Intracranial Metastatic Melanoma:Correlation Between MR Imaging Characteristics and Melanin Content AJR 165:1503-1512, Isiklar,I.,et al, 1995 See this aricle in Pubmed Article Abstract Only a minority of melanoma metastases have the anticipated MR imaging findings of melanotic melanoma,which consist of high signal intensity relative to that of cortex on T1-weighted images and low signal intensity relative to that of cortex on T2-weighted images.Of tumors that do exhibit this melanotic pattern,the majority have more than 10%melanin-containing cells.The putative MR imaging pattern for amelanotic melanoma is nonspecific,as over half of tumors with this pattern contain melanin.
