Table CID 85. SUV Units

Coding Scheme Designator | Code Value | Code Meaning
--- | --- | ---
UCUM | g/ml{SUVbw} | Standardized Uptake Value body weight
UCUM | g/ml{SUVlbm} | Standardized Uptake Value lean body mass (James)
UCUM | g/ml{SUVlbm(James128)} | Standardized Uptake Value lean body mass (James 128 multiplier)
UCUM | g/ml{SUVlbm(Janma)} | Standardized Uptake Value lean body mass (Janma)
UCUM | cm2/ml{SUVbsa} | Standardized Uptake Value body surface area
UCUM | g/ml{SUVibw} | Standardized Uptake Value ideal body weight

### Note

The formulas for the determination of SUVbw, SUVbsa, SUVlbm (James) and SUVibw are defined in Sugawara et al. Reevaluation of the Standardized Uptake Value for FDG: Variations with Body Weight and Methods for Correction.Radiology, 1999 at http://radiology.rsna.org/content/213/2/521.

Unfortunately, Sugawara used a parameter of 120 rather than 128 for males, propagating an error in Morgan DJ, Bray KM. Lean Body Mass as a Predictor of Drug Dosage: Implications for Drug Therapy. Clinical Pharmacokinetics. 1994;26(4):292–307, which misquoted the original LBM definition that used 128 in James WPT, Waterlow JC. Research on Obesity: A Report of the DHSS/MRC Group. London: Her Majesty’s Stationery Office; 1976. Implementations differ in whether they have used 120 or 128 for ({SUVlbm}g/ml{SUVlbm}, UCUM, "Standardized Uptake Value lean body mass (James)"). See Kelly M. SUV: Advancing Comparability and Accuracy. Siemens; 2009. Available from: http://www.mpcphysics.com/documents/SUV_Whitepaper_Final_11.17.09_59807428_2.pdf.

The Janmahasatian LBM formula is defined in Janmahasatian et al. Quantification of Lean Bodyweight. Clin Pharmacokinet. 2005 Oct 1;44(10):1051–65. at http://dx.doi.org/10.2165/00003088-200544100-00004 and its role in SUVlbm(Janma) calculation is discussed in Tahari et al. Optimum Lean Body Formulation for Correction of Standardized Uptake Value in PET Imaging. Journal of Nuclear Medicine. 2014 Sep 1;55(9):1481–4. at http://jnm.snmjournals.org/content/55/9/1481. The patient size correction factors are summarized here, where weight is in kg and height is in cm:

SUVbw: males & females: weight

SUVlbm (James): males : 1.10 * weight - 120 * (weight/height) ^2

SUVlbm (James): females: 1.07 * weight - 148 * (weight/height) ^2

SUVlbm(Janma): males: 9.27E3 * weight / (6.68E3 + 216 * weight / (height^2))

SUVlbm(Janma): females: 9.27E3 * weight / (8.78E3 + 244 * weight / (height^2))

SUVbsa: males & females: weight^ 0.425 * height^0.725 * 0.007184

SUVibw: males: 48.0 + 1.06 * (height - 152)

females: 45.5 + 0.91 * (height - 152)
