Summary of what happened:
Hello everyone, our MR imaging center recently underwent the upgrade from Siemens VE11 to XA30. Many of the labs that use the scanner (Prisma 3.0T) use CMRR sequences. During the upgrade, we lost an option that allowed us to reduce TR and TEs to the measurements we were previously using.
Namely, the unavailability of GRE as an option for Resolution → Acceleration → Reference scan mode seems to be where most of our issue is coming from. Our current options are Single-shot, Segmented, and FLEET.
We have installed the necessary SD05 patch per this GitHub discussion thread. I can also confirm that we have the latest R017 release (pre11) for XA30 installed. Certificates and sequences included (U of M:CMRR:Downloads:Multi-Band Accelerated EPI Pulse Sequences).
Has anyone else had this issue and fixed it? I apologize for the lack of details. The proprietary nature of this closed software makes it hard to troubleshoot on ones’ own, especially with a system as sensitive (and expensive) as this.
