Recently, GE Healthcare reported a series of supply interruptions in iodinated contrast media, specifically iohexol (Omnipaque) and iodixanol (Visipaque). These agents are used in computed tomography (CT) scans, X-rays, interventional radiology and in cardiac catheterization. The supply of radiopharmaceuticals is stable. Stress nuclear cardiac studies, such as SPECT and PET, are often clinically appropriate alternatives for patients who are scheduled for CT angiography. IV iodinated contrast agents are needed for CT angiography but are not needed for noncontrast CT for calcium scoring.
In the midst of last month's shortages of the imaging agent 99mtechnetium-pyrophosphate (PYP), ASNC has maintained close contact with PYP manufacturers on the status of market supply, including anticipated effects of ongoing interruptions and delayed availability of raw material. PYP manufacturer Curium, which released PYP to customers in March, has notified ASNC that PYP is available but the market remains unstable. Curium will be restricting orders until the market supply stabilizes.
March is Cardiac Amyloidosis Month, and ASNC is highlighting creative ways members are raising awareness of this condition among people who may not have heard of it but could be at risk.
