1. 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.

6. 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.

7. Determinants of Incident Stroke Cognitive Outcomes and Vascular Effects on Recovery (DISCOVERY)

   Rochester, Minn.

   The purpose o fthis study

   A total of 8,000 patients presenting to CPSs with acute-onset AIS, ICH or aSAH and no history of dementia will be enrolled within 6 weeks of stroke onset.

   All participants will undergo baseline screening for evidence of pre-stroke dementia. Those who pass baseline screening will complete a blood draw and a series of cognitive and functional assessments at baseline.

   Participants will undergo in-person (3-6 months, 18 months) and telephone (annual) follow-up visits for the duration of the study to assess for longitudinal cognitive and functional outcomes. In addition to Tier 1 procedures, at each in-person follow-up visit: Tier 2 participants will also undergo MRI scanning, comprehensive cognitive assessment batteries and longitudinal blood collection; and Tier 3 participants will also complete amyloid- and tau-PET/CT scans.

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. A Study to Predict Sepsis-Associated Acute Kidney Injury by Assessing Renal Microvascular Blood Flow and Elasticity with Contrast-Enhanced Ultrasonography and Ultrasound Elastogram

   Rochester, Minn.

   The purpose of this study is to assess kidney microcirculation using contrast-enhanced ultrasonography associated with kidney ultrasound elastography among patients who are at risk of sepsis-associated acute kidney injury provides strong predictive ability for AKI and potential therapeutic targets. 

    

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.
