Qualitative Analysis of FLAIR MRI Findings in Different Anatomic Regions

Note.-FLAIR = fluid attenuated inversion recovery, CS = centrum semiovales, PT = pulvinar thalami, GP = globus pallidus, P = putamen, SN = substantia nigra, RN = red nuclei, DN = dentate nuclei

Grade: -2 = only 1.5T FLAIR images had three MRI findings (high signal intensity of CS; low signal intensity of PT; low signal intensity of iron deposit structures), -1 = 1.5T FLAIR images had more increased conspicuity of three MRI findings than did 3.0T, 0 = non-visualization of three MRI findings in FLAIR images, 1 = 3.0T FLAIR images had more increased conspicuity of three MRI findings than did 1.5T, 2 = only 3.0T FLAIR images had three MRI findings, 3 = same pattern of three MRI findings on both FLAIR images
