This has led to controversies between clinicians demanding CECT not to miss any diagnoses and radiologists reluctant or even refusing CECT in risky patients. A critical review of AKI\/dialysis risk post\u2010CECT in PSA studies was performed based on a Cochrane Library\/Embase\/PubMed search up to December 2024 with stratification for various populations. Among unselected emergency\u2010\/inpatients with chronic kidney disease, CECT was associated with significantly higher AKI incidence than in controls in 8\/10 cohorts (weighted absolute risk increase 4.0 percentage points (pp), cohort range \u22124 to 16.9\u00a0pp at glomerular filtration rate (GFR) &lt;30\u00a0mL\/min\/1.73\u00a0m\n                    <jats:sup>2<\/jats:sup>\n                    ) and dialysis in 5\/6 cohorts (weighted absolute risk increase 1.8\u00a0pp, cohort range 1.0\u20135.9\u00a0pp at GFR &lt;30\u00a0mL\/min\/1.73\u00a0m\n                    <jats:sup>2<\/jats:sup>\n                    ). Corresponding figures regarding cohorts with presumed\/potentially unstable renal function were 1\/10 and 3\/8 cohorts, respectively. No increased risk was found in the five miscellaneous cohorts, but with a few patients with low GFR. Associations between individual contrast medium (CM) doses and AKI\/dialysis were generally lacking. Marked selection bias was evident in one cohort. Thus, the analyses support an association between CECT and AKI in emergency\u2010\/inpatients, including a non\u2010negligible dialysis risk, especially at GFR &lt;30\u00a0mL\/min\/1.73\u00a0m\n                    <jats:sup>2<\/jats:sup>\n                    . PSA studies reporting no increased risk of CECT must be interpreted with caution due to risk for selection bias and the potential masking effects of acute kidney functional recovery. Studies on CM dose or gram\u2010iodine\/GFR ratio correlation with AKI\/dialysis are warranted.\n                  <\/jats:p>","DOI":"10.1111\/joim.70095","type":"journal-article","created":{"date-parts":[[2026,4,20]],"date-time":"2026-04-20T03:25:19Z","timestamp":1776655519000},"page":"5-25","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Contrast\u2010enhanced CT\u2014Nephrotoxic or not?
