Computer Aided Diagnosis-Basics

  • Computer-aided diagnosis  is rapidly entering the radiology mainstream. In developed conuntries, it has already become a part of the routine clinical work for mammograms. The computer output is used as a "second opinion" in assisting radiologists' image interpretations. 
  • The computer algorithm generally consists of several steps that may include image processing, image feature analysis, and data classification via the use of tools such as artificial neural networks (ANN).
  • It has also been used for lung nodules detection, vertebral fracture assessment and for evaluating serial interval changes. Detection of polyps in colon is another use and there is a role in nuclear scans. 
  • At the present stage of the technology, CAD cannot and may not substitute the doctor, but rather plays a supporting role.
