A literature review published in the May/June issue of Journal of Diagnostic Medical Sonography (JDMS) compared ultrasound imaging with other diagnostic medical imaging modalities including contrast angiography, single-photon emission computed tomography (SPECT), magnetic resonance imaging (MRI) and computed tomography (CT).
The authors, S. Michelle Bierig, MPH, RDCS, RDMS and Anne Jones, RN, BSN, RVT, RDMS, wrote “The terms sonography and ultrasonography are often used synonymously with ultrasound, but the term ultrasound is the most widely used term in the published literature. This literature review uses the term ultrasound (US) because that term is overwhelmingly used in the references reflected in this article.”
In addition to evaluating the diagnostic accuracy and cost effectiveness of sonography as compared to other medical imaging methods, the study reviewed the use of ultrasound in specific clinical applications including OB/GYN, abdominal, vascular and cardiac imaging. The use of sonography in emergency medicine, disease diagnosis and cancer care was also reviewed.
The authors concluded that "The utilization of ultrasound compared to the use of alternative imaging methods leads to increased cost efficiency in the diagnosis and management of patients."
