How Can I Work in Health Diagnostic and Treatment Services?


A bachelor's degree in allied health technologies with a concentration in nuclear medicine, respiratory care, vascular technology or diagnostic medical sonography may help you prepare for a job in health diagnostic and treatment services. In addition to completing a general education core, you'll take courses in anatomy and physiology, biology, chemistry, physics and medical terminology. To fulfill the requirements for your area of concentration, you may also study radiography and imaging.

Required Skills

Physical stamina is key to working as an allied health professional, since you'll spend most of your time on your feet, working under stressful conditions in hospitals and health clinics. Reliability, the ability to follow instructions and communication skills are also important in this field.


While additional credentials for diagnostic and treatment services professionals are often voluntary, the BLS states that many employers prefer to hire those who have earned professional certification. Requirements include completion of a program accredited by the Commission on Accreditation of Allied Health Education Programs (CAAHEP) or the Joint Review Committee on Education in Radiologic Technology (JRCERT), as well as a passing score on an exam.

For example, if your area of specialization is cardiology technology, you may seek certification from the American Registry of Diagnostic Medical Sonographers (ARDMS) or Cardiovascular Credentialing International. A career in diagnostic medical sonography may benefit from a Registered Diagnostic Medical Sonographer credential.

If you choose to specialize in vascular and breast sonography, then you should seek credentials through the American Registry of Radiologic Technologists (ARRT). Although requirements can vary from state to state, most radiologic technologists need to be licensed; voluntary certifications are also available from the ARRT.
