83例乳腺肿瘤超声和X线诊断分析

Ultrasound and Mammography in the Diagnosis of Breast Tumors:An Analysis of 83 Cases

本文分析了８３例乳腺肿瘤的超声诊断。肿物的灰阶超声表现有三种，良性型、恶性型和中间型。灰阶超声对良性型和恶性型肿物较易定性诊断，对中间型不易定性。２４例良性肿瘤彩色多普勒血流信号主要表现为Ⅰ型（８例）和Ⅲ型（６例），即呈单条血管供血，５例未见血流信号；８１％（４８／５９）的恶性肿瘤彩色多普勒血流信号为Ⅳ型，即有２条以上的供应血管向肿物集聚。结合肿物的灰阶超声特点和彩色多普勒表现有助于判断其良恶性，诊断符合率达９７．６％。对乳腺Ｘ线摄影的局限性和合理应用进行了讨论。

Ultrasound diagnoses of 83 breast tumors were analyzed.The echographic appearance of the tumors were classified into 3 categories:benign,malignant and intermediate type.Echography is easy in diagnosing the benign type masses and malignant type masses.But it's difficult to determine the benignity or malignancy of intermediate masses.Color doppler blood flow signals of 24 benign breast tumors are mainly manifested as type Ⅰ(8 cases) and type Ⅲ(6 cases),that is,only one vessel feeding the tumor.5 cases of benign breast tumors didn't show flow signal.81%(48/59) of malignant tumors showed type Ⅳ of flow signals,that is,more than two feeding vessels concentrating towards the mass like corkscrews,The combination of echographic appearance and color doppler manifestations gave a more accurate result with an accuracy of 97.6%.The limitations and appropriate application of mammography were also discussed.
