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.

Be prepared: IV contrast media shortage could last up to 8 weeks

All formulations and concentrations of GE Healthcare’s Omnipaque (iohexol) are expected to be in short supply until mid-June due to COVID lockdowns where the contrast is manufactured.

The Woven Endobridge (WEB) device to seal wide-neck intracranial bifurcation aneurysms.

Off-label use of WEB device effective for sidewall aneurysms

A new study published in Radiology found that mesh plugs that are traditionally used to treat brain aneurysms where the blood vessels branch out can also be effective when used to treat aneurysms on the side of the vessel.

Interventional radiologists and residents highlight optimal features of IR training programs

Recent interviews sought to reach beyond the current core competency requirements to gauge how training can better prepare IR residents for real-world practice.

Stroke thrombectomy outcomes similar between radiologists, fellowship-trained neurointerventionalists

Increased volume has led to stress among endovascular stroke physicians, with some hospitals relying on interventional rads to relieve the strain.

The newly approved PET radiotracer is expected to improve patient care significantly. “We have been able to reach the pinnacle of myocardial perfusion imaging with flurpiridaz," one expert said.

GE HealthCare's flurpiridaz, the PET radiotracer that recently received FDA approval, offers several key benefits over SPECT. Jamshid Maddahi, MD, discussed the details in an exclusive interview. 

Ultrafast MCE could go on to become a go-to treatment option for obstructive coronary artery disease, according to the authors of a new first-in-human clinical study.
