Translation of Acoustic Angiography: Contrast Enhanced Super Resolution (CESR) Imaging

NCT07225114 · Status: RECRUITING · Phase: PHASE2 · Type: INTERVENTIONAL · Enrollment: 40

Last updated 2026-01-06

No results posted yet for this study

Summary

This is a 4-arm, single-center study involving 40 participants. Ten healthy volunteers will be enrolled for system imaging optimization, and thirty (30) patients with previously identified lesions in the breast, liver, or kidney-based on prior ultrasound or cross-sectional imaging-will be imaged. Recruitment will be conducted such that ten patients are included from each anatomic region.

The fourth arm will consist of 10 healthy volunteers who will be imaged to allow optimization of imaging parameters. Optimization is is required again due to the use of a different ultrasound system employing a new imaging technique. Parameters such as frame rate, power, depth of imaging, and linear translation rate will be adjusted during this process.

The primary objectives of the study are to assess the sensitivity and specificity of Contrast Enhanced Super-Resolution (CESR) imaging in evaluating known lesions in the breast, liver, and kidney. These results will be compared with pathological findings. The secondary objectives are to compare the sensitivity and specificity of CESR imaging with those of traditional B-mode ultrasound in differentiating malignant from benign lesions in these same organs.

Conditions

Interventions

DRUG

contrast agent perflutren lipid

At the time of imaging, the contrast agent perflutren lipid will be administered, intravenous (IV). All patients will be visually monitored for signs or symptoms of a contrast administration reaction once the drug is administered for a 15-minute period.

DEVICE

Ultrasound Imaging

Contrast Enhanced Super Resolution (CESR) 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 CESR imaging for localization.
