肾脏原发性肿瘤种类繁多,多为恶性,且各病理亚型的影像表现均有不同。部分良性肿瘤如乏脂性血管平滑肌脂肪瘤、嗜酸细胞瘤难以与其区分,因此术前明确其组织学类型有助于治疗方案制定以及预后评估。CT是检查肾脏肿瘤的重要影像方法之一,除常规平扫、动态增强检查外,CT灌注成像、能量CT及PET-CT等亦提供了诸多信息。本文就其CT成像现状综述如下。 Kidney primary tumors of a wide range, mostly malignant, and the pathological subtypes of the imaging performance are different. Some benign tumors such as lipoangiatic angiomyolipoma, eosinophilic difficult to distinguish with them, so clear histological type preoperative help in the development of treatment options and prognosis. CT is one of the important imaging methods for detecting renal tumors. CT perfusion imaging, energy CT and PET-CT also provide a lot of information besides conventional plain scan and dynamic contrast enhancement. This article on its CT imaging status are summarized below.
