AbstractPurpose: Primary liver cancer ranks third among causes of cancer deaths worldwide. Lesser studies have been done for comparison of diagnostic performance of dynamic triple phase Computed Tomography (CT) and Contrast enhanced Magnetic Resonance Imaging (EOB-MRI) by using LI-RADS v2024. We compared the detection and outcome prediction abilities between dynamic CT and EOB-MRI for HCC as well as other hepatic lesions using LI-RADS v2024.
Methods: It was an Observational, Cross-sectional study carried out at Radiodiagnosis Department at a tertiary care hospital, Ahmedabad after the IRB approval, carried out over the period of July 2023 to June 2024 which included 60 patients with some form of focal liver lesions confirmed by Ultrasound. CT of liver was performed using 16 slice SIEMENS machine and MRI of the liver was performed on 1.5T SIEMENS machine.
Results: The predominant age group involved was the 5th decade with a male to female ratio of 3:1. In our study, the sensitivity and specificity for detection and grading of liver lesions was better for MRI than for triple phase CT in comparison with histopathological diagnosis (98% sensitivity and 95% specificity for EOB-MRI, 85% and 90% for CT Triple phase respectively). It was also seen that in calcified lesions, CT was better than MRI
Conclusion: In conclusion, multiphasic CT as well as contrast enhanced MRI play an important role in diagnosis and characterization of liver lesions, depending on the lesion type. Moreover, LIRADS grading of the lesions helps in determining the further line of treatment as well as assessment of treatment response.
