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.

AAA detection gets boost from commercially available AI algorithm
The opportunistic screening helps identify patients in need of monitoring and/or intervention without disrupting workflows.
AMA resolution backs expanded low-dose CT screenings for lung cancer, heart risk
Dana Smetherman, MD, CEO of the American College of Radiology, discusses the policy, which urges for more robust promotion of low-dose CT as a public health tool.
First AI-enabled POCUS app for detecting pleural effusion and atelectasis earns FDA clearance
The apps are embedded into the Exo Iris transducer, which can be plugged directly into a smartphone, utilized anywhere and without the internet.
Symptom-detected breast cancers more likely to require mastectomy, chemotherapy
New research adds to the “strong evidence” supporting screening guidelines and highlights the importance of women adhering to clinical recommendations.
3 industry partnerships, 1 clinical aim: Enriching the global supply chain of medical isotopes
Nuclear medicine operations may soon enjoy steadier flows of certain in-demand radioisotopes. If so, much credit will go to companies that had the strategic sense to collaborate with each other.

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

MRI beats ultrasound at grading common foot injury, but tables turn for up-or-down diagnostics

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.

Cardiac implantable electronic devices can be safely reprogrammed to MRI-safe mode via remote operator

In 209 study participants, the remote reprogramming resulted in a successful, event-free MRI scan for every patient.

There were several point-of-care ultrasound (POCUS) systems on display by vendors at ACC 2022. Here are two of them.

FDA greenlights portable, wearable 3D breast POCUS

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

Most states' breast cancer screening plans do not comply with USPSTF guidelines

Of the 51 plans, just 31% were consistent with the USPSTF recommendations pertaining to the starting age and frequency of screening women who are at average risk of developing breast cancer.

Major teaching hospital finds half its on-call abdominal ultrasounds call utilization into question

The investigators encourage radiologists to consider the numbers and take steps to “reinforce their gatekeeper function” to help cut ultrasound overutilization.
