Introduction

In the last decade, one of the most fascinating advancements in the field of neuroimaging has emerged: the development of multiband or simultaneous multi-slice scanning. This innovative technology has revolutionized the way we acquire MRI data, significantly speeding up the process while maintaining high-quality imaging.

Traditional Functional MRI (fMRI)

Typically, MRI data is acquired in slices through the head. During a standard functional MRI sequence, it would take approximately three seconds to scan through the entire head, capturing about 64 slices to form a complete brain volume. This process, while effective, can be time-consuming.

The Innovation at University of Minnesota

Researchers at the University of Minnesota implemented a groundbreaking approach that challenged the conventional methods. They realized that instead of acquiring one slice at a time, it is possible to capture multiple slices simultaneously—two, three, or even four slices at a time.

Methodology

To achieve this, the researchers exploited the known features of the receiving coils used to gather MRI data. By understanding these characteristics, they could effectively separate the signals from different slices acquired simultaneously. This innovation not only reduced the scanning time significantly but also maintained the integrity and accuracy of the data.

Conclusion

Simultaneous multi-slice scanning represents a significant leap forward in neuroimaging technology. This advancement enhances the efficiency of MRI scans, opening new possibilities for faster and more detailed brain imaging.
