Computer-aided diagnosis in chest radiography
We have developed computer-aided diagnosis (CAD) schemes for the detection of lung nodules, interstitial lung diseases, interval changes, and asymmetric opacities, and also for the differential diagnosis of lung nodules and interstitial lung diseases on chest radiographs. Observer performance studies indicate clearly that radiologists' diagnostic accuracy was improved significantly when radiolo...
متن کاملBreast MRI and Computer Aided Diagnosis
Recently, there has been rapid increase per year in the number of breast MR studies performed in Korea. Dynamic contrast enhanced magnetic resonance mammography is a well-established method in the diagnosis of invasive breast cancer with a sensitivity near 100%. Distinction between benign and malignant lesions in MRI is possible by evaluating their morphology and enhancement pattern. A strong i...
متن کاملA Computer-Aided Diagnosis for Evaluating Lung Nodules on Chest CT: the Current Status and Perspective
As the detection and characterization of lung nodules are of paramount importance in thoracic radiology, various tools for making a computer-aided diagnosis (CAD) have been developed to improve the diagnostic performance of radiologists in clinical practice. Numerous studies over the years have shown that the CAD system can effectively help readers identify more nodules. Moreover, nodule malign...
متن کاملLearning techniques for Computer Aided Diagnosis in Chest Radiography
Radiologists can miss up to 30% of lung nodules (which may develop into cancer) in chest radiographs due to the background anatomy of the lungs which can camouflage the nodules. CAD helps radiologists by performing preprocessing of the images and suggesting the most likely locations for nodules. Detection of lung nodules proceeds through techniques for suppressing the background structures in l...
متن کاملPulmonary 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...
