Purpose: To report initial clinical experience with a new previously unreported vacuum-assisted device (EnCor MR, SenoRx, Aliso Viejo, CA) for magnetic resonance imaging (MRI)-guided breast biopsy and to compare this device with previously reported technologies. Materials and Methods:A prospective study of MRIguided vacuum-assisted breast biopsies using the EnCor device was undertaken. Lesions targeted for biopsy were occult on mammography, ultrasound, and physical examination. Histologic results were obtained for all cases. Patients with benign, concordant results underwent clinical and imaging follow-up. Cases with discordant, high-risk, or malignant results were referred for surgical biopsy.Results: A total of 55 biopsies were performed in 47 patients. All biopsies were technically successful. Histologic results yielded malignancy in 10 (10/55, 18%) of the 55 lesions and high-risk or atypical lesions in 7 (7/55, 13%) of the cases. All of these patients have had surgical follow-up, with four (4/55, 7%) underestimations. There were three (3/55, 5%) discordant cases. 35 (35/55, 64%) lesions yielded benign concordant results. Of these, six (6/35, 17%) lesions were removed surgically, with confirmation of the MR-guided biopsy results. Twenty (20/35, 57%) lesions have undergone at least 6-month follow-up MRI, with resolution or stability of the MRI findings. Conclusion:The EnCor breast biopsy device has comparable results to those previously reported for other MRIguided vacuum-assisted technologies.

“…If BI-RADS ® 4 or 5 findings detected on diagnostic MRI are no longer visible, it is necessary to first rule out technical causes. For example, strong breast compression may result in reduced contrast enhancement [25,27,30,31]. If there is reasonable suspicion that this is the case, a new MRI with reduced breast compression would be recommended.…”

Breast MR imaging has become established as?the most sensitive imaging method for diagnosing breast cancer. As a result of the increasing examination volume and improved image quality, the number of breast lesions detected only on MRI and requiring further clarification has risen in recent years. According to the S3-guideline ?Diagnosis, Therapy, and Follow-Up of Breast Cancer? as revised in July 2012, institutions performing breast MRI should provide the option of an MRI-guided intervention for clarification. This review describes the indications, methods and results of MRI-guided interventions for the clarification of breast lesions only visible on MRI. Recent guidelines and study results are also addressed and alternative methods and pitfalls are presented. Key points: Citation Format:

“…In the current study, MRI detected benign lesions that were occult at conventional imaging in 13% of the patients. These lesions are currently managed by correlative ultrasonography with ultrasound-guided biopsy [53], MRI-guided biopsy with dedicated biopsy coils [54][55][56][57][58][59][60][61], or a combination of radiological reading and reading by a computer [39]. We emphasize that a change of treatment in the current study was only performed after obtaining histopathological proof of the additional lesion.…”

Contrast-enhanced MRI in breast cancer patients eligible for breast-conserving therapy: complementary value for subgroups of patients

et al. 2005

The aim of this study was to identify patients prior to breast-conserving therapy (BCT) who have complementary value of contrast-enhanced magnetic resonance imaging (MRI) over conventional imaging in the assessment of tumor extent. All patients were eligible for BCT according to conventional imaging, and underwent preoperative MRI as part of this study. One hundred and sixty-five patients (166 tumors) were included. MRI was defined to have complementary value if conventional imaging underestimated or overestimated tumor extent (by more than 10 mm compared to histology) and MRI assessed the extent accurately. Logistic regression was employed to identify characteristics that are predictive of the complementary value of preoperative MRI. MRI had complementary value in 39 cases (23%). Patients <58 years old with irregular lesion margins at mammography and discrepancy in tumor extent by more than 10 mm between mammography and ultrasonography had a 3.2x higher chance of accurate assessment at MRI (positive predictive value 50%, negative predictive value 84%, p=0.0002). Preoperative MRI in patients eligible for BCT is more accurate than conventional imaging in the assessment of tumor extent in approximately one out of four patients. Subgroups of patients in whom MRI has complementary value may be defined by the differences in clinical and imaging features.
