Diagnostic Medical Sonographers and Cardiovascular Technologists and Technicians

Summary

What Diagnostic Medical Sonographers and Cardiovascular Technologists and Technicians Do About this section

Diagnostic medical sonographers use high-frequency sound waves to produce images of the inside of the body.

Diagnostic medical sonographers and cardiovascular technologists and technicians operate special equipment to create images or conduct tests. They work closely with physicians and surgeons, who view the images and test results to assess and diagnose medical conditions.

Duties

Diagnostic medical sonographers and cardiovascular technologists and technicians typically do the following:

• Prepare patients by explaining the procedure to them and answering their questions
• Prepare exam rooms and maintain diagnostic imaging equipment
• Properly situate patients for imaging
• Operate equipment to obtain diagnostic images or to conduct tests
• Review images or test results to check for quality and adequate coverage of the areas needed for diagnoses
• Analyze results for abnormalities and other diagnostic information and provide a summary of findings to physicians
• Record findings and keep track of patients’ records

Diagnostic medical sonographers specialize in creating images, known as sonograms or ultrasounds, that depict the body’s organs and tissues. Sonography is often the first imaging test performed when disease is suspected.

Sonography uses high-energy sound waves to produce images of the inside of the body. The sonographer uses an instrument called a transducer to scan parts of the patient’s body that are being examined. The transducer emits pulses of sound that bounce back, causing echoes. The echoes form an image on a computer that physicians use for diagnosis.

The following are examples of types of medical sonographers:

• Abdominal sonographers specialize in imaging a patient’s abdominal cavity and nearby organs, such as the kidney, liver, gallbladder, pancreas, and spleen. Abdominal sonographers may assist with biopsies or other examinations requiring ultrasound guidance.
• Breast sonographers specialize in imaging a patient’s breast tissue. Sonography can confirm the presence of cysts and tumors that may have been detected by the patient, the physician, or a mammogram. Breast sonographers assist with procedures that track tumors and help to provide information that will aid physicians in making decisions about treatment options for breast cancer patients.
• Cardiac sonographers (echocardiographers) specialize in imaging a patient’s heart. They use ultrasound equipment to examine the heart’s chambers, valves, and vessels. An echocardiogram may be performed either while the patient is resting or after the patient has been physically active. Cardiac sonographers also may take echocardiograms of fetal hearts so that physicians can diagnose cardiac conditions during pregnancy.
• Musculoskeletal sonographers specialize in imaging muscles, ligaments, tendons, and joints. These sonographers may assist with ultrasound guidance for injections, or during surgical procedures, that deliver medication or treatment directly to affected tissues.
• Pediatric sonographers specialize in imaging of children and infants. Many of the medical conditions they image are associated with premature births or birth defects. Pediatric sonographers may work closely with pediatricians and other caregivers.
• Obstetric and gynecologic sonographers specialize in imaging the female reproductive system. For example, many pregnant women receive sonograms to track the baby’s growth and health.
• Vascular technologists (vascular sonographers) create images of blood vessels and collect data that help physicians diagnose disorders affecting blood flow. Vascular technologists often evaluate blood flow and identify blocked arteries or blood clots.

Cardiovascular technologists and technicians create images and conduct tests involving the heart and lungs. The following are examples of types of cardiovascular technologists and technicians:

• Cardiovascular invasive specialists, also known as cardiac catheterization technologists or cardiovascular technologists, monitor patients’ heart rates and help physicians in diagnosing and treating heart problems. They assist with cardiac catheterization, which involves threading a catheter through a patient’s artery to the heart. They also prepare and monitor patients during open-heart surgery and during insertion of pacemakers, defibrillators, and stents. Technologists may prepare patients for procedures by shaving and cleansing the area into which the catheter will be inserted and by administering topical anesthesia. During the procedure, they monitor the patient’s blood pressure and heart rate.
• Cardiographic or electrocardiogram (EKG) technicians specialize in EKG testing. EKG machines monitor the heart’s performance through electrodes attached to a patient’s chest, arms, and legs. Tests record heart metrics while the patient is at rest or is physically active, such as walking on a treadmill.
• Pulmonary function technologists monitor and test patients’ lungs and breathing. For example, they use a spirometer to measure how much and how fast patients can inhale or exhale. These technologists help physicians in diagnosing and treating problems of the pulmonary system.

How to Become a Diagnostic Medical Sonographer or Cardiovascular Technologist and Technician About this section

Cardiovascular education programs typically include a clinical component in which students work in a medical facility.

Diagnostic medical sonographers and cardiovascular technologists and technicians typically need formal education, such as an associate’s degree or a postsecondary certificate. Employers may require or prefer that workers have  certification.

Education

High school students who are interested in medical sonography or cardiovascular technology should take classes in anatomy, physiology, physics, and math. EKG technicians may qualify for entry-level jobs with a high school diploma or the equivalent.

Colleges and universities offer both associate’s and bachelor’s degree programs in sonography and in cardiovascular technology. One-year certificate programs also are available from colleges and some hospitals.

Sonography and cardiovascular education programs usually include courses in anatomy, medical terminology, and applied sciences. Instruction in sonography programs generally  corresponds to the relevant certification field, such as abdominal sonography or breast sonography. Cardiovascular programs include coursework in either invasive or noninvasive procedures. Programs also typically include a clinical component in which students earn credit while working under the direction of an experienced technologist in a hospital, a physician’s office, or an imaging laboratory.

Licenses, Certifications, and Registrations

Employers may prefer to hire diagnostic medical sonographers and cardiovascular technologists and technicians who have professional certification, or they may expect applicants to earn certification shortly after being hired. For payment purposes, insurance providers and Medicare may stipulate that a certified sonographer, technologist, or technician perform certain procedures.
