Clinical Studies

Open

  • Assessment of Metabolic Bone Disease of Prematurity Using an Acoustic Method (PREM-BONE) Rochester, Minn.

    The purpose of this study is to develop and validate a new ultrasonic method for assessment of infant bone by evaluating structural and mechanical characteristics of infant tibia.

  • Classification of Breast Masses Based on Visco-elastic Properties Using SAVE Method Rochester, Minn.

    The purpose of this research is to evaluate the efficacy of a new breast tissue assessment tool that provides new diagnostic information about breast masses and potential for early classification of malignant masses.

    This study is being done to:

    • Test an investigational breast imaging system;

    • Image the breast and see if we can differentiate lesions by using the investigational imaging system;

    • Test an investigational breast stiffness measurement method

    • Test and compare to an FDA approved ultrasound stiffness imaging system (GE LOGIQ E9 (LE9)

    • Compare to ultrasound images using Alpinion clinical ultrasound platform, FDA approved ECUBE 12 and a non-FDA approved ECUBE 12R

     

  • Identification and Differentiation of Thyroid Nodules by Acoustic Imaging and Viscoelastic Parameters Rochester, Minn., Scottsdale/Phoenix, Ariz.

    The purpose of this research study is to evaluate imaging methods for detection and differentiation of thyroid nodules.

  • PAD - Ultrasonic Peripheral Perfusion Imaging Rochester, Minn.

    The purpose of this study is to evaluate the potential of ultrasound perfusion imaging technique for assessing the progression of peripheral arterial disease (PAD) and monitoring its response to therapy by measuring changes in microvessel alterations and perfusion variations.

  • Treatment monitoring of carpal tunnel syndrome using Shear Wave Elastography: A pilot in vivo study (SWE) Scottsdale/Phoenix, Ariz.

    As CTS is the most commonly diagnosed compression neuropathy of the upper extremity, assessment of severity and treatment response is important crucial to determine the clinical outcomes. Currently, physical examination and overall functional status as well as pre-op electrodiagnostic (EDX) testing are important in determining patient outcome scores and assessing the treatment response. The physical properties of MN and surrounding tissue may be good biomarkers for this evaluation.

    SWE is a qualitative and quantitative method for measuring tissue stiffness. There are limited studies on using SWE for diagnosis of CTS , but other aspects of CTS, including the assessment of severity and treatment response have not been studied. Our central hypothesis is that SWE provides quantitative information about the physical properties of the MN and surrounding tissue that help to identify carpal tunnel syndrome, its severity and response to treatment. If SWE successfully demonstrates efficacy in diagnosing, patient outcome score, and treatment response assessment, it would have a significant clinical impact on patients with CTS, as well as offering an additional confirmatory diagnostic test for true recurrent carpal tunnel syndrome.

  • VASD - Combined Acoustic Imaging and Viscoelastic Parameters Estimation in Breast Cancer (VASD) Rochester, Minn.

    The purpose of this research is to optimize and evaluate the efficacy of a hybrid imaging and quantitative viscoelasticity measurement tool for breast cancer detection and monitoring.
