Figure 1 The graph shows the calculated sensitivities for the 3 computer-aided detection algorithms for the detection of all polyps plotted over the number of false-positive findings. SL = sphericity level of system 1; CL = confidence level of system 2.

Figure 2 The graph shows the calculated sensitivities for the 3 computer-aided detection algorithms for the detection of polyps ≥10 mm plotted over the number of false-positive findings. SL = sphericity level; CL = confidence level.

Figure 3 Axial image of a CTC data set in supine-position, illustrating the successful computer-aided detection of a polyp, despite overlying residual opacified fluid in the colon. The sessile polyp detected in a 66-year-old patient with chronic abdominal discomfort was detected by all 3 computer-aided detection systems.

Figure 4 A typical false-positive result within the computer-aided detection analysis because of residual feces that mimicked a polyp, illustrated in an axial reconstruction of the computed tomographic colonography data with the patient in the supine position. The false-positive finding was observed after computer-aided detection analysis with system 1.
