Core Tip
Core tip: In magnetic resonance imaging, the oval or round-like morphological features, particularly oval or ellipse features, are of great significance for the diagnosis of minimal-fat angiomyolipoma. Capsules, lipid composition, and washout are atypical manifestations of minimal-fat angiomyolipoma.
