Clinical Trial Summary

The BR-USCAD DS Module is a computer-assisted detection and diagnosis software based on a deep learning algorithm. This retrospective, fully-crossed, multi-reader, multi-case (MRMC) study aims to compare the performances of readers without and with the aid of the Breast Ultrasound Image Reviewed with Assistance of Computer-Assisted Detection and Diagnosis System (BR-USCAD DS) in interpreting breast ultrasound images of lesions.

Eligibility

Inclusion Criteria:

• B-mode breast ultrasound image

• Female, age 21 or older

• Breast lesion images acquired before a biopsy or surgery - these images were retrospectively collected with histology report.

• Non-biopsied benign lesions with negative follow-up for a minimum of 24 months

• At least two orthogonal views of a lesion

Exclusion Criteria:

• Breast lesion images acquired after biopsy or surgery.

• Any breast surgeries or interventional procedures in the 12 months prior to ultrasound imaging

• Case demonstrating administrative or technical errors

• Multiple lesions in one 2-D ultrasound image

• Breast ultrasound images with Doppler, elastography, or other overlays present

• Case with less than 2-year follow-up and without biopsy confirmation

Intervention

Diagnostic Test:
• Reader Group X - Session 1
Each rater in "Reader Group X" will interpret the "dataset A" cases in different random order without BR-USCAD DS and interpret the "dataset B" cases in different random order with BR-USCAD DS.
• Reader Group Y - Session 1
Each rater in "Reader Group Y" will interpret the "dataset A" cases in different random order with BR-USCAD DS and interpret the "dataset B" cases in different random order without BR-USCAD DS.
• Reader Group X - Session 2
Each rater in "Reader Group X" will interpret the "dataset A" cases in different random order with BR-USCAD DS and interpret the "dataset B" cases in different random order without BR-USCAD DS.
• Reader Group Y - Session 2
Each rater in "Reader Group Y" will interpret the "dataset A" cases in different random order without BR-USCAD DS and interpret the "dataset B" cases in different random order with BR-USCAD DS.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Comparing the Area Under the LROC Curve	The area under the LROC curve (AUC_LROC) on the diagnosis of benign and malignant lesions was computed and compared for Aim 1 (baseline) and Arm 2 (with BU-CAD assistance) studies.	10 weeks
Secondary	The Reading Time Was Computed and Compared for Aim 1 (Baseline) and Arm 2 (With BU-CAD Assistance) Studies.	Each reader's reading time of a case was automatically recorded by the BU-CAD system.; the average reading times of 16 readers with and without outlier reading times were compared between the aided and unaided sessions using the paired t-test.	10 weeks
Secondary	The Sensitivity, Specificity, PPV, and NPV Were Computed and Compared for Aim 1 (Baseline) and Arm 2 (With BU-CAD Assistance) Studies.	The mean sensitivity, specificity, PPV, and NPV of 16 readers were calculated and compared between the aided and unaided sessions using McNemar's test.	10 weeks
