This article describes that fine needle aspiration cytology(FNAC) under the ultrasonical guidance is performed in 144 patients with hepatic focal lesions.The positive rate of FNAC was 86.27%(88/102)in patients with hepatic cancer.Thefalse negative rate was 13.73%(14/102).The possible cause of false negative rate and themethod of increasing positive results were discussed.The FNAC is a simple,quick,harmless and inexpensive technique which will gain wide acceptance.

本文报道了144例肝局灶性病变在B 超引导下细针吸取细胞学(FNAC)检查的结果。对肝恶性病变的穿刺阳性率为86.27%(88/102),假阴性为13.73%(14/102)。并对假阴性的可能原因和提高穿刺的阳性率进行了讨论。FNAC 是一种简单、迅速、可靠、并发症少且所需费用低的检查技术,值得推广。

Purpose To evaluate dynamic contrast enhanced MR scanning in the diagnosis of focal liver lesions. Methods Focal liver lesions in 137 patients, including hepatocellular carcinoma (HCC), intrahepatic peripheral cholangiocarcinoma, metastasis, hemangioma and cyst, were prospectively studied. After SE T 1 weighted imaging and turbo SE T 2 weighted imaging at transverse section, dynamic scans with fast field echo sequence and central K space acquisition without breath hold were obtained...

Purpose To evaluate dynamic contrast enhanced MR scanning in the diagnosis of focal liver lesions. Methods Focal liver lesions in 137 patients, including hepatocellular carcinoma (HCC), intrahepatic peripheral cholangiocarcinoma, metastasis, hemangioma and cyst, were prospectively studied. After SE T 1 weighted imaging and turbo SE T 2 weighted imaging at transverse section, dynamic scans with fast field echo sequence and central K space acquisition without breath hold were obtained at seven contiguous sections with eight phases. Results Dynamic scans were obtained successfully in all patients. Time intensity curves at dynamic scans presented fast up and down in HCCs, slow up in intrahepatic peripheral cholangiocarcinomas, slow up with ring enhancement in metastasis, fast up and keeping high level in hemangiomas and no enhancement in hepatic cysts. Conclusion Central K space acquisition without breath hold could be used to do dynamic scan of the liver. Various hepatic focal lesions had different enhancement patterns on the dynamic scans.

目的探讨肝脏局灶性病变MR动态增强扫描方法及临床意义。方法作者前瞻性研究了136例肝脏局灶性病变,包括肝细胞性肝癌、周围型肝内胆管细胞性肝癌、转移瘤及海绵状血管瘤。采用平静呼吸状态下梯度回波K空间中心部分采集技术、7个连续层面8个时相动态增强扫描。结果各例均动态增强扫描成功。动态扫描显示时间信号强度曲线在肝细胞性肝癌呈速升速降型;胆管细胞癌呈渐升型;转移瘤呈环形强化,缓慢升高型;海绵状血管瘤呈速升平台型。结论平静呼吸下K空间中心部分采集肝脏动态扫描,可以显示肝脏局灶病变的血供状态,而且不同病变具有不同的强化特征。

Objective:To study method and clinical application of dynamic contrast-enhanced MR scanning in the diagnosis of focal liver lesions.Methods:Focal liver lesions 68 cases,including hepatocellular carcinoma(HCC),intrahepatic peripheral cholangiocarcinoma,metastasis,hemangioma and focal nodular hyperplasia,were studied.Breath-hold dynamic scans with FLASH 2D T1-weighted imaging were obtained.Results:Various hepatic focal lesions had different enhancement patterns on the dynamic...

Objective:To study method and clinical application of dynamic contrast-enhanced MR scanning in the diagnosis of focal liver lesions.Methods:Focal liver lesions 68 cases,including hepatocellular carcinoma(HCC),intrahepatic peripheral cholangiocarcinoma,metastasis,hemangioma and focal nodular hyperplasia,were studied.Breath-hold dynamic scans with FLASH 2D T1-weighted imaging were obtained.Results:Various hepatic focal lesions had different enhancement patterns on the dynamic scans:strong enhancement on arterial phase and slight enhancement on portal venous phase in HCCs;slower enhancement in intrahepatic peripheral cholangiocarcinomas;ring enhancement in metastasises;obvious and keeping long time enhancement in hemangiomas;strong enhancement on arterial phase and slight or obvious enhancement on portal venous phase and slightly delayed enhancement of the central scars in focal nodular hyperplasias.Conclusions:Dynamic Gd-DTPA contrast-enhanced imaging is a useful method in diagnosis of focal liver lesion.

目的 :探讨肝脏局灶性病变MR动态增强扫描的方法和临床应用。方法 :回顾性分析68例肝脏局灶性病变 :包括原发性肝细胞癌24例 ,周围型胆管细胞癌2例 ,转移瘤16例 ,海绵状血管瘤24例 ,局灶性结节增生2例。MR动态增强扫描采用一次屏气梯度回波序列 ,快速小角度激发二维(FLASH2D)准T1WI加权像。结果 :MR动态增强扫描显示肝内不同局灶性病变有不同的强化特征。原发性肝细胞癌动脉期明显强化 ,门脉期强化迅速减弱 ;周围型胆管细胞癌呈逐渐缓慢强化 ;转移瘤呈环型强化 ;海绵状血管瘤持续明显强化 ;局灶性结节增生动脉期明显强化 ,门脉期明显或轻度强化 ,延迟期中心疤痕轻度强化。结论 :MR动态增强扫描对肝脏局灶性病变的定性诊断是一种有价值的方法
