Estimated collective effective dose to the population from nuclear medicine diagnostic procedures in Croatia: A comparison of 2010 and 2015.

Objective: This study presents national surveys of patient exposure from nuclear medicine (NM) diagnostic procedures in 2010 and 2015 in the Republic of Croatia.

Methods: The survey was performed according to the European Commission Dose DataMed (DDM) project methodology. 28 most frequent NM diagnostic procedures were identified.

Incremental value of Tc-HYNIC-TOC SPECT/CT over whole-body planar scintigraphy and SPECT in patients with neuroendocrine tumours.

Aim: The aim of this study was to evaluate the additional value of Tc-HYNIC-TOC SPECT/CT over planar whole-body (WB) scintigraphy and SPECT alone in the detection and accurate localisation of neuroendocrine tumour (NET) lesions.

Methods: This study included 65 patients with a definitive histological diagnosis of NET prior to scintigraphy. Planar WB scintigraphy, SPECT, and SPECT/CT images were acquired at 4 h post-administration of 670 MBq Tc-HYNIC-TOC.

99mTc-EDDA/HYNIC-TOC in management of patients with head and neck somatostatin receptor positive tumors.

Background: Aim of this study was to determine the value of technetium-99m-hydrazinonicotinyl-Tyr3-octreotide (99mTc-ED-DA/HYNIC-TOC) in patients with somatostatin receptor (SSR) positive tumors of head and neck region.

Material And Methods: A total number of 16 patients were enrolled in this study. Planar whole body (WB) and single photon emission computed tomography (SPECT) images were acquired at 2 and 4 hours after the injection of approximately 670 MBq of 99mTc-EDDA/HYNIC-TOC.

How to treat an extensive form of primary intestinal lymphangiectasia?

We report a case of a 42-year-old man with a rare disorder known as primary intestinal lymphangiectasia, which is characterized by dilated intestinal lymphatics that lead to the development of protein-losing enteropathy. The patient presented with a grand mal seizure caused by malabsorption-derived electrolytes and a protein disorder. Signs of the disease, including chronic diarrhea and peripheral edema, manifested 10 years ago, but a diagnosis was never made.
