CT versus MRI: The simplest distinguishing factors between these tests is what shows up well. With CT, bone shows up in nice detail, whereas in most MRI protocols, the bone is essentially poorly imaged. Another difference is that a CT is actual radiation exposure and an MRI is not. For the sinuses, typically, a CT is the preferred imaging modality, because you need to see the bony detail.

In most: cases, CT is preferred, due to its superior delineation of bone detail versus MRI. Variations in the bony structure of the sinuses are often responsible for predisposing to sinusitis.
