Background Volumetric analysis is a novel radiological technique used in the measurement of target lesions in three dimensions in order to estimate the lesion’s volume. Recently, it has been used for evaluation of the remaining liver volume after partial hepatectomy and also for evaluation of the response of tumours to treatment. It has been proven to be more accurate than the standard one or two-dimensional measurements, and it is especially useful for the evaluation of complex tumours after radiological interventional methods when the use of standard methods is limited. In the current study, our aim was to evaluate the value of the three-dimensional (3D) volumetric method “Response Evaluation Criteria in Solid Tumours (vRECIST)” and to compare it with the non–three-dimensional methods (RECIST) and modified RECIST (mRECIST) in the assessment of the therapeutic response of hepatocellular carcinoma (HCC) after transarterial chemoembolization (TACE). Results A retrospective study was conducted on 50 patients with confirmed radiological or pathological diagnosis of hepatocellular carcinoma (HCC) who underwent TACE as the only interventional procedure and follwed up by triphasic CT 1 and 4 months after treatment. The study revealed a significant difference between mRECIST and vRECIST in the assessment of the therapeutic response of HCC after TACE, a weak agreement was found between both methods in the detection of complete response (CR), partial response (PR), stable disease (SD) or progressive disease (PD). Also, there was no significant agreement between mRECIST and vRECIST regarding the assessment by classifying the patients into responders or nonresponders. Conclusion Volumetric analysis is an effective method for measuring the HCC lesions and evaluating its response to locoregional treatment with a significant difference between vRECIST and mRECIST in the assessment of therapeutic response, which in turn help the interventional radiologist to decide the future treatments and change the therapeutic plans. Based on these results, we recommend vRECIST to be an essential part of the assessment of therapeutic response after locoregional therapy.

Purpose: We aimed to apply Ultrasound Liver Imaging Reporting and Data System (US LI-RADS) to the patients with positive serological HCV test surveyed during the national mass screening campaign. Methods: We conducted a cross-sectional study that recruited patients with positive serological test for HCV, who underwent the national mass screening campaign during the period from April 2019 to June 2020. Each operator was required to classify the patients into one of the following three categories according to the US visualization into: A, no or minimal limitations; (2) B, moderate limitations; and (3) C, severe limitations. Results: A total of 763 HCV patients were recruited in the present study. Conclusion: US is the modality of choice during mass screening for HCC, yet the presence of the human factor (being operator dependent) and the lack of unified reporting scheme were drawbacks; thus US- LI-RADS, overcome the latter drawback with ready to go plan according to the given score of each individual patient.
