Optical Coherence Tomography Guided Percutaneous Coronary Intervention.
Optical coherence tomography (OCT) is an increasingly available intracoronary imaging modality that provides high-resolution imaging of coronary arteries. Its fundamental reliance on the emission and reflection of light enables rapid data acquisition without compromise of image resolution. As such, OCT can inform operators planning percutaneous coronary intervention (PCI) by accurately defining...
متن کاملThe Role of Optical Coherence Tomography in Coronary Intervention
Optical coherence tomography (OCT) is an optical analog of intravascular ultrasound (IVUS) that can be used to examine the coronary arteries and has 10-fold higher resolution than IVUS. Based on polarization properties, OCT can differentiate tissue characteristics (fibrous, calcified, or lipid-rich plaque) and identify thin-cap fibroatheroma. Because of the strong attenuation of light by blood,...
متن کاملValidation of computed tomography-based attenuation correction of deviation between theoretical and actual values for four computed tomography scanners
Objective: In this study, we aimed to validate the accuracy of computed tomography-based attenuation correction (CTAC) using the bilinear scaling method.Methods: The measured attenuation coefficient (μm) was compared to a theoretical attenuation coefficient (μt ) using four different CT scanners and an RMI 467 phantom. The effective energy of the CT beam X-rays was calculated, using the aluminu...
متن کاملApplication of optical coherence tomography in percutaneous coronary intervention.
Optical coherence tomography (OCT) is a high resolution imaging technique that offers microscopic visualization of the coronary artery. The fast scanning speed and simple imaging procedure of new-generation frequency-domain OCT make this technology easy to use in the clinical setting. The OCT examination is useful for guidance and risk stratification of percutaneous coronary intervention (PCI)....
متن کاملUse of multislice computed tomography angiography in percutaneous coronary intervention
The introduction of multislice computed tomography angiography (MSCT) has provided new information for percutaneous coronary intervention (PCI), especially in complex lesions. It provides valuable adjustments about coronary lesions, which are predictors of procedural success, for example, in chronic total occlusions, in bifurcations and recently in aorto-ostial lesion PCI. In multiple fields, t...
