Erratum to: Point‐of‐care magnetic resonance technology to measure liver fat: Phantom and first‐in‐human pilot study (Magn Reson Med. 2022;88:1794‐1805)

The article entitled “Point-of-care magnetic resonance technology to measure liver fat: Phantom and first-in-human pilot study” misstated the recycling delay and the need for T 1 correction in the human study. The recycling delay in the human study was 300 ms, not approximately 1000 ms, and T 1 correction was applied in the estimation of point-of-care NMR proton density fat fraction (POC NMR-PDFF). The effect of this correction is noticeable on Figure 4A, where the relative amplitude of the fat signal is 0.21; after T 1 correction, the fat to total signal ratio is 0.17. Also, the article misstated the shape and volume of the layer interrogated by POC NMR. The interrogated layer is saucer-like in shape, not discoid. Although it spans a depth of 1 cm and is 8 cm in diameter as correctly described in the article, it is about 0.02 cm thick. Hence, its net volume is about 1 cm 3 ( ∼ 0.02 cm × 1 cm × π 4 2 ), not about 10 cm 3 . The authors regret these errors.
