Abstract Objectives: Iodine-123 (123 I)-labeled N-isopropyl-p-iodoamphetamine (IMP) has
been used as a cerebral blood flow (CBF) tracer for single-photon emission computed …

The purpose of this study was to verify the feasibility and usefulness of a new SPECT
method, called triple injection of 99mTc-ethylcysteinate dimer (TIE), in evaluation of the …

Insufficiency of collateral supply may lead to low-flow infarcts in severe occlusive
cerebrovascular disease. The aim of this study was to evaluate the feasibility of technetium …

For semiquantification of SPECT studies we tried to calculate cerebral 99m Tc-HMPAO
uptake related to injected dose and estimated brain volume. The method was applied to …

This report describes a new approach to the evaluation of brain perfusion reserve using Tc-
99m HMPAO SPECT. Consecutive brain Tc-99m HMPAO SPECT studies before and after …

Sixty-five patients rferred for Tc-99m HMPAO SPECT brain perfusion studies had
measurements of global Tc-99m HMPAO retention after injection at rest and after …

Our phantom studies indicate that the energy resolution (9.7% FWHM) of a new three-
headed single-photon tomograph (PRISM-3000) separates the distribution of 99mTc from …
