Selective and divided visual attention: age-related changes in regional cerebral blood flow measured by H2(15)O PET

Autor: D J, Madden, T G, Turkington, J M, Provenzale, T C, Hawk, J M, Hoffman, R E, Coleman

Publikováno v: Human brain mapping. 5(6)

Regional cerebral blood flow (rCBF) was measured using H2(15)O and positron emission tomography (PET) to test the hypothesis that age-related changes in the pattern of rCBF activation would be greater under divided attention conditions than under sel

PET Scanner Quality Control

Autor: T.-G. Turkington

Publikováno v: PET and PET-CT in Oncology ISBN: 9783642622984

The quality control (QC) related to PET instruments includes specific procedures that are performed on the systems, monitoring of the routine data acquisition process, and inspection of the data produced by the system. As with all QC, a limited amoun

Introduction to PET instrumentation

Autor: T G, Turkington

Publikováno v: Journal of nuclear medicine technology. 29(1)

The purpose of this paper is to introduce technologists to the basic principles of PET imaging and to the instrumentation used to acquire PET data. PET imaging is currently being done on a variety of imaging system types, and the technologist will be

Measuring astatine-211 distributions with SPECT

Autor: T G, Turkington, M R, Zalutsky, R J, Jaszczak, P K, Garg, G, Vaidyanathan, R E, Coleman

Publikováno v: Physics in medicine and biology. 38(8)

We have investigated standard SPECT techniques (rotating gamma cameras, multi-hole collimators, and filtered backprojection reconstruction) for imaging astatine-211 distributions. Since 211At emits alpha particles, this nuclide has potential for use
