[Clinical utility of pulmonary 99mTc-Tetrofosmin uptake measurement by the exercise myocardial scintigraphy in patients with ischemic heart disease].

Increased pulmonary 201TlCl (Tl) uptake during exercise has been used as a marker of multivessel critical stenosis. We studied whether pulmonary 99mTc-Tetrofosmin (TF) uptake measurement during exercise is useful as an additional indicator for the detection of coronary artery disease. Pulmonary to myocardial uptake ratio (P/M) measured by TF scintigraphy during exercise were compared with findings of coronary angiography in eighty one patients with ischemic heart disease and also P/M measured with Tl in twenty one cases.

[The characteristics of 123I-MIBG myocardial scintigraphy in patients with left ventricular pressure-overload diseases].

The purpose of this study was to clarify the clinical significance of 123I-metaiodobenzylguanidine (MIBG) myocardial scintigraphy in patients with left ventricular pressure-overload diseases. MIBG scintigraphy was applied to 10 pts with aortic valve stenosis (AS group), 11 pts with hypertrophic obstructive cardiomyopathy (HOCM group), 17 pts with hypertrophic non-obstructive cardiomyopathy (HCM group) and 6 control cases (C group). Mean pressure gradient in AS and HOCM groups was 62 +/- 21 mmHg and 38 +/- 18 mmHg, respectively.

Comparison of phenotypic characteristics, DNA-DNA hybridization results, and results with a commercial rapid biochemical and enzymatic reaction system for identification of viridans group streptococci.

The rapid ID 32 Strep system (bioMérieux, Marcy l'Etoile, France) was evaluated for its ability to identify 21 species of viridans group streptococci; results were compared with DNA-DNA hybridization results and results of conventional physiological tests. A total of 171 strains of the 21 species including 147 clinical strains was analyzed. Of the 156 strains of species included in the database of this system, 136 strains (87%) were correctly identified.

[Identification of viable myocardium using 99mTc-tetrofosmin scintigraphy--comparison with 201Tl redistribution-reinjection images].

The purpose of this study was to clarify the diagnostic value of identifying viable myocardium using 99mTc-Tetrofosmin scintigraphy. Twenty-one patients with chronic coronary artery disease were studied using 201Tl exercise myocardial scintigraphy with reinjection and 99mTc-Tetrofosmin exercise myocardial scintigraphy. All patients had a history of old myocardial infarction.

[Comparison of inferior myocardial defect between planar and SPECT image of 123I-metaiodobenzylguanidine cardiac scintigraphy].

Discordant findings of inferior MIBG defect between SPECT and planar images were sometimes observed in the clinical studies. In this study, we compared inferior myocardial findings between planar and SPECT image of 123I-metaiodobenzyl-guanidine (MIBG) cardiac scintigraphy in 29 patients. All patients were estimated as normal in anterior accumulation of MIBG.

[Simultaneous evaluation of myocardial perfusion and fatty acid metabolism using dynamic SPECT with single injection of 123I-15-(p-iodophenyl)-3-methyl pentadecanoic acid (BMIPP)].

The purpose of this study is to clarify whether dynamic SPECT (DECT) immediately after the injection of 123I-15-(p-iodophenyl)-3-methyl pentadecanoic acid (BMIPP) may represent myocardial perfusion imaging. Ten patients with unstable angina pectoris (UAP), 11 patients with acute myocardial infarction (AMI) and 6 patients with non-ischemic heart disease (NIHD) were studied using BMIPP myocardial scintigraphy with DECT. DECT acquisition was started 2 minutes after the injection of BMIPP, and DECT images were obtained every three minute for 15 minutes with 3-headed gamma camera SPECT system.

[Initial myocardial uptake and myocardial clearance of 123I-metaiodobenzylguanidine in patients with ischemic heart disease of left ventricular dysfunction and dilated cardiomyopathy].

We studied initial myocardial uptake and myocardial clearance of 123I-metaiodobenzylguanidine (MIBG) in patients with ischemic heart disease of left ventricular dysfunction and dilated cardiomyopathy. Eleven patients with ischemic heart disease of left ventricular dysfunction (IHD group), 6 patients with dilated cardiomyopathy (DCM group) and 7 control cases (control group) were studied. Heart to mediastinum activity ratio (H/M) of early and delayed image was significantly lower in the IHD and DCM groups than in the control group.

[Artifactual defect of inferior myocardium on 123I-metaiodobenzylguanidine myocardial SPECT: characteristic findings and preventive method on phantom study].

Discordance between planar and SPECT image of inferior myocardial defect on 123I-metaiodobenzylguanidine myocardial scintigraphy (MIBG) was occasionally observed in the clinical studies. The purpose of this study is to clarify the existence of artifactual myocardial defect on MIBG SPECT image. Phantom study was performed in various kinds of situation using triple gamma camera.

Self-expanding stainless steel stent application in rectosigmoid stricture.

In recent years, several reports on the experimental and clinical applications of the Gianturco stent (self-expanding stainless steel stent) have been published. However, to our knowledge, the use of stents in rectosigmoid strictures has not been reported. We used self-expanding stainless steel stents to dilate rectosigmoid strictures caused by nonresectable recurrent neoplasm.

Population study on the adipose tissue distribution in Japanese women born in 1948.

We examined the relationship between body fat distribution and glucose metabolism and sex hormones in Japanese premenopausal women born in 1948. 1. There was a significant positive correlation shown between the waist circumference or skinfolds of the upper body, and the fasting insulin and C-peptide levels.
