Fig. 7From: Tc-HDP quantitative SPECT/CT in transthyretin cardiac amyloid and the development of a reference interval for myocardial uptake in the non-affected populationDistribution of corrected whole heart SUVmax for individuals without ATTR cardiac amyloid with the upper limits of 99% reference levels and their associated 90% confidence intervals marked. The dashed horizontal line represents the reference level determined by the robust method, the solid line the reference level determined assuming a normal distribution, and the dotted line is the meanBack to article page
