[en] Full text: Using national and international recommendation about human resource in nuclear medicine, a group of experts organized a national course for the education and training of physicist who works in Cuban hospital, adapted to national condition and practice of nuclear medicine. The program was approved for National Authorities in Nuclear Security and University School in Medicine and content three intensive theoretic and practical courses (15 days of full time duration each), complemented with 4 months full time in Nuclear Medicine Service monitored by accredited expert and 2 months at distance with practical task. The theoretical/practical intensive courses have final evaluation: combining practical exercise and write final test. When all docent activities finish the students should pass a final evaluation by a testing board composed for (at least) three accredited experts. The first theoretical/practical course included 19 physicists who work in hospital, the second 17 and the third 16 students. With 100 point of maximum score and 60 point minimum to pass, the partial final tests included: true or false choice (with 10 aspects to verify, 1 point/correct answer) and questions to write developed answer. The average result was 83.02 points/ students (range 65-100 points). The students evaluated satisfactory the quality of different courses (in anonymous poll), reporting like very good; the quality of conferences, excellent; the usefulness of different charters, very good; the support bibliography, and recommended the repetition of this kind of education and training in order to warranty the human resource, in the same way and content, and included others item in the future. Conclusion: the theoretical/practice intensive courses of this post-graduated course were successful and satisfied the objective of education and training of medical physicist in nuclear medicine.

[en] Human pharmacokinetics, biodistribution and internal radiation dosimetry to normal organs and total body of ^99m Tc-labeled monoclonal antibody ior egf/r³ was investigated following intravenous injection in 5 patients. Following administration, blood and urine samples were collected from 4 patients up to 24 hr after injection Pharmacokinetics obtained from whole blood radioactivity showed blood disappearance described most properly by a biexponential model with a mean distribution half-life value of 0.14±0.02 hr and elimination half-life value of 31.0±13.6 hr. Whole body anterior and posterior scans were obtained at 10 min, 1,3,5 and 24 hr after injection. ROIs were drawn over the heart, liver spleen and bladder to measure the activity in the source organs. Time-activity curves for each source organ were fitted to mono- or biexponential functions by non-linear least squares regression using the flexible polyhedral method and integrated to determine organ residence times. The mean absorbed dose to the whole body and various normal organs were then estimated from residence times and from blood and urine samples using the MIRD method. The effective dose equivalent (EDE) and effective dose (ED) were calculated. Estimates of radiation absorbed dose to normal organs in rads/mCi administered (mean ± SD, n=4) were: whole body, 0.0185± 0.0023, gallbladder wall, 0.0755± 0.00761, spleen, 0.0637± 0.0167 and liver, 0.276± 0.029. The effective dose equivalent and effective dose estimates for adults were 0.039± 0.008 and 0.028± 0.004 rem/m Ci administered. (author). 15 refs., 3 figs., 3 tabs
