研究概览
简要总结
The purpose of this multicenter study is to evaluate the agreement among expert radiologists in interpreting magnetic resonance images (MRI) assessing common primary liver tumours in non-cirrhotic patients.
详细描述
Magnetic Resonance Imaging (MRI) is currently the method of choice for non-invasive diagnosis of primary liver tumors. However, differentiation of hepatocellular carcinoma (HCC) from adenoma and focal nodular hyperplasia (FNH) remains challenging, particularly in non-cirrhotic patients.

结局指标
主要结局
Inter-observer agreement among expert radiologists in diagnosing primary liver tumors by Magnetic Resonance Imaging (MRI).
时间窗: December 2010
Inter-observer agreement for categorical data will by assessed by the Fliess' kappa (good agreement \>0.7).
次要结局
- Agreement of radiologists with the actual diagnosis of primary liver tumors assessed by Magnetic Resonance Imaging (MRI).(December 2010)
- Differences in radiologist' certainty of diagnosis (CoD) among different tumor types.(December 2010)
- Intra-class correlation coefficient among radiologists' Certainty of Diagnosis (CoD) in diagnosis primary liver tumors by Magnetic Resonant Imaging (MRI)(December 2010)
- Investigate the diagnostic efficacy of radiologists' certainty of diagnosis (CoD) in accurately predicting primary liver tumors assessed by Magnetic Resonant Imaging (MRI)(December 2010)
