Tumor ablation
Time Frame: 1 month
|
Successful tumor ablation will be defined as absence of residual viable invasive or in situ carcinoma in the surgical specimen.

Measure Description |
Time Frame |
|---|---|---|
|
Negative predictive value of magnetic resonance imaging (MRI)
Time Frame: 14 days and 28 days
|
Magnetic resonance imaging will be conducted between 14 to 28 days after cryoablation.
Negative predictive value of MRI will be calculated according to the pathological report after the traditional surgery.
Negative predictive value = number of the patients who is pathologically negative divided by the number of patients who is MRI negative.
|
14 days and 28 days
|
|
Accuracy of conventional imaging methods (mammography and ultrasound)
Time Frame: 14 days and 28 days
|
Mammography and ultrasound will be conducted between 14 to 28 days after cryoablation.
Accuracy of conventional imaging methods will be calculated according to the pathological report after the traditional surgery.
|
14 days and 28 days
|
|
Measurement of the ice ball by ultrasound
Time Frame: 14 days and 28 days
|
To compare the baseline tumor size, ultrasound measurement of the ice ball, and the pathological result.
|
14 days and 28 days
