Magnetic resonance enterography (MRE) and abdominal ultrasound are integral parts of multimodality assessments for patients with inflammatory bowel disease. Applications include assessing Crohn's disease (CD) extent and severity, differentiating CD from ulcerative colitis, detecting CD complications, evaluating response to therapy, and demonstrating postoperative recurrence. Magnetic resonance ...

BACKGROUND AND GOALS Magnetic resonance (MR) enterography provides the advantages of conventional enteroclysis and those of cross-sectional imaging. Adequate luminal distension, combined with ultrafast sequences, results in excellent delineation of mural and extramural manifestations of Crohn's disease. Recent technical advances, including ultra-high-field strength MR with its capability to pro...

lipomatosis of the nerve, also known as fibrolipomatous hamartoma, is characterized by the infiltration of the nerve by fibro-fatty tissue. the affected nerve becomes thicker, and it simulates a mass lesion. lipomatosis usually affects the median nerve and lipomatosis of the sciatic nerve is extremely rare. magnetic resonance imaging (mri) is the key to diagnosis, and it is usually pathognomoni...

conclusion these data indicate that while ce-mri will depict more positive results, there are cases in which dwi will show a positive result while ce-mri is negative. we suggest that the combination of these two imaging modalities might yield more positive results in diagnosing acute ms attack giving rise to a more accurate diagnosis. results ce-mri yielded positive results for 61 (87%) patient...

the application of magnetic resonance to diagnostic medical imaging stands as one of the great scientific achievements in the past 50 years. magnetic resonance techniques are easily applied to organs which remain stationary during the imaging procedure, such as the brain and musculoskeletal system. imaging of moving heart structures and circulating blood is considerably more difficult.   clinic...
