T1RESS (T1 relaxation in steady state at contrast gain)

2020: The announcement of 3D technology - visualization which improves visibility of a tumor of a brain at MRT

At the end of October, 2020 researchers from Northwestern University provided a new method of three-dimensional visualization which improves visibility of a tumor of a brain on MRT to Chicago.

The new method which received the name of assessment T1 relaxation in steady state at contrast gain (T1RESS) uses radio waves and magnetic fields for generation of signals of MRT differing from applied earlier. This technique allows to improve visualization of a tumor that is especially useful at diagnosis of very small malignancies.

There was a new 3D technology - visualization which improves visibility of a tumor of a brain at MRT

The improved visibility of edges of a tumor at such scanning can increase the accuracy of surgical intervention and radiation therapy, so, improve results of treatment, - the chief researcher Robert Edelman considers.

The research included 54 patients with tumors of a brain and showed that T1RESS increases contrast between tumors and normal tissue of a brain twice in comparison with the existing MRT methods. Edelman compares effect of T1RESS with the advent of stars in the night sky:

The contrast between stars and the day sky is insufficiently high that we could see them. The same can be told about the tumors invisible on normal MRT. T1RESS doubles contrast between tumors and normal tissues of a brain therefore it becomes much simpler to detect malignancies.

If advantages of T1RESS are confirmed in further researches, the new technique can be implemented easily in clinical practice thanks to a packet of specialized software. Researchers already submitted the application for registration of the patent and in the future are going to study a possibility of use of a new method at diagnosis of a breast cancer and a prostate.^[1]
