9. MRI Subject Post-Scan Procedures9.1 Scan DiscontinuationIf the subject elects to discontinue the MRI because of discomfort every effort should bemade to adjust the table, head coil, etc. and finish acquiring the scan. However, if the subjectstill does not want to complete the scan, then the MRI should be abandoned and noted asincomplete on the INTRuST MRI Scan Worksheet. The comments sections should includethe reason the subject was unable to complete the MRI session.9.2 Archive Procedures9.2.1 Every MRI for INTRuST must be archived at the MRI facility following standard localpractice in addition to the data transfer to the CNDA database as well as the CD/DVD archiveto be delivered to the local study coordinator immediately after the MRI scan.• See Section 10.5 (Appendix 5) for CNDA upload instructions9.2.2 Additional data transfers or copies will be requested by the coordinating center in theevent that a data transfer is interrupted or incomplete. Possible MRI archive mediums include:• Optical Disk• PACS• CD or DVD9.3 Post-Scan Information9.3.1 Following each MRI, the study coordinator at each site needs to fill out the INTRuSTDemographics form on the CNDA for each subject. See Section 10.4 (Appendix 4) forinformation on how to fill out the Demographics form on the CNDA.9.3.2 All subject MRIs need to be read by a clinical radiologist. The radiologist’s report shouldbe entered into the CNDA as instructed in Section 10.5 (Appendix 5).9.4 Requests for Repeat MRI Scans• Reasons for MRI Repeats:o A request for a repeat MRI may be required in the event that the scans are foundto be unacceptable due to subject motion or an incomplete/incorrect MRIacquisition. In this event, your site will be asked to schedule a repeat study.o NLC QC will check all INTRuST scans to be sure that the exam was conductedon the one scanner qualified for INTRuST at your site, and that the correct,electronically loaded sequences have been used to scan each subject. Repeatexams may also be required if the incorrect scan sequence, orientation, orangulations are used. It is imperative to use the INTRuST approved acquisitionsequence with every INTRuST subject. Scans with image degradation due to theincorrect scan sequence, orientation, or angulations will NOT be reimbursed norwill scans acquired on any scanner other than the one qualified for INTRuST. Rescanswill be reimbursed if the correct scan sequence, orientation, andangulations were used.• Procedures for MRI Repeats:o Repeat MRI scans should be performed as soon as possible. The coordinatingcenter for INTRuST will contact the referral site as well as the MRI facilityrequesting a repeat MRI. Detailed information regarding the reason for the repeatas well as suggestions for improvement will be communicated to both sites.
