99mTc-Sulfur colloid single photon emission computed tomography for assessment of liver function

Monte Carlo Study of the Effect of Backscatter Materail Thickness on 99mTc Source Response in Single Photon Emission Computed Tomography

Introduction SPECT projections are contaminated by scatter radiation, resulting in reduced image contrast and quantitative errors. Backscatter constitutes a major part of the scatter contamination in lower energy windows. The current study is an evaluation of the effect of backscatter material on FWHM and image quality investigated by Monte Carlo simulation. Materials and Methods SIMIND program...

Single Photon Emission Computed Tomography

[Single-photon emission computed tomography for the assessment of ventricular perfusion and function].

BACKGROUND Single-photon emission computed tomography (SPECT) can be used as a non-invasive tool for the assessment of coronary perfusion. AIM To assess ventricular perfusion and function by SPECT in patients with single vessel coronary artery disease. MATERIAL AND METHODS Among patients with indications for a coronary artery angiography, those with significant lesions in one vessel, were s...

Positron emission tomography and single photon emission computed tomography.

Neuroimaging techniques have had a dramatic impact on the evaluation and treatment of patients with epilepsy. In order to take full advantage of their potential, it is important to place them in clinical and electrophysiological context and to understand their technical limitations. Positron emission tomography with 18F-2-deoxyglucose and single photon emission computed tomography can provide v...
