Renal Cell Carcinoma (RCC) is the most common tumor of the kidney, accounting for 80% to 85% of all malignant renal tumors and 2% to 3% of all malignant diseases in adults. Currently, with the widespread use of cross-sectional imaging, most RCCs are detected incidentally in asymptomatic patients. The role of imaging is central to detection, staging, and treatment of the RCC. Multidetector computed tomography (MDCT) is primarily used for detecting and staging of RCCs, however, improved equipment and pulse sequence techniques has resulted in similar accuracy of MR imaging compared with those of CT scanning. MR imaging offers inherently exquisite tissue contrast, which allows characterization of hemorrhage, fat, and subtle enhancement, making it particularly useful when ultrasonography or CT are inconclusive. In addition, contrast-enhanced MR imaging can be helpful for the determination of the histologic subtype in RCC. Furthermore, determination of the extent of tumor is critical for selection of optimal therapy and surgical approach, particularly in case of nephron-sparing surgery. After surgery, contrast-enhanced CT or MR imaging may be used to evaluate for early postoperative complications, including hemorrhage or urinary leak, in those patients who undergo partial nephrectomy and ablation. In addition, CT or MR imaging is useful in the routine postoperative surveillance for recurrent neoplasm or metachronous lesions.
In this talk, we discuss major role of imaging in
detection and staging of RCC or recurrence after treatment.
