      Automatic assessment of calcified plaque and nodule by optical coherence tomography adopting deep learning model
      Optical coherence tomography (OCT) has become the best imaging tool to assess calcified plaque and nodule. However, every OCT pullback has numerous images, and artificial analysis requires too much time and energy. Thus, it is unsuitable for clinical application. This study aimed to develop and validate an automatic assessment of calcified plaque and nodule by OCT using deep-learning model. The OCT images of calcified plaque and nodule were labeled by ...

      Feasibility and Safety of Hybrid IVUS-OCT System
      Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) were all recommended for percutaneous coronary intervention (PCI) optimization in the latest guidelines, however, which imaging modality was more suitable as either a diagnostic or guidance tool was still unknown. Recently, a novel, well-designed hybrid imaging system was approved for clinical use, allowing the accurate co-registration of two imaging modalities and immediate, simultaneous image review. For testing each modality in the hybrid ...

      Image enhancement of wide-field retinal optical coherence tomography angiography by super-resolution angiogram reconstruction generative adversarial network
      Wide-field retinal optical coherence tomography angiography (OCTA) usually suffers from low image resolution in clinical practice because of insufficient lateral sampling. In this study, we develop a deep-learning-based method named super-resolution angiogram reconstruction generative adversarial network (SAR-GAN) to enhance the en face OCTA image quality. A sophisticated home-made spectral-domain OCTA system is employed to capture the data of retinal angiograms with different scanning protocols. High-resolution 3 3 mm 2 OCTA ...

      Clinical Outcomes of Different Calcified Culprit Plaques in Patients with Acute Coronary Syndrome
      Background: Previous studies have found that coronary artery calcification is closely associated with the occurrence of major adverse cardiac events (MACE). This study aimed to investigate the characteristics and clinical outcomes of different calcified plaques in patients with acute coronary syndrome (ACS) by using optical coherence tomography (OCT). Methods: 258 ACS patients with calcified culprit plaques who underwent OCT-guided stent implantation were enrolled. They were divided into three subtypes based ...

      Association Between Dietary Intakes and Plaque Vulnerability Measured by Optical Coherence Tomography in Patients With Coronary Heart Disease: A Mediation Analysis of Inflammatory Factors
      Although studies have proven that diet has a critical role in preventing or delaying atherosclerosis and is far simpler to adjust and adhere to than other risk factors, the underlying mechanisms behind this effect remain not well comprehended. The purpose of this investigation was to determine the impact of inflammatory factors on the connection between dietary ingestion and coronary plaque fragility as measured via optical coherence tomography (OCT) in patients ...

      Cholesterol crystals in non-culprit plaques of STEMI patients: A 3-vessel OCT study
      Background: Cholesterol crystals (CCs) are regular microstructures found within the necrotic core of atherosclerotic plaques and have been hypothesized to be related to plaque destabilization. We attempted to investigate the potential association between CCs and non-culprit plaque vulnerability in patients with ST-segment elevated myocardial infarction (STEMI) and study morphological features of CCs in ruptured non-culprit plaques. Methods: A total of 261 patients with ST-segment elevation myocardial infarction who underwent 3-vessel ...

      In vivo detection of plaque erosion by intravascular optical coherence tomography using artificial intelligence
      Plaque erosion is one of the most common underlying mechanisms for acute coronary syndrome (ACS). Optical coherence tomography (OCT) allows in vivo diagnosis of plaque erosion. However, challenge remains due to high inter- and intra-observer variability. We developed an artificial intelligence method based on deep learning for fully automated detection of plaque erosion in vivo , which achieved a recall of 0.8000.175, a precision of 0.7340.254, and ...
