A gamma spectrometric analysis of rock samples collected from the Precambrian Oban Massif, southeastern Nigeria, was performed to determine some primordial radioelements’ activity concentrations: U-238, Th-232, and K-40, their associated radiological hazards. The mean radionuclides determined be 1073.06 ± 0.65, 160.74 1.32, 250.76 0.91 Bq·kg−1 for 40K, 238U, 232Th, respectively, showing that th...

The American College of Radiology has developed appropriateness criteria for a number of clinical conditions and procedures. Criteria are available on imaging tests used in the evaluation of acute chest pain--suspected myocardial ischemia. Imaging tests for a suspected cardiac etiology include transthoracic echocardiography, transesophageal echocardiography, radionuclide perfusion imaging, radi...

The objectives of the study are to examine radiation and health physics situation in area ship repair enterprises servicing ships with nuclear power installation; assess its possible impact on environment population. Materials research methods. territory was conducted by walking gamma survey using portable spectrometric complexes MKS-01A "Multirad-gamma" MKS-AT6101C. Gamma-spectrometric radioch...

In this study, 16O(p,α)13N nuclear reaction was chosen as the best method of N-13 production. High purity natural water targets were bombarded by 18 MeV protons with an intensity of 8μA. A production yield of 13.5 mCi/μAh was obtained. Chemical modification of 13N-nitrogen oxides into [13N]NH3 was accomplished using De Varda's catalyst. Chemical, radiochemical and radionuclide purity cont...

One of the most important roles of cardiovascular nuclear medicine in evaluating patients with coronary artery disease (CAD) is predicting patient outcome. Measurements of ventricular function obtained by radionuclide ventriculography play a key role in defining a patient's prognosis. Because ventricular function correlates well with the total extent of myocardial ischemic burden, data derived ...

Radionuclide cisternography is generally considered to be a safe procedure without significant neurological complications. However, in this report we present a patient who developed conus medullaris syndrome following radionuclide cisternography. A 46-year-old woman underwent lumbar puncture followed by radionuclide cisternography with the diagnosis of hydrocephalus. After the cisternography, s...
