As with personal protective equipment (PPE), infant formula, and toilet paper, the COVID-19 pandemic continues to cause supply chain disruptions—this time causing an Omnipaque shortage. The contrast dye shortage has resulted in reduction and/or delays of the availability of Omnipaque (Iohexol) and Visipague (Idixonal).
These contrast dyes are needed for some imaging tests, including computed tomography (CT scans), which are often used to help diagnose tumors, investigate internal bleeding, or check for other internal injuries or damage and computed tomography angiography (CTA scans), often used in emergency cases, including diagnosis of strokes, aneurysms, and for cardiovascular procedures. During imaging tests, the dyes create contrast in body parts and fluids, making it easier to read scans and diagnose illness and conditions.
