PURPOSE The purpose of this study was to investigate whether the findings of Tc-99m pertechnetate salivary gland scintigraphy (SGS) can predict the outcome of sialoendoscopic intervention in patients with obstructive submaxillaritis. MATERIALS AND METHODS Eleven patients with obstructive submaxillaritis were prospectively recruited. All patients underwent sialoendoscopy. Tc-99m pertechnetate ...

BACKGROUND High-intensity focused ultrasound (HIFU) allows to inflict intracorporal thermal lesions without penetrating the skin or damaging the surrounding tissue. This analysis intends to assess the magnitude of HIFU-induced ablations within benign thyroid nodules using scintigraphic imaging with (99m)Tc. METHODS Ten cold, hot, or indifferent nodules were treated using multiple pulses of HI...

UNLABELLED This study assesses the effectiveness of using everyday cleaning agents for the radioactive decontamination of wet (99m)Tc-pertechnetate spills in the nuclear medicine department. METHODS Six cleaning agents (water, water and soap, alcohol, bleach, a commercial glass cleaner, and a commercial decontaminating agent) were analyzed for decontamination effectiveness for a wide range of...

We analyze the case of a patient with intermittent episodes of lower gastrointestinal bleeding and suspected Meckel's diverticulum, whose presence was confirmed by (99m)Tc-pertechnetate scintigraphy. A previous exploratory laparotomy had been performed without finding the diverticulum. In spite of years of medical treatment, the patient presented a new episode of lower gastrointestinal bleeding...

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...

This study investigated the microleakage of two different root canal obturation systems, using the nuclear medicine approach, with sodium pertechnetate Tc. Twenty six single-rooted extracted teeth were selected. The crowns were sectioned to obtain 15 mm long root segments and each tooth was prepared using rotary ProFile instruments. The roots were divided into 2 experimental groups and two cont...

  Tc-99m pertechnetate scintigraphy is the modality of choice for diagnosis of Meckel's diverticulum. Interpretation of Meckel's scan identifies a focal area of radiopharmaceutical uptake in the anterior abdomen similar to normal gastric mucosa. The activity must be of the same pattern and intensity as gastric uptake. We present a 13-year-old patient with gastrointest...

Technetium ((99)Tc) is an abundant, long-lived radioactive fission product whose mobility in the subsurface is largely governed by its oxidation state. Tc immobilization is crucial for radioactive waste management and environmental remediation. Tc(IV) incorporation in spinels has been proposed as a novel method to increase Tc retention in glass waste forms during vitrification. However, experim...

  A 13 years old boy with severe abdominal pain and history of intermittent (II bleeding since the aye of 3 months, is presented. Different diagnostic procedures were unremarkable. A Tc-99m Pertechnetate abdominal study revealed abnormal radionuclide accumulation in small bowel region. Duplication of small bowel was suspected which was confirmed by surgery and patholo...
