Scientists have developed an innovative imaging approach that may fundamentally change the way we monitor patients with stents. The research recently published in Optics Letters demonstrates photoacoustic microscopy’s capacity to peer through skin and visualize stents. That’s why this groundbreaking technology provides a safer, less invasive and more effective method of tracking these medical devices.
The study was led by co-lead researchers Sung-Liang Chen from Shanghai Jiao Tong University and Myeongsu Seong from Xi’an Jiaotong-Liverpool University. In this research endeavor, they were accompanied by fellow co-researcher Siqi Liang. Each year, about two million Americans get stents to open up blood flow in narrowed or blocked arteries. This further underscores the urgent need for improved monitoring approaches.
Understanding Photoacoustic Microscopy
Photoacoustic microscopy harnesses the unique properties of light and sound to create exquisite, multi-dimensional images of internal structures. This cutting-edge approach has extraordinary potential to enable noninvasive medical imaging. In their study, Chen and Seong used this technique to high-density image stents. They showed its superiority in differentiating between plaque and stent materials.
To recreate a plaque or blood clot deposition like what would occur after stenting, the researchers used butter to help replicate those conditions. This inventive tactic let them put the full maneuverability of photoacoustic microscopy through its paces in more natural, life-like conditions. By using those two very specific wavelengths—670 nm and 1210 nm—the team was able to differentiate plaque buildup from the stent itself.
Key Findings of the Research
To assess under what conditions photoacoustic microscopy performed well, the researchers undertook a rigorous experimental campaign. They placed particular emphasis on imaging stents through excised mouse skin, highlighting the technique’s potential for practical use in human patients. Their results show that this technique has the potential to clearly visualize stents without an invasive procedure.
The capacity to monitor stents noninvasively has the potential to greatly improve patient care in a variety of ways. Currently, these techniques use costly and invasive imaging modalities, which not only risk harming the patient, but force the patient to undergo further recovery. Photoacoustic microscopy provides a non-invasive option, enabling healthcare providers to monitor stent performance and identify complications before they develop.
Implications for Future Medical Practices
The impact of this research goes far beyond imaging stents alone. Photoacoustic microscopy has demonstrated tremendous promise toward realizing this success. This in turn would promote its adoption in surveillance of other types of medical implants and other diseases. As the technology matures, it will soon be standard practice to include it in every exam. This is especially important for patients with stents or other similar devices.
As healthcare specialists continue to find ways to improve patient outcomes, noninvasive methods such as photoacoustic microscopy emerge as effective alternatives. Chen, Seong, and Liang’s study highlights that possibility by paving the way for new diagnostic tools. These tools are designed with patient safety in mind and provide important information about the effectiveness of different medical interventions.
