Investigation of the actual implementation of “post‐sedation discharge criteria” and “time‐out” immediately before procedure in endoscopy: A nationwide survey study in Japan

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Post‐sedation discharge criteria for outpatient endoscopy and time‐out procedures immediately before endoscopic examinations are important for ensuring patient safety. This study used a web‐based questionnaire to survey the implementation status and current situation of these practices in Japan in 2024.

Evaluation of Partial Volume Correction Techniques for Sodium MRI of the Achilles Tendon

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2180-2193, April 2026.
ABSTRACT Purpose To evaluate partial volume correction (PVC) techniques for sodium MRI of the Achilles tendon in situ and in vivo. Methods Five PVC methods were evaluated including a volume ratio of the proton and sodium segmentations (PSSR), a modified least trimmed square (3D‐mLTS) linear regression, a geometric transfer matrix (GTM) approach, a ...

Motion Correction in High‐Resolution 3D Brain MRSI Without Water and Lipid Suppression

Magnetic Resonance in Medicine, Volume 95, Issue 3, Page 1323-1335, March 2026.
ABSTRACT Purpose To develop an effective method for correcting head motion in high‐resolution, non‐water‐suppressed MRSI. Methods MRSI scans are susceptible to subject motion due to the long data acquisition time required for sufficient spatial‐spectral encodings.

DREAMER: Rapid and Simultaneous Multiple Contrast Magnetic Resonance Imaging of Solid and Soft Tissue

Magnetic Resonance in Medicine, Volume 95, Issue 3, Page 1513-1527, March 2026.
ABSTRACT Purpose Pediatric craniofacial imaging may involve examination of both the skull and brain tissues via CT and MRI, respectively. DREAMER (Dual Repetition and Echo Acquisition with Multi‐contrast Encoding and Reconstruction) simultaneously acquires solid‐ and soft‐tissue images, potentially providing a rapid, high‐resolution, and radiation‐free

Temperature Mapping During MR‐Guided Cryoablation Using a FLORET UTE Sequence

Magnetic Resonance in Medicine, Volume 95, Issue 3, Page 1653-1659, March 2026.
ABSTRACT Purpose To implement a three‐dimensional FLORET‐UTE sequence for rapid MR thermometry during cryoablation and to validate voxel‐wise temperature maps against fiber‐optic probes in ex vivo bovine liver. Methods A FLORET‐UTE trajectory (TE 50 μs, 1.6 mm isotropic, 18 s/volume) was executed on a 3 T scanner while dry‐ice cryoablation was applied ...

Growth in Production and Environmental Deposition of Trifluoroacetic Acid Due To Long‐Lived CFC Replacements and Anesthetics

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Trifluoroacetic acid (TFA) is a persistent pollutant with potential long‐term effects on the environment and on health. Recent studies using ice core records report large increases (up to tenfold) in Arctic TFA deposition since the 1970s, and trends suggest long‐lived chlorofluorocarbon (CFC) replacements may be a major source.
