1. Contrast-Enhanced MR Angiography Method in Comparison to Current Methods in Healthy Volunteers

   Rochester, Minn.

   The purpose of this study is to look at a contrast-enhanced MR angiography method in comparison to current methods. The contrast-enhanced method can generate images with more spatial detail and can be used to view a much larger region of the patient’s body than is presently possible.

2. A Study of Women undergoing Mammogram Screening at Mountain Park Clinic

   Rochester, Minn., Scottsdale/Phoenix, Ariz.

   The goal of this research is to identify risk profiles of women (with particular emphasis on Hispanic women) for breast cancer based on family history, breast density and other factors known to impact risk such as age, weight, age at menarche, age at birth of first child, etc.

3. Magnetic Resonance Elastography of Dementia

   Rochester, Minn.

   The purpose of this study is to develop and test the effectiveness of an investigational imaging technique called magnetic resonance elastography (MRE) to measure the stiffness (mechanical properties) of tissues.

4. Study to Assess Limited Magnetic Resonance Imaging in the Surveillance of Crohn's Disease

   Rochester, Minn.

   The purpose of this study is to compare a limited magnetic resonance enterography (MREN) to routine MREN in order to determine non-inferiority, missed findings, patient tolerance and impact on patient management. 

5. Improvements in Dynamic Contrast-Enhanced MR Angiography and Perfusion

   Rochester, Minn., Scottsdale/Phoenix, Ariz.

   The overall purpose is to study how a variety of technological approaches in Magnetic resonance imaging (MRI) can be used to provide improved performance non-contrast MR imaging as used for angiography and perfusion.  These include but are not limited to improvements in: (i) receiver coils; (ii) pulse sequences for data acquisition; (iii) methods for image reconstruction; (iv) algorithms for deriving MRI-based quantitative parameters and biomarkers.

6. A Study of the Possible Use of a New Imaging Method with Glioma Tumors

   Rochester, Minn., Scottsdale/Phoenix, Ariz.

   The purpose of this study is to see if Magnetic Resonance Elastography (MRE) a recently developed imaging technique can be used to characterize and help stage glioma tumors and evaluate response to therapy.

7. Magnetic Resonance Elastography of Myofascial Pain Syndrome

   Rochester, Minn.

   The purpose of this study is to develop MRE-based imaging biomarkers to measur the mechanical properties of the myofascial interface and determine if there are changes in these parameters in MPS patients and if these parameters can be used to monitor treatment responses and predict patient outcomes.

    

    

8. Quantitative Assessment of Tumor Ablation

   Rochester, Minn.

   The purpose of this study is to retrospectively analyze potential correlation between ablation zone/margin and tumor recurrence by using the Software Product to quantitatively evaluate diagnostic/pre-operative CT images, intra-operative CT images during ablation procedures, and follow-up CT images; and to apply and evaluate the FDA cleared Software Product during CT-guided ablation procedures for intra-operative monitoring and confirmation.
   
    

9. A Study to Determine the Tradeoffs between CT Image Quality and Patient Radiation Dose

   Rochester, Minn.

   The purpose of this study is to determine the tradeoffs between CT image quality and patient radiation dose in a way that moves beyond current simple models (e.g. standard deviation and CTDIvol) by investigating the relationships between task-based metrics of image quality, observer performance, patient size, and patient dose.

10. A Study to Assess Biomarkers of Cerebral Cavernous Angioma with Symptomatic Hemorrhage (CASH)

    Rochester, Minn.

    The purpose of this study is to develop prognostic and diagnostic blood tests for symptomatic brain hemorrhage in patients diagnosed with cavernous angiomas, a critical clinical challenge in a disease affecting more than a million Americans. We further examine whether blood biomarkers can replace or enhance the accuracy of advanced imaging in association with lesional bleeding. The project tests a novel integrational approach of biomarker development in a mechanistically defined cerebrovascular disease, with a clinically relevant context of use.

10. A Study to Evaluate Photon Counting Detector CT Utility in Identifying Acute Wrist Fractures.

    Rochester, Minn.

    The purpose of this study is to examine the ability of PCD-CT to (1) display subtle fractures of the wrist using the system’s increased spatial resolution compared to conventional wrist CT and MR; and (2)  evaluate the ability of PCD-CT with virtual non-calcium images to identify bone marrow edema at acute fracture sites.
