2011 and demonstrated to be stable on subsequent MRI study performed 16 months later in July 2012. The mass was later confirmed to be a hemangioma on a 99mTc-red cell study.

Magnetic resonance spectroscopic imaging of benign prostatic tissue: findings at 3.0 T compared to 1.5 T-initial experience.

In a retrospective study of 71 voxels of benign peripheral zone tissue from 3 men who underwent endorectal magnetic resonance (MR) spectroscopic imaging of the prostate at both 1.5 and 3 T, 21 voxels that appeared more malignant at 3 T to either of two readers demonstrated significantly higher levels of choline and polyamines at 3 T compared to 1.5 T using a Wilcoxon ranked-sum test; awareness of this selective amplification of these metabolic signals at high field strength may help avoid overdiagnosis of prostate cancer.
