RF-based Quality Intima Media Thickness-RFQIMT method is the next generation IMT real-time measurement for high accuracy and reproducibility in early detection of cardiovascular diseases (e.g. diabetes, hypercholesterolemia, hypertension, etc.) and for detecting early atherosclerosis.
Based on the direct analysis of the radiofrequency signal, this technique is a gold standard for diameter, changes in diameter and wall vessel measurements with high spatial resolution.
The normal arterial wall is composed of two acoustic impe dance interfaces: the transition between blood and intima, and the transition between media and adventitia. The distance between those two acoustic interfaces is the definition for IMT.
Improving techniques (higher frequency probes, better focalization and digital signal processing) together with more advanced stages of disease, additional transitions may appear between the two classical layers. These additional interfaces may correspond to intima hyperplasia, media fibrosis or small plaques. An extended algorithm for interface recognition, applicable on bi-dimensional RF matrix acquisition online and offline, is available with ART.LAB.
The RFQIMT measurement and protocol follow the Mannheim Consensus.
RF-QIMT
Discover the RFQAS, RF-based Quality Arterial Stiffness, the most accurate assessment of arterial vessel health condition. Based on the same RF-based and Real-Time technology, RFQAS provides additional several parameters which combined with the available standard ultrasound acquisition offer to the physician an extraordinary tool to evaluate the arterial stiffness condition.
Starting from the analysis of the blood vessel wall properties, the algorithm is looking at vessel diameter and its relevant distension and stiffness. The procedure is based under the guidance of the Standard Deviation (SD) value, to guarantee an high value in measure feedback reliability.
RF-QAS
The extraordinary importance of RFQAS technology is based on the accurate resolution of the measure (far superior to currently available alternative options). Thanks to the RF analysis, the system can offer increased user independence and greater accuracy of the measurements compared to all other available solutions.
RFQAS (Quality Arterial Stiffness) together with RFQIMT (Quality Intima Media Thickness) are part of the exclusive Esaote Advanced Vascular Package. Due to Real-Time Analysis of the RF signal, the Advanced Vascular Package represents a precise and reliable tool for vascular diagnosis.
