Study Design
Allocation: Non-Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Diagnostic
Name: Computed Tomography and Mammography and Tomosynthesis
Type: Radiation
Overall Status
The purpose of this study is to compare the imaging performance of an investigational breast computed tomography (CT) scanner, built at UC Davis, with that of an FDA-Approved breast tomosynthesis scanner (capable of producing standard 2-D mammography and 3-D tomosynthesis images), built by Hologic, Incorporated, in a group of patients with suspected breast cancer.
Detailed Description
The primary aim of this study is the comparison of tumor conspicuity on images taken by both systems (computed tomography versus standard 2-D mammography versus 3-D tomosynthesis) using a ten point conspicuity scale as the end-point. Secondary aims will be to compare the number of lesions detected by the two systems, and to compare the estimated radiation dose of the two systems.
