Below are current clinical trials.

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

1. A Study of Change in Imaging Biomarkers of Dementia with Lewy Bodies (DLB) and Associations with Cognitive and Functional Decline

   Rochester, Minn., Jacksonville, Fla.

   Longitudinal Imaging Biomarkers of Disease Progression in Prodromal and Overt DLB

2. A Study to Evaluate Ultrasound Microvessel Imaging

   Rochester, Minn.

   The purpose of this study is to find out the optimal acquisition parameters for ultrasound microvessel imaging in healthy volunteers. 

3. A Study of Ticagrelor in the Upstream Setting for Non-ST-Segment Elevation Myocardial Infarction

   Jacksonville, Fla.

   The purpose of this study is to establish a registry that will address the data gap regarding the course of NSTEMI (Non-ST-Elevation Myocardial Infarction) between ED (Emergency Department) arrival and diagnostic angiography in detail, by characterizing and following the ED and peri-ED use of advanced OAP (Oral Anti-Platelet) agents. In addition to exploring ED treatment patterns and success of both ischemic and bleeding risk stratification prior to definition of the coronary anatomy, data generated via the UPSTREAM registry will allow plausible attribution of ischemic and bleeding outcomes to pre-catheterization antiplatelet therapy in the management of NSTEMI. This registry further seeks to demonstrate that contemporary use of upstream ticagrelor is associated with an economically-sound utilization of hospital resources, and smooth transition of care into the outpatient, secondary prevention setting for the first 30 days after hospitalization. Finally, it will allow characterization of patient selection factors and processes for ticagrelor vs alternative OAP agents, carrying out that descriptive comparison through discharge. Patients transferred in to an UPSTREAM hospital are eligible for inclusion, but the timing for OAP agent administration and diagnostic catheterization begin with ED care at the first hospital.

4. A Study to Collect Worldwide Pregnancy Data Following ExAblate Treatment of Symptomatic Uterine Fibroids

   Rochester, Minn.

   This study is being done to support a device labeling change that will allow women who have uterine fibroids and still wish to become pregnant greater access to the ExAblate treatment. In order for the Sponsor to receive permission to change the labeling, data regarding known pregnancies and their outcome are being gathered to show the known safety hazards to women who might wish to get pregnant after an ExAblate treatment

5. MR Elastography of Hydrocephalus

   Rochester, Minn.

   We are doing this research study to develop and test the effectiveness of a new imaging technique called magnetic resonance elastography (MRE). This technique measures the stiffness (mechanical properties) of the brain and cerebral spinal fluid.

6. A Study to Evaluate Noninvasive Ultrasound Elastography of Kidney and Lung in Assessment of Volume Status in ICU Patients

   Rochester, Minn.

   The primary purpose of this study is to assess the feasibility of performing lung and kidney and lung ultrasound elastography among patients with critical illness from different etiologies that could be associated with volume overload.

7. A Study of Lutetium Lu 177 Dotatate (Lutathera®) in Patients with Inoperable, Progressive Meningioma after External Beam Radiation Therapy

   Rochester, Minn.

   The purpose of this study is to estimate the efficacy of LUTATHERA treatment in patients with recurrent grade 1 meningioma as measured by 6-month PFS rate, and to estimate the efficacy of LUTATHERA treatment in patients with recurrent grade 2 or 3 meningioma as measured by 6-month PFS rate.

    

8. Medical and Resource Facilitation Intervention After Traumatic Brain Injury (MRFI)

   Rochester, Minn.

   The purpose of this study is to determine if there are changes in mild traumatic brain injury (mTBI) and/or repetitive head impacts (RHI) detectible with multiparametric MR Elastography (MRE). The hypothesis is that multiparametric MR Elastography will detect changes in the mechanical properties of human head tissues in patients following head traumas.

    

9. A Study of Endovascular Biopsy and Endothelial Cell Gene Analysis in Endovascular Procedures

   Rochester, Minn.

   The purpose of this study is to determine endothelial gene expression from guidewire biopsy during clinically indicated endovascular procedures. The genetic analysis will be measured against clinical outcomes and treatment response (response to non-coated and drug-coated technologies and different embolic agents depending on the procedure).

10. A Study to Assess Multiparametric MRI in Evaluating Cancer Stage and Helping Treatment Planning in Patients with Prostate Cancer

    Rochester, Minn., Jacksonville, Fla., Scottsdale/Phoenix, Ariz.

    The purpose of this study is to assess how well multiparametric magnetic resonance imaging (MRI) works in evaluating cancer stage and helping treatment planning in patients with prostate cancer. Multiparametric MRI may be useful for evaluating the type of cancer in finding aggressive disease.
