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

1. A Study to Evaluate and Monitor Hepatitis Activity in Hepatitis C Virus Infection Patients Using Advanced Multiparametric MR Elastography (MRE)

   Rochester, Minn.

   The purpose of this study is to develop an advanced multiparametric liver magnetic resonance elastography (MRE) imaging technology for monitoring hepatic inflammation during direct acting antiviral (DAA) treatment, evaluation risks of severe liver injury, and HCC development.

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. A Study of 3-D Digital Mammography to Screen Patients for Breast Cancer

   Rochester, Minn., Scottsdale/Phoenix, Ariz.

   The purpose of this study is to evaluate digital tomosynthesis (3-D) mammography and digital mammography in screening patients for breast cancer. Screening for breast cancer with tomosynthesis mammography may be superior to digital mammography for breast cancer screening and may help reduce the need for additional imaging or treatment.

4. 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.

5. A Study to Evaluate Neuroimaging of Men with Migraine

   Scottsdale/Phoenix, Ariz.

   The purpose of this study is to find sex-based differences in migraine-related functional connectivity. To achieve this, men with migraine will be compared to men healthy controls and women with migraine will be compared to women healthy controls.

   Men and women with migraine will then be compared, using region-pairs that differed in the single-sex comparisons.  Identification of migraine-related, sex-specific, functional imaging aberrations will provide insights into sex-specific migraine pathophysiology and will inform future imaging studies

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. A Study to Evaluate Ultrasound Imaging in Renal Transplant Recipients

   Jacksonville, Fla.

   The purpose of this study is to determine the effectiveness of ultrasound elastography in prediction of renal allograft fibrosis.        

9. A Study Using Magnetic Resonance Imaging (MRI) as a Non-invasive Method for Assessing Pancreatic Fibrosis (MINIMAP)

   Rochester, Minn.

   The purpose of this study is to evaluate magnetic resonance imaging (MRI) as a non-invasive imaging method to detect chronic pancreatitis (CP) and quantify pancreatic fibrosis.

10. Partnership for Early Detection of Alzheimer's Disease Using Advanced MR Technology

    Rochester, Minn.

    The primary objective of this application is to establish the feasibility of widespread clinical use of advanced MRS technology for early AD diagnosis in a strategic alliance between MR physicists at the UMN and physician scientists at Mayo Clinic.
