Visual analysis of emerging topics and trends in contrast agent extravasation research in medical imaging: a bibliometric study using CiteSpace and VOSviewer.

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
Purpose: This study presents a visualization of the global research dynamics on contrast agent extravasation in medical imaging using a knowledge map, revealing the research directions, emerging topics, trends, and frontiers in this field. Method: Using CiteSpace and VOSviewer software with the Web of Science Core Collection database as the data source, a bibliometric analysis was conducted on relevant studies of contrast agent extravasation in medical imaging examinations. Analysis was performed on aspects such as yearly publication volume, country/institution distribution, authorship, co-citation documents, and keywords, leading to the creation of visualizations. Results: A total of 4,635 articles were included in the study, with the first relevant research report appearing in 1950. The yearly publication and citation volumes have shown an overall increasing trend over the years. Research in this field was predominantly concentrated in the United States, accounting for approximately one-third of the global publication output. The University of California System was the top institution in terms of publication volume. The top five high-frequency keywords were "magnetic resonance imaging," "computed tomography," "management," "diagnosis," and "contrast agent." Cluster analysis of keywords revealed three main clusters: "contrast," "fluorescein angiography," and "focused ultrasound," showing good continuity over time. The keyword burst analysis identified that "gd dtpa" had the highest burst value of 20.51. The emergence of keywords shifted over time. At present, the keywords that are still emerging are "multimodal imaging," "case report," and "leakage." Conclusion: More scholars are dedicating efforts to research on contrast agent extravasation in medical imaging. "Multimodal imaging" will be a key research focus in the foreseeable future. Contrast agent extravasation remains a substantial challenge with high research value in medical imaging.
