Substance use disorder severity is associated with sensitivity to effort-related decision-making constraints.

Rationale: Several studies have reported associations between substance use and effort-related decision making, or the degree to which effort expenditure impacts the choice between lower and higher value rewards. However, previous research has not explored effort-related decision making in populations with severe substance use disorder.

Objectives: Investigate the association between effort-related decision-making and substance use disorder severity.

Update on MR Imaging of the Acetabular Labrum.

Acetabular labral tears are a mechanical cause of hip pain. Hip MR imaging should be performed on 3T magnets using small field of view and high-resolution imaging. If using a lower strength magnet, direct arthrography should be performed.

The utility of point-of-care dynamic ultrasonography for the diagnosis of subtle isolated ligamentous Lisfranc injuries: a cadaveric study.

Objectives: To assess if Lisfranc injury can be detected by US with and without abduction stress.

Methods: Eight cadaveric feet were obtained. The following measurements were obtained in the uninjured feet: C1M2 and C1C2 intervals and TMT1 and TMT2 dorsal step-off distances.

Diffusion Modeling with Domain-conditioned Prior Guidance for Accelerated MRI and qMRI Reconstruction.

This study introduces a novel image reconstruction technique based on a diffusion model that is conditioned on the native data domain. Our method is applied to multi-coil MRI and quantitative MRI (qMRI) reconstruction, leveraging the domain-conditioned diffusion model within the frequency and parameter domains. The prior MRI physics are used as embeddings in the diffusion model, enforcing data consistency to guide the training and sampling process, characterizing MRI k-space encoding in MRI reconstruction, and leveraging MR signal modeling for qMRI reconstruction.
