High-definition intravascular ultrasound: current clinical uses

Identification of Coronary Healed Plaque Using a Combined High-Definition 35–65 MHz Intravascular Ultrasound and Near-Infrared Spectroscopy

“… 4) High-definition IVUS demonstrated a superior capability in assessing plaque microstructure. 5) Our finding suggests that plaques with layered morphology and low lipids via IVUS-NIRS may indicate HPs, considering that plaque layering involves collagen-mediated healing rather than intra-intimal lipid accumulation. 1)2)…”

Silicon photonic acoustic detector (SPADE) using a silicon nitride microring resonator

“…For intravascular imaging applications, which require high levels of miniaturization, high sensitivity, and wide bandwidths, MRR-SPADE is also a viable alternative to existing piezoelectric technology. In the case of intravascular imaging [41] , acoustic focusing capabilities would need to be added to MRR-SPADE, which may be achieved by bonding the sensor to an acoustic lens, as demonstrated in Refs. [42] , [43] , or by utilizing larger microrings, which exhibit a needle-shaped focus [44] , [45] , [46] .…”

Advancements in Percutaneous Coronary Intervention Techniques: A Comprehensive Literature Review of Mixed Studies and Practice Guidelines

“…IVUS generates grayscale, cross-sectional pictures of the artery wall and is currently refined with improved tissue identification technology [ 46 ]. It is most commonly used in cardiac interventional procedures to describe the lesion shape, measure atherosclerosis load, guide stent size, evaluate stent expansion, provide information on stent deployment accuracy, and identify procedural complications [ 47 ].…”
