ABSTRACT
Objective To study clinical application value of 128-slice spiral CT imaging post-processing technique in knee joint trauma.Methods 75 cases of knee traumatic patients were examined by ordinary X-ray and 128-slice spiral CT imaging post-process-ing technique,and retrospectively analysed.Results For 75 cases of knee trauma patients,on X-ray examination 64 cases of fracture patients(78 fractures),6 patients of possible fractures,5 cases of missed diagnosis and misdiagnosis in were found,the detection rate was 88.6%;all patients underwent 128-slice spiral CT imaging post-processing technique-MPR/VR,and definite diagnosis of knee joint bone fracture was found in 75 cases (88 fractures),the detection rate was 100.0%,which was significantly higher than that on the X-ray examination (χ2 =6.1 1 7 2,P <0.05).The MPR reconstruction of knee joint fracture is of the highest detection rate.Con-clusion MSCT imaging post-processing technique can directly,clearly and comprehensive display knee joint trauma cases,and help doctors understand the relationship between fractures,soft tissue and joint space,in order to develop accurate and reasonable clinical treatment plan.
ABSTRACT
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.
ABSTRACT
Objective To investigate the application of computed radiography(CR) in X-ray projection of whole lower limbs.Methods The radiography in the patient with bilateral knee-malformation was performed using 500 mA X-ray apparatus and several imaging plates(IP) jointed together,then the images including whole both sides of lower limbs were obtained by post-proccesing technique.Results The images not only could show the whole lower limbs on a single film,but be intact.The images also could be used for measuring the length of leg,the angle between the axises of the thigh and the magnifying really.Conclusion The image of whole bilateral lower limbs with a good quality and unity can be acquired using CR and post-processing technique appropriately.
