Sound of nurturing: Advanced photoacoustic and ultrasound imaging of placental hemodynamics.
Article in Placenta, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
The placenta is a transient yet vital organ that regulates maternal-fetal exchange and profoundly influences pregnancy outcomes. Placental hemodynamic dysfunction is central to many major obstetric complications, including preeclampsia and fetal growth restriction. Despite advances in obstetric imaging, existing modalities such as Doppler ultrasound, magnetic resonance imaging, and X-Ray computed tomography remain limited in their ability to resolve placental microvasculature or quantify hemodynamics in vivo. Recent developments in photoacoustic (PA) and advanced ultrasound imaging have enabled assessment of placental vasculature, blood perfusion, and oxygenation with improved spatial and temporal resolution. Photoacoustic microscopy (PAM) and photoacoustic computed tomography (PACT) provide optical contrast derived from endogenous hemoglobin, offering functional insight into oxygen transport and vascular remodeling at various scales, while power Doppler (PWD), and ultrasound localization microscopy (ULM) deliver complementary blood flow and microvascular information at clinically-relevant depths. Integrating photoacoustic and ultrasound imaging allows for quantitative, multiscale visualization of placental hemodynamics from the macroscopic to the microscopic level. This review summarizes current progress in photoacoustic and ultrasound-based placental imaging, discusses different system implementations, reports important preclinical and clinical findings, and identifies remaining challenges in technical improvement and broad translation. Together, emerging photoacoustic and ultrasound imaging platforms promise to transform placental research and reproductive healthcare by enabling comprehensive, functional evaluation of maternal-fetal exchange in health and disease.
