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).

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.

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.

8 trends in radiology technology to watch in 2023

Here is a list of some key trends in radiology technology from our editors based on our coverage of the radiology market.

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.

Multiple sclerosis ribbon MS

Vascular ultrasound findings offer clues into disability progression in MS patients

These findings were largely governed by biochemical and lifestyle factors, such as diet and physical activity. They were also found to have a greater influence on disability progression than aging. 

Seno Medical's Imagio OA/US Breast Imaging System, optoacoustic ultrasound

Emerging optoacoustic ultrasound technology promises to reduce false-positives and unnecessary biopsies

Optoacoustic ultrasound can noninvasively provide valuable information on tumor behavior and better inform providers of whether a mass is benign or malignant.

ASE releases updated rheumatic heart disease guideline

The American Society of Echocardiography released a new guideline document on the comprehensive use of echocardiography in the diagnosis and therapeutic intervention of rheumatic heart disease.
