An intravenous isotope method for measuring regional cerebral blood flow (rCBF) and volume (rCBV)

Abstract
The regional cerebral blood flow (rCBF), initial slope index (ISI), transfer time (.hivin.th) and volume (rCBV) were measured simultaneously in 43 hospital patients using a 133Xe i.v. injection method and quantitative dynamic 99mTc brain scintigraphy. The measurements were made with a gamma camera, and the data processing interfaced with a small digital computer.
