Abstract:
Objective To compare diagnostic performance of ultrasound and radionuclide imaging in diagnosis of Meckel's diverticulum.Methods Totally 46 children suspected with Meckel's diverticulum were enrolled.Ultrasound,radionuclide imaging data were analyzed and compared with pathology.Results In 46 children suspected with Meckel's diverticulum,38 cases were confirmed by operation.Thirty-three cases of 38 were diagnosed Meckel's diverticulum by ultrasound,5 cases of 38 were false negative,there was no false positive case.Radionuclide imaging was positive in 24 cases of 46,false positive in 4 eases and false negative in 18 cases.The ultrasound diagnostic accuracy rate was 89.13％ (41/46),sensitivity was 86.84％ (33/38),specificity was 100％ (8/8).Diagnostic accuracy rate of radionuclide imaging was 52.17％ (24/46),sensitivity was 52.63 ％ (20/38) and specificity was 50.00 ％ (4/8).The sensitivity of ultrasound and radionuclide imaging in diagnosis of Meckel's diverticulum had significant difference (P＜0.01).Conclusion Ultrasound in diagnosis of Meckel's diverticulum has advantages of non-invasive,no radiation,acceptable price and high sensitivity.
