Pulmonary nodules at chest CT: effect of computer-aided diagnosis on radiologists' detection performance.
PURPOSE To evaluate the effect of computer-aided diagnosis (CAD) on radiologists' detection of pulmonary nodules. MATERIALS AND METHODS Fifty chest computed tomographic (CT) examination cases were used. The mean nodule size was 0.81 cm +/- 0.60 (SD) (range, 0.3-2.9 cm). Alternative free-response receiver operating characteristic (ROC) analysis with a continuous rating scale was used to compar...
متن کاملComputer-aided detection in screening CT for pulmonary nodules.
OBJECTIVE Our objective was to evaluate the performance of a computer-aided detection (CAD) system for pulmonary nodule detection using low-dose screening CT images. MATERIALS AND METHODS One hundred fifty consecutive low-dose screening CT examinations were independently evaluated by a radiologist and a CAD pulmonary nodule detection system (R2 Technology) designed to identify nodules larger ...
متن کاملA comparative study for 2D and 3D computer-aided diagnosis methods for solitary pulmonary nodules
Many computer-aided diagnosis (CAD) methods, including 2D and 3D approaches, have been proposed for solitary pulmonary nodules (SPNs). However, the detection and diagnosis of SPNs remain challenging in many clinical circumstances. One goal of this work is to investigate the relative diagnostic accuracy of 2D and 3D methods. An additional goal is to develop a two-stage approach that combines the...
متن کاملComputer Aided Diagnosis For the Detection of Lung Nodules
Lungs segmentation is a vital step for computer aided diagnosis. Many lungs diseases requiring radiological support for diagnostic purpose, including tuberculosis, emphysema and lungs cancer could be affectively diagnosed using computer-aid. Pulmonary nodules usually act as the early stage characterization of lung cancer. It’s a crucial way to control the disease and reduce the mortality by fur...
متن کاملComputer Aided Polyp Detection with Texture Analysis
We present a novel pipeline for computer-aided detection (CAD) of colonic polyps by integrating texture analysis with volume rendering and conformal colon flattening. Using our method, the 3D polyp automatic detection problem is converted into a 2D image analysis problem. The colon surface is first segmented and extracted from the CT data set of the abdomen, which is then mapped to a 2D rectang...
