MRI Diffusion-weighted imaging Carotid intraplaque haemorrhage Cervical artery dissection Intramural hematoma ADC
摘要：

To assess the difference between carotid haemorrhagic plaque and non-haemorrhagic plaque by using diffusion-weighted imaging (DWI) and to evaluate carotid intraplaque haemorrhage (IPH) and intramural hematoma (IMH) of cervical artery dissection with apparent diffusion coefficient (ADC) measurement. Fifty-one symptomatic patients underwent 3.0-T carotid MR imaging, including conventional sequences, three-dimensional (3D) magnetization-prepared rapid acquisition gradient-echo (MPRAGE) sequence, and DWI. Thirty-nine patients with carotid plaque and eight patients with IMH of cervical artery dissection were finally included. The groups of hemorrhagic plaque, non-hemorrhagic plaque and IMH were divided according to 3D MPRAGE sequence. ADC values of different groups were measured, and t tests were performed. The mean ADC values of hemorrhagic plaques, non-hemorrhagic plaque and IMH were (1.284 +/- 0.327) x 10(-3)mm(2)/s, (1.766 +/- 0.477) x 10(-3)mm(2)/s, and (0.563 +/- 0.119) x 10(-3)mm(2)/s, respectively. The mean ADC values of hemorrhagic and non-hemorrhagic regions in the hemorrhagic plaque group were (0.985 +/- 0.376) x 10(-3)mm(2)/s and (1.480 +/- 0.465) x 10(-3)mm(2)/s, respectively. The differences between the hemorrhagic plaque and non-hemorrhagic plaque, hemorrhagic region and non-hemorrhagic region in hemorrhagic plaque, and the hemorrhagic region in the hemorrhagic plaque and IMH of artery dissection were significant (P < 0.05). DWI may be a useful complement to conventional MR imaging for identifying haemorrhage of carotid plaques and differentiate IMHs from IPH. aEuro cent ADC values of IPH are lower than the plaque without IPH. aEuro cent DWI might be a useful complement to identify IPH. aEuro cent IMH may be differentiated from IPH by using DWI.
