    5. Intravascular Ultrasound and Optical Coherence Tomography in the Procedural Planning and Execution of Left Main Coronary Artery Percutaneous Coronary Intervention

      Intravascular Ultrasound and Optical Coherence Tomography in the Procedural Planning and Execution of Left Main Coronary Artery Percutaneous Coronary Intervention
      Purpose of Review Left main coronary artery disease (LMCAD) is a frequently encountered, high-risk presentation of atherosclerosis, traditionally managed with surgical bypass grafting. Percutaneous coronary intervention (PCI) for LMCAD is an increasingly attractive option for patients with low to intermediate complexity disease or patients at extremely high or prohibitive surgical risk. The goal of this review is to outline the current indications and guideline recommendations regarding PCI for LMCAD and ...

    7. Optical coherence tomography findings in chronic progressive external ophthalmoplegia

      Optical coherence tomography findings in chronic progressive external ophthalmoplegia
      Background: Chronic progressive external ophthalmoplegia (CPEO) is a mitochondrial encephalomyopathy caused by multiple mtDNA abnormalities. There is little information about the changes of ocular fundus with CPEO. The aim of this work was to measure and evaluate changes in the macular retinal thickness and optic nerve head in patients with CPEO using spectral-domain optical coherence tomography and to compare the findings with those of healthy individuals.

    10. Optical Coherence Tomography Angiography Compared with Indocyanine Green Angiography in Central Serous Chorioretinopathy

      Optical Coherence Tomography Angiography Compared with Indocyanine Green Angiography in Central Serous Chorioretinopathy
      The purpose of this article is to compare optical coherence tomography angiography (OCTA) and indocyanine green angiography (ICGA) in patients with central serous chorioretinopathy (CSC). OCTA, ICGA and fluorescein angiography (FA) images of all enrolled patients were collected and compared. Abnormal areas were annotated on en face choriocapillaris OCTA and ICGA images and compared with each other. We found three main types of anomalies in choriocapillaris OCTA images: type A ...

    11. Optical coherence tomography angiography for noninvasive evaluation of angiogenesis in a limb ischemia mouse model

      Optical coherence tomography angiography for noninvasive evaluation of angiogenesis in a limb ischemia mouse model
      We developed an optical coherence tomography angiography technique by improving the speckle contrast algorithm and the imaging process. This technique, which can achieve angiogenesis imaging in vivo without increasing trauma, was used to evaluate the microvasculature in limb ischemia mice. Sixteen left hindlimb ischemia mice were randomly allocated into CuSO 4 and saline groups. Within 7 days after treatment, limb ischemic damage, temperature and histological staining were assessed by traditional ...

      Light-CT in the Diagnosis of Breast Tumor and Lymph Node
      Intraoperative pathological diagnosis such as frozen section and imprint cytology is not routinely recommended in clinical practice because of time and accuracy concerns. Full-field optical coherence tomography (FF-OCT) is a new optical imaging technique that could generate sectioning tomogram from fresh tissue and provide close-to-pathology depiction of the morphological structure and pathological changes in minutes without conventional tissue preparation, slicing, and staining, and dynamic cell imaging (DCI) added the viability ...

    15. Novel Photoacoustic Microscopy and Optical Coherence Tomography Dual-modality Chorioretinal Imaging in Living Rabbit Eyes

      Novel Photoacoustic Microscopy and Optical Coherence Tomography Dual-modality Chorioretinal Imaging in Living Rabbit Eyes
      Photoacoustic ocular imaging is an emerging ophthalmic imaging technology that can noninvasively visualize ocular tissue by converting light energy into sound waves and is currently under intensive investigation. However, most reported work to date is focused on the imaging of the posterior segment of the eyes of small animals, such as rats and mice, which poses challenges for clinical human translation due to small eyeball sizes. This manuscript describes a ...
