The world's first use of magnetic resonance imaging to study heart damage
Magnetic resonance imaging (MRI) and kidney disease experts performed the first scan to study the cardiac function of patients undergoing dialysis treatment.
People with kidney failure require regular dialysis to remove fluids and waste from their blood, but this process can lead to a drop in blood pressure and a decrease in blood flow to the heart. Over time, this can lead to long-term damage to the heart.
The University of Nottingham study aims to investigate heart pressure during kidney dialysis and compare two different types of dialysis: standard hemodialysis (HD) and hemodiafiltration (HDF), which removes more fluid during treatment. But the patient got extra replacement fluid.
Experts at the Peter Mansfield Imaging Center (SPMIC) and the Center for Kidney Research and Innovation (CKRI) underwent MRI scans of 12 patients with renal dialysis who were randomized to receive HD and HDF.
The study found that standard hemodialysis and HDF had a significant cardiovascular effect, but there was no difference between the two. The results show that cardiac MRI is an important tool for improving future dialysis treatment.
Sue Francis, a professor of physics, said: "This is the first time that MRI has been used to observe the heart function of kidney patients undergoing dialysis. We need to overcome several obstacles to achieve this. We have to set up an dialysis machine at the MRI Research Center. Replace the metal needle that enters the patient's body with a non-magnetic silicone, extend the wire insulation that connects the patient to the dialysis machine, and use the magnetic field knowledge to locate the device MRI unit.
