Why imaging should be included in U.S. IT stimulus program
Images and imaging reports must be included in the electronic health record as a criterion for meaningful use, it should occur by 2013, and it should include an explicit recognition of the DICOM standard, according to industry manager Rich Eaton in this AuntMinnie Second Opinion.

Chest CT muscle attenuation predicts future bone density loss
By Will Morton
Muscle and bone loss commonly coexist with aging, but potential links between paraspinal muscle and thoracic vertebral bone mineral density loss remain poorly understood
September 15, 2026
Study overview. (A) Volumetric segmentation of the paraspinal musculature was performed for 1,316 participants. (B) Manual segmentation was performed, the results were compared with the volumetric segmentation results, and the Dice score and the intersection over union were calculated. (C) The three-dimensional segmentations from T1 through T10 were individually extracted and combined into a single volume for analyses. (D) Muscle volume and median muscle attenuation were derived from the segmentation volumes. (E) Analyses were performed to assess the correlation of the paraspinal muscle attenuation and volume with the bone mineral density and the ability to predict vertebral fractures.

National and state neighborhood-level disadvantage rankings of the study patients. (A) National disadvantage rankings are shown. Left: area deprivation scores mapped onto the state of Wisconsin, where the study sample resides, with national ranking deciles shown. Blue indicates less disadvantaged neighborhoods, whereas red indicates more disadvantaged neighborhoods. Right: histogram quantifying the number of patients in each Area Deprivation Index (ADI) decile. (B) Same as A, but state ranking deciles are shown. The distributions of both the national and state-level ADI rankings of the patients were skewed toward less disadvantaged neighborhoods. Maps were obtained from reference 36.

CAIX-targeted PET tracer shows promise in patients with ccRCC
By Will Morton
Ga-68 DPI-4452 PET/CT correctly identified all 23 primary clear cell renal cell carcinoma tumors, achieving 100% sensitivity.
September 14, 2026
Representative Ga-68 DPI-4452 PET/CT images of regional and distant metastases in ccRCC from multiple patients, including regional lymph node (A), bilateral adrenal glands (B), lung (C), and bone (D). For each panel, top row shows fused PET/CT images, middle row shows PET-only images, and bottom row shows unenhanced CT images. Target lesions are highlighted by white arrows on fused/CT images and black arrows on PET images.
