Present when you're having the scan done. They're probably off-site at a reading room somewhere. It's exceedingly difficult for me to talk to a radiologist, even when I'm the one who ordered the scan

As a general rule of thumb, if someone is operating equipment they are not a doctor, they are a tech. Radiologists don't do X-rays CTs or MRIs. They read them off-site. Doctors don't give chemo, nurses do. Etc. Etc

The exception is surgeons and anesthesiologists, who are barely doctors 😉
