The BME 600 seminar series is an opportunity to practice the presentation skills BME graduate students will need for the defense of their thesis, or for presentation of their research at scientific meetings. It is also a forum where you will learn to critically review the scientific and presentation skills of your peers.
Next Upcoming Seminar:
Date: 2019 December 4
Time: Noon - 1PM
Location: ECHA L1-220
Presentation Topic: “Bloch Modelling Enables Robust T2 Mapping using Retrospective Proton Density and T2-weighted Images from Different Vendors and Sites
Presenter: Gitanjali Chhetri, Dept. of Biomedical Engineering
The combination and comparison of data across multiple sites and vendors is essential for large group MRI studies, and for testing the robustness of clinical methods. However, the reliability of data derived from multiple sites relies on pulse sequence equivalence. In particular, standard T2 mapping from multiple spin echoes is highly dependent on the refocusing flip angles and transmit field homogeneity, when an exponential fit is used. However, modelling of the pulse sequence with knowledge of the refocusing angles can yield accurate T2 values by accounting for the effects of stimulated echoes.
A common approach to T2 mapping is the use of a dual-echo proton density (PD) and T2-weighted imaging sequence. Here we examine T2 mapping variation for a multi-site brain MRI study using both standard exponential fitting and Bloch-ISEC modelling. We show that Bloch simulation based Indirect and Stimulated Echo Compensation minimizes these differences in T2 maps across different scanners. In contrast, standard exponential fitting results in highly variable T2 values across MR systems even if echo and repetition times are identical.
All are welcome!
