Fig. 2

Cases with primary suspicious lesion type (A) liver cancer, (B) mediastinal lesion, and (C) lung cancer. The 60-min regular static images cannot confidently rule out the uptake foci (red arrows) from the background. They appear clear in delayed images and further in MRFDG images. For a lung lesion (D), the visual detectability among protocols was similar. Distribution volume images are shown in the last column
