Sonographer vs. Cardiovascular Technologist: Schools, Careers

The Diagnostic Medical Sonographer and the Cardiovascular Technologist have a lot in common because they are in the same profession and industry. Both use medical imaging equipment that emits high-frequency sound waves to assess patient soft tissues, organs and blood flow. The primary difference between the two professions is that the technologist dealing with the cardiovascular system has specialized in assessing the heart and artery/vein systems. This articles also includes a list of accredited cardiovascular technologist schools with programs in invasive cardiovascular technology, noninvasive vascular study, cardiac electrophysiology, pediatric echocardiography and adult echocardiography.

What are Duties of the Diagnostic Medical Sonographer?

Diagnostic Medical Sonographers are also called Ultrasound Technicians or Ultrasonographer and usually report to radiologists. The health professionals manage the following duties on any typical day:

  • Manage the workday schedule to ensure patients are allowed adequate time for procedures
  • Review physician orders and available patient information, such as other images or medical tests completed in the past
  • Consult with patients concerning patient history and special medical issues
  • Explain the procedure to patients and address concerns like physical limitations
  • Position patient in procedure room to ensure high quality, error-free results
  • Operate ultrasound equipment, adjusting controls as necessary to obtain ideal images and correct data
  • Evaluate exam results to ascertain required information was obtained and to determine if outcomes indicate additional testing is necessary
  • Record test results and other relevant medical information into electronic health records system or completing required paperwork, or both
  • Calibrate and maintain equipment
  • Consult with radiologist or other medical professionals


What is a Cardiovascular Technologist: Job Description and Duties

A Cardiovascular Technologist, sometimes referred to as a Cardiac Sonographer, uses imaging technology to detect medical issues concerning the heart and vascular system. A person can choose to train for invasive procedures to assist physicians with medical procedures like balloon angioplasties, whereas the Diagnostic Medical Sonographer does only non-invasive procedures. A technologist is different from a technician. The technologist performs a higher level of patient duties because the professional is qualified to do certain invasive procedures. The Cardiovascular Technologist usually reports to a cardiologist.

The Cardiovascular Technologist can either conduct or assist physicians with procedures like cardiac catheterizations, electrocardiograms, lung capacity test, and pulmonary function tests. In some medical settings, the Cardiovascular Technologist may assist physicians in operating rooms when they are inserting pacemakers or stents or doing open heart surgery. The technologist’s primary role as a physician’s assistant during invasive procedures is to monitor critical patient equipment. When performing cardiac or vascular related procedures, the professional may need to use ultrasound equipment to document blood flow or to look for abnormalities.

The typical duties include the following:

  • Consult with patients to collect and document medical history
  • Explain procedures to patients, easing worries and concerns
  • Position patient in the testing room in preparation for procedure
  • Attach electrocardiogram (EKG) electrodes to patient and operate equipment to monitor patient heart rate and rhythm during diagnostic procedure
  • Assist with insertion of catheters during invasive procedures, including preparing area where catheter will be inserted
  • Assist physician during imaging procedure by operating equipment controls to ensure ideal images are obtained
  • Monitor patient during the procedure, watching for signs of discomfort or other issues the physician should be made aware of


Sonographer Salary vs. Cardiovascular Technologist Salary

Per the U.S. Department of Labor, the 2014 mean annual wage for Diagnostic Medical Sonographers was $68,390. This is compared to $55,210 for Cardiovascular Technologists. However, the salary figures may be a bit deceptive at first glance because technologists and technicians are included in the cardiovascular specialty salary figures. There is a greater likelihood of ultrasound specialties earning higher than the average wages. More than 50 percent of ultrasound specialists concentrating on imaging and care of the adult heart earn more than the average salary. Specialization combined with experience can greatly increase earning power.

Educational Requirements: Sonographer vs. Cardiovascular Technologist

Students have several educational program choices if they wish to become a Diagnostic Medical Sonographer. People currently working in a health field, or who have past experience in healthcare, could earn a certificate in Diagnostic Medical Sonography by completing a one-year program. Other options include earning an Associate’s Degree in Diagnostic Medical Sonography or a Bachelor’s Degree in Diagnostic Medical Sonography. Ideally, students will attend CAAHEP accredited schools which are available in every state and consists of classroom and clinical instruction. CAAHEP refers to the Commission on Accreditation of Allied Health Education Programs.


The Cardiovascular Technologist completes a specialized cardiac sonography program that also includes didactic and clinical instruction. After completing the programs in cardiovascular technologist schools, the graduates are eligible to sit for exams offered by the American Registry of Diagnostic Medical Sonographers (ARDMS). There are several exams offered for credentialing as a Registered Diagnostic Medical Sonographer (RDMS), a Registered Cardiac Sonographer (RDCS), and a Registered Vascular Technologist (RVT).

Some states require Cardiovascular Technologists doing invasive procedures to be licensed and will recognize certain credentials for licensing purposes. Another credentialing organization is Cardiovascular Credentialing International (CCI), which is recognized by prestigious organizations like the American College of Cardiology, the Society of Diagnostic Medical Sonography, and many others. CCI offers certification as a Registered Cardiovascular Invasive Specialist (RCIS), in addition to registration as a Registered Cardiac Sonographer (RCS) or a Registered Vascular Specialist (RVS).

  1. Alana Crain says


    I’m interested in becoming an ultrasound technician but not quite sure the best route is to go as far as education? I have an Associate’s in an unrelated field and have no healthcare experience. When I was younger I wanted to go into the medical field but was also passionate about the arts so went that direction. Being older and worrying about job security, I’ve decided to take a completely opposite career path. I’ve always wanted to do something in healthcare but couldn’t quite pinpoint what I wanted to do and after lots of research, sonography seems to be the best fit for me. However, I’m quite confused on how to go about education. Looking into Accredited programs, there are different prerequisites. Do I do a two year program and get an Associate’s in sonography or should I continue with a Bachelor’s since I have some college background? I just want to take the right path to get into a great program once I’ve completed the prerequisites. Thanks in advance for any help, thought or insight!
