Intravascular Imaging Technique can Help Detect Unstable Coronary Plaques
Written by AZoOpticsMar 17 2021
A new intravascular imaging approach recently developed by scientists could someday be used for detecting coronary plaques that may trigger a heart attack.
A new technique known as intravascular laser speckle imaging could one day be used to detect coronary plaques that are likely to lead to a heart attack. The researchers developed a small diameter intravascular catheter that incorporates a small-diameter fiber bundle, polarizer, and GRIN lens to image the reflected speckle patterns onto a CMOS sensor.

Generally, heart attacks occur when an unstable plaque bursts open and subsequently inhibits a crucial artery that transports oxygen and blood to the heart.

WASHINGTON Researchers have developed a new intravascular imaging technique that could one day be used to detect coronary plaques that are likely to lead to a heart attack. Heart attacks are often triggered when an unstable plaque ruptures and then blocks a major artery that carries blood and oxygen to the heart. If unstable coronary plaques could be detected before they rupture, pharmacological or other treatments could be initiated early to prevent heart attacks and save lives, said research team leader Seemantini Nadkarni from the Wellman Center for Photomedicine at Massachusetts General Hospital. Our new imaging technique represents a major step toward achieving this.

Raman Spectroscopy may Aid Early Oral Cancer Diagnosis by Colleen Fleiss on January 13, 2021 at 11:37 PM
Raman spectroscopy showed promise for early detection of oral squamous cell carcinoma (OSCC), said researchers.
OSCC is the most prevalent type of oral cancer and ranks among the most common cancers diagnosed worldwide. Although effective treatments are available, the cancer is often not detected until a late stage, resulting in overall poor prognosis. Raman spectroscopy is not only label-free and non-invasive, but it can potentially be used in ambient light conditions, says research team leader Levi Matthies from University Medical Center Hamburg-Eppendorf in Germany. This makes it promising for use as a potential screening tool in the dentist s office.
