Summary
Real-time spatial compound imaging in breast ultrasound improves image quality by reducing speckle and enhancing lesion visualization. However, conventional imaging better preserves specific cyst and fibroadenoma features.
Area of Science:
- Medical Imaging
- Radiology
- Ultrasound Technology
Background:
- Breast ultrasound (US) is crucial for diagnosing benign breast changes.
- Conventional B-mode US can be limited by artefacts and image noise.
- Advanced imaging techniques aim to improve diagnostic accuracy.
Purpose of the Study:
- To evaluate the role and effectiveness of real-time spatial compound imaging in breast ultrasound.
- To compare image quality and lesion depiction between conventional B-mode US and spatial compound imaging.
Main Methods:
- 38 patients with 50 benign breast changes underwent both conventional B-mode US and real-time spatial compound imaging.
- Images were independently reviewed by three experienced breast US readers.
- Evaluation used a multistage scoring system assessing artefacts, boundaries, and internal structures.
Main Results:
- Real-time spatial compound imaging demonstrated significant speckle reduction and improved tissue differentiation.
- It enhanced conspicuity of low-contrast lesions, capsular margins, and ducts.
- Depiction of internal architecture in solid lesions and cystic contents improved, with reduced clutter.
- Conventional imaging showed better preservation of acoustic enhancement and edge shadowing in specific lesions.
Conclusions:
- Real-time spatial compound imaging offers substantial benefits for breast ultrasound image quality and lesion characterization.
- While generally superior, conventional imaging retains advantages for specific features in certain benign lesions.
