Computer-Aided Diagnosis in Computed Tomographic Colonography

  • Kenji Suzuki
  • Abraham H. Dachman


Computed tomographic colonography (CTC) is gaining acceptance as a method to screen the colon and rectum for polyps and masses, but there is a substantial learning curve [1, 2] and sensitivity remains variable [3]. Computer-aided diagnosis (CAD) has recently been referred to more often as “computer aided detection” and abbreviated CADe as distinct from CADx, which refers to features which differentiate benign from malignant lesions. CADe reflects the fact that the software is not making any histologically specific feature analyses, but only looking for polyp candidates. In this chapter the generic term “CAD” will be used with the understanding that it refers to CADe.
