Comparison 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 کاملQuantitative evaluation of normal uptake of mandibular condyle in bone scan with Tc 99m-MDP [Persian]
Unilateral condylar hyperplasia is the main cause of mandibular asymmetry. Radionuclide bone scanning is a useful procedure for functional evaluation of temporomandibular joint. In this study, 39 patients with normal bone scan and no facial asymmetry were studied. All patients were below 22 years of age. Normal condylar uptake was determined in this group of patients. Right & left condyla...
متن کاملEffect of Technetium-99m on lodine-131 Thyroid Uptake Measurements
Following administration of 2.5-5.0 mCi f 9mTc]pertechnetate, several hundred microcuries may be present in the necks of hyperthyroid patients after 6 hr. Coincidence summing of Tc-99m photons may disturb 1-131 uptake measurements in such patients if an oral diagnostic dose of 1-131 is administered immediately after completion of a f 9mTc]pertechnetate scintigram. Using a lower discriminator le...
متن کاملComparison of Tc-99m MDP, Tc-99m HSA and Tc-99m HIG uptake in rheumatoid arthritis and its variants.
Tc-99m polyclonal immunoglobulin-G has been shown to be a successful agent in the depiction of active inflammation in rheumatoid arthritis (RA). The objective of this study was to compare the uptake behaviors of Tc-99m HIG and Tc-99m MDP in RA and variants of rheumatoid arthritis (VRA). Seventeen patients with RA and 8 patients with VRA presenting with active inflammation were included in this ...
متن کاملComparison 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...
