+#### SUVR
+
+**SUVR** stands for *Standardized Uptake Value Ratio*.
+
+The SUVR is the ratio of the image-derived radioactivity concentration
+ and the whole body concentration of the injected radioactivity. When SUVR > 1,
+it indicates radioactivity accumulation in that region above the hypothetical
+even radioactivity distribution.
