Condition: Liver Cancer · Sponsor: Second Affiliated Hospital, School of Medicine, Zhejiang University
Liver cancer (LC) is the sixth most common malignant tumor and the third cause of cancer mortality in the world. According to the 2018 United States Association for the Study of Liver Diseases guidelines for the diagnosis and treatment of liver cancer, patients with HCC high-risk factors can be directly diagnosed by imaging if they have typical imaging signs, without the need for puncture pathological confirmation. Since 2011, United States the American College of Radiology (ACR) has successively launched Liver Imaging And Reporting and Data System (LI-RADS) based-on contrast-enhanced CT (CECT), contrast-enhanced MRI (CEMRI), and contrast-enhanced ultrasound (CEUS) , which have achieved good clinical diagnostic results and are constantly being updated and improved.LI-RADS provides standardized imaging diagnosis for high-risk populations and classifies each liver lesion into LR-1 to LR-5 (possibility of HCC), LR-M (probably or definitely malignant, but not HCC), LR-TIV (intravenous tumor). Although CEUS LR-5 has a high accuracy in diagnosing HCC, there is also a considerable proportion of HCC in CEUS LR-4 and CEUS LR-3. Studies have shown that CEUS LR-M contains a high proportion of HCC, the sensitivity of CEUS LR-5 in diagnosing HCC is relatively low, and the possibility of HCC cannot be ruled out if it is not classified as CEUS LR-5. Therefore, how to improve the diagnostic sensitivity and specificity is the key goal of CEUS LI-RADS. According to the CEUS LI-RADS diagnost…
