In short
Ultrasound technicians (diagnostic medical sonographers) and radiology technicians both usually train through an associate degree. Sonographers earned a median of $96,590 in May 2025 and radiologic technologists $80,110, per BLS. Sonography is projected to grow faster, 13.9% through 2035. Radiology techs work with radiation; sonographers do not.

The day to day
A sonographer holds the transducer, finds the right angle and judges in the moment whether the images show what the doctor needs. It is skilled, hands-on and can strain the shoulder and wrist. A radiology tech positions patients, sets the equipment and protects everyone from unnecessary radiation, and often works in emergency departments.
Credentials
Most states license radiologic technologists, and many use the ARRT exam. Sonographers commonly earn credentials from national registries, and employers often require them.
