Abstract [ 99m Tc] fonturacetam hydrazide was radiosynthesized to assess neuropsychiatric disorders by targeting the brain. The nootropic drug labeled with technetium-99m, and factors affecting labeling yield were studied. At optimum conditions, radiocomplex obtained at a high radiochemical (98.9%) stable in saline for up 36 h serum more than 24 h. Labeled characterized assessed silico. Biodist...

Despite recent advances in therapeutic and diagnostic approaches, coronary artery disease (CAD) and its related cardiac disorders represent the most common cause of death in the United States. Nuclear myocardial perfusion imaging (MPI) technologies play a pivotal role in the diagnosis and treatment design for CAD. Recently, in order to develop improved MPI agents for diagnosis of CAD, (99m)Tc-[...

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...

Technetium-99m dimercaptosuccinic acid (DMSA) scan was performed on a 32-year-old woman with 
 abdominal pain. A normal functioning slightly ptotic right kidney seen planar images. There no activity in the left renal region and small fusiform pelvic area. Pelvic computed tomography (CT) axial images revealed pre-vesical abscess pushing bladder posteriorly to side. On obtained after percuta...

Several radionuclides in a variety of chemical forms have been used for spleen scanning (1). None of these has as desirable physical properties as tech netium-99m, namely, the clean 140 keV gamma, absence of particulate radiation, and short physical half-life (2). As a result, it would be desirable to find a com pound of “9―Tc that could be used for spleen scanning. Technetium-99m sulfur co...

BACKGROUND Technetium-99m sestamibi scintigraphy has become one of the most popular techniques for localization of the parathyroid gland after failure of primary neck exploration. OBJECTIVE To examine the efficacy of sestamibi with the hand-held gamma ray detecting probe for the identification of parathyroid adenomas during revision parathyroidectomy. METHODS We reviewed six cases of probe-...

Diabetic foot infection is a heavily dreaded complication of diabetes, frequently leading to prolonged hospi-talisation, disability and amputation 1-3. It usually occurs in, mostly long-standing, foot ulcers and is difficult to diagnose and notoriously demanding to treat 1-5. Diagnosis rests on meticulous clinical examination to identify local and/or systemic symptoms of inflammation 1,6,7. How...

Uptake of technetium-99m methylene diphosphonate by the rectus abdominis muscle was unexpectedly found in a 29 year old man who had started to perform 30 to 40 sit ups a day for five days before the bone scan. After a week of rest, serum creatine kinase activity was still abnormal but muscle uptake of technetium-99m methylene diphosphonate had ceased. This specific muscle injury after short ter...

Extramedullary pulmonary hematopoiesis is a rare entity with a limited number of case reports in the available literature only. We report the case of a 66-year-old man with known primary myelofibrosis, in whom a Technetium-99m sulfur colloid bone marrow scan with single-photon emission computed tomography (SPECT)/CT revealed a pulmonary hematopoiesis as the cause of pulmonary hypertension and s...
