Coronary angiography and computed tomography in situs inversus totalis.
CASE PRESENTATION A 65-year-old Hispanic man presented to the emergency department with complaints of intermittent chest pain for 1 year. Coronary angiography demonstrated dextrocardia with situs inversus totalis, confi rmed by subsequent computed tomography (Figure 1). Th e angiogram was performed via the right femoral artery; because the aortic arch was best visualized in the right anterior o...
متن کاملOptical Coherence Tomography Angiography of the Optic Disc; an Overview
Different diseases of the optic disc may be caused by or lead to abnormal vasculature at the optic nerve head. Optical coherence tomography angiography (OCTA) is a novel technology that provides high resolution mapping of the retinal and optic disc vessels. Recent studies have shown the ability of OCTA to visualize vascular abnormalities in different optic neuropathies. In addition, quantified ...
متن کاملOptical coherence tomography angiography of optic disc perfusion in glaucoma.
PURPOSE To compare optic disc perfusion between normal subjects and subjects with glaucoma using optical coherence tomography (OCT) angiography and to detect optic disc perfusion changes in glaucoma. DESIGN Observational, cross-sectional study. PARTICIPANTS Twenty-four normal subjects and 11 patients with glaucoma were included. METHODS One eye of each subject was scanned by a high-speed ...
متن کاملOptical Coherence Tomography Angiography
Optical coherence tomography angiography (OCTA) is a noninvasive approach that can visualize blood vessels down to the capillary level. With the advent of high-speed OCT and efficient algorithms, practical OCTA of ocular circulation is now available to ophthalmologists. Clinical investigations that used OCTA have increased exponentially in the past few years. This review will cover the history ...
متن کاملOptical coherence tomography angiography
Optical coherence tomography (OCT) was one of the biggest advances in ophthalmic imaging. Building on that platform, OCT angiography (OCTA) provides depth resolved images of blood flow in the retina and choroid with levels of detail far exceeding that obtained with older forms of imaging. This new modality is challenging because of the need for new equipment and processing techniques, current l...
