The 27th Report on Survey of the Adverse Reaction to Radiopharmaceuticals (the 30th survey in 2004)

This survey was performed in order to investigate the incidence of adverse reactions to radiopharmaceuticals and defect products in FY2004 in Japan. It was based on responses to questionnaires sent to nuclear medicine institutions. The reply was obtained from 968 institutions among 1,220 to which the questionnaire had been sent. Sixteen cases of adverse reactions were reported. A total of 1,277,906 radiopharmaceutical administrations was reported. The incidence of adverse reactions per 100,000 cases was 1.3. Eight cases of defect products were reported, and the incidence of defect products per 100,000 cases was 0.6.

Twenty-two cases of adverse reactions were reported. A total of 1,046,243 radiopharmaceutical administrations was reported. The incidence of adverse reactions per 100,000 cases was 2.1. One case of defect products was reported, and the incidence of defect products per 100,000 cases was 0.1.     

Report based on fiscal 2000 diagnostic x-ray equipment questionnaire survey(conditions of radiography)

X-ray equipment has seen advances in inverters and the digitalization of reception systems. The X-ray Systems Study Group, in order to examine changes in the conditions of radiography, including pediatric radiography, variations in shortest irradiation time, and standardization of the conditions of radiography, carried out investigative research using a questionnaire survey that was sent to 400 facilities. The recovery rate was 33%. In terms of the reception system, half of the general radiography systems were using computed radiography (CR). Seventy percent of respondents used an intensifying screen and film(S EF)in stomach double-contrast radiography. About 80% used digital radiography (DR) and digital subtraction angiography (DSA) in aorta abdominalis angiography. At least 70% of high-voltage generators were of the inverter type. The conditions of radiography were not greatly influenced by changes in reception systems and X-ray equipment. Many pediatric radiographies were carried out by radiological technologists. We consider it useful to conduct such survey investigations.     

The 28th report on survey of the adverse reaction to radiopharmaceuticals (the 31st survey in 2005)

This survey was performed in order to investigate the incidence of adverse reactions to radiopharmaceuticals in FY2005 in Japan. It was based on responses to questionnaires sent to nuclear medicine institutions. The reply was obtained from 1,007 institutions among 1,243 to which the questionnaire had been sent. Nineteen cases of adverse reactions were reported. A total of 1,264,098 radiopharmaceutical administrations was reported. The incidence of adverse reactions per 100,000 cases was 1.5. Three cases of defect products were reported, and the incidence of defect products per 100,000 cases was 0.2.     

Report based on Fiscal 2000 Diagnostic X-ray Equipment Questionnaire Survey (conditions of X-ray units and similar equipment)

The X-ray Systems Study Group, in an attempt to determine the current status and changes in the state of X-ray equipment, reception systems, and equipment control, conducted investigational research by distributing a questionnaire survey to 400 facilities. The rate of recovery was 33%. The capacity of transformers has been increasing in spite of the three-phase 415 V decrease in the power supply of X-ray equipment. Among high-voltage generators, inverter-type X-ray equipment accounted for 81.3% of units. The ratio of the X-ray tube of a conventional rotational system to that of a high-speed rotational system was 1:3, and 54.9% had target angles of 12 . Many X-ray tubes had a heat capacity of less than 200-300 kHU. The body parts that had the shortest times on radiography were adult chest and pediatric chest. In many cases, the shortest time used was 10 msec. Facilities in which the shortest time was less than 10 msec accounted for almost half of the total number. Facilities where the radiation dose of radiography had decreased showed 1/4 of the digitalization whole. Measurement was carried out when the equipment was bought in 94.9% of facilities, and measurement when the service contract was finished was done in 77.1% of the responding facilities.

The reliability of balance tests performed on the kinesthetic ability trainer (KAT 2000)

The Kinesthetic Ability Trainer (KAT 2000) is a balance platform designed for training and functional testing of the neuromuscular control system. Forty healthy and sports-active persons were tested and 1 month later retested to investigate the reliability of the KAT 2000 testing “one-leg static balance” and “two-leg dynamic balance”. A significant improvement at retesting on the same day was seen in both tests; furthermore the dynamic test result improved significantly with retesting 1 month later. The data obtained made it possible to calculate the 95% confidence limits for an unchanged test result for a single person and a group of persons. The results show a clear learning effect when the persons are retested, especially in the dynamic test. The KAT 2000 can be used as a tool for testing groups of persons both in short- and long-term studies, but it cannot be used for testing single persons due to the great variance in the test results. Further investigations involving injured persons are needed to determine the range of improvement after intervention. Received: 19 April 1999/Accepted: 25 November 1999     

Report on the 13th European Congress of Radiology (ECR): Comparison of primary proton beams and secondary charged-particles

PURPOSE: In the proton radiotherapy, primary proton beams contribute to the absorbed dose and the share of secondary charged-particles is small. The purpose is to discuss about the ratio of average dose of primary proton beams and secondary charged-particles. METHODS: We performed the dosimetry of 70 MeV proton beams in water using ionization chamber. The ratio of average dose for secondary charged-particles in some range shifter was calculated by the dose ratio of primary and scatter. To exclude the influence of lateral secondary charged-particles, the ratio of average dose for secondary charged-particles was extrapolated to zero field size of each. RESULTS: The ratio of average dose for secondary charged-particles was extrapolated to zero field size by the bi-exponential fit. The ratio of average dose for longitudinal secondary charged-particles for zero fields at each depth is almost the same; the different at the shallow depth is decreased. CONCLUSIONS: The secondary charged-particles from collimator is affected by the dose of shallow depth. The influence of lateral secondary charged-particles in water phantom was excluded with the extrapolation method for zero field size in each depth.
