The Value Of320-detector Row CT In Diagnosis Of Primary Cerebrovascular Hemorrhagic Disease

Intracranial hemorrhage caused by primary cerebrovascular bleeding disorders has deadlyoutcome. It is imperative for its early detection and diagnosis. Cerebral angiography was regardedas "gold standard" in diagnosis of vascular diseases. But its defects of being invasive, time-consuming restrict its application in patients with emergent medical condition. Similarly, static3D-CTA, MRA are also insufficient to reflect abnormal blood flow in real-time. Recent years, as therepresentative of dynamic CTA (4D-CTA),320-detector row CT has highlighted its potential valuein correct diagnosis of vascular disease. In this paper, we put intracranial aneurysm, brainarteriovenous malformations, intracranial dural arteriovenous fistula and moyamoya disease to runretrospective and comparative study with randomized and double-blind, based on image data fromthe cerebral angiography and4D-CTA in order to identify the value of4D-CTA in diagnosis ofacute cerebrovascular hemorrhagic disease and other assistant ability. Research results indicate that320-detector row CT has excellent ability in detecting characteristics of respective vascularstructures in these four diseases with satisfactory sensitivity and accuracy. It is a method withminimally invasion, efficiency, safety and convenience. Meanwhile, it has more advantages inirritable and pediatric patients to cerebral angiography and enables to guide the following treatmentand making operative strategy. However, under current technical conditions, the spatial andtemporal resolutions of320-detector row CT still inferior to cerebral angiography. Its ability ofdiscernment of the tiny vascular structures is still insufficient. And its nature of being non-selectivecannot be overcome. These shortcomings restrict it to make an adequate substitute for cerebralangiography as a preferred diagnosis in cerebrovascular disease. It still needs further and largerinvestigations.
