Quantitative Single-Photon Emission Computed Tomography/Computed Tomography for Glomerular Filtration Rate Measurement

Quantitative single-photon emission computed tomography imaging.

Over the past decade, quantitation of cardiac single-photon emission computed tomography (SPECT) data, once limited to perfusion assessment, has been extended to global and regional function assessment for both the left and the right ventricle, as well as to measurement of additional cardiac parameters of diagnostic and prognostic interest. A number of commercially available quantitative algori...

Quantitative single-photon emission computed tomography/computed tomography for technetium pertechnetate thyroid uptake measurement

OBJECTIVES Technetium pertechnetate (TcO4) is a radioactive tracer used to assess thyroid function by thyroid uptake system (TUS). However, the TUS often fails to deliver accurate measurements of the percent of thyroid uptake (%thyroid uptake) of TcO4. Here, we investigated the usefulness of quantitative single-photon emission computed tomography/computed tomography (SPECT/CT) after injection o...

Single Photon Emission Computed Tomography

Assessed by Quantitative Thallium-201 Single-Photon Emission Computed Tomography

The extent of abnormally perfused myocardium was compared in patients with and without chest pain during treadmill exercise from a large, relatively low-risk consecutive patient population (n=356) referred for quantitative thallium-201 single-photon emission computed tomography (SPECT). All patients had concurrent coronary angiography. Patients were excluded if they had prior coronary angioplas...

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...
