Contrast-mixing protocol improves GI opacification on CT
Many imaging facilities have developed different protocols for opacification of the gastrointestinal (GI) tract before CT of the abdomen or pelvis. In this article, Dr. Peter Quagliano offers his formula for diluting and administering ionic iodinated contrast for optimal performance in these scans.

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. NIFTI = Neuroimaging Informatics Technology Initiative, 3D = three-dimensional.

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.
