Cardiovascular diseasesare the leading cause of death globally , necessitating advanced diagnostic techniques for exact assessment and treatment . Among these , Intravascular Ultrasound ( IVUS ) , Optical Coherence Tomography ( OCT ) , and angiography are striking . This article render a detailed comparison of these mental imagery sensory system , highlight their vantage , limitation , and applications in cardiology .

Intravascular Ultrasound (IVUS)

IVUS is a catheter - based imagery technique that provides a fussy - sectional vista of the inside of the heart ’s artery . It is specially useful for assess the watercraft bulwark and the extent of atherosclerotic brass .

Advantages :

Limitations :

Limited Resolution : liken to OCT , IVUS has a lower resolution , potentially missing fine details .

Optical Coherence Tomography (OCT)

OCT is a light - based tomography proficiency offering high - resolution image of the interior ofblood vessel .

Penetration astuteness : It has a low penetration deepness , take in it less effective for visualizing mystifying vessel anatomical structure .

Angiography

Angiography , in particular coronary angiography , is a wide used technique for fancy the lumen of heart artery .

Contrast Use : The pauperism for contrast factor can pose risks , specially in patient with kidney upshot .

Applications and Complementarity in Clinical Practice

IVUS and OCT :

IVUS / OCT and Angiography :

Conclusion:

Each cardiac imaging sense modality – IVUS , OCT , and angiography – has its unique specialty and limitation . IVUS proffer elaborate images of vas walls and brass burden , while OCT excels in high - resolution imaging of vascular microstructures . Angiography , being less trespassing , provide a general overview of coronary build and descent stream . In clinical practice , these technique often complement each other , providing a comprehensive assessment that guides interposition and improves patient event in cardiology . The choice of technique depends on the specific clinical scenario , patient constituent , and the information ask to conduct discourse determination efficaciously .
