Diagnostic Imaging

Radiologists use diagnostic imaging to non-invasively look inside the body to help determine the causes of an injury or an illness, and confirm a diagnosis. Providers use many imaging modalities to do so, including CT, MRI, X-ray, Ultrasound, PET and more.

Ultrasound assesses bone health similarly to DXA, study finds

Ultrasound scans of the calcaneus—or the heel bone—were equal to results gathered from dual-energy x-ray absorptiometry (DXA) for assessing bone health, according to new research published online in the March issue of The Journal of the American Osteopathic Association.

Danish researchers reported in Radiology that an artificial intelligence system was able to interpret more than 114,000 screening mammograms using a reading protocol with high sensitivity and specificity.

Can radiologists who interpret mammograms make the switch to DBT?

Radiologists who interpret traditional two-dimensional (2D) mammograms required little time in transitioning to reading digital breast tomosynthesis (DBT) exams or three-dimensional (3D) mammograms, and improved their accuracy in cancer detection, according to research published online Feb. 26 in Radiology.

SABR improves survival for early, inoperable lung cancer patients

Stereotactic ablative body radiation therapy (SABR) nearly doubled the overall survival of patients with inoperable stage I lung cancer compared to standard radiotherapy, according to results of a multi-center phase III trial published in the Lancet Oncology.

fMRI reveals nerve stimulation could ease emotional, physical pain in PTSD patients

The FDA has approved nerve stimulation for treatment of episodic and chronic cluster headaches and acute migraines. The findings, detailed in a study published online Feb. 13 in PLOS ONE, could help personalize treatment for PTSD, which according to the National Institute of Mental Health impacts roughly 3.6 percent of U.S. adults per year.

NIH-funded study IDs potential MRI biomarker for psychosis

The imaging technique has proven reliable in detecting neuron loss in people with neurodegenerative illnesses, but now can serve as a marker of dopamine function in those without neurodegenerative disorders. It also provides many advantages over conventional invasive methods or modalities requiring radiation exposure, such as PET.

CT study yields good news for children with muscle cancer

Aggressive treatment is not warranted in patients with pediatric rhabdomyosarcoma (RMS), a malignant soft tissue tumor in the muscle tissue of children, according to a multi-site analysis of CT scans published in the Journal of Clinical Oncology.

Surveillance imaging after MRI-guided breast biopsy varies by institution, radiologist

“Attempts to reduce this variation through clear guidelines and standardization may avoid confusion among referring physicians and patients, improve allocation of limited imaging resources, and reduce inconvenience to patients," wrote lead author Bhavika K. Patel, MD, of the Mayo Clinic in Phoenix, and colleagues in a recent study published in the Journal of the American College of Radiology.

Quantitative imaging of breast tumors, parenchyma may improve breast cancer diagnosis

“Because breast parenchyma may reflect the biologic risk factors associated with breast cancer development, yielding the stromal parenchyma as an indicator of precancer, the combination of parenchyma and tumor characteristics may provide a stronger predictive model of malignancy,” lead author Hui Li, PhD, and colleagues wrote in a new study published in Radiology

"Gen AI can help tackle repetitive tasks and provide insights into massive datasets, saving valuable time," Thomas Kurian, CEO of Google Cloud, said Tuesday. 

SCAI and four other major healthcare organizations signed a joint letter in support of intravascular ultrasound. 

The newly approved AI models are designed to improve the detection of pulmonary embolisms and strokes in patients who undergo CT scans.
