This study demonstrates that separate treatment of VFA and MT data in the CRI method causes non-negligible systematic errors in both R1 and cross-relaxation parameters. Our modified CRI data processing approach effectively corrects these errors and does not require any additional measurements, thus maintaining time-efficiency of the original CRI technique.
