Rationale and objectives : Several commercially available breast tissue markers are promoted as being sonographically visible, allowing for subsequent targeting using ultrasound. The aim of this study was to compare the visibility of selected sonographic markers with the use of tissue phantoms.

Six participants assessed their sonographic visibility and needle targeted the markers using ultrasound. The sonographic visibility of each marker was graded, with scores corrected for accuracy following mammographic review of needle targeting position. Conclusion : There is significant variance in the visibility of breast tissue markers purported to be visible on ultrasound.

The deployment of breast tissue markers is well established to enhance the subsequent visibility of clinical and radiological regions of interest. Markers are commonly deployed when a lesion undergoing percutaneous biopsy is natively inconspicuous, predicted to become so following neoadjuvant therapy, or where the biopsy process itself has significantly reduced the lesion's visibility or removed it entirely.

Clearly, reliable localisation must be a key quality of marker design, in addition to other requirements such as clinical safety, ease of deployment, cost and resistance to immediate or delayed migration. The purpose of this study was to assess and compare the sonographic visibility of several breast tissue markers, to evaluate their likely utility in future clinical situations. A secondary goal was to assess the relationship of marker detection to observer clinical experience.

Ethics approval for the study was not deemed necessary by the chairperson of the Institutional Ethics Committee. The authors do not have any conflicts of interest to declare, and no funding was received, although all markers utilised were provided by the respective vendors upon request. Seven breast tissue markers were evaluated Table 1 , Figure 1 , recognising that these were not an exhaustive representation of all commercially available products, and that all size and shape variants were not tested for logistical reasons.

For this phantom study we utilised fowl tissue, with prior studies suggesting it to be reasonably sonographically analogous to human breast tissue. Markers were deployed into eight similar sized skinless boneless chicken breasts and eight beef steaks with one phantom in each set designated as a control.

Markers were deployed under ultrasound guidance utilising the provided introduction devices, except for those with flexible or blunt tipped introducers where a coaxial technique was utilised. To prevent participants from deducing marker location by the entry site or needle tract, markers were placed with:.

Six radiologists participated in the study: two registrars in training with three months of prior breast imaging experience; two Fellows with an interest in breast imaging; and two specialised breast imaging consultant radiologists. The study was performed over two separate days, one week apart one registrar, one Fellow, one consultant each day , with the samples frozen in the intervening week.

The first three participants assessed the markers in both the chicken and beef samples, however there was a marked increase in echogenicity and shadowing in the beef phantoms following freezing and defrosting precluding further use. Participants were given one minute per sample to either localise the marker or to determine that no marker was present. If a marker was thought to be present, a sonographic image was obtained and participants then needle targeted the finding.

Participants were required to grade their ease in locating the finding according to Table 2a. If an incorrect localisation was readily attributable to another finding such as an air locule, this was recorded. The participants' grades of ease of localisation were then corrected by two different methods. For comparative assessment of the markers Table 2c , if an incorrect localisation occurred, the score was corrected to 0 as the marker was not seen, while correctly localised scores were preserved.

For comparative assessment of the participants Table 2d , if an incorrect localisation occurred, the score was inverted e. The primary method of analysis to contrast the different markers and to examine the influence of the participant level of experience, and composition and size of the markers was an ordinal logistic regression analysis with corrected accuracy as the dependent variable.

This method was chosen because the accuracy measure constitutes an ordinal scale of measurement. To overcome this problem the regression models were run with robust estimation of the standard error that accommodates the clustering of observations. Another assumption of the method is the proportional odds assumption, which assumes that the odds ratios are proportional to the ordered level of the outcome variable, accuracy.

Summated corrected scores for each marker are presented in Table 3. Robust standard errors were utilised to estimate P values, to correct for the multiple observations made by each observer within the data clustering.

Statistical evaluation by clustered ordinal logistic regression analysis demonstrated a statistically significant odds ratio of 1. The average scores of each of these groups Metal only Total corrected participant scores for consultants were 52, versus registrars 35 and fellows 27, without statistically significant differences between the groups elucidated in this study Table 6. Our study confirms the considerable variability in the sonographic visibility of various breast tissue markers, with statistically significant differences elucidated in our relatively small sample size.

While it is not possible to elucidate all of the contributing factors resulting in these variances in visibility, we isolated two factors: marker size and composition, which were thought to be contributory. While these findings imply that increased marker size equates to increased marker visibility, the same cannot necessarily be said in regard to accuracy of lesion localisation. Presumably a threshold is reached where an increase in size provides minimal additional visibility, but unnecessarily increases the size of the region marked, potentially confusing the precise lesion location especially for smaller lesions.

In a similar sense, the accuracy of lesion localisation may also be influenced by the ratio of the marker size to the biopsy cavity size particularly in vacuum assisted biopsies.

Marker shape also presumably influences visibility, however due to marked variability in this and the limited sample size, statistical assessment of this was not possible.

We recognise the following potential limitations and confounding factors with our study, and discuss methods utilised to abate their effect:. Inhomogeneity of samples: the presence of echogenic air locules in samples would presumably increase the potential for incorrect localisations. While markers were introduced under saline to prevent this, we nonetheless identified six instances where this occurred.

Variance in marker position: variability in marker placement position may create bias, however conformity to certain parameters of depth, location and angulation were undertaken to reduce this, though with enough variance to prevent predictability. Visibility of entry sites and tracts: the deduction of marker position by observation of needle entry sites or tracts could be a confounding factor, however minimised by introduction via the inverted surface, and creation of false tracts.

Sample size: we recognise the limited sample size, with each marker assessed in two samples chicken and beef , with each sample assessed by six observers. Greater numbers of both samples and observers would increase the number of trends reaching statistical significance.

Learning curve: To reduce the effect of increased observer experience with evaluation of each progressive sample, the order of assessment for the chicken samples was reversed for the second set of participants. To reduce this, participants were shown images of all markers immediately prior to the study. The use of sonographically visible breast tissue markers for ultrasound inconspicuous breast lesions allows access to the benefits of ultrasound targeting over the traditional requirement for stereotactic marker localisation.

We have demonstrated that there is considerable variability in the visibility of purported sonographically visible breast markers, and have reported comparative findings for six ultrasound markers.

Breast Tissue Markers: Biopsy Clip Markers

A breast marker is a tiny titanium or stainless steel marker, smaller than a sesame seed. Breast biopsy markers are placed during a breast biopsy procedure to identify the area where breast tissue was removed. Also, it will not set off metal detectors or security checkpoints when traveling. The marker has been tested and proven to be safe and effective. It has been used in biopsy procedures for over a decade.

The marker is designed so that once placed in the breast, it is unlikely to move. Allergic reactions to the marker are extremely rare. If you are allergic to metals, for example nickel, please inform your technologist.

No, the marker is not placed because you have cancer. It is simply a helpful tool used to identify the biopsy site. The tiny marker can be seen on future mammograms, which is beneficial to the radiologist reading your exam. Much like the Lotus flower, Digital Breast Tomosynthesis, also known as 3D Mammography, offers up exceptionally detailed images of the breast tissue in layers.
