In our breast unit a significant proportion of core biopsies are performed freehand sometimes necessitating a repeat biopsy under image guidance. The aims of this study were to establish the proportion of patients undergoing freehand core biopsies who proceeded to a repeat procedure and to determine any factors associated with a missed freehand biopsy. Four hundred and ten core biopsies over 21 months were included in the analysis. Demographic details, position and size of the lump, breast volume and lesion depth were recorded.

Twenty-four percent freehand biopsies were repeated under ultrasound guidance. The histological classification of two-thirds of the repeat biopsies were upgraded, suggesting that the lesion had been previously missed. Multivariate analysis showed that missed freehand biopsies were strongly associated with deep lesions. If all lumps sited at a depth of 6 mm or more were selected for US-guided core biopsy, the workload for the ultrasound department would increase by just less than a half and would have the effect of reducing the freehand biopsy miss rate by almost two-thirds.

Core biopsies should be performed under ultrasound guidance. A freehand technique could be limited to superficial lesions. Depth is more predictive for a missed biopsy than lesion size or breast volume

This study aimed to establish the frequency of successful targeting of the SLN by ultrasound guided biopsy. False negative rate for CB of 30%. Reasons for false -ves - failure to sample the sentinel lymph node in 10 (45%) and failure to sample the metastatic disease in the sentinel node in 11 (55%). Better methods of identifying the sentinel lymph node and more adequate sampling are required

Purpose: to introduce and evaluate the usefulness of the combination of wire localization and ultrasound (US)-guided, vacuum-assisted breast biopsy (VAB) to histologically diagnose mammographically detected clustered microcalcifications in the absence of sonographic and clinically palpable masses. Appears to be an accurate and useful method for diagnosing mammographically detected, clustered microcalcifications

The aim of the paper was to evaluate the usefulness of contrast-enhanced ultrasound using the microvascular imaging technique in the diagnosis of breast lesions. Conventional and contrast-enhanced ultrasound using the microvascular imaging technique were performed after administration of SonoVue. The peripheral enhancement pattern was suggestive of malignancy, with a sensitivity of 39.5%, specificity of 98.3%, PPV of 94.4%, NPV of 69.4%, and accuracy of 73.8%. Homogeneous, regional, and heterogeneous enhancement patterns did not show meaningful diagnostic information

Ultrasound elastography using the extended combined auto-correlation method of tissue elasticity allows for real-time strain image visualisation using a free-hand probe with concurrent conventional B mode imaging. Four hundred and fifteen consecutive women with 550 breast lesions confirmed on B mode ultrasound were assessed with elastography using the elasticity score. There were 119 malignant and 431 benign lesions. The elastography sensitivity was 78.0%, specificity was 98.5% and overall accuracy was 93.8%. The median score for malignancy was 5 and that for benign lesions was 2.

There was good correlation with B mode BIRADS category. 98.6% of lesions with an elasticity score of 2 or below (95%CI=96.8–99.4) were benign. BIRADS 3 lesions with an elasticity score of 2 or below may be re-classified as BIRADS 2 lesions. We found that 15.3% of BIRADS 2 and 3 lesions with an elasticity score of 3 were malignant. Real-time ultrasound elastography is user-friendly with a high accuracy rate, thereby improving B mode ultrasound assessment.
