Deep-Learning Image Reconstruction in CCTA

Cardiac CT allows the assessment of the heart and of the coronary arteries by use of ionising radiation. Although radiation exposure was significantly reduced in recent years, further decrease in radiation exposure is limited by increased image noise and deterioration in image quality. Recent evidence suggests that further technological refinements with artificial intelligence allows improved post-processing of images with reduction of image noise. The present study aims at as...

Diagnostic Performance of Deep Learning for Angle Closre

Primary angle closure diseases (PACD) are commonly seen in Asia. In clinical practice, gonioscopy is the gold standard for angle width classification in PACD patietns. However, gonioscopy is a contact examination and needs a long learning curve. Anterior segment optical coherence tomography (AS-OCT) is a non-contact test which can obtain three dimensional images of the anterior segment within seconds. Therefore, we designed the study to verify if AS-OCT based deep learning algo...

Deep-learning Based Location of Spine CT

CT-guided epidural steroid injection (ESI) thrives among interventional radiologists. Although X-ray fluoroscopy still remains as the gold standard to guide ESI, CT guidance has the merits of accurate location of needle tip and relatively low radiation doses with intermittent mode. However, it is time-consuming for doctors to select the optimal plane for needle placement and manually segment spinal structures. The main of the study is to automatically identify the optimal plane...

Study in Subjects Suspected of Having CAD Undergoing VISIPAQUE-enhanced CCTA as Part of Their Routine Medical Care
