Preoperative Assessment of Pathological Nipple Discharge With Delayed Ductal Imaging of Contrast-enhanced Mammography
Preoperative Assessment of Pathological Nipple Discharge With Delayed Ductal Imaging of Contrast-enhanced Spectral Mammography: an Exploratory Study
The goal of the prospective, interventional, self-control, open, single-center clinical study: is to evaluate the value of the delayed ductal imaging of contrast enhanced Spectral Mammography acquired in 4-6 hours after the routine iopromide 370 mgI/ml-enhanced ductography for the clinical diagnosis of patients with suspected pathologic nipple discharge.
The main questions aim to answer are:
- Percentage of changes from baseline in imaging diagnosis caused by the results of delayed imaging.
- The rate of reported examination-related adverse events occurred within 7 days of the delayed ductal imaging.
- The average gland dose (AGD) of delayed ductal imaging.
After enrollment, subjects underwent CESM again within 4-6 hours post completing previous routine ductography to obtain a late-phase ductal image, which contains a low-energy image and a subtracted image obtained from the post processing.

Participation Criteria
Eligibility Criteria
Ages Eligible for Study
- Adult
- Older Adult
Accepts Healthy Volunteers
Description
Inclusion Criteria:
- Females aged 18-65 years old
- Completed routine iopromide 370 mgI/ml enhanced ductography for initial clinical diagnosis of suspected pathological nipple discharge, under the recommendation of the clinician
- Signed informed consent form for this study (signature and date)
- Committed to complying with study procedures and cooperating with the conducting of the full study process
- For women of childbearing age, should have taken contraceptive measures for at least one month prior to screening and must have a negative serum or urine pregnancy test, meanwhile committed to take contraceptive measures during the entire study and continue until a specified time after the end of the study
Exclusion Criteria:
- Pregnant or lactating women
- Experienced any episode of adverse events or discomfort after ductography with iopromide 370 mgI/ml
- Had any history of breast surgery, such as having undergone any invasive examination or surgical treatment due to the studied disease, including but not limited to breast duct micro-endoscopy, puncture biopsy, surgery, etc
- The ductal discharge symptom is more likely caused by other diagnosed/highly suspected diseases rather than a breast lesion, such as pituitary adenomas
- Other conditions are inappropriate for participation in this study judged by the investigator, such as the patient had difficulty to cooperate with ductography procedure, for example, loss of consciousness, communication impairment or nipple anomalies, and overly slender ducts
