[Abstract] Objective: To study the comparison of 2D-TOF MRA and 3D-CE MRA in intracranial venous sinus, comparing the advantages and disadvantages of two kinds of scanning method.Materials and Methods: In our hospital between October 2013 and March 2014, we randomly selected 100 cases intracranial venous blood vessel imaging (at the same time using 2D-TOF MRA with 3D-CE MRA) through analyzing the patients. We comprehensively evaluate the ability of 2D-TOF MRA technology and 3D-CE MRA technology on the display of intracranial venous sinus in order to correctly select a method of intracranial venous sinus to get better display effect. Selection criteria: 1 to display the intracranial venous sinus shape better, and the connection way of torcular region. 2 to display the intracranial venous sinus lesions better, reflect the application value in the intracranial lesions. 3 to considerate the patient's own conditions and economic conditions, choose the appropriate scanning method.Results: 2D-TOF MRA can clearly show the intracranial venous sinus 50 cases, and the other 50 cases were failed to be showed clearly. 3D-CE MRA can clearly show 84 cases, fail to show clearly 16 cases, comparison between 2D-TOF MRA and 3D-CE MRA has statistical significance (χ2= 26.142, P=0.001). The accuracy rate of 2D-TOF MRA in the diagnosis of intracranial venous sinus disease was 88% (88/100), the sensitivity was 66.7% (16/24) and specificity was 94.7% (72/76), positive predictive value and negative predictive values were 80% (16/20), 90% (72/80). The accuracy rate of 3D-CE MRA in the diagnosis of intracranial venous sinus disease was 92% (92/100), the sensitivity was 75% (18/24) and the specificity was 97.4% (74/76), positive predictive value and negative predictive value were 81.8% (18/22), 92.5% (74/80).Conclusions: 3D-CE MRA was able to clearly display and diagnose intracranial venous sinus, and better than 2D-TOF MRA in the transverse sinus and sigmoid sinus display, but the use of comtrast agents in 3D-CE MRA makes its risks and costs increase.
