Clinical trials Below are current clinical trials.73 studies in Radiology (open studies only). Filter this list of studies by location, status and more. Evaluating Optic Nerve Disease with OCT Angiography Rochester, Minn. The purpose of this study is to determine if optical coherence tomography (OCT) angiography is able to distinguish different causes of optic neuropathy. Ultrasound Microvessel Imaging of Transplant Kidney Rochester, Minn. The purpose of this study is to investigate the value of ultrasound microvessel imaging for evaluation of transplant kidney health. Magnetic Resonance Elastography of Traumatic Brain Injury Rochester, Minn. This purpose of this pilot study is to determine if there are changes in mild TBI detectible with MRE. This is the first time this novel technology has been applied to mild TBI and the anticipated results are theoretical. A Study of Clinical Evaluation of a PET/MR System Rochester, Minn. The first objective of this pilot research protocol is to evaluate the quality of PET from the SIGNA PET/MR system and to compare the quantitative accuracy of PET images from the PET/MR system to PET images from a standard PET/CT system. The second objective of this pilot research protocol is to compare the image quality from MRI images acquired on the SIGNA PET/MR to clinical MR images acquired on a standard 3.0T MRI system. A Study To Develop A Patient-reported Outcome Tool For Symptomatic Small Bowel Stricturing Crohn’s Disease (CD) Rochester, Minn. The purpose of this study is to understand and document the concepts relevant and important to the measurement of signs, symptoms, and related experiences of patients living with stricturing CD for development of a new PRO instrument. A Study to Review Magnetic Resonance Imaging in Patients with Epilepsy Rochester, Minn. The primary purpose of this study is to compare the diagnostic utility of 7T MRI versus 3T MRI in the detection of subtle epileptogenic lesions in the brain. A Study to Evaluate Evacuation Mechanisms Using Advanced Brain Imaging Rochester, Minn. The objective of this study is to compare the central neural circuitry with fMRI (7T) in 30 asymptomatic healthy controls, 30 constipated patients without DD, and 30 constipated patients with DD at rest (functional connectivity analysis), during rectal distention to desire to defecate and urgency, and during evacuation. A Study to Assess Opioid-Induced Respiratory Depression Using Diaphragm Muscle Shear Wave Elastography Rochester, Minn. The purpose of this study is to determine the impact of opioid administration on diaphragm muscle forces during resting breathing and during higher force maneuvers by using a non-invasive shear wave elastography (SWE) method. Image-based Mapping Of Brain Tumors Scottsdale/Phoenix, Ariz., Rochester, Minn. The purpose of this study is to combine MRI images with histologic and genetic analysis of cancer (from blood and tissue samples) to improve the overall accuracy of diagnosis and effectiveness of cancer treatment. Assessment of the Mechanical Properties of Lung Parenchyma using Magnetic Resonance Elastography Rochester, Minn. The purpose of this research study is testing a new technique for measuring stiffness of the lung. This new technique is called Magnetic Resonance Elastography (MRE). In this study we will look at the stiffness measurements in humans.

The patient comes first. So the mission and research here is to advance how we can best help the patient, how to make sure the patient comes first in care. So in many ways, it's a cycle. It can start with as simple as an idea worked on in a laboratory, brought to the patient bedside, and if everything goes right — and let's say it's helpful or beneficial — then brought on as a standard approach. And I think that is one of the unique characteristics of Mayo's approach to research — that patient-centeredness — that really helps to put it in its own spotlight.
