Working image

A further quantitative improvement over the previous imaging work was due to the discovery that the intense central feature of many of the... 

Fig. 18. (a) Representation of the tumor hypoxic state (diagram adapted from Ref. (83a). Arrow direction indicates decrease in pC>2 (< 1 mmHg), achieved for tumor depths larger than 100 pm (b) proposed mechanism for redox-mediated retention of [Cu(ATSM)] in hypoxic cells (101-105). Note Contrary to common belief cell membrane crossing solely by direct diffusion is unlikely for compounds of this family is unlikely, as indicated by fluorescence imaging work on aromatic Zn(II) analogs (vide infra). Endocytosis is the more likely uptake mechanism (112-113). 

The latest imaging work in high field gradients, however, has shown that broad lines may be imaged easily even for solids, so that imaging of 14N should no longer be a problem despite the short values for T2.

Although PEPT is likely to remain the more appropriate choice for most industrially oriented positron-imaging work, PET can be useful in some circumstances, particularly for following slow processes such as diffusion and some classes of diffusion/reaction problems, as well as multi-phase pipeline flow. 

The imaging work-up should be guided by a clinical assessment of the lesion level.
