BACKGROUND Local structural and metabolic as well as inter-regional connectivity abnormalities have been implicated in the neuropathology of major depressive disorder (MDD). How local tissue properties affect intrinsic functional connectivity is, however, unclear. Using a cross-sectional, multi-modal imaging approach, we investigated the relationship(More)
BACKGROUND AND PURPOSE Because it is a small subcortical structure, the precise measurement of the human LGN is still a technical challenge. In this article, we identify the LGN in vivo, measure its volume based on high-resolution MR imaging, and then relate its volume to subject age to evaluate the potential clinical application.

BACKGROUND AND PURPOSE Prelingual deafness is a hearing loss that occurs before language is acquired and may result in brain structural alterations. We studied microstructural WM alterations in prelingually deaf adolescents by using DTI. We hypothesized that any morphologic alterations are mainly located in the auditory association areas. Furthermore,(More)
BACKGROUND Indirect traumatic optic neuropathy (ITON) is a devastating cause of permanent visual loss. Axonal degeneration, the characteristic pathological change of ITON, cannot be assessed by conventional imaging. Diffusion tensor imaging (DTI) has been widely used as a sensitive non-invasive imaging technique to obtain information on axonal integrity. (More)

OBJECTIVE Optic neuritis (ON) is defined as an inflammation of the optic nerve and provides a useful model for studying the effects of inflammatory demyelination of white matter. The aim of this study was to assess the diffusion changes in both the optic nerve and optic radiation in patients with acute and chronic ON using diffusion tensor (DT) MRI. (More)
INTRODUCTION The peripheral perfusion index (PI) is a noninvasive numerical value of peripheral perfusion, and the transcutaneous oxygen challenge test (OCT) is defined as the degree of transcutaneous partial pressure of oxygen (PtcO2) response to 1.0 FiO2. The value of noninvasive monitoring peripheral perfusion to predict outcome remains to be established(More)
BACKGROUND Electrical impedance tomography (EIT) is a real-time bedside monitoring tool, which can reflect dynamic regional lung ventilation. The aim of the present study was to monitor regional gas distribution in patients with acute respiratory distress syndrome (ARDS) during positive-end-expiratory pressure (PEEP) titration using EIT. METHODS Eighteen(More)
We read with great interest the study by Hernandez and colleagues published in Critical Care [1]. The study showed that central venous oxygen saturation (ScvO 2) increased significantly in response to emergency intubation, and the authors suggested that the early normalization of ScvO 2 after intubation might not be reliable to reflect successful(More)
Anticoagulation is widely used for preventing membrane oxygenator thrombosis during extracorporeal membrane oxygenation (ECMO) therapy while anti-platelets are rarely used, especially in patients with thrombocytopenia [1]. Here we report a case of successfully using anti-platelet treatment to prevent recurrent extracorporeal membrane oxygenator thrombosis(More)
