Over the past decades, the diagnostic methods and therapeutic tools for thyroid cancer (TC) have been greatly improved. In addition to the classical method of ingestion of radioactive iodine-131 (I131) and subsequent I123 and I124 positron emission tomography (PET) in therapy and examination, I124 PET-based 3-dimensional imaging, Ga68-labeled [1, 4, 7, 10-tetraazacyclododecane-1, 4, 7, 10-tetra...

w Myocardial perfusion imaging (MPI) in acute myocardial infarction (MI) has had its ups and downs over the past 4 decades (1). “Cold-spot” imaging with thallium-201, technetium-99m tetrofosmin and sestamibi, wall motion assessment with gated radionuclide angiography, and “hot-spot” imaging with radionuclide-bound pyrophosphate, glucarate, antimyosin, annexin V (2), and more recently, duramycin...

A62-year-old woman with a history of vasospastic angina presented to the emergency room with chest pain. The ECG showed ST-segment elevation in leads V3 through V6. The transthoracic echocardiogram revealed an akinetic left ventricular (LV) apical wall. The coronary angiogram on admission demonstrated normal coronary arteries. Two weeks later, resting Tc-tetrofosmin myocardial single photon emi...

UNLABELLED This study was done to examine the effect of asiaticoside on MCF-7 cell uptake of (99m)Tc-tetrofosmin ((99m)Tc-Tfos) and (99m)Tc-sestamibi ((99m)Tc-MIBI). METHODS The 3-(4,5-dimethylthiozol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was used to evaluate the effect of a 50% inhibitory concentration of asiaticoside on MCF-7 cell proliferation. MCF-7 cells were treated with 10,...
