Join us in this enlightening episode of the Zone 3 Podcast as we delve deep into the world of MRI parameters with our guest expert, Matt Rederer, To find out what we really are doing when change certain parameters. This video is a comprehensive guide to understanding and optimizing MRI parameters for the best image quality
Video Chapters:
Introduction [0:00 - 1:00]
Opening of the topic and the guest, Matt.
Understanding TR (Repetition Time) [1:01 - 10:00]
Explanation of TR and its impact on T1 contrast in the image.
Discuss the importance of finding the "sweet spot" for TR to achieve the best image quality.
Understanding TE (Echo Time) [10:01 - 20:00]
Explanation of TE and its role in controlling T2 contrast.
Discussion on how a higher TE will result in more signal loss, affecting the contrast.
Understanding TI (Inversion Time) [20:01 - 30:00]
Explanation of TI and its role in an inversion recovery sequence.
Discussion on how TI is used to nullify the signal from certain tissues, enhancing the contrast between different tissues.
Understanding ETL (Echo Train Length) [30:01 - 40:00]
Explanation of ETL and its role in a fast spin echo sequence.
Discussion on how a longer ETL can speed up the scan but may also result in more image blurring.
Understanding Flip Angle [40:01 - 50:00]
Explanation of the flip angle and its role in MRI.
Discussion on how the flip angle can affect the contrast and signal-to-noise ratio of the image.
Understanding Diffusion Weighted Imaging [50:01 - 60:00]
Discussion on the role of the B value in diffusion-weighted imaging.
Explanation of how a higher B value will result in more diffusion weighting, but also more noise in the image.
Understanding Phase Contrast Imaging [60:01 - 70:00]
Discussion on the role of the VENC (Velocity Encoding) value in phase contrast imaging.
Explanation of how the VENC value needs to be adjusted based on the velocity of the flow being imaged to avoid aliasing artifacts.
Conclusion [70:01 - End]
Recap of the main points discussed in the video.
Closing remarks and end of the video.
This video covers key MRI parameters including TR, TE, TI, ETL, and Flip Angle. We also delve into the intricacies of Diffusion Weighted Imaging and Phase Contrast Imaging.
Whether you're an MRI professional or a student in the field, this video is a valuable resource for enhancing your understanding of MRI parameters and their impact on image quality.

About our Guest:
Matt is the President of RITE Advantage LLC. A company focused on educating and testing MRI, CT, Sonography, and Radiography students and technologists. The lead MRI technologist and a certified MR Safety Officer at Advocate Sherman Hospital. Matt is also the MRI/CT Physics Professor at Elgin Community College.
Matt’s very knowledgeable at MRI physics which is the fundamental factor for image acquisition. So in addition to tricks and tips learned from coworkers, Matt stresses the importance of understanding how to optimize the image you’re acquiring by means of physics. Matt appreciates the artistic influence that naturally comes with photography. If you understand what’s happening on the back end in terms of k space etc., then you can be the creator of new tips and tricks to share with your coworkers and team.
