Coronary computed tomography angiography

Current Opinion in Cardiology, 2011
Significant limitations exist for traditional noninvasive cardiac imaging with regard to equivocal or indeterminate findings that result in repetitive testing or unnecessary referral to invasive coronary angiography (ICA). Recent hardware and software advances in multislice computed tomography angiography have achieved high spatial and temporal ...

Emergent CT angiography and risk of contrast-induced acute kidney injury in acute ischaemic stroke

Aktualności Neurologiczne, 2016
Objectives: Emergent computed tomography angiography with contrast is commonly performed for acute ischaemic stroke, but potentially delayed pending admission renal function assessment due to purported risk of contrast-induced acute kidney injury.

Utility of four-dimensional computed tomography angiography for evaluating the mobility of a thrombus in the ascending aorta

Radiology Case Reports, 2020
Four-dimensional computed tomography has been used to evaluate moving structures and is a useful method to diagnose cardiovascular diseases. We report a case of cerebral infarction due to the thrombus in the ascending aorta, and utilized 4-dimensional ...

Successful management of retropharyngeal hematoma by trans-arterial embolism without intubation

International Journal of Emergency Medicine, 2021
Background Retropharyngeal hematoma can cause suffocation if there is delay in securing the airway by intubation. However, there are also concerns about complications that can arise with intubation; it is still unknown which cases do not require ...

Massive hemoptysis treated with embolization of an ectopic bronchial artery arising from the right thyrocervical trunk: a case report

CVIR Endovascular, 2022
Background Ectopic bronchial artery and non-bronchial systemic arteries may be the culprit vessels of hemoptysis. The main cause of clinical failure of bronchial artery embolization is incomplete embolization caused by the misidentification of the ...

Role of noncontrast magnetic resonance pulmonary imaging in diagnosis of pulmonary embolism

Egyptian Journal of Chest Disease and Tuberculosis, 2022
Background Pulmonary embolism (PE) is a serious condition and has a clinical dilemma in diagnosis. Computed tomography pulmonary angiography (CTPA) is a gold standard in its diagnosis, but MRI has proven a good role in PE diagnosis.
