RESUMO
Objective To explore the improvement effect of SLOT Scan technology (narrow seam exposure capture technology) and the radiography techniques on the quality of the scoliosis X-ray films in teenagers. Methods The Sonialvision Satire Ⅱ equipment of Shimadzu corporation and SLOT Scan were applied to take the radiography for 60 patients taller than 1.50 metres. All the data were collected through a continual exposure, and the images were sewn up through a seamless connec-tion software. Results Cervical, thoracic, and lumbar and sacral segments could clearly present at the same time on one X-ray film by seamless splicing, and the quality of one time radiograph was as good as one film. Conclusion As a new radiology technique, SLOT Scan can wipe off splitting arti-fact effectively and make the whole spine seamless present on one X-ray film. It helps the spinal sur-geons to observe, calculate and measure accurately. It is useful to choose the operation mode and judge the curative effect.
RESUMO
Objective To investigate the significance of administration of ionic contrast media with dexamethasone in preventing side effect during enhanced CT scanning. Methods We prospectively studied 520 patients who had enhanced CT scans and divided them into two groups: 259 patients received ionic contrast medium with dexamethasone (dexamethasone group); 261 patients received ionic contrast medium without dexamethasone (contrpl group). The side effects of the patients in two groups with different ages were compared. Results There were 19 patients with side effects in dexamethasone group (7 3%), 20 patients with side effect in control group(7 7%). The side effect rate in those patients over the aged 20 years and under the aged 60 years was higher than other age groups. The side effect rate was similar between dexamethasone group and control grouop.Conclusion Administration of Ionic contrast media with dexamethasone during CT scanning can not obviously decrease the incidence of side effect.
