Job’s Syndrome

July 6, 2013 by
Contrast-enhanced MR imaging is a particularly sensitive method for detecting soft-tissue masses, providing as well precise localization and definition of extent. In his case report, G. Hadjidekov et al. (Sofia, Bulgaria) presents a rare immunodeficiency disorder known as Job’s syndrome. The case shows the usefulness of MRI to analyze skin disorders and deeper soft-tissue masses in various locations. [...]

Bone and Soft Tissue Tumor Imaging: An Overview

July 6, 2013 by
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. [...]

Assessment and Classification of Peripheral Vascular Anomalies by Time-Resolved MRA using TWIST

July 6, 2013 by
Vascular malformations are complex lesions with a variety of clinical manifestations. Time-resolved MRA combined with parallel imaging and echo sharing schemes represents a reasonable alternative to more invasive DSA for the evaluation of VMs. Therefore, time-resolved MRA can play an important role in categorizing these lesions and determining their extent in order to correctly guide treatment. [...]
