Cyclotron Produced Isotopes for Medical Applications

Cyclotron produced isotopes for medical use are classifiable as single photon emitters (201Tl, 123J, ~7Ga), used for planar and tomographic imaging (=SPECT), and as positron emitters (l8F, l~O, 13N, llC) as applied for tomographic organ imaging (=PET). There is a number of generator produced positron emitters. This paper reviews the application in clinical nuclear medicine for cardiology (myoca...

Distribution of lead-203 in human peripheral blood in vitro.

In-vitro experiments using 203Pb were performed to identify the lead binding components in human peripheral blood. The distribution of lead in plasma, in the red cell membrane, and within the red cell was also investigated. Studies of the distribution of 203Pb in whole blood showed that at a lead concentration of 2.45 mumol/l (50 micrograms/100 ml) about 94% of lead had been incorporated by the...

Magnetic deflector for mesons produced in the 184-inch cyclotron.

Evaluation of mass-produced lead tungstate crystals

Because of broad interest in high-energy and nuclear physics community, mass production capacities of lead tungstate (PWO) crystals have been established. The optical and scintillation properties of PWO crystals, 20 each from two major vendors, were evaluated. The transmittance, emission and excitation spectrum, light output, decay kinetics and light response uniformity, as well as their degrad...

203 Ngoan

From 1956-70 among 6,668 female cancers, 3,023 cases (45% of female cancers) were cervical cancer reported by medical institutions in Ho Chi Minh City (HCM), south Viet Nam, (Hoanh et al., 1976). Thereafter, from 1976-81, a very high frequency of cervical cancer was also reported: 53% of the female cancer patients (3,602 of 6,757 cases) treated in the Central Oncology of Ho Chi Minh City, (Truo...
