Human lymph node microvascular imaging using a fast contrast-free super-resolution ultrasound technique.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Lymph nodes play a crucial role in cancer metastasis, and assessing lymph node involvement is essential for patient prognosis and treatment strategies. Super-resolution ultrasound imaging (SRUS), including ultrasound localization microscopy (ULM), has shown promise in visualizing the lymph node microvasculature, however, ULM requires microbubbles injection, monitoring, and long acquisition times. This study investigates the feasibility of using a fast contrast-free SRUS approach based on erythrocytes (SURE) to visualize and quantify the microvasculature in human lymph nodes. The SURE pipeline detects and tracks erythrocyte scatterer peaks to generate high-resolution microvascular images with a resolution of less than half the wavelength in 2 seconds of data acquisition. SURE visualized the microvasculature, flow direction, and velocity in four normal human lymph nodes, detecting vessels as small as 40 μm in diameter and blood flow velocities ranging from 2 to 15 mm/s. The time evolution of SURE images from 0.1 to 10 seconds was demonstrated, and the SURE consistency was validated by processing SURE images of the same lymph node acquired at different time points. The SURE approach offers a fast contrast-free method for assessing human lymph node microvascular characteristics, providing a promising tool for lymph node evaluation in clinical settings.
