Abstract

OBJECTIVE

Our aim was to determine whether fast MR imaging using the half-Fourier acquisition single-shot turbo spin-echo (HASTE) MR sequence is accurate for diagnosis of small-bowel obstruction.

MATERIALS AND METHODS

Forty-three nonconsecutive patients with suspected small-bowel obstruction were evaluated with HASTE MR imaging during a 12-month period. Images were retrospectively assessed for the presence, level, and cause of bowel obstruction. Data were compared with results of conventional radiography and findings at surgery when available.

RESULTS

Of the 43 patients imaged, 29 patients had small-bowel obstruction revealed by unenhanced or contrast-enhanced radiography or by CT. Surgical confirmation was available in 21 patients. Small-bowel obstruction was shown by HASTE MR imaging in 26 (90%) of these 29 patients. HASTE MR images showed the correct level of obstruction in 19 (73%) of the 26 patients and showed the cause of obstruction in 13 (50%) of the 26 patients.

CONCLUSION

With a high degree of accuracy, HASTE MR imaging can show the presence and level of small-bowel obstruction.

摘要

目的

我们的目的是确定使用半傅里叶采集单次激发快速自旋回波（HASTE）磁共振序列的快速磁共振成像对小肠梗阻的诊断是否准确。

材料与方法

在12个月期间，对43例疑似小肠梗阻的非连续患者进行了HASTE磁共振成像评估。对图像进行回顾性评估，以确定肠梗阻的存在、部位及病因。将数据与传统放射学检查结果以及手术所见（若有）进行比较。

结果

在接受成像的43例患者中，29例患者经平扫或增强放射学检查或CT检查显示存在小肠梗阻。21例患者有手术证实结果。在这29例患者中，HASTE磁共振成像显示26例（90%）存在小肠梗阻。HASTE磁共振图像在26例患者中的19例（73%）显示了梗阻的正确部位，在26例患者中的13例（50%）显示了梗阻的病因。
