CSF Pulsation Artifacts on ADC Maps Obtained with Readout-segmented EPI

Autor: Mai Kanou, Shinji Naganawa, Mitsuru Ikeda, Toshio Ohashi

Publikováno v: Magnetic Resonance in Medical Sciences

Purpose: Diffusion-weighted imaging (DWI) using readout-segmented EPI (rs-EPI) can minimize distortion and blurring artifacts; however, we sometimes encounter cerebrospinal fluid (CSF) pulsation artifacts on apparent diffusion coefficient (ADC) maps,

Simple Estimation of the Endolymphatic Volume Ratio after Intravenous Administration of a Single-dose of Gadolinium Contrast

Autor: Shinji Naganawa, Michihiko Sone, Mai Kanou, Kayao Kuno, Toshio Ohashi

Publikováno v: Magnetic Resonance in Medical Sciences

Purpose: To evaluate the feasibility of a simple estimation for the endolymphatic volume ratio (endolymph volume/total lymph volume = %ELvolume) from an area ratio obtained from only one slice (%EL1slice) or from three slices (%EL3slices). The %ELvol

Volume Quantification of Endolymph after Intravenous Administration of a Single Dose of Gadolinium Contrast Agent: Comparison of 18- versus 8-minute Imaging Protocols

Autor: Mai Kanou, Toshio Ohashi, Kayao Kuno, Shinji Naganawa, Mitsuru Ikeda, Michihiko Sone

Publikováno v: Magnetic resonance in medical sciences : MRMS : an official journal of Japan Society of Magnetic Resonance in Medicine. 14(4)

PURPOSE We measured the volume of the endolymphatic space by extending a previously proposed less observer-dependent method of area quantification and compared volume measurements obtained using long (18 min, Image A) and short (8 min, Image B) scan
