Interventional Imaging

A subspecialty of interventional radiology (IR) uses image-guided, minimally-invasive procedures to diagnose and treat various diseases. Interventional radiologists rely on angiography, mobile C-arm and fluoroscopy imaging systems to perform thrombolysis, embolization, biopsies, vascular and other minimally invasive procedures, which can reduce recovery time, risk and costs.

Intermittent fluoro method reduces radiation dose during image-guided biopsy

And the method does not come at the expense of diagnostic yield, an uptick in adverse events or increased procedure times.

Costs of PE interventions are frequently physician-dependent

“Without a clear reference standard technique that optimizes patient outcomes, device selection is based on availability and physician-driven selection, which can substantially impact procedural costs,” authors of a new cost analysis in Clinical Radiology stated.

Newly approved radiation protection system said to reduce exposure by 90%

The U.S. Food and Drug Administration’s latest radiological clearance should come as welcome news to radiologists and cardiologists who perform interventional procedures.

Is stopping antithrombotic therapy prior to image-guide breast biopsy really necessary?

Experts arrived at this conclusion after comparing incidents of hematoma between patients who did and did not receive antithrombotic therapy prior to their procedure.

Researchers examine growth of nonphysician practitioners in radiology

A new paper in the Journal of the American College of Radiology digs into the emergence of physician assistants and nurse practitioners in radiology and how it has impacted clinical and procedural volumes and imaging interpretation.

Do image-guided corticosteroid injections impact COVID risk?

Patients who received an injection had an infection rate of 2.2% at 4-month follow-up. In comparison, the infection rate for the general population in Massachusetts was 7.5% during the same period.

25% of patients undergoing transthoracic needle biopsy experience complications

Higher complication rates were observed in inpatient settings and in patients with COPD. Also associated with increased adverse events were prior lung cancer screening and the use of oral anticoagulants or antiplatelets.

A comparison between a traditional iodine contrast angiogram (left), and a gadolinium contrast angiogram (right). MRI gadolinium contrast is starting to be used in some interventional radiology procedures and is being considered in interventional cardiology due to the iodine contrast shortage.

Gadolinium can be used as substitute for iodine contrast in some interventional imaging procedures

Gadolinium might be an alternative, stop-gap solution for interventional procedures during the current iodine contrast shortage.

Automated AI-generated measurements combined with annotated CT images can improve treatment planning and help referring physicians and patients better understand their disease, explained Sarah Jane Rinehart, MD, director of cardiac imaging with Charleston Area Medical Center.

Two advanced algorithms—one for CAC scores and another for segmenting cardiac chamber volumes—outperformed radiologists when assessing low-dose chest CT scans. 

"Gen AI can help tackle repetitive tasks and provide insights into massive datasets, saving valuable time," Thomas Kurian, CEO of Google Cloud, said Tuesday.
