1_Regardless of the size, thickness or density of the breast, the CMUT transducer can penetrate all tissue layers from the skin surface right through to the pleura and ribs.It is a fundamental requirement to image the breast parenchyma thoroughly and identify the interface with the pectoral muscle without the need for multiple system adjustments or probe changes.

CMUT technology offers high perceptibility particularly when looking for subtle, deep seated lesions identified on a mammogram, MRI, tomosynthesis or ultrasound examina-tions referred from another clinic.

Conventional breast ultrasound techniques use high-frequency transducers which compromise ultrasound penetration in the dense or large breast demanding the use of an additional lower frequency probe.

2_The benefit of CMUT breast ultrasound combines high frequency imaging and fluid interpretation with fast image processing; this unique technological advantage allows for a confident ultrasound examination of the breast deemed challenging (Type IV density, post-surgery, large breast volume, prosthesis).These advantages are also relevant for confidently scanning the underarm where opti-mal contrast between fatty tissue and adenopathy, normal or pathological conditions is paramount.Extensive ultrasound exploration with precise visualization of vascular structures also plays an important role during underarm ganglion biopsy.From the initial breast ultrasound examination and Identification of possible pathology, subsequent lymph node biopsy under ultrasound guidance is a universal procedure.

Conclusions Whether breast ultrasound is performed in a Breast Cancer Unit or as part of a routine examination, the ARIETTA 850 in combination with CMUT is a unique and innovative solution:

It benefits from:

Signal to noise ratio

High-Frequency imaging

Precise differentiation between tissue interfaces

Increases diagnostic understanding in complex cases (eg fatty tissue)

Significant ultrasound penetration

Superior image interpretation regardless of breast size or density.

A single probe solution that can confidently detect subtle lesions that are often deep seated, confirming location and characterization in order to simplify excision where required.By eliminating the need to change probes or repeat ultra-sound examinations, ultimately saves the operator time and can significantly increase precision levels.

About Dr. Laurent SimoniIn my senology centre, I perform more than 30 breast examinations per day, often together with a mammo-gram and tomosynthesis. I use ultrasound scans also review MRI results and check the position of a lesion for targeting.
