A Comparative Diagnostic Ability Between Ultrasound and Computed Tomography in Evaluation of Focal Liver Lesions
Keywords:Focal liver lesions, metastasis, hydatid cyst, ultrasound, CECT
Background: The term focal liver lesion refers to circumscript and well-defined liver tumours, which can either be benign or malignant. These lesions can be benign or malignant. Benign lesions include haemangioma, the most common benign tumour of liver.Objectives;1. To study the distributions of various focal liver lesions by ULTRASOUND and CECT. 2. To compare the findings of ULTRASOUND and CECT in focal liver lesions. 3. To assess the sensitivity and specificity of ULTRASOUND and CECT in various pathologies. 4. To assess which modality is more accurate in a particular pathology.Methods: Hospital based observational study was done in 65 patients having focal liver lesions. Clinically suspected, history or physical examination suggestive of a focal liver lesion which is confirmed by ULTRASOUND/CT at Maharajah Institute of Medical Sciences Vizainagaram, Andhra pradesh. Imaging Centre over a period of one year. SPSS was used for analysis.Results: It was seen the lesions were male preponderance (54%) and the most common age group was 61-70 years in both the sex followed by 31-40 years. the most common lesion was metastasis seen in 36% of cases followed by Cysts in 18% of cases. Sensitivity of USG was almost 100% except in Hemangioma (88.8%). Sensitivity and Specificity of CECT was 100% in all lesions.Conclusion:The sensitivity of USG in detecting liver metastases is comparable to CECT. CT is superior to USG in showing exact extent of a focal lesion and in delineating adjacent organs. Hence CT is useful to determine the extent of the liver tumors or hydatid cysts prior to surgical resection.
