COMPUTER AIDED DETECTION & QUANTIFICATIONand Results with Respect to Pulmonary Nodules in High Resolution CT Data

With the superb spatial resolution of modern multi-slice CT scanners and their ability to complete a high resolution thoracic scan within one breath hold, software algorithms for computer aided detection (CAD) of pulmonary nodules are now reaching high sensitivity levels at moderate false positive rates. Pilot studies indicate that CAD software modules can serve as a powerful tool for diagnostic quality assurance. Equally important are tools for fast and accurate automatic three-dimensional volume measurement of detected nodules. Computer aided diagnosis (CADx) tools such as automated three-dimensional quantification of contrast enhancement in dynamic CT help to exclude benign nodules and reduce biopsies.
