Interventional Study.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.

What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT05812040). This is a study registration, not published results. Lead sponsor: Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University. Recruitment status: COMPLETED. Phase: NA. Study type: INTERVENTIONAL. Enrollment: 134 participants (ACTUAL). Conditions: Breast Neoplasms, Nipple Discharge. Interventions: DIAGNOSTIC_TEST: Magnetic Resonance Ductography (MRD); and High-Resolution Magnetic Resonance Ductography (HR-MRD). Primary outcome measures: Analyze the sensitivity and specificity of HR-MRD in detecting lesions that require surgical excision in patients with PND , 15 months. Brief summary: Nipple discharge is one of the common symptoms of breast disease patients. Nipple discharge can be divided into physiological and pathological nipple discharge (PND). Among patients with PND symptoms who undergo biopsy, 5%-21% of them are malignant, and the risk of malignancy increases with age. The primary diagnostic imaging methods for PND patients include mammography and breast ultrasound. Nearly half of PND patients who undergo traditional mammography and ultrasound examination have negative findings, but this does not rule out the presence of malignant lesions. Central duct excision is the gold standard for PND diagnosis, but invasive surgery without imaging guidance can lead to some complications. Magnetic Resonance Ductography (MRD), which uses water imaging technology to visualize the inside of the duct without contrast injection, can show imaging features of ductal lesions such as filling defects, irregularities of duct walls, and ductal obstruction. However, previous studies have shown that the signal-to-noise ratio of MRD images needs to be improved. Microscopy coil has the characteristics of small voxels and high spatial resolution, making it suitable for high signal-to-noise ratio imaging of small superficial structures. This provides a hardware foundation for improving the quality of MRD images. Therefore, in this study, the investigators aim to use the 3T MR instrument and microscopy coil to perform non-invasive high-resolution Magnetic Resonance Ductography (HR-MRD) on PND patients to evaluate the ability of HR-MRD to detect PND causes and the imaging features of duct-related lesions on HR-MRD, to assist in the accurate diagnosis and treatment of PND.
