From: In vivo quantification of neurofibrillary tangles with [18F]MK-6240
Comparisons between different quantification methods for [18F]MK-6240. Scatter plots show regressions performed across individuals and brain regions between (a) Logan model vs reversible two-tissue comportment model with four parameters (2T-CM4k), (b) reference Logan model vs 2T-CM4k, (c) simplified reference tissue model (SRTM) vs 2T-CM4k, (d) SUVR90–110 vs reference Logan model, and (e) SUVR90–110 vs SRTM. (a–c) Individuals who underwent arterial blood sampling. (d, e) All participants. DVR distribution volume ratio
