Dynamic magnetic resonance (MR) imaging with SmartPrep was compared with dynamic enhanced helical computed tomography (CT) for the detection of hepatocellular carcinoma (HCC). Thirty patients with 49 HCCs were studied. Arterial-phase MR images using with SmartPrep were significantly superior to arterial-phase CT in detecting small lesions (< or = 2 cm) (85.3% vs. 67.6%, P < .05). In addition, in six recurrent tumors after arterial chemoembolization, dynamic MR imaging with MR SmartPrep technique was superior to helical CT in detecting of recurrent tumors.
将采用SmartPrep的动态磁共振（MR）成像与动态增强螺旋计算机断层扫描（CT）用于检测肝细胞癌（HCC）进行比较。对30例患有49个HCC的患者进行了研究。采用SmartPrep的动脉期MR图像在检测小病灶（≤2 cm）方面明显优于动脉期CT（85.3%对67.6%，P<.05）。此外，在6例动脉化疗栓塞后的复发性肿瘤中，采用MR SmartPrep技术的动态MR成像在检测复发性肿瘤方面优于螺旋CT。
