a. Negative case for active inflammatory sacroiliitis on MRI illustrated with one of its coronal STIR images. There are no hyperintense foci at the subchondral bone adjacent to the articular surfaces (white arrowheads). b. A positive example of bone marrow edema related to active sacroiliitis on MRI. The subchondral bone marrow edema is characterized by ill-defined foci of hyperintensity and is shown inside the dotted white circle. White arrowheads indicate the right sacroiliac joint surface
