Pressure measurements (by manometry) and magnetic resonance imaging (MRI) are widely used for diagnosis in patients with constipation or fecal incontinence. This study is trying to improve the utility of these tests for diagnosing these problems and to understand if pressure measurements (by manometry) can be related to strength of the anal sphincter measured by MRI. The purpose of this study is to better understand the mechanisms by which people retain control of their bowel contents and evacuate stool (defecation) and why people have constipation or fecal incontinence (involuntary stool leakage). Improving Anorectal Testing for Defecatory Disorders and Fecal Incontinence.The purpose of this study is to evaluate the detection rates of MRI-targeted prostate biopsies compared to standard 12-core trans-rectal ultrasound guided (TRUS) prostate biopsies for prostate cancer. A Study of MRI-Targeted Biopsy Compared to Standard Ultrasound Guided Biopsy for the Diagnosis of Prostate Cancer.At Mayo, we will be looking at new MRI 'sequences' in addition to the usual sequences to see if that helps determine which cavernous malformations may bleed again. To do this we will be assessing the quality of MRI and data collection from patients with cavernous malformations across multiple sites in the country. The purpose of this study is to set up the infrastructure for future clinical trials for patients with cavernous malformations.

Study of Trial Readiness in Cavernous Angiomas with Symptomatic Hemorrhage (CASH).The result of these studies will be used to validate new technology to determine the iron level in the brain and correlate the iron deposit with age, gender, and pathology. The significant testing by vendor and Mayo staff prior to in vivo use, assure the safety of these studies and overall system stability. This proposal includes evaluation of brain iron quantification method using MR imaging and will operate within the NSR guidelines for data acquisition established by the FDA/CDRH. The purpose of this study is to investigate the extent to which advanced MRI measurements can help predict brain signals measured with intracranial electrodes. A Study to Evaluate Advanced MRI Imaging to Predict Intracranial Signals in Humans.
