Abstract:
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.
