From: CT-free quantitative SPECT for automatic evaluation of %thyroid uptake based on deep-learning
%thyroid uptake between CT-free SPECT and SPECT/CT as an external verification test (n = 29 salivary SPECT/CT). a The correlation is excellent with r = 0.9959, R2 = 0.9918, and p < 0.0001. b The Bland–Altman plot shows mild deviation (greater %thyroid uptake by CT-free SPECT) with bias = 0.106% point. c %thyroid uptakes between CT-free SPECT and SPECT/CT were similar in various salivary diseases. The normal reference range of %thyroid uptake was reported as 0.78 ± 0.5% [21]
