Comparisons of Adjusted Positioning in CT Gastrography

Purpose We classified three groups with position change from effection of bubble by using effervescent granules in CT gastrography. We compared the CT gastrography images with 3D reconstruction of the stomach and evaluated an effect to stomach tube image clinically. Materials and Methods In 90 adults (M:F=67:23, mean age; 59years) were performed. Before scanning, 8 g of effervescent granules with a small amount of vvater is administered orally to distend the stomach. CT gastrography is three groups: group I is only spine. roup II is Adjusted supine. groub III is prone, supine and LPO position. Ionic contrast material injection(150ml) was administered at a rate of 3ml/sec by a power injector for better reproducibility in follow-up examinations. We were taken a axial images(0.7mm) using the Siemens Somatom sensation 16(Erlangen, Germany) MIXT and then transmited the data GE workstation(AW4.1_06). We performed of 3 types randering method (Transparent Image, shaded surface display, virtual Endoscopy) using the Image quality grading method:(many, small, nil) Results The Results obtained as followed: group I Quantity of bubble (many=13, small=9, nil=8) group II Quantity of bubble (many=3, small=4, nil=23) group III Quantity of bubble (many=1, small=7, nil=22) Conclusion CT gastrography showed bubble using effervescent granules. group I got the image where the bubble is many, the group II, III got the image quality which is excellent. From the results of these studies, We were taken the best Image quality of all types post processing method in group III. group III for CT gastrography guaranteed the excellent 3D CT gastrographic images.
