Area of Science:

Radiology
Neuroimaging
Vascular Imaging

Background:

Carotid-cavernous fistulas (CCF) are abnormal vascular shunts.
CCF can lead to diverse neurological and orbital symptoms.

Purpose of the Study:

Evaluate the diagnostic performance of thin-section MR imaging for CCF.
Identify imaging predictors of CCF.

Main Methods:

Retrospective study of 98 patients with suspected CCF.
Compared thin-section MR imaging (3mm T1/T2WI, 0.6mm 3D CE-T1WI) with DSA.
Used univariate logistic regression to find imaging predictors.

Main Results:

DSA confirmed CCF in 38 of 98 patients.
Thin-section MR imaging showed 88.8% accuracy, 97.4% sensitivity, and 83.3% specificity.
Predictors included abnormal cavernous sinus contour, internal signal void, prominent venous drainage, and orbital swelling.

Conclusions:

Thin-section MR imaging offers high diagnostic performance for CCF.
Identified imaging predictors can aid diagnosis.
MR imaging protocols can guide patient management.
