Introduction: 99m Technetium -Mebrofinate SPECT-CT scan is a pre-operative investigation useful in assessing the global, lobar and dynamic liver function. The study aimed at discordance function (scintigraphy) within given volume of remnant to assess if variation related primary indication for resection. Methods: All patients who underwent Tc-Mebrofenin unit since 2018 were included. Data proce...
Pentavalent technetium-99m dimercaptosuccinic acid ((99m)Tc-(V)DMSA) is a tumor-seeking agent which was introduced to evaluate, image, and manage many types of cancers. In this review, the beginning of, and the most recent applications of using this agent was appraised. The relation with tumor cell detection and proliferation was reported and several mechanisms of uptake of (99m)Tc-(V)DMSA in t...
A 34-year-old man was admitted with dull left-sided back pain. Physical examination revealed no abnormalities. Routine laboratory investigations including tumor markers were normal. Chest computed tomography demonstrated a heterogenous soft tissue tumor associated with destruction of the tenth rib in the left posterior mediastinum (Picture 1). Technetium-99m methylene diphosphonate bone scan sh...
We present an autopsy case of primary leptomeningeal melanoma visualized with technetium-99m-hexamethylpropyleneamine oxime (Tc-99m-HMPAO) single photon emission CT (SPECT) of the brain. Increased uptake of Tc-99m-HMPAO coincided with leptomeningeal enhancement on MR images and with the tumor location of the autopsy findings. It was thought that Tc-99m-HMPAO could correlate closely with melanom...
Liposomes are phospholipid nanoparticles used for targeted drug delivery. This study aimed to determine whether intravenous liposomes accumulate in lamellar tissue during laminitis development in horses so as to assess their potential for targeted lamellar drug delivery. Polyethylene-glycol (PEG) coated liposomes were prepared according to the film hydration method and labelled using (99m)Tc-he...
The aim of the present study was to explore the feasibility of lentiviral-mediated sodium iodide symporter (NIS) gene delivery for monitoring bone marrow-derived mesenchymal stem cell (BMSC) transplantation into the infarcted myocardium. For this purpose, we constructed a lentiviral vector (Lv-EF1α-NIS-IRES-EGFP) expressing NIS and enhanced green fluorescent protein (EGFP), and introduced it in...
Background: Technetium-99m radioisotope is the backbone of any nuclear medicine institute. This radioisotope is acquired by the elution of Molybdenum-99/Technetium-99m generator which emits 141 keV gamma ray and having 6.04 hour half-life. Occasionally the contents of Molybdenum-99 may mix up with elute, which may affect image quality and patients may receive higher doses than recommended. This...
