Overview
Brief Summary
RATIONALE: New diagnostic procedures such as computed tomographic colonography may provide a less invasive method of identifying patients who have colorectal neoplasia.
PURPOSE: Diagnostic study to compare the effectiveness of computerized tomographic colonography with that of standard diagnostic procedures in detecting colorectal neoplasia.
Detailed Description
OBJECTIVES: I. Compare retrospectively the accuracy of computerized tomographic colonography (CTC) vs pathology and colonoscopy in the detection of clinically important colorectal neoplasia, defined as at least one proven lesion with a diameter measuring at least 1 cm. II. Compare the physician image display preferences and interpretation time across three viewing platforms for CTC images. OUTLINE: This is a retrospective, multicenter study. Radiologists evaluate each patient's optimal diagnostic computerized tomographic colonography (CTC) data. Patients' CTC findings are evaluated by a radiologist at a central facility using an imaging display software platform from General Electric, Vital Images, or the Mayo Clinic. CTC findings are compared with conventional colonoscopy findings and pathologic analysis. A comparison is made between physician image display preferences and interpretation time across three viewing platforms for CTC images. PROJECTED ACCRUAL: A total of 90 patients will be accrued for this study.
