Emission computed tomography with technetium-99m pyrophosphate was used to delineate the location and estimate the size of myocardial infarcts in 20 patients with documented acute myocardial infarction. Tomography was performed after planar imaging within 2-5 days after the onset of infarction. A series of transaxial, frontal, and sagittal tomograms were reconstructed from 32 views imaged from ...

Aim: This study aimed to determine the normal range for thyroid uptake of technetium-99m (99mTc) pertechnetate in a Turkish population.Methods: The retrospective included 73 (54 females, 19 males) consecutive euthyroid patients, all whom underwent scintigraphy using 99mTc-pertechnetate as component parathyroid adenoma localization. value at 20th minute was calculated each patient.Results: mean ...

A method of liver scanning based on a subtraction technique with simultaneous use of two tracers, 67Ga-citrate and 99mTc-sulfur colloid, is described. The subtraction technique isolates radiogallium uptake by the space-occupying hepatic lesions by subtracting interference due to tracer uptake by healthy hepatic tissue. In 82 patients, the method yielded a correct result in 94.7% of the positive...

Technetium-99m-phosphate compounds used in bone scanning are excreted by the kidney, and excellent renal images can be obtained on routine bone scintigrams. The preoperative bone scans of 49 patients who underwent radical nephrectomy for renal cell carcinoma between 1981 and 1985 were reviewed for renal imaging. Ninety-four percent of the patients had abnormal bone scan renal images (82% had fo...

TMPP (5, 10, 15, 20 tetrakis {4-methoxyphenyl} 21H, 23H porphyrin) was labeled with technetium-99m via direct labeling technique using stannous chloride as a reducing agent. The optimum conditions that gave high labeling yield (95.2%) of Tc-TMPP complex were achieved by using 3mg TMPP, 100g SnCl2.2H2O, at pH 3 and 30min reaction time. Accumulation of Tc-TMPP complex was studied in tumor bearin...

Abstract [ 99m Tc] fonturacetam hydrazide was radiosynthesized to assess neuropsychiatric disorders by targeting the brain. The nootropic drug labeled with technetium-99m, and factors affecting labeling yield were studied. At optimum conditions, radiocomplex obtained at a high radiochemical (98.9%) stable in saline for up 36 h serum more than 24 h. Labeled characterized assessed silico. Biodist...
