COMPUTED TOMOGRAPHY ANGIOGRAPHY
Neuroimaging Clinics of North America, 1996Spiral computed tomography angiography is a relatively new noninvasive technique capable of rapid imaging of the carotid artery. Computed tomography angiography usually is performed in a 30-second scan time and images iodinated contrast as it fills the vascular lumen.

Computed Tomography Angiography
2020Computed 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.

Computed Tomography Angiography of the Upper Extremities
Radiologic Clinics of North America, 2016Upper extremity computed tomography angiography is a powerful tool in the evaluation of acute and nonacute arterial pathology. Technical principles including patient positioning, choice of contrast injection site and rate of administration, and physiologic considerations must be optimized to achieve a high-quality angiographic study.

Computer Tomography and Angiography in Renal Angiomyolipoma
Acta Radiologica. Diagnosis, 1981Computer tomography and nephroangiography were performed in 5 patients with angiomyolipoma of the kidneys. CT was characteristic in all cases by demonstrating areas of fat in the tumor, and the extent of the neoplasm could be assessed preoperatively. Nephroangiography was of value as a preoperative demonstration of the vascular anatomy.

Computed Tomography and Angiography in Hepatocellular Carcinoma
Acta Radiologica. Diagnosis, 1982Computed tomography and angiography were performed in 12 patients with hepatocellular carcinoma, all demonstrated with CT. In 11, the tumor had a lower attenuation than the liver parenchyma, in one a higher attenuation. Two patients had 2 lesions. The hepatic contour protruded in 10 patients.

Computed Tomography and Angiography of Hepatocellular Carcinoma
Journal of Computer Assisted Tomography, 1980Thirty patients with primary hepatocellular carcinoma were studied by computed tomography (CT) and angiography. Tumor images on CT could be classified into four groups according to the differences between precontrast and postcontrast scans. In comparing the findings of angiography and CT, hypervascular tumor shadows on angiography were visualized as ...

Computed Tomography Angiography of the Thoracic Aorta
Radiologic Clinics of North America, 2016This article reviews the multidetector-row computed tomography (MDCT) imaging appearance of common entities that are part of the wide spectrum of diseases involving the thoracic aorta. Electrocardiogram-gated MDCT is poised to become the reference standard method in assessing the thoracic aorta.

Postmortem-computed tomography and postmortem-computed tomography–angiography: a focused update
La radiologia medica, 2015The 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,

Postmortem Computed Tomography and Computed Tomography Angiography
Journal of Thoracic Imaging, 2019With 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 of the Lower Extremities
Radiologic Clinics of North America, 2016CT angiography (CTA) of the lower extremities is an important and versatile, noninvasive tool for diagnosis as well as surgical or endovascular interventional planning. Although lower extremity CTA is most commonly performed in patients with peripheral artery disease or trauma affecting the lower extremities, it also plays a role in the workup of ...
