Malignancy mimic: Suspicious mammographic and sonographic findings post-vacuum-assisted excision biopsy.

Vacuum-assisted excision biopsy (VAEB) provides a safe alternative to surgical excision for selected (low-risk) B3 breast lesions. We report a case of imaging findings that mimicked malignancy in a patient one year post-VAEB. Awareness of this entity is important to prevent misdiagnosis and unnecessary surgical excision.

Radial scar appearances on contrast-enhanced mammography.

With modern technological advances in imaging, radial scars are more frequently encountered in clinical practice. The management of radial scars remains challenging due to associated upgrade to malignancy at excision. Contrast-enhanced mammography (CEM) has a similar sensitivity compared to MRI in addition to lower cost, better availability and fewer contra-indications.

Accuracy and precision of contrast enhanced mammography versus MRI for predicting breast cancer size: how "good" are they really?

Objective: To evaluate and compare the accuracy and precision of contrast-enhanced mammography (CEM) MRI to predict the size of biopsy-proven invasive breast cancer.

Methods: Prospective study, 59 women with invasive breast cancer on needle biopsy underwent CEM and breast MRI. Two breast radiologists read each patient's study, with access limited to one modality.

Does breast biopsy marker cost and availability influence utilisation in radiology practice?

Introduction: Breast Screen Australia and Breast Screen Aotearoa guidelines recommend breast biopsy marker (BBM) use in indicated patients. This study aims to evaluate whether BBM cost and availability impacts BBM utilisation.

Methods: An online survey was disseminated to radiologists who identified 'breast imaging' as their area of practice in the Royal Australian and New Zealand College of Radiologists (RANZCR) customer relationship management system.

Vacuum-assisted excision biopsy for definitive diagnosis of breast lesions of uncertain malignant potential (B3 lesions) on core biopsy - A single centre Western Australian experience.

Introduction: In Australia, the usual approach to breast lesions where core biopsy returns an uncertain result ("B3" breast lesion) is to perform surgical diagnostic open biopsy (DOB). This is associated with patient time off work, costs of hospital admission, risks of general anaesthesia and surgical complications. The majority of B3 lesions return benign results following surgery.

Evaluating breast biopsy practice and breast biopsy marker utilisation in the clinical setting.

Introduction: Breast Screen Australia and Breast Screen Aotearoa guidelines recommend breast biopsy marker (BBM) use in indicated patients. This study aims to evaluate breast biopsy practice and BBM utilisation by modality.

Methods: An online survey was disseminated to radiologists who identified 'breast imaging' as their area of practice in the Royal Australian and New Zealand College of Radiologists (RANZCR) customer relationship management system.

Pre-operative localization of impalpable breast lesions using iodine 125 seeds: Placement accuracy and multidisciplinary challenges.

Introduction: The number of impalpable breast lesions requiring pre-operative lesion localization (PLL) continues to increase. The use of Radio-guided Occult Lesion Localization with Iodine 125 Seeds (ROLLIS) offers multiple benefits for the multidisciplinary team (MDT), but is not without challenges.

Aims: The aims of this audit were to review our multidisciplinary team's experience following introduction of ROLLIS as standard of care for PLL, identify challenges and evaluate seed placement accuracy (SPA).

Are breast biopsy markers underused?

Introduction: To evaluate current use of breast biopsy markers (BBM) amongst Australian and New Zealand radiologists.

Methods: Radiologists attending a national breast conference were invited to complete an online survey addressing demographics, BBM use following ultrasound, stereotactic, tomosynthesis and MRI-guided biopsy, frequency of early BBM displacement, preoperative lesion localisation (PLL) and axillary BBM use.

Results: Overall response rate was 52% (60/115).

Radiographer technique: Does it contribute to the question of clip migration?

Introduction: Marker clips are commonly deployed at the site of a percutaneous breast biopsy. Studies have shown that displacement of the clip from the site of deployment is not uncommon. The objective of this study was to determine how much 'migration' could be seen with fixed structures within the breast tissue across three consecutive annual screening examinations, and therefore attempt to quantify how much of the reported clip migration could be due to radiographer technique.
