Renal pseudotumors, which mimic tumors on imaging, pose diagnostic challenges that can lead to unnecessary interventions. Sensing ultrasound localization microscopy (sULM) is an advanced imaging technique that uses ultrasound imaging and microbubbles as sensors to visualize kidney functional units. This study aims to investigate whether sULM could differentiate between renal pseudotumors and tumors based on the presence of glomeruli.

Super-resolution ultrasound (SRUS) has evolved significantly with the advent of Ultrasound Localization Microscopy (ULM). This technique enables sub-wavelength resolution imaging using microbubble contrast agents. Initially confined to 2D imaging, ULM has progressed towards volumetric approaches, allowing for comprehensive three-dimensional visualization of microvascular networks.

Cerebral circulation ensures the proper functioning of the entire human body, and its interruption, i.e. stroke, leads to irreversible damage.

- Glomeruli are key kidney filtration units dependent on microcirculation, but traditional imaging struggles to accurately measure their blood flow.
- The introduction of sensing Ultrasound Localization Microscopy (sULM) allows for better visualization of kidney structures in 2D, though it has limitations in capturing comprehensive depth information.
- By extending sULM to 3D imaging, this study enhances the ability to analyze glomerular function and assess kidney health, potentially improving diagnostic methods and patient care in clinical settings.
