**2. Scintimetric characterization**

The scintillations in a focal hot spot can be counted using Scintimetry. Depending upon the method of comparison there are TWO types of Scintimetry:


### **2.1 Regional scintimetry methods**

Scintimetric evaluations can be performed with several quantitative approaches. Some of the most popular methods are: a. Local Uptake; b. bone soft tissue ratio; c. Lesion bone ratio; d. Standardized Uptake Ratio (SUV); and e. Percentage uptake.
