    2. Optical coherence tomography of small intestine allograft biopsies using a handheld surgical probe

      Explore SPIE Digital Library Gastroenterology
      Optical coherence tomography of small intestine allograft biopsies using a handheld surgical probe
      Significance: The current gold standard for monitoring small intestinal transplant (IT) rejection is endoscopic visual assessment and biopsy of suspicious lesions; however, these lesions are only superficially visualized by endoscopy. Invasive biopsies provide a coarse sampling of tissue health without depicting the true presence and extent of any pathology. Optical coherence tomography (OCT) presents a potential alternative approach with significant advantages over traditional white-light endoscopy. Aim: The aim of our ...

      Using Optical Coherence Tomography and Intravascular Ultrasound Imaging to Quantify Coronary Plaque Cap Stress/Strain and Progression: A Follow-Up Study Using 3D Thin-Layer Models
      Accurate plaque cap thickness quantification and cap stress/strain calculations are of fundamental importance for vulnerable plaque research. To overcome uncertainties due to intravascular ultrasound (IVUS) resolution limitation, IVUS and optical coherence tomography (OCT) coronary plaque image data were combined together to obtain accurate and reliable cap thickness data, stress/strain calculations, and reliable plaque progression predictions. IVUS, OCT, and angiography baseline and follow-up data were collected from nine patients ...

      Explore SPIE Digital Library Neurology
      Label-free detection of brain tumors in a 9L gliosarcoma rat model using stimulated Raman scattering-spectroscopic optical coherence tomography
      Significance: In neurosurgery, it is essential to differentiate between tumor and healthy brain regions to maximize tumor resection while minimizing damage to vital healthy brain tissue. However, conventional intraoperative imaging tools used to guide neurosurgery are often unable to distinguish tumor margins, particularly in infiltrative tumor regions and low-grade gliomas. Aim: The aim of this work is to assess the feasibility of a label-free molecular imaging tool called stimulated Raman ...

    5. Three dimensional reconstruction of coronary artery stents from optical coherence tomography: experimental validation and clinical feasibility

      Explore Nature Publishing Group Cardiology
      Three dimensional reconstruction of coronary artery stents from optical coherence tomography: experimental validation and clinical feasibility
      The structural morphology of coronary stents (e.g. stent expansion, lumen scaffolding, strut apposition, tissue protrusion, side branch jailing, strut fracture), and the local hemodynamic environment after stent deployment are key determinants of procedural success and subsequent clinical outcomes. High-resolution intracoronary imaging has the potential to enable the geometrically accurate three-dimensional (3D) reconstruction of coronary stents. The aim of this work was to present a novel algorithm for 3D stent ...

      Optical Coherence Tomography-Based Patient-Specific Residual Multi-Thrombus Coronary Plaque Models with Fluid-Structure Interaction for Better Treatment Decisions: A Biomechanical Modeling Case Study
      Intracoronary thrombus from plaque erosion could cause fatal acute coronary syndrome (ACS). A conservative anti-thrombotic therapy has been proposed to treat ACS patients in lieu of stenting. It is speculated that the residual thrombus after aspiration thrombectomy would influence the prognosis of this treatment. However, biomechanical mechanisms affecting intracoronary thrombus remodeling and clinical outcome remain largely unknown. In vivo optical coherence tomography (OCT) data of a coronary plaque with two ...

      Assessment of retinal microvascular health by optical coherence tomography angiography among persons with HIV
      Microvasculopathy may link HIV-related chronic inflammation and premature multimorbidity. In this proof-of-concept study, we used optical coherence tomography angiography (OCTA) to evaluate the retina as a convenient assessment of microvascular health among persons with HIV (PWH) undergoing surveillance ophthalmic care at Emory from 20182021. Among patients with longstanding HIV, OCTA identified microvascular abnormalities even among eyes without clinical retinal pathology. Retinovascular evaluation by OCTA is a feasible, non-invasive technique for ...

      Homonymous thinning on macular optical coherence tomography indicating retrograde trans-synaptic degeneration from occipital infarctions
      Inner retinal thinning on optical coherence tomography (OCT) occurring through retrograde trans-synaptic degeneration is an increasingly recognized phenomenon, even in acquired retro-chiasmal brain lesions. We describe a man with stable visual field defects from multiple bilateral posterior circulation infarctions, who had ganglion cell complex (GCC) thinning on macular OCT that corresponded precisely with his visual field defects. In contrast to previous reports indicating that peripapillary retinal nerve fiber layer (RNFL ...

      Using optical coherence tomography and intravascular ultrasound imaging to quantify coronary plaque cap thickness and vulnerability: a pilot study
      Background: Detecting coronary vulnerable plaques in vivo and assessing their vulnerability have been great challenges for clinicians and the research community. Intravascular ultrasound (IVUS) is commonly used in clinical practice for diagnosis and treatment decisions. However, due to IVUS limited resolution (about 150-200 m), it is not sufficient to detect vulnerable plaques with a threshold cap thickness of 65 m. Optical Coherence Tomography (OCT) has a resolution of 15-20 m ...

      In vivo Structural Assessments of Ocular Disease in Rodent Models using Optical Coherence Tomography
      Spectral-domain optical coherence tomography (SD-OCT) is useful for visualizing retinal and ocular structures in vivo . In research, SD-OCT is a valuable tool to evaluate and characterize changes in a variety of retinal and ocular disease and injury models. In light induced retinal degeneration models, SD-OCT can be used to track thinning of the photoreceptor layer over time. In glaucoma models, SD-OCT can be used to monitor decreased retinal nerve fiber ...

      Topography and pachymetry maps for mouse corneas using optical coherence tomography
      The majority of the eye's refractive power lies in the cornea, and pathological changes in its shape can affect vision. Small animal models offer an unparalleled degree of control over genetic and environmental factors that can help elucidate mechanisms of diseases affecting corneal shape. However, there is not currently a method to characterize the corneal shape of small animal eyes with topography or pachymetry maps, as is done clinically ...
