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).

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.

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.

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.

A figure from the 2022 CAD non-invasive imaging guidelines showing a comparison of computed tomography angiography (CTA) and a SPECT-CT vs. an invasive angiogram from the cath lab showing the same blockage in a coronary artery.

New multi-society recommendations highlight role of non-invasive imaging in evaluating coronary artery disease

A new, multi-society document, "Non-Invasive Imaging in Coronary Syndromes," focuses on how multiple imaging techniques can evaluate different aspects of coronary artery disease (CAD), all without the need for invasive angiograms.

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

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.

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.

Imaging suggests blood clots are more common in COVID than pneumonia

In a recent study, venous thromboembolisms were detected in those with COVID via multiple imaging modalities at a rate of 16.3% compared to 9.2% in individuals with CAP.

These ultrasound features predict ovarian cancer

Doctors created a simple system that categorizes adnexal lesions as classic or nonclassic to streamline the process of ovarian cancer risk stratification.

Automated AI-generated measurements combined with annotated CT images can improve treatment planning and help referring physicians and patients better understand their disease, explained Sarah Jane Rinehart, MD, director of cardiac imaging with Charleston Area Medical Center.

Two advanced algorithms—one for CAC scores and another for segmenting cardiac chamber volumes—outperformed radiologists when assessing low-dose chest CT scans. 

"Gen AI can help tackle repetitive tasks and provide insights into massive datasets, saving valuable time," Thomas Kurian, CEO of Google Cloud, said Tuesday.
