A randomized controlled trial titled "Quantifying Pancreatic Fat Using a Free-Breathing Acquisition in Adults With Obesity Undergoing Diet-Induced Weight Loss-Results From the LION Study" appears in NMR in Biomedicine. The trial is listed on PubMed and ClinicalTrials.gov [^1].

The study enrolled 18 participants and ran for 3 months.

Authors reported that compared to Cartesian scans, radial scans exhibited a minor positive volume bias at higher pancreatic volumes. Linear regression for volume was 0.85x + 9.4 cm³. Mean volume bias was 5.8 cm³, with 95% limits of agreement from -7.1 to 18.7 cm³.

A proportional PDFF bias was also observed. This bias led to slight overestimation at lower values and underestimation at higher values. Linear regression for PDFF was 0.88x + 2.1%. Mean PDFF bias was -0.2%.

Funding was provided by the German Federal Ministry of Education and Research and the German Research Foundation.
