Normalization in quantitative [18F]FDG PET imaging: the ‘body surface area’ may be a volume

Abstract: Non-invasive methods for quantifying [(18)F]FDG uptake in tumours often require normalization to either body weight or body surface area (BSA), as a surrogate for [(18)F]FDG distribution volume (DV). Whereas three dimensions are involved in DV and weight (assuming that weight is proportional to volume), only two dimensions are obviously involved in BSA. However, a fractal geometry interpretation, related to an allometric scaling, suggests that the so-called 'body surface area' may stand for DV.

“…The effective exchange area in the internal structure of the body was linked to the so-called " fractal volume of drug distribution, " 123 which was recently associated with the body surface area used in dosage regimen design. 124 The clearance analog, called " fractal clearance, " was also defi ned 125 ; both novel parameters were used in quantitative structure pharmacokinetic relationships. [125][126][127] Additionally, the use of the scaling laws describing the fractal-like architecture of the arterial and venular trees enabled the development of a physiologically based model of 1-dimensional tube for the transport of materials in the circulatory system.…”

“…κλιμακώνεται αναλογικά με τη μάζα και αυτό επιβεβαιώνει τη θεωρητικά αναμενόμενη σχέση μεταξύ του όγκου και της μάζας των θηλαστικών ειδών (Karalis et al 2001). Η αποτελεσματική περιοχή ανταλλαγής στην εσωτερική δομή του σώματος συνδέεται με τον επονομαζόμενο «μορφοκλασματικό όγκο κατανομής του φαρμακομορίου» ("fractal volume of drug distribution"), ο οποίος έχει συσχετισθεί με την επιφάνεια του σώματος που χρησιμοποιείται για το σχεδιασμό της δοσολογικής μορφής (Laffon et al, 2006;Pereira, 2010) . Η σχετική με τα προαναφερθέντα έννοια της «μορφοκλασματικής κάθαρσης» έχει επίσης αναπτυχθεί (Karalis and Macheras, 2002).…”
