Computed Tomographic Perfusion Improves Diagnostic Power of Coronary Computed Tomographic Angiography in Women

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 ...

Time-Resolved C-Arm Computed Tomographic Angiography Derived From Computed Tomographic Perfusion Acquisition

Patients with acute ischemic stroke (AIS), especially those because of a large vessel occlusion (LVO), have poor prognosis. Although intravenous tissue-type plasminogen activator has been shown to offer benefit in some patients with an AIS, its efficacy in those with LVOs is poor. The majority of the AIS patients with LVOs will die or have severe disability despite intravenous tissue-type plasm...

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.

Computed tomographic angiography in intracranial vascular diseases

Background. The development of spiral computed tomography (CT) introduced more precise imaging of the vessels also with computed tomographic angiography (CTA). Because it is minimaly invasive method, it was widely accepted by radiologists and clinicians. In early 90 ties CTA also accompanied conventional angiography and magnetic resonance angiography (MRA) in imaging of intracranial vascular di...
