Correlation of abdominal CT imaging with autopsy findings in patients with malignant tumors

Abstract

The value of abdominal computed tomography (CT) in diagnosing localized involvement of liver, pancreas, adrenals, and lymph nodes was evaluated in 117 patients with suspected or known malignant tumors by correlation with autopsy findings. Sensitivity, specificity, and accuracy of CT for localized liver disease was calculated to be 80% (84%), 96% (97%), and 90% (92%); for pancreatic tumors: 81% (86%), 98% (100%), and 95% (97%); for adrenal tumors: 65% (92%), 100% (100%), and 92% (98%); and for lymph node enlargement 75 (88%), 97% (98%), and 87% (94%), respectively. Results of routine evaluation could be improved, especially in the adrenal region, when scans were reevaluated by highly experienced examiners (results given in parenthesis). Computed tomography is a highly valuable diagnostic tool in the primary diagnosis and in the follow-up of tumor patients. The high costs are offset by a reduction in invasive procedures and a shortened hospital stay.
