Abstract

This study was designed to determine whether ^1^Hโ€MR spectra of locally advanced human rectal adenocarcinoma could be acquired in vivo at 1.5 T. Despite the relatively large size of these neoplasms, only six out of 21 tumors accommodated a voxel size of 8 cm^3^. This was due to air pockets within the tumor mass, which limited voxel positioning. Localized proton spectra were acquired at short (20 ms) and long (135 ms) echo times (TEs) using a singleโ€voxel technique. The most commonly detected metabolites were choline and lipid.

## Abstract Proton MR spectroscopic imaging (^1^Hโ€MRSI) of the human prostate, which has an interesting clinical potential, may be improved by increasing the magnetic field strength from 1.5T to 3T. Both theoretical and practical considerations are necessary to optimize the pulse timing for spectro

## Abstract A new ^1^Hโ€MRS filtering strategy for selective measurement of glycine (Gly) in human brain in vivo at 3.0T is proposed. Investigation of multiple refocusing following a 90ยฐ excitation pulse indicated that triple refocusing is most effective for suppression of the strongly coupled reson

## Abstract Citrate is a secretory product of the normal prostate, a lack of citrate in prostate tissue is expected to be pathognomonic for adenocarcinoma. In the present study proton ABโ€signal characteristics of citrate at low field strength of 1.5 T were investigated by __volume selective spectro
