Medical Imaging

Physicians utilize medical imaging to see inside the body to diagnose and treat patients. This includes computed tomography (CT), magnetic resonance imaging (MRI), X-ray, ultrasound, fluoroscopy, angiography,  and the nuclear imaging modalities of PET and SPECT. 

With the shortage, which pertains specifically to all formulations and concentrations of GE Healthcare’s Omnipaque (iohexol), expected to last until mid-June, several organizations have eluded that conservation efforts are of critical importance.#contrastshortage #CTcontrast #iodinatedcontrast
