Diagnostic Value on Mammary Gland Focal Benign and Malignant with MRI Digital Subtraction / 医疗卫生装备

ABSTRACT

Objective To study the diagnostic value on mammary gland focal benign and malignant with MRI digital sub- traction. Methods By analyzing 109 histopathology cases of breast neoplasm which can be use three dimensional dynamic contrast and MRI digital subtraction. Based on early-phase enhancement rate peak time, time-signal intensity curve and enhanced lesions way, the diagnostic value on it was evaluated. Results The specificity signs of breast carcinoma are en- hanced ways on MRI enhancement scanning. The filling type is contrast agent filled from edge to centre. The sensitivity is 82.9%; specificity is 79.0%; accurate rate is 80.7%. Conclusion The aggrandizement form on filling type of breast MRI digital subtraction scanning focus has obvious advantages in breast carcinoma diagnosis.
