Comparison of I-131, I-123 Absorbed Dose and Tc-99m in Thyroid Scanning Using MCNP Code in ORNL-MIRD Phantom
Introduction: Thyroid cancer is at the ninth from ten of common malignant cancer. A man has higher risk to get Thyroid cancer that a woman has. This organ is lain near human neck. The use of radioactive I-131, I-123 and Tc-99m for diagnosis of thyroid cancer has a risk where other organs around Thyroid will accept dose of radiation. One of the risks is large dose which is accep...
متن کاملa comparative study of the theme of "marriage" in three victorian novelists: charles dickens, george eliot and thomas hardy
این تحقیق کوشیده است با انتخاب پنج رمان از میان آثار برگزیده، «چارلز دیکنز»، «جورج الیوت» و «توماس هاردی » و با رویکردی تطبیقی به بررسی درونمایه ی «ازدواج» در آثار این سه رمان نویس بزرگ دوره ی ویکتوریا بپردازد. فرضیه ی اولیه ی تحقیق این بوده است که چارلز دیکنز (1870- 1812) با زبانی شوخ و گزنده، جورج الیوت(1880- 1819) با نگاهی آموزشی–اندرزگونه و توماس هاردی(1928- 1840) با رویکردی تلخ وانتقادی به...
Optimisation of Simultaneous Tl-201/Tc-99m Dual Isotope Reconstruction with Monte-Carlo-Based Scatter Correction
Simultaneous Tl-201/Tc-99m dual isotope myocardial perfusion SPECT is seriously hampered by down-scatter from Tc-99m into the Tl-201 energy window. This paper presents and optimises the ordered-subsets-expectation-maximisation-(OS-EM-) based reconstruction algorithm, which corrects the down-scatter using an efficient Monte Carlo (MC) simulator. The algorithm starts by first reconstructing the T...
متن کاملComparison of Tc-99m Ethylenedicysteine (Tc-99m EC) with Tc-99m DPTA in evaluation of renal disease [Persian]
Tc-99m-EC is a new renal radiopharmaceutical introduced as an alternative for Tc-99m MAG3. Twenty-three normal volunteers and patients in different .stages of renal disease were evaluated with Te-99m EC and Tc-99m DTPA. The mean initial uptake of EC was significantly higher as compared to DTPA. There was a high correlation between rectangular and hand-drawn ROls for kidney and background,...
متن کاملComparative assessment of renal Tc-99m DMSA scan and renal sonography findings in complication of urinary tract infections [Persian]
Urinary tract infection (UTI) is a common disease in childhood specially in female. In this study 50 patients with stablished diagnosis of UTI were evaluated by both renal scan with Tc-99m DMSA and renal sonography. The study revealed that most urinary tract infections are in children, Female sex between 5-9 years of age. Therefore the most important complications (Renal scarring) are als...
