Brain MRF in Children, Adolescents and Young Adults With Acute Leukemia

The survival of children, adolescents and young adults (AYA) with acute leukemia has improved dramatically over the last two decades. This success is a result of using multiple chemotherapy drugs in combination, with the inclusion of drugs that enter the brain and prevent leukemia cells from growing there. Studies in these cancer survivors have shown that the exposure to these chemotherapy drugs can lead to risks for impaired brain function, also referred to as neurocognitive side effects of chemotherapy. There is an opportunity to identify participants at risk for these side effects and to prevent their development. The purpose of this study is to incorporate a brain imaging tool known as Magnetic Resonance Fingerprinting (MRF) to look for brain matter changes in acute leukemia participants receiving chemotherapy. The MRF scan will be performed at diagnosis and repeated at multiple times during the entire therapy duration as well as at defined intervals after therapy is complete. Investigators would also do an electronic test of memory and brain function (cognitive function), which would be administered in a gaming format on iPads or a similar device. The goal will be to correlate results of MRF imaging with the tests of cognitive function. The benefits of this imaging technique include that it can be done quickly (in minutes), it is non-invasive, it is resistant to motion-artifacts and it can be easily repeated for comparison purposes. The advantages of the cognitive test include its short duration of 20 minutes and its gaming format making it friendly for children to use.
