Guidelines for imaging in Neuro-ophthalmic and Orbital disease

Kerala Journal of Ophthalmology, 2016
Neuroimaging has progressed from plain X-ray to magnetic resonance imaging, noninvasive angiography, and special sequences. Utilization of the appropriate investigation can save the sight and sometimes life of the patient.

Natural History and Management of Familial Paraganglioma Syndrome Type 1: Long-Term Data from a Large Family [PDF]

, 2020
Head and neck paragangliomas are the most common clinical features of familial paraganglioma syndrome type 1 caused by succinate dehydrogenase complex subunit D (SDHD) mutation. The clinical management of this syndrome is still unclear.

Gadolinium-Enhanced Extracranial MRA Prior to Mechanical Thrombectomy Is Not Associated With an Improved Procedure Speed

Frontiers in Neurology, 2019
Objectives: To assess whether performing a pre-intervention gadolinium-enhanced extracranial magnetic resonance angiogram (MRA) in addition to intracranial vascular imaging is associated with improved thrombectomy time metrics.Methods: Consecutive ...

Segmentation method for cerebral blood vessels from MRA using hysteresis [PDF]

arXiv, 2023
Segmentation of cerebral blood vessels from Magnetic Resonance Imaging (MRI) is an open problem that could be solved with deep learning (DL). However, annotated data for training is often scarce. Due to the absence of open-source tools, we aim to develop a classical segmentation method that generates vessel ground truth from Magnetic Resonance ...

Tidsskrift for den Norske laegeforening : tidsskrift for praktisk medicin, ny raekke, 2000
MR angiography (MRA) is a group of MRI techniques capable of producing projectional images of arteries and veins without the use of ionising radiation or catheters.This review describes two of the main techniques, time-of-flight (TOF) MRA and phase contrast MRA, that provide high signal-intensity vessels due to flow phenomena, and a third main ...

A neural network model that learns differences in diagnosis strategies among radiologists has an improved area under the curve for aneurysm status classification in magnetic resonance angiography image series [PDF]

arXiv, 2020
Purpose: To construct a neural network model that can learn the different diagnosing strategies of radiologists to better classify aneurysm status in magnetic resonance angiography images. Materials and methods: This retrospective study included 3423 time-of-flight brain magnetic resonance angiography image series (subjects: male 1843 [mean age, 50.2 +/

Diagnostic accuracy of 3.0-T magnetic resonance T1 and T2 mapping and T2-weighted dark-blood imaging for the infarct-related coronary artery in Non-ST-segment elevation myocardial infarction [PDF]

, 2017
Background: Patients with recent non–ST‐segment elevation myocardial infarction commonly have heterogeneous characteristics that may be challenging to assess clinically. Methods and Results: We prospectively studied the diagnostic accuracy of 2 novel (
