Clinical and Contrast-enhanced Ultrasound Characteristics of Epithelioid and Classic Hepatic Angiomyolipoma: Comparison With Alpha-fetoprotein–negative Hepatocellular Carcinoma

December 19 , 2020 — Ultrasound in Medicine and Biology Abstract Hepatic angiomyolipoma (HAML) comprises epithelioid angiomyolipoma (EAML) and classic hepatic angiomyolipoma (CAML). The imaging appearance of HAML varies widely, and EAML is more easily misdiagnosed as hepatocellular carcinoma (HCC) than as CAML. The clinical and contrast-enhanced ultrasound (CEUS) features of CAML, EAML and HCC […]

Microbubbles Create Greater Radiation Sensitivity in Liver Tumors

December 15, 2020 — Diagnostic Imaging By Whitney J.
