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...
متن کاملComputed tomographic angiography coming of age.
C tomographic angiography (CTA) of the coronary arteries is in its relative infancy. Newergeneration electron beam computed tomography and the rapid development of multidetector ( 64 slices) computed tomography (MDCT) with increased spatial resolution (0.33 mm) and temporal resolution (50 to 100 ms with multisegment reconstruction), shorter breathhold (5 to 12 seconds), and less contrast (60 to...

متن کاملTime-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...
متن کاملProjection-based bolus detection for computed tomographic angiography.
Computed tomographic (CT) angiography is important for imaging studies on cardiovascular structures, peripheral vessels, and solid organs. In practice, a CT angiography scan is triggered by the bolus arrival at a prespecified anatomical location, which is determined using CT fluoroscopy. In this article, we propose a projection-based method adapted from the Grangeat formula to detect the bolus ...
