AN ALGORITHM-BASED APPROACH TO THE SONOGRAPHIC DIAGNOSIS OF FOCAL LIVER LESIONS: A DVD-ROM TEACHING FILE WITH US IMAGE AND VIDEO DATABASE

Purpose: To teach the user to identify the principal sonographic features of a focal liver lesion To facilitate an accurate diagnostis by means of a simple algorithm employing sonographic characteristics To enable the comparison of the user's own US images to database images. Methods and Materials: The User can start using this teaching file by describing the US characteristics of a focal liver Lesion that he has difficulty in characterizing (Unilocular, hypoechoic, hypovascular). The system guides him through a specific algorithm of all possible liver lesions which fit the criteria. A large collection of US ima…
