肝脏的结节性病变中,良性结节性病变的发病率明显高于恶性病变,包括肝囊肿、肝海绵状血管瘤、局灶性结节增生、肝腺瘤以及炎症性病变等。近年来,随着医学影像学技术的进展,多层螺旋CT、磁共振成像、超声、正电子发射型计算机断层显像(PET-CT)等技术的广泛应用,为肝脏的病变的准确和特异性诊断提供了支持,部分病变可以从分子水平上评估其情况,有利于对病变进行治疗前的准确诊断。因此,认识肝脏各种良性占位性病变的影像诊断方法及其影像学表现,对临床诊治至关重要。
Among the nodular lesions of the liver, the incidence of benign nodular lesions is significantly higher than that of malignant lesions, including hepatic cysts, cavernous hemangiomas, focal nodular hyperplasia, hepatic adenomas, and inflammatory lesions. In recent years, with the progress of medical imaging technology, multi-slice spiral CT, magnetic resonance imaging, ultrasound, positron emission tomography (PET-CT) and other technologies widely used for the liver lesions accurate and specific Sexual diagnosis provides support, some lesions can be evaluated at the molecular level of its situation, is conducive to accurate diagnosis of lesions before treatment. Therefore, the understanding of various benign lesions of the liver imaging diagnostic imaging method and its performance is crucial for clinical diagnosis and treatment.
