In the present study we have compared the implemen tation of partial volume correction by
the tissue fraction technique with an alternative independent method that requires the …

This study assesses the utility of a scintigraphic, nongeometric technique for the
determination of left ventricular volumes. Accordingly, gated blood pool scintigraphy and …

An in vivo technique was developed for measuring the absolute myocardial blood flow with
H215O and dynamic positron-emission tomography. This technique was based on a new …

The purpose of the study is to describe a method for the investigation of myocardial kinetics
(wall motion or wall thickening) to define myocardial perfusion characteristics further. The …

Background. Marked partial volume effects occur in myocardial single photon emission
computed tomographic (SPECT) studies because of limited resolution in imaging the …

Radionuclide measurements of left ventricular volume were determined in 20 patients by
geometric and nongeometric, counts-based techniques using data from first-pass and …

SUMMARY A new method for obtaining absolute left ventricular volume from gated blood
pool studies was evaluated in a torso phantom and in 35 patients who also underwent …

and an Automated Technique Page 1 Links et al. (1) and Starling et al. (2) introduced atten
uation-corrected count-based distance methods to deter mine left ventricular volumes using …

The prevalence of left ventricular (LV) dysfunction and resultant congestive heart failure is
increasing. Patients with this condition are at high risk for cardiac death and usually have …

Count rates observed at end-diastole and end-systole in the region of the left ventricle on
gated radionuclide angiograms were correlated with corresponding estimates by biplane …
