ClearRead CT | Compare

ClearRead CT Compare extends Detect by automatically matching nodules found in a current exam to the same nodule in a prior exam, enabling efficient visual and volumetric comparisons. The image to the right includes the current exam on the left and the prior exam on the right. The image chips at the bottom provide a close-up view of the individual finding, along with extracted measurements.
