Typical magnetic resonance imaging (MRI) involves taking many images called 'contrasts' to look at the body in different ways. Standard scan settings are usually good enough for a radiologist to review. The best settings often change with the age of the patient and their health, and are time consuming to determine. Quantified imaging is an alternative to contrast-based imaging which explicitly measures tissue properties and can be used to create almost any contrast. This method of imaging has been held back by a lack of the right software. Synthetic MR Technologies has created a quantified imaging solution - SyMRI - to enable radiologists to acquire quantified images and always obtain the best contrast images.~The objective of this study is to evaluate SyMRI in a pediatric population to determine if Sickkids would be interested in purchasing this product / support Health Canada approval. Specifically, the investigators are interested in determining if SyMRI is clinically useful:~Is synthetic imaging quality comparable / better than conventional imaging?~Qualitative - Are radiologists more confident using synthetic MR vs conventional~Quantitative - Signal-to-noise (SNR) and Contrast-to-noise (CNR)~To what extent can total exam times be reduced?~Is the software user friendly and would investigators use it?
