1. 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. 

2. A Study to Evaluate Potential Myocardial Injury Following Magnetic Resonance Imaging (MRI)

   Rochester, Minn.

   The purpose of this study is to prospectively determine if magnetic resonance imaging (MRI) in patients with cardiac implantable electronic devices (CIED) results in myocardial injury as assessed by changes in high sensitivity cardiac troponin T (hs-cTnT) assay. This will be done by comparing pre-and-post MRI hs-cTnT levels in these patients.

3. 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.

4. 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.

5. 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.

6. 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.

7. 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.
   
    

8. 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.

    

    

9. 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.

10. A Clinical Use Application for the Humanitarian Use Device Exemption Use Protocol of TheraSphere for Treatment of Unresectable Primary or Secondary Liver Neoplasia

    Eau Claire, Wis.

    This protocol allows multiple treatments with TheraSphere® that may be delivered on an outpatient basis. Patients may receive a single dose to a liver lobe or segmental treatment delivered as a sequence of treatments approximately 30-90 days apart. The principal clinician, working with a multidisciplinary team, will develop a specific treatment plan for each patient, based upon the presenting condition of the patient, the vascular anatomy and the desired goal of treatment.
