BACKGROUND Diagnosis of protein loss into the gastrointestinal tract using noninvasive techniques is challenging. In people, scintigraphy not only is a sensitive tool to confirm protein-losing enteropathy (PLE), but it also allows for localization of protein loss. HYPOTHESIS/OBJECTIVES To investigate the feasibility of 99m Tc-labeled human serum albumin (HSA) scintigraphy in dogs with PLE in ...

Abstract Purpose The aim of this systematic literature review was to obtain an overview when administer the diuretics in relation radiopharmaceutical during a diuresis renography. Methods A search performed three different databases (Embase, PubMed/Medline and Cochrane Library) together with information specialist. question was: should be administered renography? Studies adults were included gu...

The aim of this study was to investigate gamma radiation-induced oxidative damage in erythrocytes after 201Tl myocardial perfusion scintigraphy. Twenty patients (8 women and 12 men) who performed 201Tl myocardial perfusion scintigraphy were included in this study. The blood samples were taken from patients just before, 1 hour after and three hours after injection of the radiopharmaceutical. Mal...

During the carcinogenesis process, tumour cells often have a more rapid proliferation potential than cells that participate in blood capillary formation by neoangiogenesis. As a consequence of the poorly organized vasculature of various solid tumours, a limited oxygen delivery is observed. This hypoxic mechanism frequently occurs in solid cancers and can lead to therapeutic resistance. The pres...

UNLABELLED Our objective was to develop a software application that allows us to easily manage a portable database of information on radiopharmaceutical interactions with drugs or other agents and on radiopharmaceutical adverse effects. METHODS The application was developed and compiled with a commercially available data management system and programming language. All data entered into the da...

This paper presents the establishment of a quality control program and correction factors for the geometry of the vials used for distribution of radiopharmaceutical and activimeters calibration. The radiopharmaceutical produced by IPEN 67Ga, 131I, 201Tl and 99mTc had been tested using two different vials. Results show a maximum variation of 22% for 201Tl, and the minimum variation was 2.98% for...

Quality control (QC) procedures should always be performed following radiopharmaceutical preparation and prior to patient administration. The main aim of QC is to ensure optimal radiopharmaceutical product properties except for some short half-life tracers such as some positron emission tomography (PET) imaging probs. by dispensing a radiopharmaceutical of the highest quality the risk of having...
