Objective:

To analyze the diagnostic value of conventional ultrasound and mammography in different types of breast masses.

Methods:

A retrospective analysis was performed on the data of 1 600 patients who underwent both conventional ultrasound and mammography examination in Shanghai General Hospital

Shanghai Jiao Tong University from January 2013 to August 2019. Pathological results we

re used as the gold standard to investigate the diagnostic value of conventional ultrasound and mammography in different types of breast masses.

Results:

There were 867 benign masses and 733 malignant ones. Four hundred and ninety-one were non-dense and 1 109 were dense. The sensitivity of conventional ultrasound was significantly higher than that of mammography

while the specificity of mammography was higher than that of conventional ultrasound. The difference was statistically significant (

P

＜0.05). For dense breasts and young patients (40 years)

the sensitivity of conventional ultrasound was significantly higher than that of mammography

and the specificity of mammography was significantly higher than that of conventional ultrasound (

P

＜0.05). For non-dense breasts and patients over 40 years old

the sensitivity of conventional ultrasound was higher than mammography and mammography was more specific

but there was no statistical significance (

P

＞0.05). The sensitivity of the combined diagnosis was higher than both of two single test methods

and the specificity was lower

whether in different ages or different types of breast

and the comparison was statistically significant (

P

＜0.001).

Conclusion:

The sensitivity of conventional ultrasound in dense breasts and young patients(40 years) is significantly higher than that of mammography

and the specificity of mammography is higher. The combined diagnosis is more sensitive to the diagnosis of breast masses than both of two single test methods

whether in different ages or different types of breast.
