Radiologic records of 121 lesions of 117 women, who had been referred for MRI-guided 10 G VABB for their MRI positive and second-look US negative lesions between 2013 and 2016, were retrospectively evaluated.
Finally, MRI compatible 10 G vacuum needle (Encor, Bard Biopsy Systems) was inserted instead of the obturator and VABB was performed.
Underestimation rate of MRI-guided VABB for high-risk patients was 21.4% (3/14).
This lesion was detected as a 4 mm focus in previous examination and diagnosed as fibrocystic changes at VABB. After surgical excision, the final diagnosis was invasive ductal cancer.
Mass lesions have the highest cancer detection rates with MRI-guided VABB in the literature.
Surgical excision is mandatory for high-risk lesions found at MRI-guided VABB, similar to other imaging-guided biopsy procedures.
Complications from MRI-guided VABB may include bleeding or pain during the procedure, postbiopsy pain, bleeding, and hematomas (4, 5).
MRI-guided VABB is a reliable diagnostic tool with a 11% false-negative rate.
In conclusion, MRI-guided VABB is a safe and successful procedure for the evaluation of MRI-only breast lesions.
