Non-contrast imaging characteristics of papillary renal cell carcinoma: implications for diagnosis and subtyping.

CONCLUSION: pRCCs may exhibit very low attenuation on pre-contrast CT. This appears more common among the more aggressive type-2 subtype. These data suggest that low attenuation (< 20 HU) alone on non-contrast CT imaging is insufficient as a single parameter to rule out malignancy. PMID: 31629440 [PubMed - in process]
