Streaming detection, a novel ultrasound technique, shows promise in distinguishing breast cysts from solid masses. This method may reduce unnecessary cyst aspirations for indeterminate lesions.

Area of Science:

  • Medical Imaging
  • Diagnostic Ultrasound
  • Breast Imaging

Background:

  • Indeterminate breast lesions on sonography often require further investigation.
  • Differentiating cystic from solid breast masses is crucial for diagnosis and management.

Purpose of the Study:

  • To evaluate the utility of streaming detection for differentiating breast cysts from solid masses.
  • To assess the accuracy of streaming detection in indeterminate breast lesions.

Main Methods:

  • Streaming detection, a sonography technique using ultrasonic energy to detect fluid movement, was applied to 39 breast lesions.
  • Lesions were categorized as simple cysts, solid masses, or indeterminate.
  • Sensitivity, specificity, and predictive values were calculated; fluid viscosity, cyst size, and depth were analyzed.

Main Results:

  • Streaming detection demonstrated 82% sensitivity and 100% specificity for simple cysts and 100% specificity for solid masses in the control group.
  • In indeterminate lesions, streaming detection correctly identified 50% of cysts.
  • Neither cyst size, depth, nor fluid viscosity significantly impacted the technique's performance.

Conclusions:

  • Streaming detection shows potential in improving the differentiation of cysts from solid masses in indeterminate breast lesions.
  • This technique may reduce the need for invasive procedures like cyst aspiration.
