MR Angiography of the Head/Neck Vascular System in Mice on a Clinical MRI System
Figure 5
Interobserver agreements of non-contrast-enhanced and contrast-enhanced MR angiography. Interobserver correlation for area measurements in the non-contrast-enhanced MR angiography (TOF) showed a close correlation between both image readers (R2 = 0.81; ). The associated 95% confidence interval (CI) for the correlation range was −0.73 to 0.89. Interobserver correlation for area measurements for the contrast-enhanced MR angiography (GdT) showed a stronger correlation between both readers (R2 = 0.94; ). The associated 95% confidence interval (CI) for the correlation range was −0.42 to 0.43 (Figure 5).
