- Coronary Plaque Burden, Distribution, and Perivascular Fat Characteristics in Patients with Diabetes Mellitus: A Coronary CT Angiography Study. [Journal Article]Acad Radiol. 2026 Sep 29. [Online ahead of print]AR
- CONCLUSIONS: FAI analysis reveals distinct inflammatory patterns and heterogeneity among diabetic phenotypes. Higher perivascular FAI in the coronary segment located 2 mm distal to the plaque was showed in DM patients, while the biological significance of this spatial pattern remains uncertain. Diabetes increased overall coronary plaque burden without altering vessel-specific distribution patterns. Napkin-ring sign was associated with higher FAI and showed a significant interaction with diabetes status.

- Contrast-Enhanced Ultrasound Evaluates Pathological Response Grades After Neoadjuvant Therapy in Colorectal Liver Metastases. [Journal Article]Acad Radiol. 2026 Sep 24. [Online ahead of print]AR
- CONCLUSIONS: CEUS five-grade patterns provided a non-invasive method for evaluating pathological response to neoadjuvant therapy in CRLM. These findings support further investigation of CEUS as a complementary modality to CEMRI, particularly for patients lacking baseline imaging or with contraindications to CEMRI.

- Spinal Cord Injury Severity Influences Microstructural Alterations in the Supraspinal Somatosensory Pathways. [Journal Article]Acad Radiol. 2026 Sep 24. [Online ahead of print]AR
- CONCLUSIONS: This study demonstrated that SCI induces severity-dependent remodeling within supraspinal somatosensory pathways, providing a foundation for targeted and stratified clinical therapeutic strategies. ISCI is characterized by the coexistence of widespread axonal injury and repair, while CSCI features localized demyelination correlated with sensory dysfunction.

- Comparing Quantitative T1 Mapping and Qualitative Functional Liver Imaging Score (FLIS) for Liver Functional Reserve Stratification: A Comparative Diagnostic Analysis. [Journal Article]Acad Radiol. 2026 Sep 24. [Online ahead of print]AR
- CONCLUSIONS: The FLIS components showed graded associations with the corresponding quantitative imaging measurements, while the T1 reduction rate demonstrated higher diagnostic performance than the total FLIS score for identifying ALBI-defined liver dysfunction in our cohort. These findings warrant prospective external evaluation of the potential complementary roles of FLIS and T1 mapping.

- Physician, Make Thyself: Art-making, Authenticity, and Finding Meaning in the Burnout Crisis. [Journal Article]Acad Radiol. 2026 Sep 23. [Online ahead of print]AR
- Physician burnout persists despite sustained institutional efforts to promote clinician well-being. This perspective explores art-making as a means of reclaiming agency, identity, and meaning within medical practice. Through the act of making-bringing something into existence and recognizing oneself in it-physicians may counteract key domains of burnout, including depersonalization and diminished…
