This plenary session will provide a broad overview of real-time MR imaging, including the history of its development, technological basis, and clinical applications.

Educational Objectives
Upon completion of this course, participants should be able to:
-Summarize the history of real-time MRI from its initial developments to the state-of-the-art;
-Describe the pulse sequences, reconstruction algorithms, and computing and display technologies that enable real-time MRI;
-Discuss the current technological limitations of real-time MRI;
-Identify common diagnostic applications of real-time MRI (e.g., cardiac, speech, MSK);
-Identify common interventional applications of real-time MRI (cardiovascular, guided biopsy, HIFU);
-Hypothesize technical advances that could further improve the capabilities of real-time MRI; and
-Hypothesize clinical applications that could benefit from the capabilities of real-time MRI.

Real-Time MRI Technology

Real-time MRI is the ability to continually acquire high temporal resolution data. Technological advances which have enabled high temporal and spatial resolution real-time MRI, include; i) hardware improvements; ii) efficient acquisition strategies (non-Cartesian trajectories and data undersampling); iii) reconstruction algorithms (parallel imaging, temporal encoding, Compressed Sensing), iv) rapid reconstruction (data reduction and parallelization on GPUs). 

Diagnostic Real-Time MRI

This talk will summarize several diagnostic applications of RT-MRI. Within cardiac imaging, I will show examples of left ventricular function, valvular flow, shortening exam time, and the very common setting of arrhythmia.  Within joint motion imaging, I will show examples assessing instability in the wrist joint and temporomandibular joint.  In the upper airway, I will show examples assessing airway anatomy and function during speech production and sleep-disordered breathing. Finally, I will provide some reflections on the opportunities and barriers for increased adoption of diagnostic RT-MRI.
