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

Figure 4

Plaque enhancement was graded by grade 0, grade 1, and grade 2. Grade 0 indicates no enhancement of plaque; grade 1 indicates that enhancement of plaque was less than the pituitary; grade 2 indicates that enhancement of plaque was similar to or greater than the pituitary.
