99mTc-Macroaggregated Albumin (99mTc-MAA) has been used as a perfusion agent. This study described development of the 68Ga-MAA via commercially available kits from Pars-Isotopes Company as a 99mTc-MAA kit. 68Ge/68Ga generator was eluted with suprapure HCl (0.6 M, 6 mL) in 0.5 mL fractions. The two fractions with the highest 68GaCl3 activity were generally used for labeling purposes. After label...
The radioisotope Technetium-99m has unique chemical and nuclear properties; which is widely used in the field of nuclear medicine. This isotope has a half-life of 6.04 hours and the emitted gamma ray has energy of 140.5 keV. This radioisotope is not normally found in nature, but is obtained from radioisotope molybdenum99 decay. molybdenum99 has half-life of 66 hours, and 740 keV Gamma-ray....

*Corresponding author: Dr. S. Rasoul Zakavi, Nuclear Medicine Research Center, Emam Reza Hospital, School of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran. Fax: +98 511 8419521 E-mail: [email protected] Background: 99mTc is a widely used radioisotope in nuclear medicine centers which is obtained by elution from Mo-99/Tc-99m generators. Usually the generators are either suppli...
از رادیوداروی99mtc به عنوان اسب بارکش بخش پزشکی هسته ای نام می برند. این رادیودارو از دوشیدن ژنراتور99mo -99mtc بدست می آید. چشمه ی این رادیودارو99mo است که درون ستون استوانه ای شکل ژنراتور قرار می گیرد و پس از نیمه عمر واپاشی خود 99mtc حاصل می شود. عواملی روی کارکرد ستون درون ژنراتور تأثیرگذارند که باعث می شود ستون در هنگام دوشیدن ژنراتور و در هنگام جداسازی همه ی 99mo را جذب نکند و محلول 99mtc...
Bone metastases, often a consequence of breast, prostate, and lung carcinomas, are characterized by an increased bone turnover, which can be visualized by positron emission tomography (PET), as well as single-photon emission computed tomography (SPECT). Bisphosphonate complexes of 99mTc are predominantly used as SPECT tracers. In contrast to SPECT, PET offers a higher spatial resolution and, ow...
