the user will have a better understanding of the pitfalls and sources of misdiagnosis in CT evaluation of the Kidney, Ureters and Bladder. Major teaching points include; 1.there is no single optimal phase (non-contrast, arterial, venous, excretory phase) for detecting pathology and a combination of phases is needed 2.routine use of multiplanar and 3D imaging is needed to detect and classify GU pathology 3.study protocols are critical for lesion detection and classification 4.misdiagnosis occur when assumptions are made without careful lesion analysis

1.Pitfalls in Imaging the GU Tract • results from the literature • sources of error in clinical practice with examples 2.Optimizing scan protocols to minimize error • role of specific phases in lesion detection and characterization 3.Designing interpretation strategies to minimize error • role of MPR and 3D imaging in minimizing error and misinterpretation • case studies illustrating specific errors and how they can be avoided with routine use of MPR and 3D 4.Select case studies illustrating specific pitfalls with recommendations to avoid these misdiagnosis 5.Discussion of study design and need to minimize radiation dose • challenges of lowering the dose in GU imaging • dose reduction and it may increase error rates
