Workstation을 이용한 CT, MR, TFCA 3D image의 비교 분석

Compared analysis of the CT, MRI, TFCA image using the workstation

Purpose We compared cerebral aneurysm image of confirmed patients using workstation and evaluated the predominance among 3D-MDCT, 3D-MRI, 3D-TFCA for the modality. Materials and Methods During June 2004 to January 2005 we examined 43 patients suspected for cerebral subarachnoid hemorrage of 75 patients(male : female = 22 : 53, everage age = 57) tested TFCA in 320 patients tested MDCTA, MRA at Eulgi university hospital.(9 patients tested MDCTA, MRA, TFCA and 29 patients tested CTA, TFCA and 5 patients tested MRA, TFCA) So we compared image of true aneurysm, junctional dilatation in 3D-MDCT, 3D-MRI, 3D-TFCA with 2 professor by 3D Workstation Rapidia(Infinitt Korea), Siemens Inspace software and Munich Germany. Results As a result of cerebral aneurysm 3D image from MDCTA, MRA, TFCA, it was confirmed for 22 true aneurysm patients, misrecognized for aneurysm 7 junctional dilatation patients among 29 patients tested TFCA after MDCTA and 3 true aneurysm patients, misrecognized for aneurysm 2 junctional dilatation patients among 5 patients tested TFCA after MRA and misrecognized for aneurysm patients tested TFCA after MRA and and misrecognized for aneurysm 1 junctional dilatation patient tested MDCTA after MRA. We got the same result, controled 3D threshold and reconstructed 3D again, of 3 patients among 7 patients confirmed for junctional dilatation tested TFCA after MDCT A like the result of TFCA. Conclusions We could not satisfactionally get the result, controled 3D threshold and reconstructed 3D again, of misrecognized for aneurysm 2 patients in MRA than the result in MDCTA. MRA 3D image was became to express uncertain portion more certainly than MRI MIP image. From the result of compared 3D image we could find the aneurysm and a high diagnosis value in TFCA first of all and the second in MDCT A and the last in MRA. It was expressed more certainly in MRA 3D image than in MRI MIP image.
