BACKGROUND AND PURPOSE: Clinicians are insecure reading CT scans by using the
one-third rule for acute middle cerebral artery stroke (1/3 MCA rule) before treating patients with …

Background and Purpose— There is ongoing controversy about the impact of hemorrhagic
transformation after thrombolysis on long-term functional outcome. We sought to study the …

Background and Purpose— The Alberta Stroke Program Early CT Score (ASPECTS) is a
grading system to assess ischemic changes on CT in acute ischemic stroke. CT angiography–…

Background and Purpose—The hyperdense appearance of the main middle cerebral artery
(HMCA) is now a familiar early warning of large cerebral infarction, brain edema, and poor …

✓ In a pilot study, two groups of patients with malignant glioma underwent sequential
neuropsychological evaluations after successful tumor treatment. Group 1 included nine patients …

The authors measured the association of early ischemic change on CT scan, measured using
the Alberta Stroke Programme Early CT score (ASPECTS), and functional outcome in 825 …

OBJECTIVE: To determine whether the rate of detecting a tumour, arteriovenous malformation
(AVM) or aneurysm with the use of enhanced or unenhanced computed tomography (CT) …

Contrast enhancement resulting from surgical trauma may mimic residual enhancing tumor,
thereby complicating the interpretation of postoperative computed tomographic scans. We …

Background: acute ischaemic stroke is common in older people. There is one licensed acute
treatment, intravenous recombinant tissue plasminogen activator, but little information is …

Objectives: In this study we define the probability of vascular abnormality in the middle cerebral
artery (MCA) territory according to the extent of ischaemic change seen using computed …
