1 Arts n Sienes 3 Exmintion of three ses of pnreti lipoms y the ultrsonogrphy Key wors: pnreti lipom, ultrsonogrphy, CT, MR Summry Pnreti lipom is rre isese. We exmine four ses, epite y ominl ultrsonogrphy, in whih three ses were ignose s pnreti lipom in our hospitl. It ws ignose y plin CT imging, enhne CT imging t eh CT level, MR imging (FtSAT T2WI n T1WI in phse, oppose phse). In ition, I ompre the ultrsonogrphy of pnreti lipom to the CT imge. As result, ll the CT imges showe ft ensity, ut the rightness of the eho vrie. Our results were hypo eho level, iso eho level, hyper eho level, oringly. It ws onlue tht the efinitive ignosis of pnreti lipom with ultrsonogrphy is remins unler n iffiult. 43 CT CT CT MRFtSAT T2WIT1WI in phse oppose phse CT CT % Shinihi TAKEHARA 1, Hisnori ABE 1, Wtru SOUMA 1 1 ARITA GstoIntestinl Hospitl CT CT 130HU 30HUCT MRT2 FtSAT T m 60kg CT CT110HU 60HU Fig.1 CT Fig.1 CT110HU 55HUFig.1 CT120HU 55HU Fig.1CT120HU 55HU MR T2 Fig.2 FtSAT T2 Fig.2 T1WI in phse Fig
