Meckel's diverticulum is a common congenital disorder which may result in Gl bleeding. For definite diagnosis before surgery, radiographic procedures such as small intestine barium studies are not greatly successful; on the other hand Tc-99m-Pertechnetate imaging is a physiologic and noninvasive method with high sensitivity and specificity. In this report, three patients with rectorrhagia...

A 37-year-old male with a persistent increased parathyroid hormone level, after subtotal thyroidectomy and parathyroidectomy, was referred for scintigraphic localization of a possible ectopic parathyroid adenoma. Tc-99m pertechnetate and Tc-99m MIBI scintigraphy were performed on separate days. There was marked uptake of both tracers in the mediastinum, which at surgery was confirmed to be an e...

We have compared [Tc-99m] sodium pertechnetate with Tc-99m glucoheptonate in 52 patients studied for various brain lesions. Flow studies as well as delayed scans were performed in all. Especially in primary and metastatic lesions of the posterior fossa, the diagnostic yield was improved by the delayed glucoheptonate (GH) scans. In contrast, no advantage of GH over pertechnetate could be detecte...

The extraction of pertechnetate ions from aquous solutions containing various concentrations of nitric acid into hydrophobic ionic liquids (ILs) has been examined at 25, 50 and 70 °C. The results show that the distribution ratio of Tc (DTc) between both phases weakly depends on the temperature and HNO3 concentration when IL's with relatively short aliphatic chains are used. The DTc obtained for...

OKUYAMA, S., MISHINA, H., YAMAGAT A, R., YAMAMOTO, K., NAGASHIMA, H. and TAIMA, T. A Case o f Early Ga.~tric Cancer Whose Diagnosis Was Expedited by Amogastrin-99n°Tc Pertechnetate Scintigraphy. Tohoku J, exp. Med., 1982, 137 (2), 231-232 99mTc pertechnetate imaging of the stomach was carried out in a case of 63-year-old man 15 min after amogastrin. A coldness on the scintigram led to an explor...

UNLABELLED 99mTc-pertechnetate scintigraphy plays an essential role in the management of a variety of thyroid and parathyroid disorders. The authors report an unusual case of mediastinal tracer distribution of 99mTc-pertechnetate and 99mTc-MIBI in relation to an oesophageal conduit following oesophago-gastrectomy and reconstructive surgery on thyroid scintigraphy. This is a rare but important c...

UNLABELLED Our objective was to evaluate the role of (99m)Tc-pertechnetate scintigraphy on microvascular autologous transplantation of the submandibular gland in patients with severe keratoconjunctivitis sicca (KCS). METHODS (99m)Tc-Pertechnetate scintigraphy was performed on 106 patients with severe KCS. The patients were examined before surgery and at 1 wk and 3 mo afterward using a standar...
