Autor: Liang Yin, ZhangZhu Li, MingYan Shang, ZongChang Li, BoWen Tang, Dan Yu, Jie Gan

Publikováno v: BMC Medical Imaging, Vol 24, Iss 1, Pp 1-8 (2024)

Abstract Background This study aimed to assess the feasibility and performance of 5.0 T MRI in MR Cholangiopancreatography (MRCP) imaging compared to 3.0 T, focusing on detail visualization, signal-to-noise ratio (SNR), and image artifacts. Methods A

Autor: YI Peng, CAO Li, HUANG Zhen, CHENG Xin, WANG Jiaxin, CHEN Li, CHEN Fang, BAO Qingjia, ZHANG Zhi, LIU Chaoyang

Publikováno v: Chinese Journal of Magnetic Resonance, Vol 41, Iss 3, Pp 245-256 (2024)

Based on the independently developed 5 T magnetic resonance imaging (MRI) system and research needs of 13C metabolic MRI, a gradient coil and 1H/13C dual resonance radiofrequency (RF) coil system for small-bore MRI were designed. The gradient coil wa

Linking human cerebral and ocular waste clearance: Insights from tear fluid and ultra-high field MRI

Autor: Merel M. van der Thiel, Nienke van de Sande, Anouk Meeusen, Gerhard S. Drenthen, Alida A. Postma, Rudy M.M.A. Nuijts, Noa van der Knaap, Inez H.G.B. Ramakers, Carroll A.B. Webers, Walter H. Backes, Marlies Gijs, Jacobus F.A. Jansen

Publikováno v: Neurobiology of Disease, Vol 203, Iss , Pp 106730- (2024)

Impaired cerebral waste clearance (i.e., glymphatics) is evident in aging and neurodegenerative disorders, such as Alzheimer's disease, where an impaired waste clearance system could be related to the accumulation of pathological proteins (e.g., tau)

Differential activation of lateral parabrachial nuclei and their limbic projections during head compared with body pain: A 7-Tesla functional magnetic resonance imaging study

Autor: Rebecca V Robertson, Noemi Meylakh, Lewis S Crawford, Fernando A Tinoco Mendoza, Paul M Macey, Vaughan G Macefield, Kevin A Keay, Luke A Henderson

Publikováno v: NeuroImage, Vol 299, Iss , Pp 120832- (2024)

Pain is a complex experience that involves sensory, emotional, and motivational components. It has been suggested that pain arising from the head and orofacial regions evokes stronger emotional responses than pain from the body. Indeed, recent work i
