1. A Study to Evaluate the Effects of Distortion Reduction Software for Improving Image Quality in Computed Tomography (CT) Scans

   Rochester, Minn.

   The primary purpose of this study is to evaluate the effectiveness of automatic adaptive iterative metal artifcate reduction (AiMAR) in improving image quality in CT scans of different body parts in patients with different metal implants in terms of artifact reduction and visualization of key anatomic structures.

2. A Study to Investigate the Use of Diaphragm Muscle Ultrasound to Assess the Duration of a Diaphragm Nerve Block

   Rochester, Minn.

   The purpose of this study is to to determine the impact of anesthesia (liposomal bupivacaine) on diaphragm muscle forces using a non-invasive ultrasonographic shear wave elastography (SWE) method.  

3. Evaluation of the Total Kidney Volume AI Algorithm

   Rochester, Minn.

   The natural course of autosomal dominant polycystic kidney disease (ADPKD) is highly variable and typically characterized by progressive enlargement of cysts within the kidneys.  ADPKD is a leading cause of end-stage renal disease.  Recently, a new medication called Tolvaptan has been approved by the FDA to slow progression of ADPKD.  Accurate, MR based kidney volume measurements are the best parameter for following the progression of ADPKD, and are suggested be acquired to measure progression and effects of Tolvaptan.  However, making these slice-by-slice volume measurements can be extremely time consuming when done manually.  The purpose of this work is to evaluate an AI algorithm to make the measurements.  The results of the algorithm will be reviewed by a qualified radiologist familiar with the algorithm’s results.  If the radiologist agrees with the results, kidney volumes (left, right and combined) will be recorded for clinical use.  The usage of the algorithm in this setting (with review by radiologist, and manual correction) is a minimal risk to the patients: a failure of the algorithm will have no impact on treatment and errors will be caught and corrected by the QC process. Because the algorithm will not be used solely for diagnosis or inform treatment without the confirmation of the diagnosis by another, medically established diagnostic product or procedure this study constitutes minimal risk to patients. 

4. A Study to Evaluate Screening Contrast Enhanced Digital Mammogram (CEDM) in Study Participants at Intermediate Breast Cancer Risk and Polygenic Risk Score (PRS) Results

   Rochester, Minn.

   The purpose of this study is to evaluate a low-cost Contrast Enhanced Digital Mammogram (CEDM) protocol as a supplemental screening method to standard mammographic screening in women at intermediate lifetime-risk (and not undergoing annual MR surveillance) for breast cancer.

    

    

    

    

5. A Study of Demyelinating Lesions as a Cause of Progressive Motor Deterioration

   Rochester, Minn.

   The purpose of this study is a comprehensive review of the clinical and radiologic history in these patients as well as review of neuropathology in deceased patients, where available.  The goal of this research is to investigate the hypothesis that this presentation represents a spatially limited form of CNS inflammatory demyelinating disease.

6. A Study to Evaluate MR of CSF Dynamics

   Rochester, Minn.

   The purpose of this study is to evaluate changes in CSF dynamics (e.g., velocity, flow rate) between patients with normal pressure hydrocephalus and healthy controls, as well as patients with other dementia disorders.

7. A Study to Assess an MRI Image Localizer for 7T MRI Neuronavigation

   Rochester, Minn.

   The purpose of this study is to develop a localizer for use within the 7T MRI to allow for future clinical use in neurosurgical planning.

8. A Study to Compare Two Ultrasound-based Methods for Assessing Diaphragm Muscle Function

   Rochester, Minn.

   The purpose of this study is to assess and compare the utility of ultrasonographic shear wave elastography (SWE) method as compared to “ABCDE” thickening ratio and fraction method in assessing diaphragm function.

9. Retrospective Review of Radiological Findings of Uterine Leiomyosarcoma in Comparison with Those of Atypical Leiomyoma

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

   The purpose of this study is to retrospectively review the imaging findings of the uterine leiomyosarcoma and compare with those of atypical leiomyoma.

10. Improving the Quality of Magnetic Resonance Imaging (MRI) Examinations

    Rochester, Minn.

    The purpose of this research study is to improve the quality of Magnetic Resonance Imaging (MRI) examinations.
