Safety of intravenous β-adrenoceptor blockers for computed tomographic coronary angiography

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 ...

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.

Coronary computed tomographic angiography and incidental pulmonary nodules.

I ncidental findings are an important topic in diagnostic imaging. Because of the comprehensive nature of computed tomography (CT) scanning, incidental findings are seemingly found on almost every CT scan performed for a wide variety of reasons in a radiology department. Many of these incidental findings such as a liver cyst are benign and immediately dismissed. Other findings require more exte...
