Clinical Benefits of B-Flow Ultrasound

Evaluation of Clinical Benefits of B-Flow With the LOGIQ E9 Ultrasound System

The goals of this study are to evaluate the efficacy of the B-flow capability on the LOGIQ E9 system in three clinical focus areas.

1. Liver transplant patients: Improved real-time visualization of liver vessels is needed to improve diagnosis and assessment following stenting or angioplasty.
2. Renal artery disease: Improved real-time visualization of the renal arteries would enable a more rapid and accurate assessment of renal artery disease (stenosis, dissection, occlusion, aneurysm) and facilitate follow-up evaluations after renal artery interventions.
3. Pregnancy: We are proposing to use B-flow ultrasound as a way to evaluate placenta perfusion and assay for potential ischemia.

Inclusion Criteria:

Subjects must be referred for a standard clinical ultrasound exam.

• Patients who have had a Liver Transplant and are referred for a liver ultrasound or angioplasty & stent placement;
• Patients with hypertension, impaired renal function, or renal artery disease who are referred for a renal ultrasound or angioplasty & stent placement;
• Pregnant women referred for an obstetrical ultrasound to evaluate a normal pregnancy for example to determine gestation or gestational age;
• Pregnant women referred for an obstetrical ultrasound to evaluate a high risk pregnancy due to a medical condition present before or during pregnancy for either the mother or the baby.

Exclusion Criteria:

• Minors;
• Prisoners;
• Unable to understand the nature of the study or to consent;
• Very sick or experiencing significant pain;
• Undergoing an emergency ultrasound;
• Pregnant and undergoing an ultrasound to evaluate suspected congenital malformation, abruptio placenta or fetal death.
