Since its first uses in the 1950s, ultrasound has been utilized mostly in hospital settings. But with the development of less costly, portable equipment, its use has expanded to doctor's offices, trauma settings, and even to outer space. The article compares the use of ultrasound to magnetic resonance (MR) imaging, computed tomography (CT), contrast angiography (CA), and single-photon emission computed tomography (SPECT).
In addition to evaluating the accuracy and cost effectiveness of ultrasound as compared to other medical imaging techniques, the study reviewed the use of ultrasound in the following applications:
• Obstetric and Gynecological
• Disease Diagnosis
"Ultrasound provides the ability to rapidly evaluate and diagnose abnormalities throughout the spectrum of clinical medicine," write the authors S. Michelle Bierig, MPH, RDCS, RDMS, FASE, FSDMS and Anne Jones, RN, BSN, RVT, RDMS, FSVU. "Its accuracy and cost-effectiveness in a variety of applications has led to its widespread adoption and use. The utilization of ultrasound compared to the use of alternative imaging methods leads to increased cost efficiency in the diagnosis and management of patients."
