Ultrasound, also referred to as sonography or diagnostic ultrasound, uses high-frequency sound waves to visualize soft tissue. Ultrasounds are frequently ordered to measure fetal anatomy during pregnancy, check for blood clots and to guide needle biopsy procedures of the breast, abdomen and pelvis. The imaging modality does not use any radiation to create images. Find news specific to cardiac ultrasound (echocardiography).

PHOTO GALLERY: What does fetal medical imaging look like?

This is a clinical photo gallery of fetal imaging that explains what all can be seen on medical imaging, how sex is determined, how measurements are used to track the development of a baby and how potential issues can be diagnosed. It includes examples of fetal ultrasound, the primary imaging modality used during gestation, magnetic resonance imaging (MRI) and some rare images of fetal computed tomography (CT).

Urinary stones in the ED: What will it take for ultrasound to gain ground on costly, radiative CT?

Professional consensus supports the use of ultrasound for initial imaging evaluation of patients presenting in the ED with suspected urinary stone disease (USD). However, as of 2018, only 2% of these patients received ultrasound while some 59% had CT.

Imaging-guided treatment for carpal tunnel syndrome provides long-term relief without surgery or hospitalization

Carpal tunnel syndrome can be successfully treated without surgery, according to new findings being presented at RSNA 2022 in Chicago. The procedure typically takes just 10 to 15 minutes.

The new modality, opto-acoustic/ultrasound (OA/US) or photoacoustic (PAI) imaging, from Seno may be a game-changer. And here’s what you need to know about it, how experts see it improving the breast cancer diagnosis process, and how it’s projected to reduce the need for extra diagnostic imaging exams and breast biopsies by a lot.

Opto-acoustic Imaging: A new modality changing the future of breast imaging

When it comes to breast imaging, a few new technologies have improved the visualization of lesions and diagnostic procedures. But a new modality could change the game completely.
