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. 

"Our model is a potential tool to improve the primary trisomy 21 screening based on ultrasonographic images for universal clinical application," experts involved in the study suggested.

Men with prostate cancer can avoid many of the unpleasant side effects of chemo, surgery and radiation therapy when they are treated with high-intensity focused ultrasound instead.

Whole-body imaging reveals clinically undetectable blood clots in patients after their first dose of AstraZeneca's COVID vaccine.

Researchers recently completed an external validation for the Ovarian-Adnexal Reporting and Data System (O-RADS) for classifying lesions as malignant or benign, for which validation had been previously lacking. #ORADS

The study yielded a malignancy rate of 8.4% for the women who presented for routine pelvic ultrasound without prior suspicion for adnexal lesions.

DiA Imaging Analysis, which specialized in developing the AI-based automated cardiac ultrasound solution LVivo Seamless. The technology is now integrated through partnerships with dozens of healthcare vendors, including ScImage, GE Healthcare, Philips Healthcare Konica Minolta and IBM Watson.

Artificial intelligence vendor DiA has emerged as a key third-party provider of AI to larger imaging vendors.

The new technique is still in the development stage, but early research suggests it could provide clinicians with a new treatment option for breaking down arterial plaque. 

The GE healthcare vScan Air was one of several point of care ultrasound (POCUS) systems on display at the ACC 2022 meeting.

There were several point-of-care ultrasound (POCUS) systems on display by vendors at ACC 2022. Here are two of them.

After being presented with more than 15,000 images, each DL network yielded results comparable to that of four seasoned radiologists, authors of a new EJR study said.

Experts have developed an artificial intelligence model that can estimate gestational age with accuracy that rivals that of formally trained sonographers completing fetal biometry scans. 

Don't delay mammograms after COVID vaccine. Women do not need to delay their mammogram appointment after COVID-19 vaccination. An example of COVID vaccine caused axillary adenopathy. The woman has a family history of breast cancer, but this lesion, seen on breast ultrasound, tested negative in an RSNA study.  Women should not wait to get a mammograms after COVID vaccines.

New research shows that persistent lymph node swelling observed on imaging can persist beyond 12 weeks post-vaccination for up to 50% of women.

Researchers recently completed an external validation for the Ovarian-Adnexal Reporting and Data System (O-RADS) for classifying lesions as malignant or benign, for which validation had been previously lacking. #ORADS

In addition to O-RADS external validation, experts also sought to determine if incorporating acoustic shadowing as a benign finding would improve diagnostic performance.

Arl Van Moore, MD, American College of Radiology (ACR) delegate to the American Medical Association House of Delegates, former ACR president, chairman of the ACR Board and former CEO of Strategic Radiology, discusses radiology-related policy decisions at the AMA 2022 meeting.

The American Medical Association Board of Delegates approved a policy calling on payers to reimburse for the drug regadenoson and not to employ payment policies that push for cardiologists to change the drug they use for pharmacologic stress for one that is considered less safe.

Researchers presented their proposed design of a self-collimating SPECT system at SNMMI 2022.
