Hydro-MRT mit schnellen Sequenzen bei Morbus Crohn: Vergleich mit der fraktionierten Magen-Darm-Passage

2008

PURPOSE To compare the value of hydro-MRI with that of barium studies in patients with Crohn's disease. MATERIALS AND METHODS After an oral bowel opacification using 1000 ml of a 2.5% mannitol solution, axial and coronal breath-hold sequences (T2W HASTE +/- FS, contrast-enhanced T1W FLASH FS) were acquired in 46 patients with Crohn's disease at 1.0 T. The findings of hydro-MRI were compared with those of barium studies. RESULTS In the stomach and the small bowel, hydro-MRI and barium studies demonstrated similar numbers of Crohn's involvements (39 vs. 36); in the colon, hydro-MRI showed clearly more affections (23 vs. 10). Hydro-MRI showed 12.7 cm of inflamed bowel per patient, on average (…

Beurteilung der entzündlichen Aktivität des M. Crohn mit der Hydro-MRT∗

2000

PURPOSE: To assess the value of hydro-MRI in the assessment of the activity of Crohn's disease. MATERIALS AND METHODS: After an oral bowel opacification using 1000 ml of a 2.5% mannitol solution, axial and coronal breath-hold sequences (T2W HASTE +/- FS, contrast-enhanced T1W FLASH FS) were acquired in 63 patients with Crohn's disease at 1.0 T. The enhancement of the bowel wall was correlated with other MRI findings, with the Crohn's disease activity index (CDAI), and the C-reactive protein (CRP). RESULTS: In Crohn's disease, contrast enhancement of the affected bowel wall is markedly increased in comparison with the normal bowel wall (+80 +/- 23% vs. +43 +/- 11%; p = 8 x 10(-11)). Positive…

Eine Mannitollösung als orales Kontrastmittel in der pelvinen MRT

1995

PURPOSE Improvement of pelvic MRI using peroral administration of an aqueous mannitol solution. METHODS We retrospectively evaluated magnetic resonance examinations of 72 patients with suspected or proven pelvic abnormalities: In 36 patients, no bowel marking was carried out. In further 36 patients, we performed a contrast enhancement of the bowel by oral application of 1000 ml of an aqueous mannitol solution. RESULTS 8/36 (22%) patients suffered from diarrhoea, nausea or meteorism as a result of mannitol application. In group 2, an excellent bowel marking of the small intestine could be obtained in 36/36 (100%) patients. Contrast enhancement of the bowel significantly improved delineation …
