Can we image microvasculature below the size of the ultrasound wavelength without the ultrasound contrast? SURE we can! Check out our latest paper on super resolution ultrasound imaging.

A new approach for vascular super-resolution (SR) imaging using the erythrocytes as targets (SUper-Resolution ultrasound imaging of Erythrocytes (SURE) imaging) is described in this paper. SURE imaging does not require contrast agents. The SURE image above showed the renal vasculature of a rat kidney acquired in six seconds. Micro-computed tomography images were also obtained with 5-μm voxel size for validating the SURE images. Comparing the SURE and micro-CT images revealed that vessels with a diameter of 28 μm, five times smaller than the ultrasound wavelength, could be detected, and the dense grid of microvessels in the full kidney was shown for scan times between 1 and 10 s. The vessel structure in the cortex was also similar to the SURE images. Find out more about SURE in the link below.
