3-D Super Resolution Ultrasound Microvascular Imaging

October 24, 2023 updated by: UNC Lineberger Comprehensive Cancer Center

High Frame Rate 3-D Super Resolution Ultrasound Microvascular Imaging

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Breast Imaging Cohort
A total of 15 women with known breast lesions that are already scheduled to undergo a clinical biopsy
Perflutren will be administered in split doses using the dosing range and administration type IV bolus) within the perflutren prescribing information. When administered as a bolus, the package insert recommends 10 uL/kg patient weight administered within 30-60 seconds, followed by a 10mL saline flush with a second dose of 10 uL/kg patient weight 30 minutes following the first dose, if needed.
Other Names:
  • perflutren

Acoustic angiography imaging involves a research ultrasound scanner as well as conventional b-mode ultrasound to guide the location of the imaging. The conventional ultrasound will be conducted just prior to the acoustic angiography for localization. Imaging will be performed within the package insert guidelines for ultrasound system mechanical index (a measurement of output power) when imaging perflutren contrast agent (less than 0.8).

Acoustic angiography imaging will be performed by trained medical personnel using mild compression to eliminate motion. Total imaging time is estimated to be less than 15 minutes.

Experimental: Thyroid Imaging Cohort
