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.

CT for breast-cancer metastasis can do what nuke bone imaging does—and for less

In staging advanced breast cancers for bony metastasis, CT of the thorax, abdomen and pelvis can effectively replace nuclear bone scans in facilities where both exams together are currently considered optimal. The CT-only approach stands to save money and, presumably, reduce patient stress.

Around the web

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

"I see, at least for the next decade, this being a SPECT and PET world, not one or the other," explained Tim Bateman, MD.

The FDA-approved technology developed by HeartFlow can predict a patient's long-term risk of target vessel failure as well as more invasive treatments performed inside a cath lab.
