Diagnostic Value of the Change of Signal Intensity at the Jugular Bulb in Sigmoid Sinus Thrombosis / 实用放射学杂志

ABSTRACT

Objective To study the value of the changes of signal intensity at the jugular bulb in diagnosing sigmoid sinus thrombosis.Methods MR imaging examinations were performed in 27 cases with cerebral venous sinus thrombosis(transverse and sigmoid sinuses).The signal intensity at the jugular bulb was evaluated in comparison with that in 20 healthy persons,and the results were dealed with Wilcoxon rank sum test statistically.Results In sigmoid sinus thrombosis,the signal intensity at ipsilateral jugular bulb was higher than that in healthy group(P
