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 ANDMETHODS:
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.
