This study aims to investigate the radioprotective effects of dimethyl sulfoxide in acute phase radiation-induced lung injury by technetium-99m-diethylenetriaminepentaacetic acid transalveolar clearance scintigraphy a rabbit model. Twenty white New Zealand rabbits were grouped as (1) control, (2) sham irradiation, (3) irradiation plus sulfoxide, and (4) alone. Right hemithorax regions groups ir...

We describe two cases of right hyperglycemia hemichorea (HGHC) with identical Tc-99m TRODAT-1/ Tc-99m ECD scan findings. While the brain MRI showed signal alterations within the left putamen, there was evidence of hyperperfusion on Tc-99m TRODAT-1 but hypoperfusion on Tc-99m ECD within the left putamen, in association with hyperperfusion within left thalamus on Tc-99m ECD. The discrepancy betwe...

Abstract Background Metastases to the bones are a frequent location of metastasis in advanced breast cancer and responsible for substantial morbidity healthcare expenses. Imaging has been crucial directing patient therapy decades, contributing staging response evaluation skeleton. This research aimed assess diagnostic value whole-body magnetic resonance imaging with diffusion-weighted added rad...

The goal of this work was to test whether an antibody-based agent approved for use as a single-photon-emitting imaging agent when radiolabeled with technetium-99m could be labeled comparably with a positron-emitting nuclide, technetium-94m. "Instant kits" containing lyophilized NP-4 antibody Fab' fragment of an anticarcinoembryonic antigen IgG (CEA-Scan) from the same manufactured lot were reco...

A 22-year-old female patient with severe hypertension underwent both Technetium-99m diethylenetriaminepentaacetate and Technetium-99m mercaptoacetyltriglycine basal and captopril renal scintigraphy. While no significant change was seen with Tc-99m DTPA, there was left sided parenchymal retention of captopril Tc-99m MAG3 suggesting renal artery stenosis which was confirmed by angiography.

The findings on 99mTc dimercaptosuccinic acid (DMSA) scans were examined in 54 patients aged 3 to 33 years in whom renal scarring had been diagnosed radiologically in childhood after urinary tract infection. There was no recent history of infection. Vesicoureteric reflux had been present in 48 patients and had stopped in 23 at the time of the DMSA scan. In six of the 72 radiologically scarred k...

OBJECTIVE Urinary tract infection (UTI) is one of the most common causes of febrile pediatric diseases. Also, vesicoureteral reflux (VUR) is a significant risk factor for UTI. Voiding cystourethrography (VCUG) is the method of choice for evaluation of VUR. This study was done to predict VUR by DMSA scan (technetium 99 m-labeled dimercaptosuccinic acid) and ultrasonography (US). METHODS In a p...

6-Hydrazinonicotinic acid (HYNIC, 1) is a well-established bifunctional technetium-binding ligand often used to synthesise bioconjugates for radiolabelling with Tc-99m. It is capable of efficient capture of technetium at extremely low concentrations, but the structure of the labelled complexes is heterogeneous and incompletely understood. In particular, it is of interest to determine whether, a...

Objective: To determine the feasibility of hepatobiliary iminodiacetic acid in the evaluation of small bowel obstruction in adults. Patients and Methods: This was a pilot study of the feasibility of technetium 99m hepatobiliary iminodiacetic acid in the evaluation of small bowel obstruction. A total of 8 patients clinically suspected to have small bowel obstruction were recruited in this study ...
