Due to different etiologies, diagnosis and treatment of HCC in China is different from that in Western countries.US is an important screening method for HCC in patients with liver cirrhosis. CEUS, as an enhanced imaging method based on US, has the advantages of convenience, non-radiation, low cost, short examination time, and the diagnostic performance of HCC is comparable to that of CECT, CEMRI, and hepatobiliary-specific MRI.
It is of great significance to consider the cost-effectiveness of each examination based on the principle of cost minimization. Therefore, we propose immediate CEUS examination for suspicious lesions ≤2 cm screened by US, and determine the diagnostic process of further diagnostic methods based on the CEUS results. The aim of this study is to establish a screening and diagnosis process for HCC ≤2 cm suitable for China considering time effect, economic effect and diagnostic efficiency.

|---|---|---|---|
| Immediate CEUS group | Experimental | CEUS (SonoVue) was performed immediately after routine US screening of suspicious lesions. The lesions were classified according to CEUS examination by the diagnosing physician, including consideration of HCC, suspected HCC, and benign lesions. Further hepatobiliary-specific MRI (Modis/Primexian) was performed for lesions considered HCC or suspicious for HCC, and benign lesions were followed up. The diagnostic findings of hepatobiliary-specific MRI were classified by the diagnosing physician and included consideration of HCC, suspected HCC, and benign lesions. For hepatobiliary-specific MRI lesions considered HCC or suspicious for HCC, pathological examination was performed, and benign lesions were followed up. |
|
| Current clinical procedure group | No Intervention | After the suspicious lesions were screened by routine US, CECT, CEMRI and hepatobiliary-specific MRI (the first enhanced imaging examination) were independently selected by clinicians. According to the first examination results of the contrast-enhanced image, the diagnosis was classified by the diagnosing physician, including considering HCC, suspicious HCC, and benign lesions. Another contrast-enhanced imaging examination (CECT or CEMRI or hepatobiliary-specific MRI or CEUS) was performed again for lesions considered or suspected of HCC (second contrast-enhanced imaging study), and negative lesions were followed up. According to the examination results of the second enhanced imaging, the classification includes considering HCC, suspicious HCC, and benign. Pathological examination was performed for lesions considered HCC or suspicious for HCC on the second enhanced image, and benign lesions were followed up. |
