The paper presents results of studies on the possibility using ultrafiltration method supported by sorption low-cost, easily accessible aluminosilicates to purify water contaminated with radionuclides. An aqueous solution radionuclides in form cations at different oxidation states—Cs(I)-137, Co(II)-60 and Am(III)-241—as well as pertechnetate anions—TcO4?-99m—was treated proposed hybrid method. ...

Ectopic thyroid is a congenital defect in which the thyroid gland is located away from the usual pretracheal location. Dual ectopic thyroid, which consists of two foci of thyroid tissue, is very rare. In this case dual ectopic thyroid with subclinical hypothyroidism in a 10-year-old-girl was reported. The absence of the thyroid gland in the pretracheal location was revealed by ultrasonography (...

Imaging of peripheral joints is a simple and valu able technique for evaluating joint disease in adults (1-12). It has been shown to be a sensitive index of inflammatory activity, occasionally revealing synovitis before the roentgenogram, laboratory studies, or even physical examination is positive (1-13). These studies document the presence and location of inflammed synovium and reflect progre...

Twenty-eight knees with chronic arthritis and effusion were treated with intra-articular 90Y. Synovial activity was assessed by measuring 99mTc pertechnetate uptake. There was a significant difference in uptake between controls and patients. Those who had a good response to 90Y (15 patients) showed a significant decrease in uptake, not seen in those who failed to respond. The pattern of 90Y dis...

Poorly differentiated insular thyroid carcinoma is classified as a separate entity among other tumors of the thyroid gland. Its histological pattern and clinical course are regarded as intermediate between well-differentiated and anaplastic thyroid cancer. The authors report Tc-99m pertechnetate, Tc-99m MDP and radioiodine imaging features in a 33-year-old male patient with metastatic insular c...

Three cases of imaging with 99mTc-pertechnetate (99mTcO4) and unusual positive lymph node uptake in the neck are reported hereby. Two cases were later diagnosed to be well-differentiated thyroid carcinoma, (DTC) with nodal metastasis. The third was a confirmed case of carcinoma thyroid that had presented with mass in the neck soon after surgery, being prepared for ablative dose of radioactive i...

New film materials for pertechnetate: A new film material comprised of quaternized poly(4vinylpyridine) cross-linked with 1,10-diiododecane has been developed for use in the spectroelectrochemical sensor. Films were prepared in a one-pot synthesis by stirring poly(4vinylpyridine), cross-linker and methyl iodide in 1-butanol for 1 h, after which the solution was spincoating onto ITO-glass. Film ...
