Below are current clinical trials.

Filter this list of studies by location, status and more.

1. Ultrasound Microvessel Imaging of Transplant Kidney

   Rochester, Minn.

   The purpose of this study is to investigate the value of ultrasound microvessel imaging for evaluation of transplant kidney health.

2. A Study to Evaluate Photon Counting Detector CT Utility in Identifying Acute Wrist Fractures.

   Rochester, Minn.

   The purpose of this study is to examine the ability of PCD-CT to (1) display subtle fractures of the wrist using the system’s increased spatial resolution compared to conventional wrist CT and MR; and (2)  evaluate the ability of PCD-CT with virtual non-calcium images to identify bone marrow edema at acute fracture sites.

    

3. A Study to Assess Biomarkers of Cerebral Cavernous Angioma with Symptomatic Hemorrhage (CASH)

   Rochester, Minn.

   The purpose of this study is to develop prognostic and diagnostic blood tests for symptomatic brain hemorrhage in patients diagnosed with cavernous angiomas, a critical clinical challenge in a disease affecting more than a million Americans. We further examine whether blood biomarkers can replace or enhance the accuracy of advanced imaging in association with lesional bleeding. The project tests a novel integrational approach of biomarker development in a mechanistically defined cerebrovascular disease, with a clinically relevant context of use.

4. Evaluating Highly Flexible (aka AIR) RF Coils for Patients Undergoing MR Imaging for Radiation Therapy Planning

   Rochester, Minn.

   To assess the quality of images obtained with a new RF (AIR) coil when compared to those obtained using FDA approved RF coils of patients undergoing MR imaging for radiation therapy treatment planning.

5. 3D Ultrasound for the Imaging of Axillary Lymph Nodes in Patients With Breast Cancer

   Rochester, Minn.

   The overall goal of this project is to study a new 3D ultrasound imaging technology for evaluation of axillary lymph nodes in patients with breast cancer.

    

6. Evaluating Optic Nerve Disease with OCT Angiography

   Rochester, Minn.

   The purpose of this study is to determine if optical coherence tomography (OCT) angiography is able to distinguish different causes of optic neuropathy.

7. Magnetic Resonance Elastography of Traumatic Brain Injury

   Rochester, Minn.

   This purpose of this pilot study is to determine if there are changes in mild TBI detectible with MRE. This is the first time this novel technology has been applied to mild TBI and the anticipated results are theoretical.

8. A Study of Clinical Evaluation of a PET/MR System

   Rochester, Minn.

   The first objective of this pilot research protocol is to evaluate the quality of PET from the SIGNA PET/MR system and to compare the quantitative accuracy of PET images from the PET/MR system to PET images from a standard PET/CT system. The second objective of this pilot research protocol is to compare the image quality from MRI images acquired on the SIGNA PET/MR to clinical MR images acquired on a standard 3.0T MRI system.

9. A Study to Review Magnetic Resonance Imaging in Patients with Epilepsy

   Rochester, Minn.

   The primary purpose of this study is to compare the diagnostic utility of 7T MRI versus 3T MRI in the detection of subtle epileptogenic lesions in the brain.

10. A Study to Assess Opioid-Induced Respiratory Depression Using Diaphragm Muscle Shear Wave Elastography

    Rochester, Minn.

    The purpose of this study is to determine the impact of opioid administration on diaphragm muscle forces during resting breathing and during higher force maneuvers by using a non-invasive shear wave elastography (SWE) method.
