Comparison Study Looks at Ultrasound
A literature review of comparison studies for medical imaging methods, published in the May/June issue of the Journal of Diagnostic Medical Sonography, puts ultrasound at the top of the list for accuracy and cost effectiveness.
“Accuracy and Cost Comparison of Ultrasound Versus Alternative Modalities Including CT, MR, PET, and Angiography” reports the results of research studies that compare the accuracy and cost effectiveness of ultrasound versus other imaging modalities, such as magnetic resonance imaging (MRI), computed tomography (CT), contrast angiography (CA), and single-photon emission computed tomography (SPECT).
Alternate imaging technologies “are often considerably more expensive, include radiation exposure, are less portable, or have an increased risk of complications from contrast media,” write authors S. Michelle Bierig, MPH, RDCS, FASE, FSDMS, and Anne Jones, RN, BSN, RVT, RDMS, FSVU.
“Interestingly, the increase in spending by Medicare for alternative imaging services has been at a higher growth curve than the increase in the use of ultrasound,” the authors note.
