How Pigs Could Help People Who Need Liver Transplants
In this study, eGenesis scientists used CRISPR to make not one, but 69 edits to the pig genome: three to remove the most pig-like proteins that would activate the human system to reject the liver, seven edits to add human genes to the pig liver, and 59 to inactivate pig retroviruses that could cause problems in humans. “Until CRISPR, there was no way to do that many edits easily,” says Curtis.
The future of pig livers
This single-patient study is just the beginning of what xenotransplants can achieve, says Shaked. The liver has two major duties in the body: regulating critical enzymes and substances such ...

Wider use of cardiac PET faces challenges
Strategies to increase the use of cardiac PET myocardial perfusion imaging (MPI) in the U.S. include education, advocacy, and industry partnerships, according to a study published January 10 in the Journal of Nuclear Cardiology.
Cardiac PET MPI has emerged as a key tool for diagnosing and managing patients with cardiovascular diseases, especially coronary artery disease, yet overall it remains underutilized in the U.S., noted Rupa Sanghani, MD, of Rush University Medical Center in Chicago, and colleagues.
“With combined and focused effort, we can ensure that cardiac PET is widely recognized and utilized as a valuable t...

FDA clears 4DMedical CT LVAS lung function scanning software
The U.S. Food and Drug Administration (FDA) has given 510(k) clearance to 4DMedical for CT LVAS, its advanced lung function imaging software.
CT LVAS software processes existing CT scans using sophisticated algorithms derived from aerospace technology. The software measures lung ventilation in tens of thousands of locations in the lungs. The Regional Ventilation Visualizations provide region-specific ventilation at deep inspiratory breath hold for a midcoronal slice and three axial slices (upper, middle, and lower).
The regional ventilation data is quantified in lung volume change and regional lung ventilation heterogene...

3D CT reconstruction shows ties to malignant pulmonary nodule growth
3D reconstruction of CT images could aid in follow-up strategies for pulmonary nodule screening, a study published November 15 in the Journal of Cardiothoracic Surgery found.
Researchers led by Wenfei Xue from Hebei Province General Hospital in Shijiazhuang, China, found through such reconstruction that the tumor blood vessel diameter of ground-glass opacity (GGO) lesions are tied to the growth of malignant pulmonary nodules.
“The identification of ground-glass nodule (GGN) growth is a complicated task,” Xue and co-authors wrote. “However, the pulmonary nodules growth with GGO can be predicted by considering the cl...

Noninvasive cardiac imaging tests lead to lower downstream costs
Noninvasive cardiac imaging tests lead to reduced downstream costs, and stress echocardiography may be the go-to modality with this in mind, according to Canadian research published November 14 in the Journal of the American Society of Echocardiography.
A team led by Idan Roifman MD, from the University of Toronto found that stress echocardiography led to an 18% reduction in costs, while cardiac CT angiography (CCTA) and myocardial perfusion imaging led to the highest downstream costs.
“These findings may help inform testing decisions in chest pain patients,” Roifman and colleagues wrote.

Road to RSNA 2023: Digital X-Ray
This year’s trip along the Road to RSNA for digital x-ray features mileposts mostly set by AI research. Models will be proposed for applications ranging from predicting bone density on chest x-rays to generating complete reports on anterior cruciate ligament (ACL) tears. Yet several presentations to be given at the meeting reminded us that issues concerning basic elements of x-ray technology remain highly important, as well as whether imaging access is equitable in the "real-world."In one, a group at the University of Washington in St. Louis asked, “How much ionizing radiation are neonatal patients exposed to during ...

How cardiac interventional radiographers promote better patient outcomes
Chris Schmidt.Cardiac interventional (CI) radiographers play a vital role in the diagnosis and treatment of patients during their procedure in the cardiac catheterization laboratory. They are skilled healthcare professionals who specialize in using imaging technology and minimally invasive procedures to diagnose and treat various cardiac and vascular conditions. CI radiographers work closely with radiologists, vascular surgeons, and interventional cardiologists to perform procedures such as angioplasty, stent placement, heart perfusion studies, and more. These procedures are often used to open blocked blood vessels, repair...
