Area of Science:

  • Medical Imaging
  • Radiology
  • Diagnostic Techniques

Background:

  • Abnormal nipple discharge is a common clinical presentation.
  • Visualizing minute intraductal lesions is crucial for accurate diagnosis.
  • Helical CT was explored as a novel imaging modality.

Purpose of the Study:

  • To evaluate the utility of helical CT for visualizing intraductal lesions.
  • To assess the effectiveness of ductal CT imaging in patients with abnormal nipple discharge.

Main Methods:

  • Galactography followed by helical CT (ductal CT examination).
  • Ductal CT images were constructed using specialized software.
  • Diagnosis was based on comparison with known ductal fiberscopic findings.

Main Results:

  • Ductal CT examination was successful in 9 out of 10 cases.
  • Constructed ductoscopic images allowed observation of luminal surface structure.
  • Limitations included inability to assess color tone or hemorrhage.

Conclusions:

  • Ductal CT examination is a useful tool for intraductal observation in abnormal nipple discharge.
  • It enables visualization of the most minute intraductal lesions.
  • Further studies are needed to refine ductal CT imaging as a standard examination method.
