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. 

Internal medicine researchers have developed a three-year learning track to train select residents in all things point-of-care ultrasound. 

Point-of-care ultrasound instruction that is less than comprehensive risks boosting trainees’ perceptions of relative proficiency without building their objective expertise in image interpretation.

A nonprofit healthcare-certification organization is challenging every user of medical ultrasound in the world to become proficient and certified in the modality by 2030.

Complex renal cysts or solid renal masses appear in 13% to 27% of individuals who receive abdominal imaging.

Upon training a machine learning model to analyze ultrasound images of the neck, researchers tested their algorithm and have found it correctly flagged likely cancerous nodules of the thyroid gland at a 97% clip.

Testing AI’s ability to detect carotid artery disease on ultrasound, U.K. researchers have found their algorithm achieved 90% accuracy, along with 87% sensitivity and 82% specificity, at the task.

Two European studies illustrate opportunities and challenges presented by the growing appeal of point-of-care ultrasound to primary care practices.  

Using point-of-care ultrasound in emergency settings does not lead to overutilization of follow-up imaging with cross-sectional CT, MRI or additional ultrasounds. 

Foot ultrasound bested foot MRI on pooled sensitivity while lagging on specificity

Injuries of the plantar plate—the cluster of ligaments underneath the four smaller “knuckles” of the toes—are better assessed with MRI than with ultrasound scans. 

The patient wears the device while the machine essentially operates itself.

American Society of Nuclear Cardiology (ASNC) delegates to the American Medical Association (AMA) House of Delegates 2022 meeting Stephen Bloom, MD, and Nishant Shah, MD, explain a new AMA policy asking Congress to revise its clinician decision support mandate. 

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.

American Medical Association President Gerald Harmon, MD, joined us for an exclusive chat about some of the hottest topics discussed at the 2022 AMA House of Delegates meeting.
