Attenuation map segmentation in low-dose PET/CT
Autor: R L Eisner, Jonathon A. Nye, James J. Hamill, Bing Bai, M Ichise
Publikováno v: IEEE Nuclear Science Symposuim & Medical Imaging Conference.
In PET/CT studies, artifacts can occur in CT/AC scans when parameters are adjusted to reduce CT radiation exposure to very low levels, and these can in turn cause PET errors. Scanning at 80 kVp instead of 120 or 130 kVp can result in attenuation corr

Attenuation artifacts in SPECT: effect of wrap-around lung in 180 degrees cardiac studies
Autor: E V, Di Bella, R L, Eisner, A B, Barclay, R E, Patterson, D J, Nowak
Publikováno v: Journal of nuclear medicine : official publication, Society of Nuclear Medicine. 37(11)
We estimated that in 75%-90% of PET 82Rb patients the left lung appeared to wrap around the anterior aspect of the left ventricle. We used clinical PET 82Rb myocardial perfusion studies as the input to a SPECT computer simulation model to determine i

Diagnosis of coronary artery disease in women: roles of three dimensional imaging with magnetic resonance or positron emission tomography
Autor: R E, Patterson, K B, Churchwell, R L, Eisner
Publikováno v: American journal of cardiac imaging. 10(1)
Diagnosis and assessment of coronary artery disease (CAD) is especially difficult in women. The history of chest discomfort and various noninvasive tests each have particular problems, which indicate the need to consider more accurate tests such as c

Defects on SPECT 'perfusion' images can occur due to abnormal segmental contraction
Autor: R L, Eisner, L S, Schmarkey, S E, Martin, D, Carey, M A, Worthy, T H, Chu, S F, Horowitz, R E, Patterson
Publikováno v: Journal of nuclear medicine : official publication, Society of Nuclear Medicine. 35(4)
Technetium-99m-sestamibi images reflect tracer distribution at the time of injection. This "stay put" indicator allowed us to separate the effects of segmental left ventricular dysfunction per se versus myocardial blood flow on SPECT "perfusion" imag

Inhomogeneity of gated and ungated SPECT technetium-99m-sestamibi bull's-eyes in normal dogs: comparison with thallium-201
Autor: R L, Eisner, S E, Martin, A R, Leon, L S, Schmarkey, M A, Worthy, T H, Chu, R E, Patterson
Publikováno v: Journal of nuclear medicine : official publication, Society of Nuclear Medicine. 34(2)
By computer simulation, we have previously hypothesized, independent of the isotope imaged, that differences in view-to-view resolution and attenuation patterns predictably cause count density distortions in SPECT images. We tested the simulation pre
