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-...

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...

Cervical spinal Ewing's sarcomas are rare and cause problems in diagnosis. We present an unusual case of a primary extraosseous Ewing's sarcoma arising from the spinal cord. An 18-year-old woman with fever, headache and back pain lasting one month was admitted to the hospital. Whole body bone scintigraphy was performed with 1110 MBq technetium-99m methylenediphosphonate. Scintigraphy clearly sh...
