Effect of delayed acquisition times on Gadolinium-enhanced MRI of the presumably normal canine brain [PDF]
, 2011 A delay in imaging following intravenous contrast medium administration has been recommended to reduce misdiagnoses. However, the normal variation of contrast enhancement in dogs following a delay has not been characterized.

Automated segmentation of choroidal layers from 3-dimensional macular optical coherence tomography scans [PDF]
arXiv, 2021 Background: Changes in choroidal thickness are associated with various ocular diseases and the choroid can be imaged using spectral-domain optical coherence tomography (SDOCT) and enhanced depth imaging OCT (EDIOCT). New Method: Eighty macular SDOCT volumes from 80 patients were obtained using the Zeiss Cirrus machine.

Analysis of retinal and choroidal images measured by laser Doppler holography [PDF]
, 2019 Laser Doppler holography (LDH) is a full-field imaging technique that was recently used in the human eye to reveal blood flow contrasts in the retinal and choroidal vasculature non-invasively, and with high temporal resolution. We here demonstrate that the ability of LDH to perform quantitative flow measurements with high temporal resolution enables ...

Imaging of the Lamina Cribrosa using Swept-Source Optical Coherence Tomography. [PDF]
, 2012 The lamina cribrosa (LC) is the presumed site of axonal injury in glaucoma. Its deformation has been suggested to contribute to optic neuropathy by impeding axoplasmic flow within the optic nerve fibers, leading to apoptosis of retinal ganglion cells. To

THE ETIOLOGY OF CHOROIDITIS. [PDF]
JAMA: The Journal of the American Medical Association, 1905 The following observations regarding the causal relations of choroiditis with rubeola are the results of observations of numerous cases of this disease which have come under my observation. It has always seemed to the writer that the pathology of choroiditis has not been so definitely established or defined as to enable the practitioner to feel that he

An open-source deep learning algorithm for efficient and fully-automatic analysis of the choroid in optical coherence tomography [PDF]
arXiv, 2023 Purpose: To develop an open-source, fully-automatic deep learning algorithm, DeepGPET, for choroid region segmentation in optical coherence tomography (OCT) data. Methods: We used a dataset of 715 OCT B-scans (82 subjects, 115 eyes) from 3 clinical studies related to systemic disease.
