| 目的 探讨64层螺旋CT冠状位多平面重建(MPR)在肠梗阻病因诊断中的价值。方法 对38例临床确诊为肠梗阻患者的64层螺旋CT图像行横断位及冠状位图像重建,由两组共4位医师独立阅片,先单独分析横断位、冠状位图像,而后结合二者阅片;阅片结果与手术和病理结果进行对照。结果 64层螺旋CT冠状位MPR诊断肠梗阻的病因与横断位图像具有等同的价值,均具有较高的准确性(分别为86.84%和89.47%);二者结合(先看横断位像后看冠状位像及先看冠状位像后看横断位像)阅片明显提高了诊断准确率(均为94.73%),增加了诊断信心。结论 64层螺旋CT冠状位MPR对诊断肠梗阻具有较高的临床应用价值,与横断位图像相结合可提高诊断准确性。 |

| Objective To assess the value of coronal MPR of 64-slice spiral CT in investigation of the cause of bowel obstruction. Methods Thirty-eight patients with different kinds of bowel obstruction underwent 64-slice spiral CT examination, and the data of axial and coronal image were reconstructed. Then the images were analyzed respectively by 4 readers in group A and B. Doctors in one group viewed the axial images first, then the coronal images, while in the other group viewed the coronal images first and then the axial images. The CT findings were compared with the surgical and pathologic results. Results The accuracy of coronal MPR of 64-slice spiral CT for investigating the cause of bowel obstruction was similar to that of axial MPR (86.84% vs 89.47%), and both had high accuracy. Diagnostic accuracy and confidence of doctors were improved obviously with the combination of axial images and coronal images (both 94.73%). Conclusion Coronal MPR of 64-slice spiral CT has very high clinical application value for diagnosing bowel obstruction. Diagnostic accuracy and doctors’ confidence are improved with the help of axial images. |
