Local Diagnostic Reference Levels for Common Nuclear Medicine Procedures for Pediatric in Dubai Health.

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
This study aims to establish diagnostic reference levels (DRLs) for common pediatric nuclear medicine (NM) procedures performed within the Dubai Health sector. The established DRLs will serve as a benchmark for pediatric NM practice, supporting standardized healthcare delivery and guiding ongoing quality improvement and internal audit activities. Patient dose survey data were collected from the solo NM center within the Dubai Health sector. The study included common scintigraphy procedures using gamma cameras and the hybrid positron emission tomography with computed tomography (PET/CT) procedures. Scintigraphy procedures include the dynamic and static renal scans, and ocular eye scans. The hybrid PET/CT procedures entail tumor/infection and neuroendocrine scans. Patient demographics, administered activities, CT doses, and study description were recorded. Both weight bands of <5, 5-<15, 15-<30, 30-<50, and 50-<80 kg, and age bands of <1, 1-<5, 5-<10, and 10-<15 years were considered. Statistical analysis was performed to determine the 25th percentile, median and 75th percentile of the dose distribution. The median value was used to establish the DRLs for the Dubai Health sector. The analyses revealed significant variation in the administered activities across the different pediatric NM procedures. The proposed DRLs for various pediatric NM procedures for the weight band 15-<30 kg are as follows: renal dynamic 98.4 MBq, renal static 96.2 MBq, ocular eyes 18.5 MBq, tumor/infection 155 MBq, and neuroendocrine 80 MBq. This work provides the first pediatric NM DRLs for the Dubai Health sector, offering a key reference for developing the local DRLs for the Emirate of Dubai. The findings indicate that achieving meaningful dose optimization will require systematic revision of existing imaging protocols, with targeted parameter adjustments informed by continuous dose monitoring and benchmarking to enhance patient safety and overall diagnostic quality.
