Reproducibility of measurements of cerebral infarct volume on CT scans.
BACKGROUND AND PURPOSE Infarct volume is increasingly used as an outcome measure in clinical trials of therapies for acute ischemic stroke. We tested which of 5 different methods to measure infarct size or volume on CT scans has the highest reproducibility. METHODS Infarct volume and total intracranial volume were measured with Leica Q500 MCP image analysis software, or with a caliper, on 38 ...
متن کاملCerebral blood flow is the optimal CT perfusion parameter for assessing infarct core.
BACKGROUND AND PURPOSE CT perfusion (CTP) is widely and rapidly accessible for imaging acute ischemic stroke but has limited validation. Cerebral blood volume (CBV) has been proposed as the best predictor of infarct core. We tested CBV against other common CTP parameters using contemporaneous diffusion MRI. METHODS Patients with acute ischemic stroke<6 hours after onset had CTP and diffusion ...
متن کاملCerebral schistosomiasis: MR and CT appearance.
After returning from Africa, a 54-year-old man began to have episodes of headache and nausea, then a cerebral convulsion. Clinical and laboratory findings and response to chemotherapy indicated the diagnosis of cerebral schistosomiasis. Three lesions were seen on CT and MR studies: two appeared to be subacute intracerebral hematomas, one in the right parietal lobe and one in the frontal lobe; t...
متن کاملOptimal technique aids cerebral perfusion CT
Thrombolytic therapy can restore normal blood flow in obstructed vessels following stroke, but treatment must be administered rapidly after onset of symptoms. Efforts have therefore been made to select and study which patients may benefit from this approach. A patient with suspected ischemic stroke first undergoes a basal unenhanced brain CT to evaluate the possible presence of hemorrhagic stro...
متن کاملDoes a relative perfusion measure predict cerebral infarct size?
BACKGROUND AND PURPOSE MR perfusion-weighted imaging (PWI) has been extensively used to quantify cerebral perfusion deficits after the onset of focal ischemia. The present study tested whether a relative measure of cerebral blood flow such as is obtained with PWI is sufficient to predict irreversible tissue damage following focal cerebral ischemia and reperfusion in the rat suture model. METH...
