NGSE-Corr: A technique for objective clinical evaluation of quantitative-imaging methods without a gold standard

Yan Liu, Ziping Liu, Zekun Li +4

Objective evaluation of quantitative-imaging (QI) methods based on how reliably they measure true values is important for clinical translation. Performing such evaluation with pati…

Development and in silico imaging trial evaluation of a deep-learning-based transmission-less attenuation compensation method for DaT SPECT

Zitong Yu, Md Ashequr Rahman, Zekun Li +7

Quantitative measures of dopamine transporter (DaT) uptake in caudate, putamen, and globus pallidus derived from DaT-single-photon emission computed tomography (SPECT) images are b…

WIN-PDQ: A Wiener-estimator-based projection-domain quantitative SPECT method that accounts for intra-regional uptake heterogeneity

Zekun Li, Nadia Benabdallah, Daniel L. J. Thorek +1

SPECT can enable the quantification of activity uptake in lesions and at-risk organs in α-particle-emitting radiopharmaceutical therapies (α-RPTs). But this quantification is chall…

A list-mode multi-energy window low-count SPECT reconstruction method for isotopes with multiple emission peaks

Md Ashequr Rahman, Zekun Li, Zitong Yu +3

SPECT provides a mechanism to perform absorbed-dose quantification tasks for -particle radiopharmaceutical therapies (-RPTs). However, quantitative SPECT for -RPT is chall…

Joint regional uptake quantification of Thorium-227 and Radium-223 using a multiple-energy-window projection-domain quantitative SPECT method

Zekun Li, Nadia Benabdallah, Richard Laforest +3

Thorium-227-based alpha-particle radiopharmaceutical therapies (α-RPTs) are being investigated in several clinical and pre-clinical studies. After administration, Thorium-227 decay…

No-gold-standard evaluation of quantitative imaging methods in the presence of correlated noise

Ziping Liu, Zekun Li, Joyce C. Mhlanga +2

Objective evaluation of quantitative imaging (QI) methods with patient data is highly desirable, but is hindered by the lack or unreliability of an available gold standard. To addr…
