Figure 6

Parametric image. A) Patlak slope image of liver metastases using [18F]-FDG calculated employing original dynamic data. B) histogram of pixels in the liver for image A. C) Patlak slope image of the same data preprocessed by the Hotelling filter (PC 1–6) prior to Patlak calculations. D) histogram of pixels in the liver for image C, which displays a more narrow distribution than for the non-filtered data.
