肝扫描技术在鉴别右上腹部肿瘤取得了良好效果。但是,对于肝外肿瘤来说,仅限于其对肝脏未产生压迫的情况下。肝外肿瘤一旦压迫肝脏,使肝脏发生明显变形,肝扫描图就将产生明显变异,出现“缺损”图象,此时颇难与肝内占位性病变相区别。我们曾有过这方面 Liver scanning technology in the identification of right upper abdominal cancer achieved good results. However, for extrahepatic tumors, it is limited to the absence of pressure on the liver. Once the extrahepatic tumor is pressed against the liver, the liver undergoes obvious deformation and the liver scan will have obvious variation. The “defect” image appears, which is quite difficult to distinguish from the space-occupying lesion in the liver. We have had this before
