Effect of EHDP on calcium accumulation and technetium-99m pyrophosphate uptake in experimental myocardial infarction.
Ethane-l-hydroxy-1,1-diphosphonate (EHDP) inhibits bone mineral growth. This study was performed to test the hypothesis that EHDP would interfere with the process of calcium uptake and deposition in evolving myocardial infarction and thereby influence other parameters, including technetium-99m pyrophosphate (Tc-99m PYP) uptake and scintigraphic visualization of the infarcts. Permanent occlusion...

متن کاملThe specificity of the diffuse pattern of cardiac uptake in myocardial infarction imaging with technetium-99m stannous pyrophosphate.
To analyze the specificity of the diffuse pattern of cardiac uptake with technetium-99m stannous pyrophosphate (TcPYP), we evaluated the bone scans of 1,383 noncardiac patients and the myocardial scintigrams of 120 cardiac patients. Seventy (14.4%) of 483 bone scans performed on a scintillation camera revealed diffuse TcPYP cardiac uptake. Among the total 603 camera bone scans and myocardial sc...
متن کاملFollow-up technetium-99m stannous pyrophosphate myocardial scintigrams after acute myocardial infarction.
Technetium-99m stannous pyrophosphate (99mTc-PYP) myocardial scintigrams were obtained in 68 patients during acute myocardial infarction (AMI) and at follow-up 15.9 +/- 8.8 weeks later. All patients with AMI had a positive scintigram (2+ or greater); only one of 46 control patients (2%) had a positive (2+) scintigram. At follow-up scintigraphy 6 to 37 weeks following AMI, 57% of patients had a ...
متن کاملTechnetium-99m pyrophosphate uptake in experimental viral perimyocarditis. Sequential study of myocardial uptake and pathologic correlates.
The myocardial uptake of technetium-99m pyrophosphate (99mTc-PYP) in perimyocarditis induced by coxsackievirus B3 in BALB/c mice was studied. 99mTc-PYP uptake ratio, measured by the ratio of counts/min per gram for the heart to counts/min per gram for the skull, began to increase 5 days after virus inoculation when myocardial necrosis was evident. On the seventh day after the inoculation, 99mTc...
