Ultrasound

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).

As artificial intelligence (AI) adoption expands in radiology, there is growing concern that AI algorithms needs to undergo quality assurance (QA) reviews. How to validate radiology AI? How can you validate medical imaging AI?

Cardiologists use video-based AI model to ID coronary artery disease

A team of specialists out of Cedars-Sinai developed the deep learning model using TTEs from nearly 3,000 patients.

New 'vortex ultrasound' tool shows promise for treating blood clots

The "vortex ultrasound" technique eliminates blood clots with helical ultrasound waves, rather than forward-facing waves.

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.

Automated breast ultrasound (ABUS) allows for reproducible breast imaging without variation based on which sonographer performs the exam. It also can help centers were they are short on qualified breast sonographers.  Breast ultrasound can help identify cancers, or benign cysts, even in women with very dense breast tissue. At the GE Healthcare booth at RSNA.

Commercially available AI systems excel in cancer detection in dense breasts

A multi-modal AI approach can combine information from both ABUS and DM, which could be especially beneficial in resource poor regions where experienced radiologists might not be readily available.

kid child pediatric MRI imaging

Number of kids needing sedation prior to imaging drastically drops following intervention

At one institution, the intervention resulted in an average cost savings of $139,367.80 per year.

transesophageal echocardiography (TEE)

Simulations help 'accelerate the TEE learning curve' for cardiology trainees

Simulation-based training can help cardiology fellows improve their TTE abilities, even when instructors or equipment are in short supply.

Google Health develops AI models for more accurate gestational age estimation

The models do not require manual measurements from a sonographer to estimate GA. Instead, they are able to make use of ultrasound images and videos.
