Prevalence and risk factors of perirenal hyperintensities on T2-weighted MR imaging.

Objectives: To assess the prevalence and severity of perirenal hyperintensities (PRHs) on T2-weighted magnetic resonance imaging (MRI) and their risk factors in the general population.

Methods: 1752 participants (910 women, 842 men, median age: 52 years) of the Study of Health in Pomerania were included. A visual classification system was established to assess the severity of PRHs (stage 0: no PRHs visible to stage 3: extensive PRHs visible).
