The cortical perfusion index (PI) measured by contrast‐enhanced ultrasonography was used as a proxy of renal microcirculation. We measured the PI at rest and during a 2‐minute CPT in patients with ...

This study examines previously unexplored sex differences of the renal microcirculation of participants with hypertension using contrast‐enhanced ultrasonography ... fasting participants arrived at ...

The enhanced contrast means that in some cases ultrasound could be used instead of MRI and CT scans, which are more expensive and harmful to the body. The study was published in Biomaterials Advances.

B-mode provides high-resolution visualization of the lesion and of its boundaries and relationships. Pioneering modes, such as contrast-enhanced ultrasound (CEUS), ultrasensitive Doppler, and ...

Jan. 15, 2025 — Researchers have designed process that uses ultrasound to modify the behavior of cancer-fighting T cells by increasing their cell permeability. They targeted freshly isolated ...

An MRI is meant to be used along with a mammogram, not instead of. “MRI is the most sensitive test we have for finding breast ...

Microbubbles have two basic components—the outer shell, (designed to have varying resistance to ultrasound destruction ... suboptimal (and subsequently contrast-enhanced) studies vs.

GE HealthCare has announced a $138m investment to expand its contrast media manufacturing ... and Drug Administration for its enhanced Voluson Expert Series ultrasound systems, which include ...

The second stage then uses an enhanced quantum evolution network ... However, the precise segmentation of organs in ultrasound images remains challenging, as 1) the boundaries of organs (i.e., ...

This repository contains the code for the paper "No-Reference Quality Assessment of Contrast-Distorted Images using Contrast Enhancement", and presents the results on CCID2014，CID2013，CSIQ and TID2013 ...
