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.

Patient questionnaires improve rads’ reads for abdominal pain

Abdominal radiologists make more complete and precise diagnostic reads, and are more confident in their diagnoses, when they’re armed at the reading station with clinical information supplied by patients via questionnaire, according to a study published online June 24 in Abdominal Radiology.

No measurable gadolinium in children’s brains even after multiple doses

Gadolinium-based contrast agents (GBCAs) in the macrocyclic category have proven safe enough in children to be considered the standard of care across pediatrics whenever contrast-enhanced MR imaging is indicated, according the authors of a European study published online June 21 in Radiology.

Nimble MRI compares well with established PET-CT in dementia neuroimaging

Practical and noninvasive, MRI with arterial spin labeling may substitute for PET-CT with the radiotracer 18FDG, which requires intravenous injection, for imaging the brains of patients with suspected early-stage dementia.

Anti-anxiety medications change the brain

Benzodiazepines—the family of popular sedatives that includes Valium, Xanax and such—seem to bring about structural changes in the brain, according to a European study running in the August edition of Psychiatry Neuroimaging.

Elevated amyloid proves a warning sign of cognitive decline to come

People with elevated amyloid levels in the brain but no signs of cognitive decline are indeed more likely to develop impairment down the road, potentially leading to full-on Alzheimer’s, according to a study published online June 12 in JAMA.

In English autopsy study, heart imaging has 92% accuracy finding cause of death

Pathologists and radiologists at the University of Leicester in the U.K. have shown that postmortem CT with targeted coronary angiography (PMCTA) is capable of replacing most traditional autopsies performed in England and Wales following deaths by natural causes.

Cranial ultrasound a gentle, accurate choice for imaging infants with suspected skull defect

An Italian study published online June 3 in Child’s Nervous System shows that cranial ultrasound is a highly specific and sensitive first-step choice for imaging infants who show signs of craniosynostosis. That’s the birth defect in which the plates of the skull fuse too early, causing abnormal head shape and potentially putting injurious pressure on the brain.

Survey: Rad residency programs must sharpen efforts to draw women, engage med students

New female doctors applying for residency openings in radiology have different reasons for doing so than their male peers, and their priorities may challenge residency-program directors who’ve been trusting the conventional wisdom on things like work-life balance trumping career goals.

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.
