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).

Predictive model uses 6 ultrasound features to differentiate between benign and malignant thyroid nodules
Once the model is further validated, it could help guide providers in determining how to manage thyroid nodules.
Which exam is best for supplemental imaging of women with dense breast tissue?
It is widely agreed that women with dense breast tissue should undergo supplemental imaging in addition to their routine mammogram screening, but the jury is still out on which modality is best for cancer detection in this group.
CDC investigating outbreak linked to contaminated ultrasound gel used in image-guided procedures
Authorities issued three recommendations for radiologists related to the issue, including avoiding the use of nonsterile US gels.
Cardiac ultrasound contrast completely safe, despite reports to the contrary

New FDA-cleared algorithm could improve fetal anomaly detection on ultrasound

The module helps automate the detection of eight common fetal anomalies using seven routine ultrasound views of the heart, brain and abdomen.

Ultrasound 'microjets' enable targeted treatment of neurological conditions

It can be difficult to deliver targeted therapy to the brain due to its protective barrier, which only allows certain nutrients and oxygen to pass through.

Risk prediction algorithm slashes number of unnecessary thyroid nodule biopsies

Although the vast majority of nodules are benign, many are referred for biopsy as a precaution to rule out malignancy.

20-minute ultrasound-guided procedure could cure hypertension

Hypertension caused by unilateral aldosterone-producing adrenal adenomas is curable by laparoscopic removal of the entire adrenal gland, but the invasiveness and recovery time can deter patients from the treatment.
