Clinical application of the MSCT in the diagnosis of renal malformation / 实用医学杂志

ABSTRACT

Objective To analyze the best methods for diagnostic scanning and image processing of multi-slice spiral CT (MSCT) in the detection of renal malformations (RM). Methods From June 2008 to Februany 2012, one hundred and four patients with kidney malformation received 64-slice MSCT assay were enrolled in our Hospital. Related materials of the patients were used for retrospective analysis. Diagnostic accuracy of urinary malformation were calculated on the image of axial and MPR, Curve, MIP, VR by MSCT unenhangced scanning, enhangced cortical phase scanning, enhangced parenchymal phase scanning and enhangced excretory phase scanning. Results One hundred and four patients with kidney abnormalities received the MSCT unhangced scan axial and MPR, Curve film, enhangced cortical phase scanning, enhangced parenchymal phase scanning, enhangced excretory phase scanning and MPR, MIP, VR film, respectively. The diagnostic accuracy were as follws renal dysplasia (72.73%, 81.82%, 81.82%, 72.73%), renal hypoplasia (83.33%, 91.67%, 95.83%, 100%), solitary kidney (100%, 100%, 100%, 100%), ectopic kidney (76.92%, 100%, 100%, 100%), horseshoe kidney (100%, 100%, 100%, 100%),misplaced renal lobe (0%,100%). Conclusion The MSCT with image post-processing techniques in the diagnosis of RM has its unique advantages, MSCT can be preferred as a method for renal malformation examination.
