Abstract :

Sonography plays a major role in the diagnostic workup of the liver. Present study was designed to compare the role of three techniques i.e. CUS, THI and PIHI. PIHI showed high sensitivity (98.08%), specificity (100%) and overall accuracy (99%) in conspicuity of visualization of solid lesions than both THI (94.23%, 100% and 97% respectively) and CUS (92.31%, 100% and 96% respectively).Both PIHI and THI were found to be of better than CUS in sensitivity, specificity and overall accuracy of visualization of cystic lesions. THI showed better sensitivity, specificity, overall accuracy in conspicuity of visualization than CUS in both solid and cystic lesions. PIHI (p<0.05) was found to be better than THI and CUS in lesion conspicuity, internal architecture, margins and overall image quality of solid lesions. PIHI (p<0.05) was also found to be better than THI and CUS on posterior enhancement, side lobe artifact and overall image quality of cystic lesions and showed no difference than THI in lesion conspicuity in cystic lesions
