Positron emission tomography/computerized tomography in the evaluation of primary non-Hodgkin’s lymphoma of prostate

Figure 1 Positron emission tomography/computerized tomography image. A: Whole body positron emission tomography (PET) image (scan) shows nodal hypermetabolic foci in the prostate, and no abnormally high uptake foci in the other sites of the body; B: The PET/computerized tomography (CT) fusion image displays a nodal hypermetabolic lesion located in the right lobe of the prostate, with maximal standardized uptake value (SUV) being 12.7; C: There were no hypermetabolic foci on the whole body PET imaging following six courses of chemotherapy; D: There was complete remission of the prostatic lesion after six cycles of chemotherapy, and the maximal SUV was 2.0.
