Automatic centerline extraction of coronary arteries in coronary computed tomographic angiography

Computed tomographic imaging of anomalous coronary arteries.

Coronary Arteries To the Editor: Ropers et al1 present a series of images demonstrating that the proximal course of anomalous left main and left anterior descending coronary arteries originating from the right sinus of Valsalva can be visualized by electron beam computed tomography. We are writing to communicate that more widely available, retrospectively gated multislice computed tomography (M...

Anomalous coronary arteries: depiction at dual-source computed tomographic coronary angiography.

OBJECTIVE To retrospectively determine the imaging features of coronary artery anomalies depicted at dual-source computed tomographic coronary angiography (DSCT-CA). METHODS We reviewed the case histories of 12,145 patients with suspected coronary arterial disease who underwent DSCT-CA at our institution. Multiplanar reformation, maximum-intensity projection, and volume-rendered imaging were ...

Model-Driven Centerline Extraction for Severely Occluded Major Coronary Arteries

Almost all previous approaches on coronary artery centerline extraction are data-driven, which try to trace a centerline from an automatically detected or manually specified coronary ostium. No or little high level prior information is used; therefore, the centerline tracing procedure may terminate early at a severe occlusion or an anatomically inconsistent centerline course may be generated. I...

Diagnostic accuracy and impact of computed tomographic coronary angiography on utilization of invasive coronary angiography.

BACKGROUND Computed tomographic coronary angiography (CTA), given its high negative predictive value, is a potential gatekeeper for invasive coronary angiography (ICA). Before CTA can be further accepted into clinical practice, its impact on healthcare resources needs to be better understood. We sought to determine the clinical impact of CTA on ICA referrals, CTA accuracy, and normalcy rate. ...
