Automated Whole Breast Ultrasound

Mary W Yamashita, MD

The SoftVue™ is a whole breast ultrasound system with an automated scanning curvilinear ring-array transducer that employs UST. It is currently cleared under FDA 510(k) K123209 and K142517 for use as both a B-mode ultrasonic breast imaging system and color imaging of transmission data (sound speed and attenuation). SoftVue™ is not intended to be used as a replacement for screening mammography.

SoftVue uses non-ionizing ultrasound energy to generate tomographic image volumes of the whole breast. While the patient lays prone on a padded table with one breast comfortably submerged in a bath of warm water, a ring-shaped transducer, 22 cm in diameter, encircles the breast and pulses low-frequency sound waves through the water and into the breast tissue. More than 2000 elements in the curvilinear transducer's 360 degree array emit and receive ultrasound signals to analyze echoes from the breast anatomy in all directions, from the chest wall to the nipple. Not only does SoftVue capture data from the reflection of the sound waves off of tissue boundaries and structures within the breast, but because the transducer surrounds the whole breast, SoftVue also captures signals that are transmitted through the breast. This additional transmission data enhances the visualization of the anatomic structure of the breast tissue and is not currently available in any other commercially marketed breast ultrasound device.

This prospective, multicenter, multi-arm, clinical case collection program is IRB-approved and will be conducted in compliance with Good Clinical Practice, the Declaration of Helsinki and all applicable regulatory requirements. Arm 1 aims to collectively enroll up to 17,500 women at a total of up to 8 clinical sites. The design of this protocol is strictly limited to case collection; all investigational and statistical plans for future analyses will be prepared and registered separately, if they are applicable to the requirements of FDAAA 801.

Arm 1 is limited to the cohort of asymptomatic women, with heterogeneously or extremely dense breast parenchyma (BI-RADS breast composition category c or d). Matched triads of 2D digital mammography (FFDM), 3D digital mammography (DBT), and SoftVue automated whole breast ultrasound (SV)exams, from the same patient, with demographic information and clinical outcome data, will be collected during the same screening imaging episode. Ultrasound characteristics for all types of lesions, whether they are benign or malignant, will be collected, as well as objective and subjective breast density composition data.

The exams and clinical data accumulated in this prospective case collection (PCC) protocol will populate a database from which future investigations may be designed for peer reviewed publication, development of user training curriculums, building teaching case, and creating new marketing materials for SoftVue.A subset of exams will be sampled from Arm 1 for use in ROC Reader Study (protocol DMT-2015.002), which will be separately registered and is designed to evaluate the safety and efficacy of a new screening indication for use of SoftVue™ as an adjunct to screening mammography. The results of this ROC Reader Study will be submitted to the FDA for their consideration of a PMA application for SoftVue.

Robert M Uzenoff

The purpose of this pilot is to assess the adequacy of the Fujifilm DBT Reader Study Training program to ensure that Readers participating in the Fujifilm DBT pivotal trial are properly trained in the reading and interpretation of FFDM and DBT images.

For this reader study, radiologists review images obtained via protocol FMSU2013-004A. They review both FFDM alone and FFDM + DBT images, and provide a BI-RADS and POM for each. The radiologists performance metrics for the following modalities will be evaluated: FFDM and FFDM + DBT.

A Multi-Reader Multi-Case Controlled Clinical Trial to Assess the Adequacy of the Fujifilm Full Field Digital Mammography (FFDM) and Digital Breast Tomosynthesis (DBT) Reader Training Program - A Pilot Study

This endpoint was evaluated qualitatively. Reported the number of readers meeting the Pass Criteria on the final FFDM plus DBT assessment case set, which requires adequate performance in cancer cases (detection rate) as well as non-cancer cases (recall rate). Per-subject BI-RADS, POM and recall scores were derived. Credit was only given for identifying a subject with cancer if the reader marked findings in at least one location with cancer. Findings that did not match the location of a malignant lesion were ignored for cancer cases in the per-subject analyses.

The magnitude and direction of differences between performance metrics for the two modalities, and variance components and correlations that would influence sample size and case mix for the pivotal reader study (FMSU2013-004G) comparing performance metrics between the two modalities, obtained using established methods for analysis of MRMC (multi-reader, multi-case) studies. The statistician estimated AUC's for each reader in each review condition based on per-subject POM scores requiring correct lesion localization. Statistician performed MRMC comparison of AUC's between reading conditions using the MRMC analysis of variance (ANOVA) method.

The aim of this recruitment plan (ADAPT-SCR) is to collect image and other data on both digital breast tomosynthesis (DBT) and full-field digital mammography (FFDM) from asymptomatic women undergoing screening mammography.

ADAPT program consists of 2 recruitment plans (ADAPT-SCR and ADAPT-BX) followed by an off-line read of the images and data collected (ADAPT-BIE). This study involves the comparison of two devices that can identify abnormalities in routine breast screening and diagnostic mammography. Mammography is usually done with full-field digital mammography (FFDM), which takes flat, two-dimensional X-ray images of the breast. Doctors use the two-dimensional images to look for cancers and other abnormal tissue. The purpose of this study is to learn more about the accuracy of full-field digital mammography devices and a new mammography device called digital breast tomosynthesis (DBT). DBT is similar to full-field digital mammography, but can also move around the breast to get X-ray images from different angles, which provides a three-dimensional view that doctors can use to look for cancers and abnormal tissue. Subjects will undergo routine imaging with FFDM and will also have a DBT performed. They will continue with their standard of care treatment as would occur outside of the study. Based on the results of the FFDM and DBT, the subject's status will be followed-up with routing imaging at approximately 1 year (10-16 months). If the doctor recommends biopsy based on the FFDM or DBT, information about the biopsy and cancer determination results will be collected. Being in this study does not require subjects to have a biopsy that was not recommended by the doctor for normal medical care.

The purpose of this pilot is to provide credible performance estimate information in order to conduct subsequent reader studies.

This pilot reader study was to determine the following:

1. the radiologist's performance metrics for the two reading modalities, i.e., "FFDM read on the Aspire Bellus workstation" and "FFDM read in conjunction with DBT read on the Aspire Bellus workstation",;
2. the magnitude and direction of differences between performance metrics for the two modalities; and
3. variance components and correlations that would influence samples sizes and case mix for the subsequent pivotal reader study comparing performance metrics between the two modalities.

Statistician to provide graphical representations of each reader's ROC curve for each review condition. For each reader the difference between the AUC for the FFDM read in conjunction with the FFDM plus DBT will be presented. Statistician to perform MRMC comparison of AUC's between FFDM read in conjunction with FFDM plus DBT using the MRMC method of Dorfman, Berbaum \& Metz (1992).
