Coronary computed tomography angiography [PDF]
Canadian Medical Association Journal, 2015 Contrast medium is injected intravenously, and multidetector technology is used to take an image of the heart during a single breath hold (acquisition time ~8 s for 64 detectors). Blockade is recommended for patients with heart rates faster than 65 beats/min to improve image quality and to ...

Coronary computed tomography angiography in children [PDF]
Pediatric Radiology, 2021 Imaging the coronary arteries of children, with their faster heart rates, small vessel size and common inability to lie still or breath-hold, has been a major challenge. With numerous advances in technology, CT examinations can now be performed quickly, often with children free-breathing and with much lower radiation doses than previously. This has led

“Distal bright vessel sign” – Novel radiological sign of pulmonary thromboembolism
Radiology Case Reports, 2020 We describe a novel radiological sign of pulmonary thromboembolism on computed tomography aortic angiogram. It consists of focal hyperenhancement of pulmonary arteries distal to the pulmonary thrombus, while the thrombus itself remains occult and the ...

Lokelma's Interaction With Computed Tomography Angiography
Annals of Internal Medicine: Clinical Cases, 2023 A hospitalized 58-year-old man with hyperkalemia received oral Lokelma. Computed tomography angiography was performed due to concern for gastrointestinal (GI) bleeding, which demonstrated radiopaque material throughout the GI tract, even though no oral ...

Acute Pulmonary Embolism: Prognostic Role of Computed Tomography Pulmonary Angiography (CTPA)
Tomography, 2022 Computed Tomography Pulmonary Angiography (CTPA) is considered the gold standard diagnostic technique in patients with suspected acute pulmonary embolism in emergency departments. Several studies have been conducted on the predictive value of CTPA on the
