Ultrasound Testing

DUTIES

Diagnostic medical sonographers (Ultrasound Techs) operate special imaging equipment that uses high-frequency sound waves to create images of the interior of the human body. The images and test results help physicians assess and diagnose medical conditions. In fact, ultrasound sonograms are often the first imaging tests performed when disease is suspected.

• Prepare patients for procedures by taking their medical history and answering any questions about the procedure.
• Prepare and maintain diagnostic imaging equipment.
• 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.
• Recognize the difference between normal and abnormal images, and identify other diagnostic information.
• Analyze diagnostic information to provide a summary of findings for physicians.
• Record findings and keep track of patients' records.

The sonographer uses an instrument called an ultrasound 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 are then sent to an ultrasound machine, which processes them and displays them as images used by physicians for diagnosis.

Ultrasound Specialization

Cardiac sonographers (echocardiographers) specialize in imaging a patient's heart. They use ultrasound equipment to examine the heart's chambers, valves, and vessels. The images obtained are known as echocardiograms. 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. Cardiac sonographers work closely with physicians or surgeons before, during, and after procedures.

Pediatric sonographers specialize in imaging 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. 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.

Obstetric and gynecologic sonographers specialize in imaging the female reproductive system. Many pregnant women receive sonograms to track the baby's growth and health. Obstetrical sonographers work closely with physicians in detecting congenital birth defects. Sonography can confirm the presence of cysts and tumors that may have been detected by the patient, the physician, or a mammogram.

EDUCATION

Diagnostic medical sonographers need formal education, such as an associate's degree or a postsecondary certificate. Employers prefer graduates of programs accredited by the Commission on Accreditation of Allied Health Education Programs (CAAHEP). Colleges and universities offer both associate's and bachelor's degree programs in sonography, while one-year certificate programs may be available from selected hospitals.

Sonographic Imaging Techniques focuses on developing the practical skills needed to perform ultrasound scans effectively. Students learn various imaging techniques, such as abdominal, obstetric, gynecological, vascular, and echocardiographic examinations. Emphasis is placed on proper scanning protocols, patient positioning, and image optimization.

Hands-on clinical Clinical Internship: experience is essential for ultrasound students to apply theoretical knowledge in real-world settings. Under the supervision of experienced sonographers and physicians, students practice scanning techniques, interact with patients, and participate in the diagnostic process.

CERTIFICATION

The ARDMS offers ultrasound certificates in Abdomen, Breast, Echocardiography, Neurosonology, OB/GYN, Vascular Technology, Musculoskeletal Sonography. The Commission on Accreditation of Allied Health Education Programs (CAAHEP) accredits thousands of health science education programs in the US. If you graduate from a school accredited by the CAAHEP, you’re automatically qualified to sit for the ARDMS exam. In order to earn certification from the ARDMS, individuals must take the Sonography Principles & Instrumentation (SPI) examination.

The ARDMS (American Registry for Diagnostic Medical Sonographers), formed under Inteleos, is a non-profit organization established in 1975. Worldwide, over 90,000 medical professionals have been certified by the ARDMS, representing a variety of specializations including cardiac, vascular, and OB/GYN sonography. ARDMS is accredited by several prestigious and reputable bodies, including the International Organization for Standardization (ISO), National Commission for Certifying Agencies (NCCA) and the American National Standards Institute (ANSI).

QUALITIES FOR SUCCESS

Ask yourself if you can see yourself being an ultrasound tech, having daily contact with patients who may be elderly, ill, or recovering from surgery. Other patients may have physical or emotional disabilities, which can be challenging. While classes and internships will prepare you well, certain innate qualities that you bring to bear will help you succeed.
