肝脏内单发肿瘤样病变包括良性病变和恶性病变,常见的良性病变有肝炎性假瘤,局灶结节性增生,肝血管瘤,结节性肝硬化等,恶性病变主要是指原发性肝癌和继发性肝癌。螺旋CT增强扫描对正确诊断肝脏疾病有很重要的价值,应用中以双期扫描为主,三期扫描较少,加做延迟扫描的就更少了。现在普遍认为,延迟扫描对肝脏疾病的诊断是十分重要的,而且是必要的。现将延迟扫描技术,常见肝脏单发肿瘤样病变延迟扫描特征及相关的病理学基础综述如下。
Single tumor lesions in the liver, including benign lesions and malignant lesions, common benign lesions are hepatic pseudotumor, focal nodular hyperplasia, hepatic hemangioma, nodular cirrhosis, etc., mainly refers to the primary malignant lesions Liver cancer and secondary liver cancer. Spiral CT enhanced scan for the correct diagnosis of liver disease has a very important value, the application of double-phase scan-based, three fewer scans, plus delay scanning less. Now generally agreed that delayed scanning of liver disease diagnosis is very important and necessary. Now delayed scanning technology, common liver single tumor-like lesions delayed scanning characteristics and related pathology based on the following.
