Computed Tomography Angiography

2020
Computed tomography angiography (CTA) provides additive information to conventional CT in neuroradiology. It visualizes vascular structures after intravascular injection of a radiopaque contrast material. With the introduction of multi-detector-row spiral CT, CTA has become the standard technique for fast and accurate vascular imaging.

Flat-panel detector CT assessment in stroke to reduce times to intra-arterial treatment: A study of multiphase computed tomography angiography in the angiography suite to bypass conventional imaging

International Journal of Stroke, 2020
Background Bypassing the emergency department and the computed tomography suite by directly transporting to the neuroangiography suite for imaging assessment and treatment may shorten reperfusion times while maintaining proper patient selection ...

Postmortem Computed Tomography and Computed Tomography Angiography

Journal of Thoracic Imaging, 2019
With the introduction of modern imaging technology into the forensic field, postmortem imaging, particularly postmortem computed tomography (PMCT), has gained increasing importance in forensic investigations of deaths. In recent years, PMCT, which aims to provide observer-independent, reproducible forensic assessment in a minimally invasive manner, has

Computed Tomography Angiography (CTA)

2019
Multidetector CTA (MDCTA) of the peripheral arteries has high accuracy for detection of steno-occlusive diseases when compared with DSA. Its advantages over DSA include minimal invasiveness, reduced volume of contrast material, shorter scan times, and fast data acquisition.

Postmortem-computed tomography and postmortem-computed tomography–angiography: a focused update

La radiologia medica, 2015
The use of multidetector CT (MDCT) represents a reality routinely used in several forensic institutes, for the numerous advantages that this diagnostic tool can provide; costs are becoming increasingly lower; data acquisition is always faster and once acquired may be revalued at any time. However, there are also some diagnostic limitations, for example,

Computed tomography imaging and angiography – principles

2016
The evaluation of patients with diverse neurologic disorders was forever changed in the summer of 1973, when the first commercial computed tomography (CT) scanners were introduced. Until then, the detection and characterization of intracranial or spinal lesions could only be inferred by limited spatial resolution radioisotope scans, or by the patterns ...
