Joe has noted correctly. The technicians, nurses and allied health professionals operating the equipment are well skilled in seeing how accurate the scan is in terms of what is required and of course know generally whether the scan reveals what is either suspected or being screened for.

However, other than in a small number of types, and pregnancy ultrasound is one example, only the doctor will have the rest of the medical history to hand to interpret the results. (One extreme example being certain small breast anomalies in a 80 year old isn't a problem as no matter how bad it could get, the patient will die with it not of it so surgery would be trauma for little benefit whereas a person in their 20s would be advised to nip it in the bud.)

Some technicians can interpret and share with patients, for instance there could be guidelines to say that if it shows no anomaly and nothing else of concern, a technician may be authorised to put a mind at rest there and then. Some technicians are competent at interpreting, we have "reader" radiographers in the same way as prescribing nurses and pharmacists.

I had an MRI scan after I passed a kidney stone. All clear but my better half got their hands on it, and being in the bloody trade used a small anomaly (nowhere near the kidney) to try and bully me into cutting down on beer... Mmm.🤔
