Deep Learning in Cardiovascular Magnetic Resonance
I am a deep learning (machine learning) scientist, with expertise in CMR, and cross-domain knowledge of cardiovascular diseases, MR physics and scan protocols. I work on the interpretation and enhancement of gadolinium-free native CMR modalities, particularly quantitative T1-mapping, using novel artificial intelligence approaches. My recent research focus has been on AI Virtual Native Enhancement imaging, where we develop AI techniques that could serve as "virtual contrast dye" to replace intravenous contrast dye. This work has been funded by the John Fell Fund and British Heart Foundation Centre of Research Excellence.
I also work actively on CMR T1-mapping standardisation. T1-mapping offers a unique opportunity for myocardial tissue characterization. However, for clinical sites attempting to implement T1 mapping, it is often unclear how to validate the methods correctly before using them for clinical diagnosis. We have developed a robust and practicable phantom quality assurance approach to assure the accurate installation of CMR T1-mapping methods. The programme aims to translate T1-mapping into widespread use in a real-life setting.
