About this trial

The goal of this clinical trial is to find out if new Magnetic Resonance Imaging (MRI) computer software will:

* help make scans and exams faster * reduce artifacts * make MRI easier to understand * allow technicians to focus more on the participant and less on the scanner

Participants will complete one brain MRI imaging session, lasting about 60 minutes.

Treatments tested in this trial

  • Brain MRI

    Device

    90 participants will undergo a 60 minute SOC brain MRI followed by 15 minute spiral MRI

  • Brain MRI - SOC and spiral

    Device

    6 participants will be scanned using 2 versions (SOC and spiral) pf 6 sequences (12 scans total).

  • Brain MRI - spiral

  • Brain MRI - SOC and spiral

    Device

    10 participants will be scanned using 2 versions (SOC and spiral) of 6 sequences (12 scans total).

  • Brain MRI - spiral

    Device

    10 participants will be scanned with 3 spiral sequences to achieve desired signal to noise ratio (SNR).

Trial outcomes

Primary outcomes

1

Image quality - decreasing scan time

Participants will be scanned using 2 versions (standard and spiral) of 6 sequences (12 scans total). For each sequence pair, scan time will be sped up. Image quality will be compared between the 2 versions.

Time frame
60 minutes
2

Image quality - tau

Measuring whether image quality is sufficient for routine diagnostic interpretation - specifically robustness to artifacts. The independent variable is a scanning parameter called tau, which researchers want to be long (because it makes the total scan time shorter). Researchers will compare the value of tau between SOC imaging and spiral. They will use a 5-point Likert scale to compare, where 1= undiagnostic (unacceptable), 2 = spiral scans slightly worse than SOC but acceptable, 3= spiral scans same as SOC (acceptable), 4= spiral scans slightly better than SOC (acceptable), 5=spiral scans much better than SOC (acceptable).

Image quality - consistent scan time

Participants will be scanned using 2 versions (standard and designed) of 6 sequences (12 scans total). Scan time will remain the same for each pair. Radiologists will compare each pair for differences in image quality using a 5-point Likert scale where 1= A much worse than B, 2=A slightly worse than B, 3=A comparable to B, 4=A slightly better than B, 5=A much better than B. A=new spiral scans and B=SOC scans.

Signal to Noise Ratio (SNR)

Measuring the SNR in images, by measuring the signal strength in the image and the calculated noise in those images and taking the ratio. Researchers will compare this SNR to that which their methods predicted.

Time frame
