Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Acoustic Angiography | All clinical patients will be included in the experimental group.~Acoustic Angiography: Acoustic angiography imaging involves a research high frequency ultrasound scanner and a prototype transducer 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. The imaging also requires administration of Definity ultrasound contrast agent. | 0 | 3 | EG000 |
| Group 2 | Image Optimization | In addition to clinical patients, 30 participants will be recruited to aid in optimizing the imaging parameters.~Acoustic Angiography: Acoustic angiography imaging involves a research high frequency ultrasound scanner and a prototype transducer 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. The imaging also requires administration of Definity ultrasound contrast agent. | 0 | 15 | EG001 |
