    1. Synergy Between morpHOlogical and inflammatoRy Evaluation in Predicting Long-term Coronary Plaque Progression

      Synergy Between morpHOlogical and inflammatoRy Evaluation in Predicting Long-term Coronary Plaque Progression

      Data from human autopsy studies have showed that thrombosis of a ruptured plaque with a large necrotic core, inflammatory cells and a thin fibrous cap, the so-called thin cap fibroatheroma (TCFA), represents the main mechanism for acute coronary syndrome (ACS). Optical coherence tomography (OCT) is an imaging technique that provides high-resolution, cross-sectional images of tissue in situ. The resolution of OCT (10 um) is appropriate for measuring a cap thickness less than65 μm, and even the plaque macrophage density. 68Ga-DOTA-(Tyr3)-octreotate/NaI3-octreotide(68Ga-DOTA-TATE/NOC) Positron Emission Tomography (PET)/Computed Tomography coronary angiography (CTCA), targeting the somatostatin receptor subtype-2 selectively ...

    2. Comparing Conventional Grid Laser Photocoagulation and Subthreshold Micropulse Laser in Diabetic Macular Edema Using OCT Angiography

      Comparing Conventional Grid Laser Photocoagulation and Subthreshold Micropulse Laser in Diabetic Macular Edema Using OCT Angiography

      The prevalence of diabetes mellitus has increased significantly in Hong Kong for the past decade [1]. Diabetic macular edema is one of the most common causes of vision loss in patients suffering from diabetes mellitus [3]. Before the introduction of anti-vascular endothelial growth factor agents, laser photocoagulation has been the mainstay treatment for patients with diabetic macular edema. There are two types of laser treatment modalities, namely focal laser, which can be applied either in a grid pattern over a region of macular edema or to selected microaneurysms, and subthreshold micropulse laser. Only one meta-analysis published in 2016 [16] had ...

    4. AI Quantitative Coronary Angiography Versus Optical Coherent Tomography Guidance for Coronary Stent Implantation

      AI Quantitative Coronary Angiography Versus Optical Coherent Tomography Guidance for Coronary Stent Implantation

      This original clinical research project utilizes cutting-edge medical imaging technologies for diagnosis of pigmented skin tumours, combined for the first time in Denmark, with molecular RNA and lipid analysis of superficial tumours cells. The scanning technologies are reflectance confocal microscopy (RCM), which is a microscope applied directly to the skin surface, and photoacoustic imaging, also termed multispectral optoacoustic imaging (MSOT), which is an imaging technology actually listening to the skin for immediate bedside diagnosis of pigmented skin tumors. The hypothesis is that treatment guided by diagnostic bedside skin scanning, combined with tumour tape-stripping and RNA and lipid analysis can increase ...

      Coherent Optical Detection of Middle Ear Disease

      Otitis media (OM) is the most common diagnosis in pediatric patients seen for illness in the United States, affects 90% of all children, and is the most common indication for antimicrobial therapy and surgery in young children. Despite many attempts to improve diagnosis, treatment, and prevention, OM continues its highly prevalent impact on children and substantial ongoing morbidity. OM continues as the most common cause of hearing loss in children and leads to speech, educational and other developmental delays. OM causes life-threatening complications and is expensive, resulting in over $5 billion annually in U.S. health care expenditures. Despite the ...

      Ex-vivo Examination of Excisions of Skin Tumors by Confocal Optical Coherence Tomography (LC-OCT) With Integrated Dermoscopy and Comparison With Histology (DERMOCTAV)

      There are mainly 3 types of skin cancer: melanoma, basal cell carcinoma and squamous cell carcinoma. The diagnosis of skin cancers is now based on anatomo-pathological evidence. However, given the progress made, imaging is a technique that now has a full role in the diagnosis of these pathologies. This is particularly the case of confocal optical coherence tomography (LC-OCT), which is a recent imaging technique that has proven itself in ophthalmology with the obtaining of precise images of the retina. LC-OCT can be applied in dermatology according to the following principle: the low intensity laser beam delivered by the LC-OCT ...

      Optical Coherence Tomography Angiography and Choroidal Osteoma

      The choroidal osteoma is a rare benign tumor of choroid, it is bilateral in 10%-25% of cases, affecting usually young women. Previous studies evaluated the morphologic characteristics of tumor-related vasculatures, described as a seafun vascular networks, but none focused on study of vessel density of coriocapillary. The aim of this study is to investigate the potential role of the optical coherence tomography angiography (OCTA) in evaluating the choriocapillary vessel density in order to individuate the changes of this vascular network that may influence the onset of choroidal neovasculariztion. Therefore, OCTA could be useful in the clinical management of the ...

      Evaluating Home Testing Devices for the Management of Glaucoma

      Standard Automatic Perimetry (SAP) is the gold standard test for evaluation of diseases of the visual pathway like glaucoma. Its main goal is to measure differential light sensitivity at several locations in the field of vision. Several devices have been developed since the advent of the Octopus Perimeter and the Humphrey Field Analyzer (HFA) is now the most commonly used machine for checking the visual field. These devices have a number of disadvantages including being stressful for debilitated, ill, or elderly patients to keep their heads still in the perimeter bowl during the test. Recently, several methods have been introduced ...

      RETRIEVE - AMI Study

      Heart attacks are caused by the sudden formation of a clot inside a diseased coronary artery which reduces blood flow beyond the blockage site. During conventional treatment of the blockage with what is known as a stent; a stainless steel tub that keeps the artery open, the clot that has formed is disrupted and is pushed further down leading to damage in smaller blood vessels supplying the heart muscle. This additional damage can lead to long-term heart muscle damage influencing recovery and wellbeing. The original concept that was tested to prevent this 'clot shower' was that of a suction device ...

    17. NA-AION Risk Factors: New Perspectives

      NA-AION Risk Factors: New Perspectives

      Non-arteritic anterior ischemic optic neuropathy (NA-AION) is the most common acute optic neuropathy in the middle-aged and elderly population and can also occur in children and young adults. NA-AION leads to irreversible vision loss, and there is currently no effective treatment. In recent years, acellular calcified deposits in the optic nerve head called optic disc drusen (ODD) have been investigated as an important risk factor for NA-AION in patients under the age of 50. The purpose of the study is to use new diagnostic methods optical coherence tomography (OCT) and OCT-angiography (OCTA) to shed light on risk factors for the ...

      Optical Coherence Tomography Angiography (OCTA) Changes in Patients With Epiretinal Membranes (ERM) With and Without Peeling of the Internal Limiting Membrane (ILM)

      Main objective The objective is to compare two surgical options in vitrectomies for epiretinal membranes using parameters of optical coherence tomography angiography. Background State of the art treatment for epiretinal membranes consists of pars plana vitrectomy, staining of the epiretinal membrane with a blue colouring dye and epiretinal membrane peeling. The vitrectomized space is filled with fluid (balanced salt solution) during the procedure and the fluid can optionally be replaced with air as a final step. After ERM peeling (but before the selection of the tamponade), the internal limiting membrane (the innermost layer of the retina) is either peeled as ...
