MRI-based radiomics boosts triple-negative breast cancer detection

Example of various breast MRI protocol sequences that offer different types of soft tissue enhancement. Imaging performed on a Siemens Magnetom system. Breast MRI can help see through dense breast tissue to better detect cancers. #densebreasts #Breastdensity #BreastMRI

"The present study validated the feasibility of using MRI-based radiomics to identify a disease prone to missed diagnosis and misdiagnosis," experts involved in the study said.

Diffusion-weighted MRI boosts detection of locally recurrent pancreatic cancer

A. Axial contrast-enhanced CT image shows 1.7 cm lesion (arrow) with ill-defined margin at left side of superior mesenteric artery. B. On axial T2-weighted image, mass is hyperintense to paravertebral muscle (arrow). C. On arterial phase post-contrast T1-weighted image, mass shows mild enhancement (arrow) compared to unenhanced image; enhancement pattern classified as early. D. On DWI with b-value of 800 mm2/s, mass is hyperintense (arrow) to paravertebral muscle. E. On ADC map, mass is visually hypointense (arrow) to paravertebral muscle. Findings indicate presence of qualitative diffusion restriction; lesion ADC value was 0.96 × 10−3 mm2/s. F. Axial image from CT performed 6 months after MRI shows increase in lesion’s greatest axial diameter by more than 5 mm (arrow), indicating soft tissue abnormality represents locally recurrent tumor.

MRI with DWI images showed higher sensitivity in detecting local recurrence after PDAC resection.

AI helps novice medical assistants perform high-quality echocardiograms

Novice medical professionals perform diagnostic quality echocardiograms with AI guidance 

 

Point-of-care ultrasound users are shown by where to put the probe and how to move it to perform optimal echocardiograms using the UltraSight artificial intelligence (AI) software. The goal is to reduce variability between sonographers and increase diagnostic quality of the images.

In a blind pilot study, inexperienced users successfully captured images for 100% of patients using AI guidance.

ACR working with FDA and HHS to help address imaging contrast shortage

The American College of Radiology (ACR) announced this week its government relations staff has been engaging federal agencies in an effort to improve product availability and hasten resolution of the ongoing iodine contrast shortage.

VIDEO: American College of Radiology working with FDA to mitigate contrast shortage

Interview with Alan H. Matsumoto, MD, FSIR, FACR, FAHA, professor of radiology, chair of the Department of Radiology at the University of Virginia, vice chair of the American College of Radiology (ACR) Board of Chancellors, and the chairman of the ACR Commission on Interventional and Cardiovascular Radiology. He explains how the ACR and group purchasing organizations are asking the FDA to mitigate the contrast shortage with an emergency use authorization (EUA) to allow non-FDA cleared iodine contrast use.
