Technetium-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...
متن کاملEffect 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 کاملMyocardial Uptake of Technetium-99m Stannous Pyrophosphate Following Direct Current Transthoracic Countershock
The effect of direct current (DC) countershock upon myocardial technetium-99m stannous pyrophosphate (PYP) uptake was studied in 22 dogs. All eight dogs imaged had positive abnormal PYP scintigrams that were usually indistinguishable from experimental infarction. In three animals, additional areas of radionuclide uptake were seen in overlying noncardiac tissue. Left and right ventricular myocar...
