The latter has to be reconstituted with 99mTc pertechnetate
to yield TTF, which will be used in combination with SPECT.
Sensitivity was assessed by imaging a small size source of sodium pertechnetate
(46 MBq), positioned near the center of the field of view and on the rotation axis, for a period of 10 min.
Thyroid replacement therapy can interfere with the uptake of Tc-99m pertechnetate
and therefore should be started as soon as the scan is completed.
Comparative scanning of thyroid nodules with technetium-99m pertechnetate
and technetium-99m methoxyisobutylisonitrile.
Taking into consideration the patient's splenectomy the possibility of ectopic splenic tissue was entertained and a radionuclide pertechnetate
liver-spleen scan was organised.
Treatment of pigmented villonodular synovitis of the knee with yttrium-90 silicate: prospective evaluations by arthroscopy, histology, and 99mTc pertechnetate
The maximum recommended quantity of pertechnetate
(3700 MBq, or 100 mCi, in 6 mL of sterile eluate) was used to reconstitute the kit to minimize the volume of mebrofenin to be injected.
(Meckel scan) scintigraphy has an overall diagnostic accuracy of 90% in MD with ectopic gastric mucosa, (1) but has been less utilised with multi-slice CT advances prompting improved detection on CT scan.
While awaiting technetium pertechnetate
radionuclide scan and Meckel scan, the patient's melena resolved and his hemoglobin stabilized on day two.
INDICATIONS AND USAGE: Sodium Pertechnetate
Tc 99m Injection is used IN ADULTS as an agent for: Brain Imaging (including cerebral radionuclide angiography), Thyroid Imaging, Salivary Gland Imaging, Placenta Localization, Blood Pool Imaging (including radionuclide angiography), Urinary Bladder Imaging (direct isotopic cystography) for the detection of vesico-ureteral reflux, Nasolacrimal Drainage System Imaging.
Important Risk and Safety Information for Sodium Pertechnetate
On Tc99m pertechnetate
thyroid scan, the tracer uptake was prominently low (Figure 1).
