Case Study Summary: MRI Optimize Consultants improved Lumbar MRI image quality. While creating a time reduction in MRI lumbar spine exams by 14% at this site, this ultimately condensed the annual total lumbar mri study time by almost one week of operational MRI time per year!
Below are the results of the improved lumbar MRI case study. The full results of this improved lumbar MRI study resulted in time savings, staff savings, energy savings in operational time and revenue gain.
Here is what we did:
The typical study included the following sequences:
1) the localizer scout
2) Sagittal T2 weighted series
3) Sagittal T1 weighted series
4) Sagittal STIR series
5) Axial T2 upper slab
6) Axial T2 lower slab
We optimized time after time, the image quality of each mri sequence, by testing the physics parameters time after time on volunteers and patients.
Building upon our previously tested and built sequences, we continually optimized the sequences to maximize the image quality.
The time saved on each exam calculated to be 14% (fourteen percent).
When the total sum number of lumbar spines were added together that were done for the past year, around 1014 (one thousand fourteen), we calculated the total actual time savings, and factored the minutes into hours, and the hours into shifts. Since the site averages ten hour shifts daily for their MRI systems, this calculated out to almost one full week of operational savings on just the improved lumbar MRI scans alone.
Here is the math below to prove what we saved on the MRI lumbar spines alone:
1) Old MRI Lumbar Study equated to seconds took 20:31 = 60 x 20 (+31) = 1231 seconds of scanning time for the old study
2) New MRI Lumbar Study equated to seconds took 17:39 = 60 x 17 (+39) = 1059 seconds of scanning time for the new study
3) 1059 /1231 = 0.860 or a difference of 14% faster
4) 1231 – 1059 = 172 seconds total difference per MRI Lumbar scan.
5) Multiply the seconds by 1014 MRI lumbar spine cases and the new number is 174408 total seconds.
6) Divide the 174408 by 60 seconds to break down into minutes, and this becomes 2906.8.
7) Divide the 2906.8 by 60 minutes to become hours and this becomes 48.44 hours.
8) Divide this into ten hours shifts, and this becomes four full days of ten hour shifts, plus one day of almost a nine hour shift.
Conclusion: Not only did the site save time on the most popular exam ordered, but they also got improved image quality to successfully compete with the local 3T that had been stealing some business.
Additionally, this created almost one full week of operational open time, reduced overtime and increased power savings in operational time.
