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.

Study: Some MRI can do more harm than good for lower back pain

“There is a very poor relationship between changes on MRI scans and the presence or absence of low back pain," Martin Underwood, MD, a general practitioner and a professor at Warwick Medical School, told The Guardian. “If you get into the business of treating disc degeneration because it has shown up on an MRI, the likelihood is that, in most of those people, it is not contributing to their back pain.”

Purdue’s new imaging method detects blood vessel disorders, brain injuries without contrasts

Researchers have created a functional MRI (fMRI)-based analytical imaging method to detect and monitor blood vessel disorders and injuries in the brain without using invasive contrast agents.

Liquid biopsy may alter treatment of metastatic breast cancer

A new study has found that a form of liquid biopsy—circulating tumor cells (CTCs)—may be a key technique for creating a staging system to significantly alter the treatment of metastatic breast cancer (MBC).

Diffusion-weighted MRI beats PET/CT in predicting survival of cancer patients receiving radioembolization

A group of German researchers found diffusion-weighted (DW) MRI provided superior prognostic information compared to PET/CT in liver cancer patients who underwent 90Y radioembolization and proved more accurate in predicting overall survival in these patients.

fMRI may improve predictions of cognitive decline in MS patients

Using functional MRI (fMRI), researchers from VU University Medical Center in Amsterdam found a correlation between white matter brain damage and atrophy in multiple sclerosis (MS) patients—a primary factor of cognitive impairment in patients with the disease.

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.
