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...

when tc-99m-sulfur colloid was introduced as an ideal liver-spleen agent in nuclear medicine, many other types of colloids followed by different manufacturers. they hoped to find a suitable colloidal agent, contrary to sulfur colloid, which is easy to use, and less sensitive to the low contamination of aluminum ions. one of this type of colloid agents, is tc-99-tin-colloid which is prepared by ...

A 62-year-old patient presented with flatulence, abdominal distension and other symptoms of ileus. Roentgenographic finding found compression on duodenum. Blood pool scintigraphy ((99m)Tc erythrocytes) showed aortal aneurysm, while simultaneous gastric emptying study with liquid meal ((99m)Tc-S-colloid) showed dislocation of duodenum and compression from abdominal aortal aneurysm.

BACKGROUND The new trend in diagnosis of the lymph node is sentinel node biopsy. This method has become increasingly accepted as a minimally invasive alternative to routine axillary dissection. Although the results of numerous studies have shown that sentinel node biopsy can accurately determine the axillary nodal status, the identification rates and false-negative rates have been variable. The...

Poly[1,4,8,11-tetraazacyclotetradecane(2+) [hepta-mu-sulfido-trisulfidohexaantimony(III)]], {(C10H26N4)[Sb6S10]}n, consists of novel [Sb6S10]2- layers containing Sb2S2, Sb4S4 and Sb7S7 hetero-rings, which are separated by macrocyclic amine molecules. The macrocyclic amine molecules are disordered over two crystallographically distinct positions and are diprotonated in order to balance the charg...

Nanomaterials as anode for lithium-ion batteries (LIB) have gained widespread interest in the research community. However, scaling up and processibility are bottlenecks to further commercialization of these materials. Here, we report that bulk antimony sulfide with a size of 10-20 μm exhibits a high capacity and stable cycling of 800 mAh g(-1). Mechanical and chemical stabilities of the electro...

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...
