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).

Deep learning and rads comprise an ‘efficient pipeline’ for detecting, classifying thyroid nodules

Competing to classify thyroid nodules on ultrasound images as either malignant or benign, three deep learning models have essentially drawn a tie with four radiologists.

DL networks augment radiologist performance for thyroid cancer detection

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.

AI model could open doors for greater access to obstetric ultrasound

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. 

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.

Experts suggest new follow-up imaging protocols for vaccine-related lymphadenopathy

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

O-RADS externally validated for differentiating between benign and malignant ovarian lesions

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

AI boosts performance of novice nurses when assessing pregnant patients via ultrasound

Using a handheld probe and smartphone, nurse midwives were able to estimate gestational age as accurately as certified sonographers.


 

Algorithm performs at expert level when distinguishing between benign and malignant ovarian tumors

Experts involved with the study suggested that these findings could be beneficial in the future of ovarian tumor assessment by providing clinical decision making support.
