Below are current clinical trials.

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

1. Minnesota Spinal Cord Injury Data Network

   Rochester, Minn.

   This is a study to generate feasibilty data regarding the collection of health and psychosocial outcomes after acquired spinal cord injury (SCI)

2. A Study to Evaluate the Effects of Distortion Reduction Software for Improving Image Quality in Computed Tomography (CT) Scans

   Rochester, Minn.

   The primary purpose of this study is to evaluate the effectiveness of automatic adaptive iterative metal artifcate reduction (AiMAR) in improving image quality in CT scans of different body parts in patients with different metal implants in terms of artifact reduction and visualization of key anatomic structures.

3. 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).

4. A Study to Investigate the Use of Diaphragm Muscle Ultrasound to Assess the Duration of a Diaphragm Nerve Block

   Rochester, Minn.

   The purpose of this study is to to determine the impact of anesthesia (liposomal bupivacaine) on diaphragm muscle forces using a non-invasive ultrasonographic shear wave elastography (SWE) method.  

5. A Study to Evaluate Shared Decision Making for Patients with Minor Head Injury

   Rochester, Minn.

   The primary purpose of this study is to understand the effect of educating patients and encouraging shared decision making on rates of CT scanning in head injured patients by using an already developed app and observing the effect on the health care provider

    

6. A Study of Demyelinating Lesions as a Cause of Progressive Motor Deterioration

   Rochester, Minn.

   The purpose of this study is a comprehensive review of the clinical and radiologic history in these patients as well as review of neuropathology in deceased patients, where available.  The goal of this research is to investigate the hypothesis that this presentation represents a spatially limited form of CNS inflammatory demyelinating disease.

7. Determinants of Incident Stroke Cognitive Outcomes and Vascular Effects on Recovery (DISCOVERY)

   Rochester, Minn.

   The purpose o fthis study

   A total of 8,000 patients presenting to CPSs with acute-onset AIS, ICH or aSAH and no history of dementia will be enrolled within 6 weeks of stroke onset.

   All participants will undergo baseline screening for evidence of pre-stroke dementia. Those who pass baseline screening will complete a blood draw and a series of cognitive and functional assessments at baseline.

   Participants will undergo in-person (3-6 months, 18 months) and telephone (annual) follow-up visits for the duration of the study to assess for longitudinal cognitive and functional outcomes. In addition to Tier 1 procedures, at each in-person follow-up visit: Tier 2 participants will also undergo MRI scanning, comprehensive cognitive assessment batteries and longitudinal blood collection; and Tier 3 participants will also complete amyloid- and tau-PET/CT scans.

8. A Study to Predict Sepsis-Associated Acute Kidney Injury by Assessing Renal Microvascular Blood Flow and Elasticity with Contrast-Enhanced Ultrasonography and Ultrasound Elastogram

   Rochester, Minn.

   The purpose of this study is to assess kidney microcirculation using contrast-enhanced ultrasonography associated with kidney ultrasound elastography among patients who are at risk of sepsis-associated acute kidney injury provides strong predictive ability for AKI and potential therapeutic targets. 

    

9. Clinical Evaluation and Deployment of a Clinical PET/MR System with a Data Registry

   Jacksonville, Fla.

   The purpose of this study is to assess and deploy a new PET/MR platform following the same quality control method as was done at other Mayo Clinic sites, i.e. Rochester and Arizona.
   
   The secondary purpose is to initiate a data registry for the PET/MR studies allowing us to capture some basic information about the indications, findings, and relevant imaging and non-imaging biomarkers for the studies conducted. This will allow us to see trends in utilization as well as create preliminary data to inform future (IRB approved) investigations.

10. Improving the Quality of Magnetic Resonance Imaging (MRI) Examinations

    Rochester, Minn.

    The purpose of this research study is to improve the quality of Magnetic Resonance Imaging (MRI) examinations.
