The T2 SIR of chrRCC is intermediate and overlaps with ccRCC and pRCC [ 5 ]. Inside the kidneys are small working parts called nephrons. A short T2 means that the signal decays very rapidly. T2 scans are the opposite--they highlight watery tissue as white/bright and fatty tissue as dark--although it can be way more complicated than that. This implies that the lesion is benign rather than cancerous. Hyperdense cysts measuring >3 cm in diameter are also Category IIF lesions.
