Adjustable computerized stereotaxic brain atlas for transmission and emission tomography.
A computerized brain atlas adjustable to the patient's anatomy would serve serveral purposes. It could be used in stereotaxic surgery. Even more important would be its use in medical imaging to identify various brain structures, such as the basal ganglia and their nuclei, as well as individual cortical gyri. This atlas could be used for additional mapping of nonvisible structures in images obta...
متن کاملAbnormal cerebral blood flow in methamphetamine abusers assessed by brain perfusion single emission computed tomography
Introduction:Amphetamines are central nervous system (CNS) stimulant substances and amphetamine abuse is considered a growing problem in our country. Previous studies revealed destructive effects of amphetamines on metabolism, perfusion and structure of brain. The aim of current study was evaluating regional cerebral blood flow (rCBF) disturbances in methamphetamine (MA) abuser...
متن کاملPositron emission tomography for brain research.
Positron emission tomography (PET) is a nuclear medicine imaging technique. Through the use of various radiopharmaceuticals, PET allows in vivo imaging of regional cerebral functions, including cerebral blood flow, molecular metabolism, and receptor binding capacity. PET is useful not only for diagnosis and therapeutic planning but also for neurological science research.
متن کاملComparison between emission and transmission computed tomography of the liver.
Emission computed tomography (emission CT) and conventional planar gamma-camera imaging of the liver were compared in 242 patients with suspected metastatic spread to liver. Concordant data were obtained in 171 patients (71%). Single large lesions, multiple small lesions, and diffuse disease were accurately defined with this new radionuclide tomographic technique. The smallest lesion detected b...
متن کاملDescription of a prototype emission-transmission computed tomography imaging system.
We have developed a prototype imaging system that can perform simultaneous x-ray transmission CT and SPECT phantom studies. This system employs a 23-element high-purity-germanium detector array. The detector array is coupled to a collimator with septa angled toward the focal spot of an x-ray tube. During image acquisition, the x-ray fan beam and the detector array move synchronously along an ar...
