Helical CT for detection and characterization of renal masses.
Helical CT permits the radiologist to image the kidney continuously, eliminating the chances of scanner misregistration. In addition, the kidneys can now be imaged during essentially any phase of contrast material enhancement. Although this offers greater flexibility to the imager, a number of potential problems with helical CT must be considered, particularly when it is performed during the cortical phase of renal enhancement. This article reviews both the advantages and potential pitfalls of helical CT when used for both detection and characterization of renal masses.
