AI‑detected mrEMVI links to lower 3‑year disease‑free survival in rectal cancer.

Journal article

In a multi‑center retrospective study of 2,501 rectal cancer patients, an nnUNet‑based AI model segmented MRI‑detected extramural vascular invasion and patients classified as AI‑mrEMVI+ had a 3‑year disease‑free survival of 62.3% versus 84.9% for AI‑mrEMVI‑ patients. [1]

Tomosynthesis and synthesized‑image AI scores not interchangeable in biopsy‑referred breast cohort.

Journal article

In 139 breast observations from biopsy‑referred women, researchers tested whether tomosynthesis‑ and synthesized‑image‑based AI malignancy scores are interchangeable. The tomosynthesis score flagged more malignant lesions (21 vs 6) than the synthesized score. Adding either score improved fit, but AUC gains were small and decision‑curve benefits uncertain. Authors advise not using a low AI score alone to downgrade a suspicious finding. [2]

Shifting intelligence upstream improves authorization, a top‑three denial driver.

Podcast from Lifers (Second Opinion)

The interview describes moving clinical data intelligence and documentation improvement upstream—before the payer’s first‑pass denial—to improve authorization, which it cites as a top‑three driver of denials, and notes that payer‑side authorization costs are two to three times provider‑side costs.

Policy & Governance

CHAI releases AI intake playbook with 40% attestation controls.

The Coalition for Health AI released an AI Intake Playbook and Controls and Evidence Workbook containing 57 draft controls across 11 domains, synthesized from over 800 existing questionnaire items. Forty percent of the controls can be satisfied by vendor attestation alone. Currently, reviewers spend more time gathering missing information and following up than conducting the assessment itself.

Clinical Practice

Med‑school hiatus may make memorization irrelevant to future AI‑era duties.

Podcast from AI and Healthcare

The interview describes Ezekiel Emanuel’s worry that entering medical school now means disappearing for two years to learn material whose memorization will likely fall outside future responsibilities, causing trainees to miss the gradual skill accrual akin to picking up a new sport slowly over time.
