Time resolved computed tomography angiography in the evaluation of brain arteriovenous malformation: a feasibility studyKeywords: Time resolved computed tomography angiography, four dimensional computed tomography angiography, arteriovenous malformation, 4D-CTA, TR-CTA, AVM Abstract: Digital subtraction angiography is the current gold standard for diagnosing as well as the follow-up of cerebral arteriovenous malformations. However, as it is invasive, relatively expensive and time-consuming, a non-invasive alternative is of interest. We aimed to evaluate the feasibility of time resolved computed tomography angiography (TR-CTA) in a series of five diagnosed cranial arteriovenous malformation patients, demonstrated by conventional digital subtraction angiography with respect to acquisition, depiction of angiographic phases and radiation exposure
