Medical Imaging

Physicians utilize medical imaging to see inside the body to diagnose and treat patients. This includes computed tomography (CT), magnetic resonance imaging (MRI), X-ray, ultrasound, fluoroscopy, angiography, and the nuclear imaging modalities of PET and SPECT.

New iron-based imaging agent significantly improves brain tumor visualization
Ferumoxytol is used primarily in medications that treat anemia, but the FDA recently cleared it for deployment in brain imaging as well.
AI reduces readers' kidney lesion interpretation times by over 30%
The tool also can be used on contrasted abdominal scans completed for other clinical indications, addressing suspicious lesions before they worsen.
Nvidia sees major shift in radiology to AI agents and new autonomous imaging systems
“Physical AI agents being able to actually deliver some of these services—all the way into robotic surgery—this is where we're going to see this next chapter of medicine be written,” said Kimberly Powell, vice president and general manager of healthcare at Nvidia.
Scoring system outperforms standard radiology reports for predicting soft tissue tumor malignancy
The Soft-Tissue Tumor Reporting and Data System (ST-RADS) is an MRI framework that was designed to assess the risk of soft tissue tumors and help providers in managing the finding.
Mindfulness improves brain connectivity, MRI data show
Mindfulness-based stress reduction techniques combine meditation, bodily awareness exercises and yoga to temper stress and anxiety.

Women 75 and older don’t benefit from screening mammograms

Researchers analyzed Medicare claims data on more than 1 million women ages 70 to 84 to reach their conclusions.

FDA hosts 2-day workshop focused on AI, medical imaging

As AI continues to make a profound impact on the medical imaging industry, the FDA is hosting a two-day public workshop to discuss the benefits and risks of this powerful technology.

PET, CT combine to shorten tuberculosis treatment times

"We hope that the tool will one day enable clinicians to determine the most effective doses of specific drugs in specific patients, so as to further optimize the treatment of infectious diseases," investigators of the new trial wrote in Nature Medicine.

CT detects coronavirus abnormalities before symptoms appear, reveals new clinical finding

The study details the first case of associated bilateral pleural effusions in an individual with lab-confirmed COVID-19.

Cigna labels most hospital-based CT, MR imaging ‘not medically necessary’

The nation’s fourth largest private payer detailed a small list of exceptions, including if a patient is less than age 10 or has a contrast agent allergy.

MRI predicts ‘frozen shoulder’ in rotator cuff tears

Two imaging findings—specifically, joint capsule swelling and thickness at the recess of the armpit—are useful to predict shoulder stiffness in patients with this particular injury.

Chest CT yields higher sensitivity than lab testing standard for diagnosing coronavirus

Chinese researchers published a new case set of 51 patients with confirmed COVID-19, and found chest CT's sensitivity was much greater than real-time polymerase chain reaction lab testing.

AI entered the arena, clocked radiology—and the fight is still on

A funny thing happened on the way to the printer with this issue of RBJ. In an email exchange, a radiologist who’d spoken with one of our reporters let me know he had more to say on the combustible subject about which he’d been interviewed.
