QUAMRI - Quality Assurance in Magnetic Resonance Imaging

Many people are talking about quality assurance and ISO-certification in hospitals. Implementation of the results into daily practice is part of good clinical practice.
Here we try to improve the knowledge about image quality in magnetic resonance imaging.
Typical parameters are signal to noise ratio, image uniformity, ghosting, linearity, etc. For every parameter you will find some data on the thresholds to maintain.
But do you know how images look like if one of these parameters is not within the required range?
If you search for images from MRI systems, you will typically find perfect ones or really bad ones for demonstration purposes. The ones you never (barely) achieve in the real world. But do you know what's possible with the system you use?
We hope that within some month we can provide a series of images to show the spectrum of image quality for any MRI system. If you would like to support this project, feel free to contact us
