Ultrafast ultrasound localization microscopy for differential diagnosis of reactive hyperplasia and metastatic cervical lymph nodes: a pilot study.

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
Background: Cervical lymph nodes (LNs) play pivotal roles in immune surveillance and oncologic spread. This study investigates the clinical utility of ultrafast ultrasound localization microscopy (ULM) for distinguishing reactive hyperplasia from metastatic cervical LNs, aiming to improve diagnostic precision beyond conventional ultrasound (US) capabilities. Methods: We prospectively analyzed 135 histopathologically confirmed LNs (scheduled for December 2023 to October 2024) using multimodal US assessment: conventional two-dimensional (2D) imaging, superb microvascular imaging (SMI), and ULM. Quantitative parameters [vessel diameter, vascular index (VI), microvascular density (MVD)] and qualitative flow patterns were systematically evaluated against pathological standards. Diagnostic performance was assessed through multivariable logistic regression and receiver operating characteristic (ROC) analysis. Results: Metastatic LNs demonstrated significantly larger mean vessel diameters (155.6±24.9 Conclusions: ULM enhances microvascular characterization of cervical LNs by revealing pathological angiogenesis patterns undetectable through standard ultrasonography. The synergistic combination of ULM with established US modalities achieves optimal diagnostic accuracy, providing a clinically actionable non-invasive approach for metastatic LNs identification. This paradigm may reduce unwarranted invasive procedures while improving pretreatment staging reliability.
