To determine the factors associated with 20 minute Tc-99m pertechnetate thyroid uptake, we examined all patients in whom thyrotoxicosis was diagnosed at Chiba-Hokusoh Hospital, Nippon Medical School from 2001 April through 2003 March. Patients with thyrotoxicosis diagnosed during this period were 57 with Graves' disease (76%), 11 with transient hyperthyroxinemia (TH)(14.7%), and 7 with subacute...

To the Editor: The development and introduction of the UltraTag® kit (Mallinckrodt, Inc., St. Louis, MO) offered a substantial improvement in the ability to conveniently and efficiently radiolabel red blood cells with mTc (1 ). This particular cell-labeling technique is especially desirable for use in studies of gastrointestinal hemorrhage (GI bleed) since even minimal levels of free pertechnet...

OBJECTIVE The purpose of this study was to investigate if an octadecyl (18C) minicolumn could be applied successfully for quality control of 99mTc exametazime (HMPAO). METHODS The 18C column system using saline eluent was validated against the Whatman 17 method in calculating the percent radiochemical purity of 99mTc-HMPAO. The behavior of 99mTc-pertechnetate (99mTc04-) and hydrolyzed-reduced...

Leonidas, J. C., and Germann, D. R. (1974). Archives of Disease in Childhood, 49, 21. Technetium-99m pertechnetate imaging in diagnosis of Meckel's diverticulum. Abdominal imaging after intravenous injection of 99mTc pertechnetate is a simple, safe, and noninvasive diagnostic procedure to show ectopic gastric mucosa, which is present in most cases of symptomatic Meckel's diverticulum. It was pe...

Technetium-99m aprotinin was prepared from an optimised radiolabelling kit formulation containing aprotinin, alkaline buffer and stannous chloride (reducing agent) and radiolabelled using (99m) Tc-pertechnetate. The labelling was achieved within 25 min, with radiochemical purities of >98%.

We report a three-phase bone scintigraphy for the diagnosis of a peripheral bone lesion caused by systemic sarcoidosis. A 32-year-old man with suspected osteomyelitis of the right forefinger underwent three-phase bone scintigraphy with Tc-99m hydroxymethylene diphosphonate (HMDP) and single-photon emission computed tomography/computed tomography (SPECT/CT). The lesion was rich in blood flow acc...

The aim of this study was to highlight the contribution bone scintigraphy in assessment extension osteophilic cancers Senegal. This a retrospective study, with descriptive and analytical purpose, carried out over period four (04) years between January 01, 2018 December 31, 2021. It focused on files patients who underwent for an cancer during period. According prostate by far most representative...

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...
