9.3.1.2 Computed Tomography

CT has an accuracy in CC ranging from 32% to 80%. Its sensitivity and specificity in the detection of parametrial invasion vary from 17% to 100%, with a mean of 64%, and 50% to 100%, with a mean of 81%, respectively. The consensus from the literature is that the value of CT is increased in the most advanced stages of the disease but that CT has limited value (a positive predictive value of 58%) in the evaluation of early parametrial invasion. CT has high accuracy in the detection of advanced disease. However, a recent study by ACRIN® reported that CT has a sensitivity of only 42% for the detection of advanced disease, with ranges of sensitivity and specificity for detecting parametrial invasion of 14–38% and 84–100%, respectively (Fig. 9.5) [10].
