Automatic Identification 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 ...

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. ...

Coronary computed tomographic angiography: its role in emergency department triage.

Anatomy of an emerging diagnostic test: computed tomographic coronary angiography.

The study by Mollet et al on CT coronary angiography in this issue of Circulation is important for several reasons.1 The 64-multislice technology for acquiring tomographic x-rays of the coronary vessels during the arterial phase of a bolus of iodinated contrast introduces several technical advances: improved spatial resolution (thinner slices), improved temporal resolution (less time needed to ...
