1. DWMRI ADC Patient – Rhodes Four Exams

2. Rhodes 10 Contours 2 Lesions Exclusion Contour – Brain Stem

3. Rhodes Contours Contour 1 Contour 9

4. Rhodes DWMRI Contour 1 – Lesion 1 Contour 1 – Brain Stem

5. Rhodes DWMRI Contour 9 Lesion 2

6. Rhodes ADC Values

7. Rhodes Lesion 1 vs Brain Stem

8. Rhodes b=0 Intensity values

9. Rhodes Results No clear trends in lesions Large variation in Brain stem ADC

10. Rhodes Issues Not all Contours used – Treatment contours close slices – DWMRI slices larger spacing Large variation in b=0 intensity values – Does it affect ADC? – Is there a way to correct or determine baseline comparison?
