The Application of Elasticity Imaging on the Diagnosis of Prostate Cancer

Ultrasonic elastography is a new method of ultrasonic imaging which distinguish the stiffness of different tissue by analyzing different mechanical index. It was mainly used in the division and determination of nodules on breast or thyroid in the early stage. With the progress of science and technology and the improvement of medical lever, currently elasticity imaging is available for qualitative diagnosis and quantitative analysis on the interested region on the basis of two-dimensional ultrasonographic and has been applied to medical research and clinical diagnosis. The principle and the application of elasticity imaging, the developing trend and the diagnostic methods of prostate cancer and the value of elasticity imaging on the detection of nodules on prostate were introduced in this paper. Elasticity imaging is noninvasive, economic, convenient, dynamic real-time observing and repeatable, combined with other examinations, which can help early diagnosis, reduce stitches of prostate biopsy, and increase the detection rate of prostate cancer effectively.
