Magnetic Resonance Neurography Evaluation in Children

The term WARP summarizes methods to minimize the impact of metal implants on MR image quality. This article introduces different techniques such as high bandwidth, VAT and SEMAC. [...]

Job’s Syndrome

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

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. [...]

MR Neurography – Diagnostic Criteria to Determine Lesions of Peripheral Nerves

MR Neurography is an excellent technique for visualization and evaluation of peripheral nerve disorders. In their article Philipp Bäumer et al. (Heidelberg University Hospital, Heidelberg, Germany) show high resolution intra-neural fascicular detail in both normal and abnormal states and cover different aspects including clinical indications, protocols, pitfalls, and useful applications. [...]

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. [...]

Myxoid Chondrosarcoma

This 65-year-old man presented to clinic with a tender mass in the anteromedial portion of his right midthigh which had enlarged over a year’s time. He further complained of nonspecific associated symptoms, including paresthesias and occasional temperature changes in his right leg. Following the illustrated MR examination, the patient was referred for evaluation by surgical oncology. [...]

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

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. [...]

Liposarcoma

This 56 year old man presented to clinic complaining of a mass within the musculature of his medial right thigh that had appeared approximately 5 months ago. The patient denied any associated pain or tenderness. On the illustrated MR examination, a mass was found which was confirmed as a liposarcoma by pathologic evaluation following its surgical removal [...]

Neurofibroma

This 35-year-old female presented to clinic complaining of pain and swelling posterior to her right knee of approximately 3 months duration. Physical examination confirmed the presence of a soft tissue mass in the patient’s right posterior lower leg. An MRI scan demonstrated a well-defined oval lesion, confirmed to be a neurofibroma by subsequent surgery. [...]

Fibroepithelial papilloma

This 46-year-old woman presented clinically with a complaint of gradual hearing impairment in the right ear for three years. Physical examination revealed the right parotid gland region to be swollen, with a medium-hard palpable mass. [...]
