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...

Left hemiparesis exhibited during the post-eruptive stage of exanthem subitum (ES) in an 11-month-old girl. Tc-99m HMPAO brain SPECT showed diffuse hypoperfusion in right hemisphere. Hemiparesis has occasionally been reported as central nervous system (CNS) complications of ES, and Tc-99m HMPAO brain SPECT was useful for evaluating of CNS involvement.

OBJECTIVE The aim of this study was to demonstrate the functional compensation that occurs in kidneys which accompany a partner with total or partial loss of renal functioning mass, using camera-based Tc 99m MAG3 clearance technique. MATERIAL AND METHODS Eighty five patients (43M, 42F, age: 44.8±12.6, range: 18-77 years) with normal serum creatinine levels and normal (<Grade 1) Tc 99m MAG3 re...

BACKGROUND Technetium-99m sestamibi scintigraphy has become one of the most popular techniques for localization of the parathyroid gland after failure of primary neck exploration. OBJECTIVE To examine the efficacy of sestamibi with the hand-held gamma ray detecting probe for the identification of parathyroid adenomas during revision parathyroidectomy. METHODS We reviewed six cases of probe-...

A photocrosslinkable trehalose derivative carrying mesogenic groups was synthesized by esterification reactions. The derivative (TC-HBPHA) was synthesized by the reaction of partially cinnamoyl-modified trehalose (TC4) with 4-(4-hexyloxybenzoyloxy)phenoxy-6-oxohexanoic acid (HBPHA) as a mesogenic unit. TC-HBPHA showed a nematic liquid crystalline mesophase at a temperature range from 150 °C to ...

BACKGROUND Ultrasound (US) and technetium-99m sestamibi scintigraphy (MIBI) are used to determine the localization of abnormal glands in cases of primary hyperparathyroidism (PHPT). Intraoperative intact parathyroid hormone (iPTH) monitoring is a reliable examination used to cure PHPT. The aim was to assess the necessity of intraoperative iPTH monitoring. METHODS Sixty patients were examined ...

AIM To evaluate the role of 99m-technetium methylene diphosphonate (Tc-99m MDP) bone scintigraphy on the detection of joint damage in asymptomatic alpine ski racers. MATERIALS AND METHODS This study included 20 male asymptomatic alpine ski racers (age range: 18-21 years). None of the skiers had a history of ski crashes. Bone scan findings of the racers were examined with Tc-99m MDP bone scint...

Scintigraphy with Tc-99m dimercaptosuccinic acid (DMSA) is considered a reference method for assessment of parenchymal lesions and estimation of differential kidney function. The aim of study was to evaluate Tc-99m mercaptoacetyltriglycine (MAG3) dynamic renal scintigraphy for the same purpose. 188 patients, submitted to both studies within three months, were divided in two groups. In the first...

The purpose of this study was to determine the number of weekly acquisitions permissible using a mobile PET/SPECT scanner for myocardial perfusion/viability imaging in an intensive care unit (ICU) based on the effective dose to patients and staff. The effective dose to other patients and staff in an ICU was calculated following recommendations from the American Association of Physicists in Medi...
