Abstract

PURPOSE
To determine the value of magnetic resonance imaging (MRI) using HASTE (half- Fourier single-shot turbo spin-echo) and true FISP (fast imaging with steady-state precession and heavy T2-weighting) sequences in diagnosing bowel obstruction.
MATERIALS AND METHODS
Thirty-one consecutive patients in whom suspected bowel obstruction was revealed at plain abdominal radiography, barium study, and computed tomography (CT) were admitted during an eight-month period. Eighteen of 27 in whom bowel obstruction was confirmed underwent MRI using HASTE and true FISP sequences.
RESULTS
At MRI, bowel obstruction was diagnosed in all patients. Using the HASTE sequence, the site of obstruction was correctly identified in 16 patients(89%) and the cause of obstruction was correctly diagnosed in 15(83%). Using the true FISP sequence, the corresponding figures were 16(89%) and 16(89%). Of the 18 patients with confirmed bowel obstruction, 33%(6/18) showed better lesion conspicuity at true FISP, for 39%(7/18), conspicuity was equal at both sequences, 28%(5/18) showed better conspicuity at HASTE.
CONCLUSION
MRI can be useful for evaluation the presence, site and cause of bowel obstruction. On comparing the findings of HASTE and true FISP sequences, no significant differences were observed.
