- ROI using maximum pixel is useful tool in image quantification :
- Convenient : for drawing ROI on small lesions.
- Accurate : for calculating counts/pixel (activity concentration).
- Reproducible : multi-users achieve the same results.
- The corrected SUV for the partial volume effect of diameter of 10.6,
14.4, 16.9, 20.6, 28.1 and 39.4 mm was almost 4.2, 3.0, 2.2, 1.6, 1.2,
and 1.04 times higher, respectively, than the uncorrected SUV.
- The diagnostic sensitivity was increased from 54% to 85% with the
- Recovery coefficient of the partial volume effect may be applicable for
lesions size of less than 40mm in diameter.
