Delphinus SoftVue™ ROC Reader Study (DMT SV RRS3) (DMT SV RRS3)

February 1, 2021 updated by: Delphinus Medical Technologies, Inc.

A Retrospective, Observational, Case-controlled, Multi-reader, Multi-case, Receiver Operating Characteristic (ROC) Study of Reader Performance When SoftVue Automated Breast Ultrasound (SV) and Digital Screening Mammography (DM) Are Combined, Compared to Screening Mammography Alone, in Asymptomatic Women With Heterogeneous or Extremely Dense Breast Parenchyma

The purpose of this multi-reader, multi-case (MRMC) reader study is to evaluate reader performance when SoftVue™ automated breast ultrasound and screening mammography are combined, compared to screening mammography alone, in women with dense breast parenchyma.

This reader study will include up to 32 radiologist readers and a sample of 140 breast screening cases that were selected from the library of images collected under Delphinus Protocol #DMT-2015.001 (NCT03257839) Arm 1 Phase B. The reader study image case set will be enriched with cancer cases.
