Automated calculation of slice-specific volume computed tomography dose index, water-equivalent diameter, and size-specific dose estimation for computed tomography scans.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo develop and validate an automated computational tool for calculating a slice-specific volume computed tomography (CT) dose index (CTDI
methodsA custom ImageJ macro was developed based on methodologies proposed in American Association of Physicists in Medicine reports 220 and 293. The tool employs threshold-based body contour segmentation [-140 Hounsfield unit (HU)] to extract patient cross-sectional areas and calculates slice-specific D
resultsWater phantom validation demonstrated excellent accuracy, with differences of <2.3% for both D
conclusionThe developed ImageJ macro provides accurate, transparent, and low-cost open-source solution slice-specific CT dose estimation that correlates well with commercial systems while offering superior spatial resolution. This automated method overcomes the limitations of traditional dose reporting by providing detailed slice-by-slice dose variations, which are often overlooked in average summary values, allowing for more accurate and clinically meaningful dose assessments. CLINICAL SIGNIFICANCE: This tool supports detailed dose evaluation across scan regions, helping optimize protocols and enhance radiation safety. Its slice-specific approach is especially useful in anatomically complex areas and research, offering clinicians more precise dose information to guide patient care.
