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

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. 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. 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 CHIP and Hematological Toxicity After PRRT in Neuroendocrine Tumor Patients

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

   The overall objective of this project is to combine robust clinical data (e.g. prior chemotherapy or radiation exposure, cumulative radiotheranostic dose) with geneticclonal abnormalities (blood-based CHIP panel) in studying the predisposing risk factors for developing hematological toxicity including t-MN in radiotheranostic treated solid tumor patients.

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. Actinium Therapy For Late-stage Aggressive Sarcomas

   Rochester, Minn.

   The goal of this clinical trial is to learn about the safety of drug \[Ac225\]RTX-2358 and the diagnostic imaging agent \[Cu64\]LNTH-1363S. Additionally Ratio Therapeutics will learn if \[Ac225\]RTX-2358 drug is effective in treating advanced sarcoma.
   
   The main questions the study aims to answer in Phase/Part 1 of the trial are:
   
   * Is \[Ac225\]RTX-2358 tolerable or does it cause toxicities (medical problems) in patients.
   * What is the most tolerable dose of \[Ac225\]RTX-2358
   * Does the treatment show effectiveness on advanced sarcoma
   
   Participants will:
   
   * Take drug \[Ac225\]RTX-2358 once every 8 weeks (4 cycle target; 6 cycle maximum) over a period of 12 months
   * Visit the clinic three times for the first week of cycle one, then once a week for the remaining 7 weeks of cycle 1 for check-ups and tests.
   * For cycles 2-6: patient will visit the clinic once every 2 weeks for checkups and tests
   * Remain in long term follow-up for a period of four additional years

9. 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. 

    

    

    

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
