0.05).The cytological false negative rate was 23.58% for LSIL,17.57% for high squamous intraepithelial lesion(HSIL),0.00% for squamous cell cancer(SCC),and 50.00% for adeno-carcinoma(AC);the false positive rate was 14.29% for LSIL and 3.85% for HSIL.Conclusion Liquid-based cytology test is an effective method for the screening of cervical cancer and precancerous lesion.The high-quality cervical cell specimen is important to ensure the diagnosis accuracy.

Differential Diagnosis of Breast Benign and Malignant Lesions with Three Dimensional Dynamic Contrast and Digital Subtraction MR Imaging / 实用放射学杂志

Objective To study the value of three dimensional dynamic contrast and digital subtraction MRI in diagnosing breast cancer.Methods 52 patients with breast diseases were enrolled in this study,including 27 malignant lesions and 36 benign lesions verified by histopathology.the morphologic features and enhancement kinetics of breast lesion on MRI were observed.The morphologic manifestation,early-phase enhancement rate,peak enhancement rate,peak time and time-signal intensity curve were evaluated.Results The benign lesions were mainly characterized by regular mass,well-defined border,internal septation,homogeneous enhancement,and the malignant lesions by irregular shape,speculated margin,rim enhancement,inhomogeneous enhancement.The early-phase enhancement rate,peak time and curve type were significantly different between breast benign and malignant lesions(P
