Multi-Parametric MRI for Renal Transplantation
Starting soon
Conditions studied: Renal Transplant Rejection
In brief
The goals of this study are: * To optimize and evaluate multiple kidney MRI methods; and * To investigate the potential of MRI in the assessment of transplant kidney functions; To achieve these goals, we will perform pilot MRI studies with kidney transplant patients. We will study if MRI can reflect different levels of kidney function. The investigators will also evaluate if MRI can differentiate causes for declining kidney function. Finally, the investigators will explore how MRI measures changes before and after medical treatment for worsening kidney function. You may be invited for MRI exams with different exam options. An MRI exam may use either of two types of MRI machines at the center for magnetic resonance research (CMRR): the 3 Tesla (3T) scanner and the 7 Tesla (7T) scanner. You may also be invited for a multi-session exam. A description of the MRI exam types with different exam options and the types of multi-session exams is provided later in this document.

You may qualify if…
- Renal Transplant Recipients
- Capable to consent
- English speaking
- For studies with patients with fast worsening renal function: An abrupt (within 48 h) reduction in kidney function currently defined as a percentage increase in serum creatinine of ≥50% (1.5-fold from baseline), or a reduction in urine output (documented oliguria of less than 0.5 mL/kg/h for more than 6 h).
- For patients with recovered renal allograft function after therapy: renal allograft function as measured by glomerular filtration rate (eGRF) has been recovered and stabilized above a clinical acceptable level, such as 15 ml/min/1.73 mm2.
You may not qualify if…
- On dialysis due to renal allograft failure
- Acute and chronic pulmonary disease
