Figure 4

Head neck tumour, normal injected activity. The improvement of image quality can be easily seen for a patient examined by [11C]-Acetate. Large images display filtered data using principal components 1–4 (83% explained variance), and inserts show original data. The transition of acetate uptake from blood to tissue can be followed in A), only blood, B) blood and metastases uptake, C) only metastases uptake.
