Diagonistic Value of ARFI in Breast Lesions

Abstract

Breast cancer became the most prominent cancer type in women worldwide. Its prevalence increased in recent years due to changes in life style and relapse among the patients seemed to be higher. Acoustic radiation force impulse (ARFI) imaging in based on the principle of the ultrasonic elasticity and the elestography accurately predict and measure the changes in breast cancer tissue compared to the normal tissue. It is a technical alternative to the palpation and able to measure lesser than 10 mm size. In contrast to biopsy, where the reduced deformability would occur and lead to biopsy failing. In fibroadenoma, due to its complications, many false positives could be detected and the ARFI elastography serve as an effective alternative method for breast cancer confirmation. The tissue stiffness index value is used to differentiate the benign and malignant tissue samples. ARFI further, use B- mode elasticity and help in recommending the biopsy confirmation.
