ABSTRACT
Objective To evaluate the display ability and the clinical application of multislice spiral CT virtual endoscopy (CTVE) in the diagnosis of vascular diseases. Methods Fifty-six patients were examined by CT virtual endoscopy.32 patients also had DSA for comparison.18 patients were confirmed by operation (3 patients also had DSA).9 patients with pulmonary embolism were confirmed by other examinations and treatments.Results 56 patients showed successful CT virtual endoscopy images.CT virtual endoscopy images could clearly show the inner wall and inner structures of the vessels,mural thrombus,calcification form,stenosis of the vessels,the true and false lumina of aortic dissections,the lesion of false aneurysm,and the anatomic relationship between the lesion and surrounding structures of the normal vessels.Out of the 32 patients with vessel abnormalities on DSA,24 patients (75%) showed the lesions on CTVE.17 out of 18 patients with operation showed the lesions on CTVE.All 9 patients with pulmonary embolism showed the abnormalities on CTVE.Chi-square test? 2=5.2809,P=0.071 patients showed the vascular diseases on CTVE in 56 patients (84%).Conclusion MSCT virtual endoscopy could provide more information of the vessel by displaying the inner wall and allowing users to map the vessels in a display.It is helpful in correct diagnosis and guiding surgery.
