Brain imaging is performed using radiopharmaceuticals by single photon emission
computed tomography (SPECT) and positron emission tomography (PET). SPECT and PET …

Radiolabeled tracers allow visualization of not only perfusion, but receptors, function, and
metabolism as well. Although spatial resolution is lower than that of computed tomography …

BACKGROUND AND PURPOSE: Arterial spin-labeling is an emerging technique for
noninvasive measurement of cerebral perfusion, but concerns remain regarding the …

Recently, two methods have been proposed for regional cerebral blood flow (rCBF)
quantitation using [123I] iodoamphetamine (IMP) and single-photon emission computed …

A method has been developed to quantitate regional cerebral blood blow (rCBF) using
iodine-123-labelled N-isopropyl-p-iodoamphetamine (IMP). This technique requires only …

BACKGROUND AND PURPOSE: Crossed cerebellar diaschisis, not only a secondary result
of supratentorial infarction but also an indicator of clinical outcomes, has frequently been …

The regional distribution of I-123 iofetamine (IMP) in the brain of 12 patients with rapid
cycling bipolar disorder was studied by single-photon computed emission tomography …

Peri-ictal single-photon emission computed tomography (SPECT) of the brain is increasingly
used in localizing the seizure focus in presurgical evaluation of patients with partial epilepsy …

BACKGROUND AND PURPOSE: Cerebral hyperperfusion syndrome is a potential
complication of superficial temporal artery–MCA anastomosis for Moyamoya disease. In this …

BACKGROUND AND PURPOSE: Flow-sensitive alternating inversion recovery (FAIR) MR
imaging is a technique for depicting cerebral perfusion without contrast enhancement. Our …
