Imaging modalities and physics mnemonic

Pairing MRI contrast and CT contrast

The mnemonic

Gado for MRI, Iodine for CT

What each word stands for

  • GadoGadolinium, paramagnetic MRI contrast
  • IodineIodinated contrast used in CT and angiography

Why it matters clinically

Avoids giving the wrong contrast and flags the risks: nephrogenic systemic fibrosis with gadolinium, contrast nephropathy with iodine.

Where it stops being reliable

Does not cover contrast-free techniques or other agents such as barium and microbubbles.
