Abstract
HCC is the most common primary liver cancer with cirrhosis having strongest association. Ultrasound is the imaging modality of choice for screening of HCC. However, has lacked standardized guidelines for interpretation, reporting, and management recommendations.
The aim of this study was to test the application of US LIRADS algorithm in daily practice and analyse the outcomes of ultrasound categories, and visualization scores.
This study included 250 patients referred to the ultrasound unit of Radiodiagnosis and Intervention Department for screening. Patients were given an ultrasound category and visualization score.
According to ultrasound category; 88.4 % were given US-1 having negative ultrasound examination or benign observations, 1.2 % were given US-2 having subthreshold observations, and 10.4% were given US-3 having observations requiring further contrast enhanced modalities.
Patients of US-1 returned to normal surveillance. US-2 had short term follow up and proved benign. Patients of US-3 underwent contrast enhanced CT and accordingly; 57.6 % had HCC, 84.5 % had malignant lesions, and 11.5% had benign lesions.
According to the visualization score; 69.2 % given VIS-A with no limitations, 21.6% had VIS-B with moderate limitations and 9.2% given VIS-C with severe limitations. The most common reason for limited visualization among patients was gaseous distention.
The visualization score is a subjective assessment and affected by several factors either intrinsic or extrinsic, however it does not affect management plan. Identifying patients with inadequate examinations and those with inherent reasons of limited visualization, helps improve surveillance outcomes.
