To develop non-invasive regional cerebral blood flow (rCBF) measurements using
technetium-99m ethyl cysteinate dimer ( 99m Tc-ECD) and single-photon emission tomography (…

The previously reported method for quantitative measurements of whole-brain or
hemispheric-brain perfusion using technetium-99m hexamethylpropylene amine oxime (HMPAO) …

A non-invasive, simple method for the quantitative evaluation of brain perfusion is presented
using intravenous radionuclide angiography with technetium-99m hexamethylpropylene …

Objective: To elucidate the radiation effect on the normal brain after stereotactic radiosurgery
(SRS), we evaluated the change in regional cerebral blood flow (CBF) in targeted and extra…

This is a report of a patient who underwent high-resolution brain perfusion SPECT studies
during and after an episode of transient global amnesia. During the attack, SPECT imaging …

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 …

A 69-year-old man had hypothyroid dementia as a result of I-131 therapy and an overdose
of methimazole. Tc-99m HMPAO SPECT revealed diffuse cerebral hypoperfusion. The …

Sympathetic nervous activation is a crucial compensatory mechanism in heart failure. However,
excess catecholamine may induce cardiac dysfunction and β-adrenergic desensitization…

Purpose Pulmonary ventilation and circulation dynamics are reflected on fluoroscopic
images as changes in X-ray translucency. The purpose of this study was to investigate the …

Background Cardiac 123 I-meta-iodobenzylguanidine (MIBG) uptake is quantified using the
heart-to-mediastinum ratio (HMR) with an Anger camera. The relationship between HMR …
