New Delhi, Jan 23 (NationPress) A group of researchers from Germany has introduced an innovative imaging technology capable of noninvasively examining skin while simultaneously uncovering early indicators of cardiovascular risk.

The Fast-RSOM skin scanning technique identifies minuscule alterations in blood vessels, oxygen saturation, and tissue structure that conventional imaging fails to detect.

This technology can produce high-resolution images of the tiniest blood vessels through the skin, allowing for the assessment of subtle changes in their ability to dilate and constrict, a condition referred to as microvascular endothelial dysfunction (MiVED).

Previously, medical professionals lacked an accurate and noninvasive method to visualize or quantify these preliminary changes in patients.

The team from the Helmholtz Association of German Research Centres believes that by identifying early signs of heart disease risk, this technology could enable doctors to take action sooner, tailor personalized treatments, and enhance overall heart health.

“With Fast-RSOM, we can, for the first time, noninvasively evaluate endothelial dysfunction at the level of single capillaries and skin layers in humans,” stated Dr. Hailong He, a researcher at the Institute of Biological and Medical Imaging at Helmholtz Munich.

“Our groundbreaking technique provides an unparalleled perspective on how cardiovascular disease develops at the microvascular level,” added Dr. Angelos Karlas, co-first author, vascular surgeon, and senior research scientist at Technical University of Munich (TUM) University Hospital.

This research is published in the journal Light: Science & Applications.

Fast-RSOM supplies high-resolution, dynamic MiVED biomarkers, illustrating subtle deficiencies in blood vessel functionality that typically occur before clinical symptoms or observable macroscopic disease characteristics manifest.

These initial changes are frequently associated with risk factors such as smoking, high blood pressure, or obesity. Unlike traditional risk assessments based on descriptive conditions, Fast-RSOM quantitatively captures the actual alterations imposed by these conditions on the microvascular system, long before severe complications arise.

By detecting these early warning signs, Fast-RSOM paves the way for improved early detection, prevention, and more accurate monitoring of cardiovascular health. This technology could assist in pinpointing individuals at greater risk of experiencing cardiovascular events and tracking lifestyle or therapeutic interventions, according to the research team.

The RSOM (Raster Scan Optoacoustic Mesoscopy) is a noninvasive imaging technology that employs light pulses to generate ultrasound signals, yielding exceptionally detailed 3D images of structures beneath the skin.
