INTRODUCTION Variceal haemorrhage is a potentially life-threatening complication in cirrhotic patients. Identification of patients at high risk for bleeding is particularly important. The aim of this study was to determine the clinical usefulness of per-rectal portal scintigraphy (PPS) in the evaluation of the severity of portal hypertension in cirrhotic patients, in terms of correlation betwee...

OBJECTIVE To investigate in vivo and in humans the mechanisms and kinetics of vagina-to-uterus distribution. DESIGN Controlled clinical study. SETTING Volunteers in an academic research environment. PATIENT(S) Six postmenopausal women undergoing transabdominal hysterectomy were selected. INTERVENTION(S) Women received 0.2 mL of (99m)Tc-pertechnetate vaginally. In three patients the cerv...

BACKGROUND Hyperthyroid patients commonly complain of generalized bony aches, which are frequently overlooked due to the more prominent symptoms of cardiovascular and nervous disturbances. Hyperthyroid patients are expected to have abnormal bone metabolism as part of the generalized hypermetabolic status. The aim of this study is to verify the presence of metabolic bone superscan in association...

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...

objective(s): to review the findings of the patients with sjögren’s syndrome (ss) having technetium-99m-pertechnetate (99mtc-pertechnetate) and gallium-67 citrate (ga-67) salivary gland scintigraphy in the past eight years.methods: the patients with ss, who were referred to our department for salivary gland scintigraphy during january 2008-december 2015 were studied using both 99mtc-pertechneta...

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 ...

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...

Ginkgo biloba extract (EGb) is a phytotherapeutic agent used for the treatment of ischemic and neurological disorders. Because the action of this important extract is not fully known, assays using different biological systems need to be performed. Red blood cells (RBC) are labeled with technetium-99m (Tc-99m) and used in nuclear medicine. The labeling depends on a reducing agent, usually stanno...
