Upstart CT angiography eclipses cardiac MRI's rising star
"Nobody thought about doing CT angiography. It just wasn't on the radar screen, although a few proponents said, 'Don't forget about us; we're working on interesting things here in the desert.'

"We thought MR was the future. But the CT guys did one thing really well. They did an angiogram with an injection of a contrast agent, and the technology became much, much better.
"Radiologists and cardiologists basically do what they've always done, but they push a different button. And new software has it all come out in about two minutes.
"That's pretty easy compared to MR, where I have to take a course to learn cardiac MR because of the rules set down by the Society for Cardiovascular Magnetic Resonance (which I helped write).
"Why should anyone do all that when they already know how to take an x-ray picture? All they do is push a button and get the same kind of picture. That's one reason why CT angiography has a real advantage and why it is now ahead of MR angiography."

What a New Mammography Study Reveals About BMI, Race, Ethnicity and Advanced Breast Cancer Risk
December 8th 2023In a new study examining population attributable risk proportions (PARPs) based on data from over three million screening mammography exams, researchers found that postmenopausal Black women had the highest BMI-related PARP and premenopausal Asian and Pacific Islander women had the highest breast density-related PARP for advanced breast cancer.
Study: Contrast-Enhanced Mammography Changes Surgical Plan in 22.5 Percent of Breast Cancer Cases
December 7th 2023Contrast-enhanced mammography detected additional lesions in 43 percent of patients and led to additional biopsies in 18.2 percent of patients, over half of whom had malignant lesions, according to a study of over 500 women presented at the recent Radiological Society of North America (RSNA) conference.
