按院区、状态和其他条件筛选该研究列表。

1. 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.

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. Training of Physicians in Critical Care Ultrasonography (CCUS)

   Rochester, Minn.

   The purpose of this study is to assess the improvement in physician’s knowledge and skill sets in ultrasonography after the implementation of simulation-based educational program.  

4. Prevalence of Transthyretin Cardiac Amyloidosis in Clinically Significant Aortic Stenosis

   Rochester, Minn.

   The purpose of this study is to determine the prevalence of TTR-CA in a community-based cohort of moderate and severe aortic stenosis patients using 99mTc-PYP single-photon positive emission computed tomography with computed tomography (SPECT/CT).

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. 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.

7. 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.

8. 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.

9. 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.
   
    

10. 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.
