Description of intervention(s) / exposure
This study is a data collection study for the purposes of training software algorithms.

Participants who have recently received an head MRI as part of their routine care will receive two emu™ brain scans. emu™ device brain scans measure the dielectric properties of the brain using non-invasive, non-ionising, low-energy, electromagnetic pulses.

During an emu™ brain scan procedure, the emu™ is brought bedside to a participant lying supine on a hospital bed. A headset housing an array of antennae is placed on the head, where the headset membrane inflates with a coupling fluid to conform to the shape of the head during which the scans take place.

Participation in this study consists of a single visit taking place in the hospital following the MRI brain scan. Each visit takes up to one hour and consists of two scan procedures conducted by a qualified nurse or physician, taking ten minutes each. Nurses and physicians responsible for conducting scans will receive two hours of face-to-face training or refresher training with EMVision trainers one week prior to enrolment of the first participant. All scan data is reviewed by EMVision engineers to verify scanning procedures are conducted to an appropriate standard.

Study participation is considered complete following the second emu™ brain scan; no follow-up visits or reporting is required.

Comparator / control treatment
Participants will act as their own control. The comparator MRI scan and its associated duration is at the determination of the participants’ physicians, typically approximately 30 minutes; this study does not require any additional interventions to their standard-of-care MRI.
