From: Differentiation of periapical granulomas and cysts by using dental MRI: a pilot study
Example images of two periapical cysts (radiographs, dental MRI and histopathology). Histopathological results: a radicular cyst; b odontogenic keratocyst. On MRI, both cysts show a well-defined outer margin (arrow heads) without soft tissue involvement, a thin peripheral rim with a homogeneous contrast-enhancement in T1wFS+C (open arrows), and a homogeneous texture of the lesion center in T2wFS (straight arrows). Note the identical MRI features of the radicular cyst and the keratocyst. T2wFS T2- weighted with fat saturation, T1wFS+C T1-weighted with fat saturation+contrast agent, (s) subtraction, cor coronal, ax axial, parasag parasagittal
