Limitations of angiography, the normal invasive process for assessing vascular pathology, have ended in an curiosity in replacement invasive thoughts that visualize the arterial wall and make allowance characterization of plaque sort. those substitute strategies, which come with intravascular ultrasound, angioscopy, thermography, optical coherence tomography, close to infrared spectroscopy, and intravascular magnetic resonance imaging may be able to supply necessary information about plaque vulnerability, the composition of plaque, and luminal morphology.

Intravascular Imaging: present purposes and examine Developments offers all on hand intravascular imaging strategies and analyzes their effect in medical perform and learn. This booklet goals to notify scientific experts, biomedical engineers, bioinfomaticians, and researchers of present advancements and destiny traits in intravascular imaging recommendations, selling persisted evolution of this discipline.

The stent is well expanded and apposed to the vessel wall; d) Stent struts (visible from 3 to 9 o’ clock). Intimal hyperplasia inside the stent struts is evident all around the vessel. 20 Intravascular Image Interpretation IVUS is considered to be the gold standard for the differentiation of a true aneurysm from a pseudoaneurysm. A true aneurysm is defined as a lesion that includes all vessel wall layers with a luminal and EEM diameter that are >50% larger than the proximal reference segment, while a pseudoaneurysm appears as a disruption of the EEM and usually observed after PCIs.

Echolucent (soft) plaques described above are believed to represent potentially unstable coronary lesions. These plaques are seen more frequently in high risk patients and are associated with positive (expansive) remodeling and have an increased lipid-rich component. , 2009). Unfortunately, the fibrous cap, seen as an echogenic border at Intravascular Image Interpretation the lumen-intima interface, is expected to be so thin in unstable plaques (< 65 μm) that cannot be detected with IVUS. , 2010).

Frequency domain analysis may allow detailed assessment of plaque composition. Currently, algorithms that permit the identification of tissue composition by in vivo analysis of the radiofrequency signals have been incorporated into the IVUS console and ‘Virtual histology’ has been adapted into clinical and research setting. Despite all these new technological advancements and the appearance of several publications in relation to these new modalities, the clinical value of these advanced image analysis is not completely defined.
