Ultrasound Technician Career Paths
Ultrasonogarphy is increasingly being used in clinical diagnostic settings and quickly replacing other radiologic methodologies. X rays have deleterious effects on tissues that are being exposed to them. They are also ineffective when keen imaging of fluid and tissues are needed. So ultrasound offers the advantage of being a safe procedure while providing detailed images of tissues that can aid in the diagnostic process. Commonly, the picture conjured up when ultrasound technician is mentioned is one that performs ultrasound testing on fetuses, which is just the tip of the iceberg. Due to its non-invasive nature, ultrasonography has a wide range of uses that go beyond monitoring the growth of a fetus. Even the smallest facets of anatomy can be analyzed to create an image both for diagnosis and understanding complex mechanisms of function.
Diagnostic medical sonographers may dedicate themselves to one or more of specialized disciplines within ultrasound technician career path. The specializations include
- Abdominal sonography, which deals with studies of the spleen, liver, pancreas and gall bladder
- Obstetric and gynecologic sonography, dealing with the female reproductive system
- Cardiac sonography, involving the study of muscle tissue in the heart
- Vascular sonography, involving analysis of blood flow in veins and arteries
- Neurosonography, that deals with studying brain tissue
- Breast sonography, that is focused on analyzing breast tissue and
- Ophthalmologic sonography that studies eyes
Abdominal ultrasound technicians study the conditions that require the imaging of the spleen, bile duct, gall bladder, kidneys and pancreas. Note that lungs cannot be analyzed with sonography as sound waves produce poor echoing patterns with gases and bones.
Obstetric and Gynecologic Sonography
Ultrasound technicians that specialize in obstetrics and gynecologists create and analyze images of the fetus and the female reproductive system. The ultrasound tech performs calculations of head circumference, length of tibia among others and prepares a report for the physician who will then discuss the details and prognoses with the patient. This is helpful in finding birth defects and abnormal growths in pregnant women. Conditions such as the thickness of the lining of the uterus along with monitoring ovulation also fall under the purview of what an obstetric sonographer will do.
Performing echocardiograms which is the study of heart tissue and functioning is the primary role of the cardiac ultrasound technician. The blood flow through and around the heart are used to diagnose heart conditions. Real-time imaging using Doppler ultrasound is used to study the real time functioning of the heart. An in-depth analysis of the heart valves and muscle tissue are vital in diagnosing cardiac conditions.
Vascular ultrasound technicians are valuable in the examination of complex veins and arteries resulting in the diagnosis of abnormalities or diseases such aneurisms and peripheral arterial disease. Conditions of the veins of the upper and lower extremities that cause pulmonary embolisms are also an integral part of vascular sonography. Detecting blockages or coagulations through vascular sonography is a common use for patients with clotting issues.
Neurosonographers study diseases of the central nervous system. Nervous system blood vessels are examined in order to diagnose stroke and brain aneurysms. Neurosonography is particularly useful in diagnosing neurological disorders in premature infants. Conditions that cause stroke such as sickle cell anemia are detected by Neurosonography. The transducers and frequencies employed are different for neursonographers than abdominal ultrasound techs for instance.
Breast ultrasound technicians examine tissues of the breast to detect abnormalities and disease. These tests are referred to as mammograms, but these tests are limited in that they can only detect inconsistencies in identifying whether the inconsistency is solid or fluid. Beyond this point, a needle biopsy might have to be performed to determine if the abnormality is benign or malignant. Ultrasonography is used to guide the needle to its target tissue. Once retrieved the cells are studied under the microscope to detect malignancy if present.
Opthalmologic ultrasound technicians are used to study eyes. Prosthetic lenses are inserted in the eye with the guidance of Ultrasonography. This allows for accurate measurements. Since the eye and the region surrounding the eyes are mostly fluid and muscle tissue, ultrasonography is a valuable instrument in detecting separated retinas, blood supply interruptions and other diseases of tissues surrounding the eye. Here the transducers are much smaller and specially designed for study of the eye.
