Regional Arm-Brain Mean Transit Time In the Diagnostic Evaluation of Patients With Cerebral Vascular Disease
ثبت نشده
چکیده
By analyzing time-activity curves over selected brain regions, following intravenous administration of a non-diffusible radionuclide, it is possible to assess regional arm-brain mean transit time (rABmtT). By evaluating this parameter in normal subjects a relatively small range of differences between symmetrical regions can be found (030 ± 0.14 sec, mean ± SD). An increase of this difference above statistical limits was found in 82 % of patients with acute complete stroke, in 56 % of patients with chronic complete stroke and in 21 % of patients with transient iscbemic attacks.

Regional arm-brain mean transit time in the diagnostic evaluation of patients with cerebral vascular disease.
By analyzing time-activity curves over selected brain regions, following intravenous administration of non-diffusible radionuclide, it is possible to assess regional arm-brain mean transit time (rABmtT). By evaluating this parameter in normal subjects a relatively small range of differences between asymmetrical regions can be found (0.30 +/- 0.14 sec, mean +/- SD). An increase of this differenc...

Interrelationships Among Regional Cerebral Blood Flow, Mean Transit Time, Vascular Volume and Cerebral Vascular Resistance • The simultaneous measurement of regional cerebral blood flow (rCBF), mean transit time (MTT), vascular volume (CVV) and cerebral vascular resistance (CVR) was performed in patients with cerebrovascular diseases. The measurement was made by a gamma-ray scintillation camera...
