Insight into sonography specialists' knowledge concerning grayscale and doppler artifacts: across-sectional survey study in Sudan.
Article in BMC research notes, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundB-mode grayscale and Doppler ultrasound imaging often encounter artifacts, which are misrepresentations of actual anatomy or image degradation due to incorrect assumptions about ultrasound propagation and interaction with tissues. The presence of certain artifacts may compromise image quality and necessitate elimination, while others contribute to and enhance diagnosis.
objectiveTo evaluate the Sudanese Sonographic Specialists’ Knowledge About Grayscale and Doppler Ultrasound Artifact. METHODOLOGY: This was cross-sectional survey study conducted through an online questionnaire distributed through social media from March to July 2025. The sample size included 152 participants, most of whom were females (69.1%) and held a master’s degree (73.0%). In their first five years of experience (67.8%). The data were analyzed using SPSS version 27 (IBM, Armonk, NY, USA) and the DATAtab statistical online calculator 2025. Descriptive and inferential statistics were applied.
resultsSonographers demonstrated good knowledge about grayscale and Doppler artifacts, with a percentage of knowledge (74.5%), with grayscale knowledge being more than Doppler artifacts. No significant differences were found between knowledge scores and demographic factors such as age, education level, and years of experience (P value > 0.05).
conclusionThe study concluded that sonographers have good knowledge of ultrasound artifacts but highlighted the need for more training, especially on Doppler artifacts. Targeted educational programs on ultrasound artifacts are crucial to enhance diagnostic skills and improve patient care.
