3D aids coronary stent planning
Restenosis following stent placement to open a clogged coronary artery happens with alarming frequency.
A contributing factor may be improper placement of the stent.
Two software packages designed to make stent placement more precise and reduce patients' exposure to x-rays and contrast media were introduced in late September at the Transcatheter Cardiovascular Therapeutics (TCT) conference in Washington, DC.
Images created with the Philips' Allura 3D-Coronary Angiography (left) and Siemens' Interventional Cardiac 3D software (right) demonstrate the exact size and shape of diseased coronary vessels. Legends built into the displays indicate the orientation of the blood vessels relative to the cardiac cath systems. Quantitative measurements of the vessel wall can also be displayed.
Siemens' IC3D was shown as a commercial product, having cleared the FDA in July. Philips' Allura 3D-CA was still in FDA review at the start of the conference.
Philips' new software works with the company's latest digital cardiac cath system, the Allura Xper FD20, but it is also compatible with Philips' cardiac equipment built around image intensifiers. Siemens' IC3D product is being paired with the company's Axiom Artis digital cardiac cath system.
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.
