PURPOSE: To investigate the value of different postprocessing algorithms for multislice spiral CT (MSCT) in diagnosing @entity1151 . MATERIALS AND METHODS: Forty-eight @entity1 with suspected @entity1151 prospectively underwent MSCT using an 8-slice spiral CT. Using a confidence level on a three-point scale, three radiologists reviewed 2-mm and 5-mm axial slices, 5-mm and 10-mm axial @entity1213 ( @entity1213 ) and 2-mm coronal slices as well as interactively generated multiplanar reformatted images. A subsequent consensus reading of the primary 1.25-mm axial slices served as gold standard. ROC analysis was applied to the various vascular sections. RESULTS: The ROC analysis revealed a higher diagnostic accuracy of the 2-mm axial sections as compared to the 5-mm axial slices (Az = [0.988;0.976] vs. Az = [0.988;0.802]). Coronal and multiplanar reformations also showed excellent diagnostic accuracy (Az = [0.972;0.949] and Az = [0.997;0.951], respectively) and were significantly superior to the 5-mm axial slices through the segmental and subsegmental arteries (p=0.05). @entity1213 showed the weakest diagnostic accuracy (Az = [0.967;0.802] for 5-mm @entity1213 ; Az = [0.879;0.781] for 10-mm @entity1213 ). CONCLUSION: Thin axial slices as well as coronal and multiplanar reformations are superior to thick axial slices in the diagnosis of @entity1151 . @entity1213 is not suited for accurate diagnosis of @entity1151 .
