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.

Ramon Varcoe explains the LIFE-BTK trial for the Abbott Esprit fully bioresobable scaffold at TCT23.

Fully bioresorbable stents boost care for CLI patients in LIFE-BTK trial

Ramon Varcoe, MBBS, co-principal investigator for the LIFE-BTK trial, discussed the results with Cardiovascular Business at TCT 2023. "I can't wait to start using these in my patients. It's going to make a huge difference."

Shimadzu Medical Systems USA released the latest version of its Trinias angiography system at the Radiological Society of North America (RSNA) 2022 meeting to address radiation concerns and to help improve workflow.
 

Radiation and workflow concerns addressed in new Shimadzu angiography system

To address radiation concerns by interventionalists and to help speed workflows in cath labs, Shimadzu released new AI features and single button push features for table and C-arm movement. 

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.

Use of ultrasound to guide needles used for femoral vascular access for cath lab procedures can help reduce bleeding and vascular complications. But the Universal Trial at TCT 2022 showed no difference. Image courtesy of Sonosite

Ultrasound guidance for femoral access did not reduce bleeding or vascular complications in TCT late-breaker

The UNIVERSAL Trial, one of the largest multicenter randomized trials comparing ultrasound with fluoroscopic guidance vs. fluoroscopic guidance alone, found there was no reduction in major vascular access complications. 

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.

The imaging iodine contrast shortage is delaying procedures and causing rationing at hospitals. impact is it having on hospitals and the tough decisions that are being made to triage patients to determine if they will get a contrast CT scan or an interventional or surgical procedure requiring contrast.

Alan H. Matsumoto, MD, chair of the department of radiology at the University of Virginia and vice chair of the American College of Radiology Board of Chancellors, explains the contrast shortage situation and the tough decisions providers are being forced to make.

Alan H. Matsumoto, MD, chair of the department of radiology at the University of Virginia, vice chair of the American College of Radiology (ACR) Board of Chancellors, and chairman of the ACR Commission on Interventional and Cardiovascular Radiology, explains that the iodine contrast shortage has led to use of MRI gadolinium contrast agents in some cases.

Around the web

Several key trends were evident at the Radiological Society of North America 2024 meeting, including new CT and MR technology and evolving adoption of artificial intelligence.

Ron Blankstein, MD, professor of radiology, Harvard Medical School, explains the use of artificial intelligence to detect heart disease in non-cardiac CT exams.
