A practical training program that enabled students to experience an aged person and hemiplegia patient was developed as part of the "Practice Program in Medical Imaging Technology," to help the students understand how to support patients in the X-ray examination setting. Eighty-three third-year radiological technology students participated in the program. During the hour-long course, they experienced a simulated program that contained various checkpoints. The students pointed out the difficulty patients had in going up and down stairs (51.8%) and their feelings of uneasiness and fear of blindness (36.1%). As a result of this practical training program, the students increased their understanding of how to support patients slated for X-ray examinations. However, certain problems became clear, such as students' insufficient experience and lack of practical guidance in supporting aged patients and those with hemiplegia at the time of X-ray examinations. This information will helpful for improving similar training programs to be held in the future.
Cerebral blood flow (ml/min/100g) (CBF) was detected by two methods, static xenon inhalation dynamic CT (Xe-CT) and perfusion CT, and a comparison of these two methods (Xe-CBF and perfusion CBF) was carried out in the same cases. Xe CT used 30% static xenon, 4 min wash-in, and 5 min wash-out, while perfusion CT was done by injecting 30 ml of non-ionic contrast medium at a rate of 9ml/sec. Forty-eight patients underwent these examinations (30 serious cases and 18 mild). The correlation coefficients in the hemispheric area were r=0.713 (p<0.01) with Xe-CBF and perfusion CBF in mild cases and r=0.567 (p<0.01) in serious cases. The two CBF values were especially disparate in serious cases. The value for perfusion CBF was almost double that of Xe-CBF in these cases. Perfusion CT was a useful examination for the detection of CBF, but in serious cases, CBF needs to be determined by Xe-CT as well.
