Time-Resolved C-Arm Computed Tomographic Angiography Derived From Computed Tomographic Perfusion Acquisition
Patients with acute ischemic stroke (AIS), especially those because of a large vessel occlusion (LVO), have poor prognosis. Although intravenous tissue-type plasminogen activator has been shown to offer benefit in some patients with an AIS, its efficacy in those with LVOs is poor. The majority of the AIS patients with LVOs will die or have severe disability despite intravenous tissue-type plasm...
متن کاملUtility of Computed Tomographic Perfusion in Thrombolysis for Minor Stroke.
BACKGROUND AND PURPOSE The use of thrombolysis in acute minor ischemic stroke (MIS) remains controversial. We sought to determine the safety and efficacy of intravenous tissue-type plasminogen activator (IV-tPA) in acute MIS patients with demonstrable penumbra on computed tomographic perfusion study. METHODS Consecutive MIS patients with National Institutes of Health Stroke Scale ≤3 were iden...
متن کاملIncreasing use of computed tomographic perfusion and computed tomographic angiograms in acute ischemic stroke from 2006 to 2010.
BACKGROUND AND PURPOSE Our objective was to study nationwide utilization trends of computed tomographic (CT) angiogram (CTA) and CT perfusion (CTP) in acute ischemic stroke and particularly in the context of use of reperfusion therapies. METHODS We reviewed the Premier Perspective Database for ischemic stroke-related hospitalizations of adult patients during a 5-year period, 2006 to 2010. Use...
متن کاملComputed Tomographic measurement of distal femor rotation in Iranian population
Background: Proper rotation of components in total knee arthroplasty (TKA) will largely affect the postoperative outcome. Ethnical variation may affect rotational profile. We aimed to evaluate distal femur rotation in Iranian population using transepicondylar axes. Methods : From a total of 450 knee CT scans and via consecutive sampling, 150 qualified subjects with normal lower extremities ...
متن کاملCranial Computed Tomographic Abnormalities
Sixty-four (57.6%) of 111 cancer patients with cerebrospinal fluid cytology positive for malignant cells had cranial computed tomographic (CT) scans within 2 weeks before or after a lumbar puncture. Twenty-two (34.3%) of the 64 had abnormal CT findings indicative of leptomeningeal metastasis: (1) sulcal-cisternal enhancement, (2) ependymal-subependymal enhancement, (3) widened irregular tentori...
