Fast MRI-guided vacuum-assisted breast biopsy: initial experience

Area of Science:

• Radiology
• Oncology
• Surgical Pathology

Background:

• Magnetic Resonance Imaging (MRI) is crucial for detecting breast lesions.
• Accurate tissue sampling is essential for diagnosis and treatment planning.
• Minimally invasive biopsy techniques are preferred when feasible.

Purpose of the Study:

• To evaluate a novel MRI-guided vacuum-assisted biopsy technique.
• To assess the accuracy of vacuum-assisted biopsy compared to surgical excision histology.
• To determine the safety and efficiency of this new biopsy method.

Main Methods:

• Prospective study of 20 women undergoing MRI-guided needle localization and surgical biopsy.
• MRI-guided vacuum-assisted biopsy performed using a vacuum-assisted probe.
• Placement of a localizing clip post-biopsy, followed by surgical excision.
• Correlation of vacuum-assisted biopsy results with surgical histology.

Main Results:

• Successful vacuum-assisted biopsy in 95% of cases (19/20 women).
• Cancer detected in 32% of women (6/19) and 30% of lesions (8/27).
• High concordance between vacuum-assisted biopsy and surgical histology.
• Median biopsy time of 35 minutes; successful clip placement in 96% of lesions.
• One complication (hematoma) resolved with compression.

Conclusions:

• MRI-guided vacuum-assisted biopsy is a rapid, safe, and accurate diagnostic tool.
• This method serves as a viable alternative to traditional surgical biopsy for MRI-detected breast lesions.
• The technique demonstrates high diagnostic yield and minimal complications.
