按院区、状态和其他条件筛选该研究列表。

1. Potential Benefit of Photon-counting CT in Human Subjects

   Rochester, Minn.

   The purpose of this study is to to examine the ability of photon counting computed tomography (PCCT) to reduce calcium blooming and beam-hardening artifacts adjacent to bone, to use decreased dose levels without altering contrast-to-noise, and to improve discrimination of very small structures using the system’s increased spatial resolution.

2. 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.

3. 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. 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.

5. 3D Ultrasound Imaging for Breast Cancer Diagnosis

   Rochester, Minn.

   The purpose of this study is to evaluate the effectiveess of a new 3D ultrasound imaging technology combining B-mode, microvessel imaging, shear wave elastography, and machine learning for breast lesion diagnosis.

6. 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. 

    

    

    

7. Image-based Mapping of Brain Tumors

   Scottsdale/Phoenix, Ariz., Rochester, Minn.

   The purpose of this study is to combine MRI images with histologic and genetic analysis of cancer (from blood and tissue samples) to improve the overall accuracy of diagnosis and effectiveness of cancer treatment.

    

8. 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).

9. A Study to Evaluate CHIP and Hematological Toxicity After PRRT in Neuroendocrine Tumor Patients

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

   The purpose of this study is to combine robust clinical data (e.g., prior chemotherapy or radiation exposure, cumulative Peptide Receptor Radionuclide Therapy (PRRT dose)) with genetic and clonal abnormalities (blood-based CHIP panel) in studying the predisposing risk factors for developing hematological toxicity including t-MN in PRRT-treated neuroendocrine tumor (NET) patients.

10. 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
