Comparative study on transcranial color duplex sonography and angiography in detection of cerebral arterial stenosis / 临床神经病学杂志

ABSTRACT

Objective To evaluate the reliability of transcranial color duplex sonography(TCCD) in the detection of stenosis of the middle cerebral artery(MCA).Method 168 patients with cerebrovascular di sease were underwent both cerebral angiography and TCCD examination.Result 18 stenosis of the MCA were diagnosed by angiography, 15 of the 18 stenosis were detected by TCCD. But 2 MCA stenosis diagnosed by TCCD were not proved by angiography. TCCD diagnosed MCA stenosis with sensitivity(83%) and specificity(88%) respectively.Conclusion MCA stenosis diagnosed by TCCD was better than by transcranial Doppler(TCD).
