Incremental Value of Plaque Enhancement in Patients with Moderate or Severe Basilar Artery Stenosis: 3.0 T High-Resolution Magnetic Resonance Study

Table 2

Morphology analysis of basilar artery stenosis.

	Asymptomatic; () (%)	Symptomatic; () (%)
Eccentric plaque	91.7 (22)	78.8 (26)	0.277
Focal thickening	95.8 (23)	84.8 (28)	0.384
IPH	33.3 (8)	42.4 (14)	0.486
Enhancement	45.8 (11)	81.8 (27)	0.004
Severe stenosis	37.5 (9)	33.3 (11)	0.745

IPH: intraplaque hemorrhage. Enhancement is a combination of grade 2 and grade 3.
