|April 1, 1985
Summary
Digital subtraction angiography (DSA) shows promise in differentiating benign from malignant breast lesions. This less invasive imaging technique could potentially reduce the need for surgical biopsies in breast cancer screening.
Area of Science:
- Medical Imaging
- Radiology
- Oncology
Background:
- Distinguishing benign from malignant breast lesions typically requires invasive and expensive surgical biopsies.
- Digital subtraction angiography (DSA) offers a less invasive alternative for breast lesion evaluation.
Purpose of the Study:
- To evaluate the potential of DSA in differentiating malignant from benign breast lesions.
- To compare DSA imaging patterns with surgical biopsy results.
Main Methods:
- DSA imaging was performed on 22 patients with known malignant or benign breast lesions.
- Low kilovoltage (50 kVp) imaging and superior vena cava contrast injection were utilized.
- The average breast radiation dose was maintained below 0.02 Gy.
Main Results:
- DSA imaging patterns showed potential for differentiating benign and malignant breast lesions.
- Preliminary results indicate DSA's capability in lesion characterization.
Conclusions:
- DSA demonstrates potential as a less invasive tool for breast cancer screening.
- Further research is warranted to establish DSA as a viable alternative to surgical biopsy.
