Abstract

Purpose QuantitativeT1mapping is a magnetic resonance imaging technique that estimates the spin‐lattice relaxation time of tissues. Even thoughT1mapping has a broad range of potential applications, it is not routinely used in clinical practice as accurate and precise high resolutionT1mapping requires infeasibly long acquisition times. Method To improve the trade‐off between the acquisition time, signal‐to‐noise ratio and spatial resolution, we acquire a set of low resolutionT1‐weighted images and directly estimate a high resolutionT1map by means of super‐resolution reconstruction. Results Simulation and in vivo experiments show an increased spatial resolution of theT1map, while preserving a high signal‐to‐noise ratio and short scan time. Moreover, the proposed method outperforms conventional estimation in terms of root‐mean‐square error. Conclusion Super resolutionT1estimation enables resolution enhancement inT1mapping with the use of standard (inversion recovery)T1acquisition sequences.

  • Super-resolution for MRI can be used to improve the trade-off between resolution, SNR, and acquisition time, generate 7T-like MR images on 3T MRI scanners, or obtain super-resolution T1 maps from a set of low resolution T1 weighted images.

    “Super-resolution for MRI have been around for almost 10 years [192, 193] and can be used to improve the trade-off between resolution, SNR, and acquisition time [194], generate 7T-like MR images on 3T MRI scanners [195], or obtain super-resolution T 1 maps from a set of low resolution T 1 weighted images [196].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
