You make a comparison with dentistry. Monitoring a patient when you are next to them is one thing, but it’s quite another to monitor a patient in another room with equipment that can’t contain wires and is running cables at 10ish metres long. Sedation adds about 50% more time to a scan and anaesthetics doubles or quadruples scanner time while also adding the cost of anaesthetics, prep and recovery, which is huge. Doing scans without sedation is preferable. On a well run MR, patient change over is 1-2 minutes. Coil setup takes longer and varies between scans but for 20 minutes of imaging I’d expect bookings to be 30 minutes. The 20 minutes doesn’t include pauses between scans, SAR cool down and sequence prep time (which are all hard limits and staff can’t really improve them).
