1. Assessment of the Mechanical Properties of Lung Parenchyma using Magnetic Resonance Elastography

   Rochester, Minn.

   The purpose of this research study is testing a new technique for measuring stiffness of the lung. This new technique is called Magnetic Resonance Elastography (MRE). In this study we will look at the stiffness measurements in humans.

2. Ferromagnetic Detection of Cardiac Devices using a Metrasens Screener

   Rochester, Minn.

   The purpose is to conduct a study that determines the efficiency of FMDS in pre MRI screening for detecting cardiac implants in a Mayo Clinic environment.

4. A Study to Evaluate Evacuation Mechanisms Using Advanced Brain Imaging

   Rochester, Minn.

   The objective of this study is to compare the central neural circuitry with fMRI (7T) in 30 asymptomatic healthy controls, 30 constipated patients without DD, and 30 constipated patients with DD at rest (functional connectivity analysis), during rectal distention to desire to defecate and urgency, and during evacuation. 

    

    

    

5. A Study to Evaluate Improving PET Image Quality and Quantification by Using Motion Correction, Parametric Imaging and MAP Reconstruction

   Rochester, Minn.

   
   The aims of this research project are to assess the effectiveness of motion correction software for patients undergoing PET brain scans, to assess the data acquisition and image processing workflow for parametric analysis of brain and whole body scans, and to assess the quality of PET images reconstructed with maximum a posteriori (MAP) reconstruction algorithm.

6. 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

7. 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. 

8. 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.

2. Detection of Vascular and Inflammatory Plasma Biomarkers in Patients Diagnosed with Obstructive Sleep Apnea and MRI-defined Cerebral Small Vessel Disease

   Jacksonville, Fla.

   The purpose of this study is to evaluate plasma biomarkers of vascular function and inflammation in patients with newly-diagnosed Obstructive Sleep Apnea (OSA) and pre-existing imaging evidence of Cerebral Small Vessel Disease (CSVD).

4. A Study to Evaluate Evacuation Mechanisms Using Advanced Brain Imaging

   Rochester, Minn.

   The objective of this study is to compare the central neural circuitry with fMRI (7T) in 30 asymptomatic healthy controls, 30 constipated patients without DD, and 30 constipated patients with DD at rest (functional connectivity analysis), during rectal distention to desire to defecate and urgency, and during evacuation.

   Rochester, Minn.

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

9. 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.
