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.

Computed tomography angiography for the interventional cardiologist

European Heart Journal - Cardiovascular Imaging, 2014
In recent years, coronary CT angiography (CCTA) has become a widely adopted technique, not only due to its high diagnostic accuracy, but also to the fact that CCTA provides a comprehensive evaluation of the total (obstructive and non-obstructive) coronary atherosclerotic burden.

Computer Tomography and Angiography in Renal Angiomyolipoma

Acta Radiologica. Diagnosis, 1981
Computer 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 ANGIOGRAPHY

Neuroimaging Clinics of North America, 1996
Spiral 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 and Angiography in Hepatocellular Carcinoma

Acta Radiologica. Diagnosis, 1982
Computed 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 Angiography of the Extremities in Emergencies

Seminars in Ultrasound, CT and MRI, 2017
Computed tomography angiography (CTA) of the extremities offers a noninvasive, rapid means of evaluation of the extremities in vascular emergencies. CTA is now the first-line investigation for this purpose, offering high sensitivity and specificity in diagnosis.

Computed Tomography Angiography of the Upper Extremities

Radiologic Clinics of North America, 2016
Upper 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.

Computed Tomography Angiography of the Thoracic Aorta

Radiologic Clinics of North America, 2016
This 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.

Computed Tomography and Angiography of Hepatocellular Carcinoma

Journal of Computer Assisted Tomography, 1980
Thirty 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 ...
