IMPRoving Outcomes in Vascular DisEase- Aortic Dissection Not Recruiting
The goal of this clinical trial is to determine whether an upfront invasive strategy of TEVAR plus medical therapy reduces the occurrence of a composite endpoint of all-cause death or major aortic complications compared to an upfront conservative strategy of medical therapy with surveillance for deterioration in patients with uncomplicated type B aortic dissection.

Diagnostic Performance of Coronary CT Angiography With CT FFR in Kidney Transplantation Candidates Not Recruiting
Patients with chronic kidney disease (CKD) before kidney transplantation require that obstructive coronary artery disease (CAD) is excluded, as cardiovascular complications are the leading cause of mortality in kidney transplant patients. However, in this patient population, the optimal method for the detection of obstructive CAD has not been identified. Noninvasive stress tests such as Dobutamine stress echocardiography or nuclear perfusion study have low diagnostic accuracy. CT fractional flow reserve measurement (CT FFR) is a novel non-invasive (FDA approved) imaging test to identify obstructive CAD. The goal of this project is to evaluate the diagnostic accuracy of CT FFR in the detection of obstructive coronary artery disease in patients with chronic kidney disease before kidney transplantation.

Limiting AAA With Metformin (LIMIT) Trial Recruiting
In this research, the investigators are looking at the effects of a drug called metformin may have on the growth of abdominal aortic aneurysm (AAA)s. AAA is an abnormal enlargement of the aorta, which is the large artery in the abdomen (stomach area). The enlargement of the aorta carries a risk that it will rupture and cause life-threatening bleeding in the abdomen (belly). In this study the investigators hope to learn how metformin is associated with the enlargement or change in size of the AAA in study participants. Smaller studies have suggested that metformin may reduce the rate at which aortic aneurysms enlarge. This study will test this question: does metformin prevent AAAs from growing larger?

Prospective, multi-center study to assess safety and performance of the Edwards EVOQUE Tricuspid Valve Replacement System
Perfusion CT as a Predictor of Treatment Response in Patients With Hepatic Malignancies Not Recruiting
A research study of liver perfusion (how blood flows to the liver over time). We hope to learn whether perfusion characteristics of liver masses may be predictive of response to treatment and whether liver perfusion characteristics can be used to follow response to treatment.

Perfusion CT as a Predictor of Treatment Response in Patients With Rectal Cancer Not Recruiting
A research study of rectal cancer perfusion (how blood flows to the rectum over time). We hope to learn whether perfusion characteristics of rectal masses may be predictive of response to treatment and whether rectal perfusion characteristics can be used to follow response to treatment.

Prognostic Value of Baseline Computed Tomography (CT) Perfusion Parameters of Pancreatic Cancer for Patients Undergoing Stereotactic Body Radiotherapy or Surgical Resection Not Recruiting
The purpose of this study is first, to determine whether baseline perfusion characteristics of pancreatic cancer, as characterized by CT perfusion studies, can predict tumor response to treatment by stereotactic body radiotherapy (SBRT). The second goal of this study is to determine whether baseline perfusion characteristics in those patients with resectable pancreatic cancer correlate with immunohistologic markers of angiogenesis such as microvessel density and vascular endothelial growth factor (VEGF) expression.

Perfusion CT Monitoring to Predict Treatment Efficacy in Renal Cell Carcinoma Not Recruiting
This pilot clinical trial studies perfusion computed tomography (CT) in predicting response to treatment in patients with advanced kidney cancer. Comparing results of diagnostic procedures done before, during, and after targeted therapy may help doctors predict a patient's response to treatment and help plan the best treatment.
