“…If standard control mammography (two orthogonal planes, cranio-caudal and medio-lateral oblique views) is done after stereotactic vacuum biopsy with clip marking [9], the question arises whether it is possible to detect dislocation of an intramammary marker clip after ultrasound-guided core needle biopsy with clip placement. Based on our previous experience [11][12][13][14] with intramammary clip marking systems, the aim of our current study was to investigate the accuracy of sonography and digital breast tomosynthesis to determine the location of intramammary marker clips placed in small breast cancers with diameters of less than 2 cm (cT1).…”

Around 55 000 women develop breast cancer and 20 000 women die of it in Germany every year [1]. The individual prognosis of patients with breast cancer depends in the first instance on the extent of disease at the time of diagnosis and on the implemented treatment plan [2][3][4]. According to both European treatment recommendations and the German interdisciplinary S3 Guideline for the Diagnosis, Treatment and Follow-up of Breast Cancer, at least 70 % of all breast Abstract ! Introduction: This study aimed to compare the accuracy of sonography versus digital breast tomosynthesis to locate intramammary marker clips placed under ultrasound guidance. Patients and Methods: Fifty patients with suspicion of breast cancer (lesion diameter less than 2 cm [cT1]) had ultrasound-guided core needle biopsy with placement of a marker clip in the center of the tumor. Intramammary marker clips were subsequently located with both sonography and digital breast tomosynthesis. Results: Sonography detected no dislocation of intrammammary marker clips in 42 of 50 patients (84 %); dislocation was reported in 8 patients (16 %) with a maximum dislocation of 7 mm along the x-, y-or z-axis. Digital breast tomosynthesis showed accurate placement without dislocation of the intramammary marker clip in 48 patients (96 %); 2 patients (4 %) had a maximum clip dislocation of 3 mm along the x-, y-or z-axis (p < 0.05). Conclusion: The use of digital breast tomosynthesis could improve the accuracy when locating intramammary marker clips compared to sonography and could, in future, be used to complement or even completely replace sonography.

“…Although DBT is now widely used in screening and diagnostic imaging, it is not routinely used for specimen imaging. Some studies have shown increased sensitivity with single view DBT specimen imaging and improved performance of DBT in lesion size assessment [14,26]. Chagpar et al also found that intraoperative DBT of the specimen led to a slight reduction in re-excision rate [27].…”

Lumpectomy Specimen Radiography: Does Orientation or 3-Dimensional Tomosynthesis Improve Margin Assessment?

Purpose Our purpose was twofold. First, we sought to determine whether 2 orthogonal oriented views of excised breast cancer specimens could improve surgical margin assessment compared to a single unoriented view. Second, we sought to determine whether 3D tomosynthesis could improve surgical margin assessment compared to 2D mammography alone. Materials and Methods Forty-one consecutive specimens were prospectively imaged using 4 protocols: single view unoriented 2D image acquired on a specimen unit (1VSU), 2 orthogonal oriented 2D images acquired on the specimen unit (2VSU), 2 orthogonal oriented 2D images acquired on a mammogram unit (2V2DMU), and 2 orthogonal oriented 3D images acquired on the mammogram unit (2V3DMU). Three breast imagers randomly assessed surgical margin of the 41 specimens with each protocol. Surgical margin per histopathology was considered the gold standard. Results The average area under the curve (AUC) was 0.60 for 1VSU, 0.66 for 2VSU, 0.68 for 2V2DMU, and 0.60 for 2V3DMU. Comparing AUCs for 2VSU vs 1VSU by reader showed improved diagnostic accuracy using 2VSU; however, this difference was only statistically significant for reader 3 (0.73 vs 0.63, P = .0455). Comparing AUCs for 2V3DMU vs 2V2DMU by reader showed mixed results, with reader 1 demonstrating increased accuracy (0.72 vs 0.68, P = .5984), while readers 2 and 3 demonstrated decreased accuracy (0.50 vs 0.62, P = .1089 and 0.58 vs 0.75, P = .0269). Conclusions 2VSU showed improved accuracy in surgical margin prediction compared to 1VSU, although this was not statistically significant for all readers. 3D tomosynthesis did not improve surgical margin assessment.

“…In diesen Fällen kann die Tomosynthese, eine 3D-Mammografie, hilfreich sein (▶ Abb. 4) [11]. Durch eine im 15-Grad-Winkel schwenkende Röntgenröhre entstehen Schichtaufnahmen in verschiedenen Projektionen, die eine 3D-Darstellung der Brust ermöglichen.…”
