Purpose To evaluate Chemical Exchange Saturation Transfer (CEST) MRI for liver imaging at 3.0-T. Materials and methods Images were acquired at offsets (n = 41, increment = 0.25 ppm) from −5 to 5 ppm using a TSE sequence with a continuous rectangular saturation pulse. Amide proton transfer-weighted (APTw) and GlycoCEST signals were quantified as the asymmetric magnetization transfer ratio (MTRasym...
The aim of this study was to explore the feasibility and repeatability of amide proton transfer‐weighted (APTw) MRI for the head and neck on clinical MRI scanners. Six healthy volunteers and four patients with head and neck tumors underwent APTw MRI scanning at 3 T. The APTw signal was quantified by the asymmetric magnetization transfer ratio (MTRasym) at 3.5 ppm. Z spectra of normal tissues in the...
