The Working Group on Cardiovascular Nuclear Medicine of the German Society of Nuclear Medicine has organised a multi-center study in which 13 institutes in the FRG participated. Data on equipment and methods employed in equilibrium radionuclide ventriculography and on results in 585 non-cardiac patients were obtained by means of a questionnaire. The global(More)
Voice and speech changes as a result of clinical treatment for 17 depressive and 15 schizophrenic patients were investigated. Speech samples taken at interviews before and after treatment were analyzed with regard to f0, spectral energy distribution, and formant frequencies of vowels occurring in identical phonetical context. Both groups of patients showed(More)
In a series of 12 patients presenting with a single-vessel coronary artery disease and who were injected with 370 MBq of 99mTc-2-methoxyisobutylisonitrile at peak exercise, two consecutive single photon emission computed tomography (SPECT) data collections, i.e., 32 views of 30 sec during a 180 degrees rotation and 64 views of 15 sec during a 360 degrees(More)
A fully automated computer program is described for processing equilibrium radionuclide ventriculography data with regard to global and sectorial left ventricular ejection fraction. The precise identification of the left ventricular outline, a prerequisite for reproducible determination of sectorial ejection fraction, was achieved by using morphological and(More)
In 19 patients with hypertrophic cardiomyopathy (15 males, 4 females, mean age 49.2 +/- 10.8 years) left ventricular function was studied with radionuclide ventriculography at rest and during exercise in a crossover design without intervention and after disopyramide and propranolol treatment. 15 of the 19 patients had a resting or latent intraventricular(More)
The aim of this study was to evaluate and validate a new quantification method for 99Tcm-sestamibi single photon emission computed tomographic (SPECT) myocardial imaging based on a four-slice analysis method and to check the functional results of percutaneous transluminal coronary angioplasty (PTCA). Using the calculated pathological area of the scintigram(More)
In 16 men with normal valvular function (group 1) and 23 men and one woman with isolated aortic regurgitation (group 2) effective stroke was determined by first-pass radionuclide ventriculography. Total left ventricular stroke volume was derived from equilibrium radionuclide ventriculography using a geometric approach for the end-diastolic volume multiplied(More)
