18F-NaF-PET for Identification of TCFA (NaF-PET)
Evaluating the Diagnostic Accuracy of 18F-sodium Fluoride Positron Emission Tomography for Identification of High-risk Vulnerable Coronary Atherosclerotic Plaque in Patients With Coronary Artery Disease
Recently, positron emission tomography(PET) using 18F-Sodium fluoride (NaF) showed promising results for detecting vulnerable plaques in some pilot studies.
In this study, the investigators will evaluate the diagnostic accuracy of 18F-NaF PET for non-invasively detecting vulnerable plaque, diagnosed by optical coherence tomography (OCT).

Descrição detalhada
It has been well known that mechanism of acute coronary syndrome is plaque rupture and occlusion of coronary artery by this plaque rupture. Until now, evaluation of vulnerable plaque have been mainly performed with invasive imaging modalities such as optical coherence tomography or intravascular ultrasound.
Recently, positron emission tomography(PET) using 18F-Sodium fluoride (NaF) showed promising results for detecting vulnerable plaques in some pilot studies.
In this study, we will evaluate the diagnostic accuracy of 18F-NaF PET for non-invasively detecting vulnerable plaque, diagnosed by optical coherence tomography (OCT).

Vulnerable plaque in optical coherence tomogrpahy
OCT-derived vulnerable plaque is defined as composite of thin-cap fibrous atheroma (cap thickness in optical coherence tomography < 60um), prominent macrophage, or prominent microvessels.

Non-vulnerable plaque in Optical coherence tomogrpahy
OCT-derived vulnerable plaque is defined as composite of thin-cap fibrous atheroma (cap thickness in optical coherence tomography < 60um), prominent macrophage, or prominent microvessels.
OCT-derived non-vulnerable plaque is defined as a plaque without any of the findings
