The application value of MSCT in the diagnosis of carotid cavernous fistula / 实用放射学杂志

ABSTRACT

Objective To evaluate the application value of MSCT in the diagnosis of carotid cavernous fistula(CCF).Methods The data of 10 patients who had been confirmed with CCF by DSA were retrospectively analyzed to compare the imaging features of MSCT plain scan,CTA,post reconstruction imaging and other examination ways.Results 10 patients with CCF which were manifested by superior ophthalmic vein enlargement in CT plain scan,early appearance of superior ophthalmic vein and cavernous sinus enlargement in CTA were studied.The orificium fistulae can be displayed through the multi planar reconstruction (MPR)and the curved planar reconstruction (CPR).The focal region can be well displayed through the volume rendering (VR)and the maximum intensity projection (MIP). CT,MRI,DSA and color doppler ultrasonography have both advantages and limitations in the diagnosis of CCF.Conclusion MSCT can achieve characteristic imaging findings through scan,CTA technology and various post reconstruction methods,it has significant value in the early diagnosis and treatment of CCF.
