3-D Super Resolution Ultrasound Microvascular Imaging

Phase 2
Active, not recruiting
Conditions
Breast Cancer
Thyroid Cancer
Interventions
Device: Acoustic Angiography
Registration Number
NCT04136912
Lead Sponsor
UNC Lineberger Comprehensive Cancer Center
Brief Summary

This is a 3-arm single center study of 45 patients. These cohorts will include 15 breast patients scheduled to undergo a biopsy, and 15 thyroid patients scheduled to undergo fine needle aspiration, biopsy, or thyroidectomy that consent to undergo an acoustic angiography in conjunction with b-mode ultrasound prior to their scheduled biopsy. Prior to imaging clinical patients, the third arm will include 15 healthy volunteers that will be imaged to optimize imaging parameters.

Detailed Description

Increasing the sensitivity and specificity of diagnostic imaging in patients at high risk for breast or thyroid cancer could provide substantial clinical benefit by improving diagnosis, preventing over-treatment, and reducing healthcare costs. Acoustic angiography is a new type of contrast enhanced ultrasound imaging which is specifically sensitive to microvascular structure and density. It evaluates tumor micro-vasculature and may provide a powerful prognostic tool for the diagnosis of breast cancer, and eventually for treatment evaluation.

Primary Outcome Measures
NameTimeMethod
Sensitivity of Acoustic Angiography; Thyroid Imaging (percent of positive scans)Calculated once all imaging is complete [Anticipated 1.5 years]

Sensitivity of Acoustic Angiography in the analysis of know thyroid lesions will be evaluated by comparing image analyses to the pathological results for these lesions.

Specificity of Acoustic Angiography; Thyroid Imaging (percent of negative scans)Calculated once all imaging is complete [Anticipated 1.5 years]

Specificity of Acoustic Angiography in the analysis of know thyroid lesions will be evaluated by comparing image analyses to the pathological results for these lesions.

Sensitivity of Acoustic Angiography; Breast Imaging (percent of positive scans)Calculated once all imaging is complete [Anticipated 1.5 years]

Sensitivity of Acoustic Angiography in the analysis of know breast lesions will be evaluated by comparing image analyses to the pathological results for these lesions.

Specificity of Acoustic Angiography; Breast Imaging (percent of negative scans)Calculated once all imaging is complete [Anticipated 1.5 years]

Specificity of Acoustic Angiography in the analysis of know breast lesions will be evaluated by comparing image analyses to the pathological results for these lesions.

Secondary Outcome Measures
NameTimeMethod
Radiologist preference (Arbitrary units)Calculated once all imaging is complete [Anticipated 1.5 years]

To compare radiologist preference of acoustic angiography to conventional b-mode ultrasound for each lesion characteristic (shape, margins, and vascularity)

Area Under the Curve of Acoustic Angiography (arbitrary units)Calculated once all imaging is complete [Anticipated 1.5 years]

To compare the area under the curve (AUC) of acoustic angiography to the AUC of the b-mode ultrasound

Sensitivity of acoustic angiography compared to conventional ultrasound: Thyroid (arbitrary units)Calculated once all imaging is complete [Anticipated 1.5 years]

To compare (using a reader study) the sensitivity of acoustic angiography to the sensitivity of conventional b-mode ultrasound in evaluation of known thyroid lesions for predicting malignancy.
