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. 

FDA issues adverse event report on MRI accident as investigations into its cause continue

The FDA's description of the event aligns with prior reports speculating that the accident involved a staff member transporting a patient to an MRI suite on a hospital bed, which was allegedly sucked into the MRI bore.

New nuclear medicine treatment could potentially cure non-Hodgkin lymphoma

“If testing is successful in humans, this would represent an excellent new treatment option for patients with this disease.”

Radiologist performance has improved since the introduction of DBT for breast cancer screening

Since being approved by the U.S. Food and Drug Administration in 2011, DBT has become the most common method for breast cancer screening, and as of September 2022, 84% of all U.S. mammography screening facilities housed DBT units.

Children included in the assessment displayed several concerning neurological MRI findings shortly after their birth, including acquired microcephaly, severe parenchymal atrophy and cystic encephalomalacia. 

Example of the four types of breast tissue density. The density of fibroglandular tissue inside the breast impacts the ability to easily see cancers. Cancers are very easy to spot in fatty breasts, but are almost impossible to find in extremely dense breasts. These examples show craniocaudal mammogram findings characterized as almost entirely fatty (far left), scattered areas of fibroglandular density (second from left), heterogeneously dense (second from right), and extremely dense (far right).

Experts developed a deep learning model that can estimate breast density

When tested, the model achieved a performance comparable to that of human experts.

pulsed radiofrequency for sciatica

Pulsed radiofrequency procedure could help patients avoid surgery for sciatica

In PRF procedures, a probe is used to intermittently apply energy directly to the dorsal root ganglia, which is often where pain and neurologic symptoms associated with sciatica originate.  

Around the web

A total of 16 cardiology practices from 12 states settled with the DOJ to resolve allegations they overbilled Medicare for imaging agents used to diagnose cardiovascular disease. 

CCTA is being utilized more and more for the diagnosis and management of suspected coronary artery disease. An international group of specialists shared their perspective on this ongoing trend.

The new technology shows early potential to make a significant impact on imaging workflows and patient care.
