On MR imaging, most renal masses are hypointense on T1 and hyperintense on T2, thus comparison between T1-weighted image pre and post intravenous injection of contrast readily shows variable degree of hyperintensity of the lesions due to contrast enhancement (particularly hypervascular ones). Before symptoms of kidney cancer are noticeable, a laboratory test or an imaging study may reveal a possible diagnosis. On MRI, the oncocytoma is usually a well-circumscribed mass that is T1 hypo- or isotense relative to the renal cortex and exhibits variable T2 heterogeneity.

Renal masses are usually seen as subtle, high signal intensity lesions on T2-weighted imaging (T2WI), which is a typical MRI feature of clear cell renal cell carcinoma (RCC) that constitutes more than 60% of solid renal tumors [].However, some renal tumors can show low signal intensities on T2WI, and they are more likely to be considered as papillary RCC or fat-poor angiomyolipoma (AML) [1-6]. can someone explain what this means? Kidney tissue can become abnormal for a variety of reasons. Smaller masses are more likely to be benign.
