Low-field magnetic resonance angiography in brain – vascular diseases. An option in hospitals without angiography
Keywords:
stroke, magnetic resonance angiography, intracranial aneurysmAbstract
A descriptive cross-sectional, descriptive, observational study was performed to evaluate a diagnostic, in this case a brain angioresonance, to 50 patients with cerebrovascular diseases and were treated at the Radiology Department of "Arnaldo Milian Castro" Hospital of Santa Clara City in the period between January 2010 and August 2012; the angioresonance was performed to all of them, validated by angiotomography and angiography by digital subtraction. The largest number of patients ranged in age between 41 and 60 years; with a prevalence of angioresonances performed in patients with hemorrhagic stroke relative to ischemic; subarachnoid hemorrhage was the principal diagnosis in the emergency of the on-line axial tomography; sequences and techniques more used were, with angioresonance, the suppression sequence of cerebrospinal fluid and T2 technique; the phase of flight time of arterial prevailed to respect to venous; the aneurysm was more vascular malformation diagnosed with moderate sensitivity and low specificity when compared with other techniques, which did not work well in the diagnosis of arteriovenous malformations which shows high sensitivity and specificity; in cerebral ischemia similar results were observed, especially for the study of intracranial vessels and were the time of flight and third axial dimension the sequences most useful.
