Multi-site feasibility and reproducibility study on UTE 3D phosphorous MRSI using novel rosette trajectory (PETALUTE).

ABSTRACT:

Purpose

This study aims (1) to implement a robust acquisition, fully automated reconstruction, and processing pipeline using a novel rosette k-space pattern for UTE ³¹P 3D MRSI and (2) to evaluate the clinical applicability and reproducibility at different experimental setups.

Methods

A multi-center feasibility/reproducibility study was conducted for the novel UTE ³¹P 3D MRSI sequence with rosette petal trajectory (PETALUTE) at three institutions with different experimental setups (Siemens Prisma with volume head coil or surface coil, Siemens Biograph mMR with volume head coil). Five healthy subjects at each site were measured with an acquisition delay of 65 μs and a final resolution of 10 × 10 × 10 mm³ in 9 min. The measurement was repeated
