Advanced applications make ultrasound more competitive
November 02, 2005
Although ultrasound use in medicine continues to grow, the modality faces increasingly stiff competition from other modalities such as CT, MRI, and PET, which have undergone startling advances in the past several years. To respond to this competition, radiologists can employ several rapidly developing new technologies to enhance ultrasound's capabilities. With speckle reduction, volumetric imaging, and elastography, sonographers can reduce artifacts, improve image contrast, reduce image noise, and better gauge tissue stiffness to detect subtle hard-to-spot abnormalities. Proper use of these powerful new technologies can boost accuracy, repeatability, and efficiency to help keep ultrasound competitive with the other cross-sectional imaging modalities and perhaps open up new applications.
