Due to its minimal risk, this new tool could be safely used with the same patient multiple times to better select the right treatment and find out early on if it is working. Project leader and partner Dr Rohan Dharmakumar, Associate Director of the Biomedical Imaging Research Institute at Cedars-Sinai Medical Center, believed that the noise was actually a variation in the heart39;s processing of oxygen.
Dr Prato noted that "with this new window into how the heart works, we have a lot to explore when it comes to the role of oxygen in health and disease.In addition to studying coronary artery disease, the method could be used in other cases where heart blood flow is affected such as the effects of a heart attack or damages to the heart during cancer treatment.Repeat exposure to carbon dioxide is used to test how well the heart39;s blood vessels are working to deliver oxygen to the muscle."Using MRI will not only be safer than plastic flowmeters z 500gglue series present methods but also provide more detailed information and much earlier on in the disease process," added Dr Prato.
Using MRI will not only be safer than present methods but also provide more detailed information. A breathing machine changes the concentration of carbon dioxide in the blood. There are small but finite associated risks and it is not recommended for a variety of patients including those with poor kidney function.
Following initial testing through clinical trials, he sees this being used with patients clinically within a few years."We39;ve opened the door to a new era and a totally novel way of doing cardiac stress testing to identify patients with ischemic heart disease. The cfMRI method reliably detects whether these changes are present. This change should result in a change in blood flow to the heart but does not happen when the disease is present. It eliminates the existing risks and can be used on all patients," said Dr Frank Prato, Lawson Assistant Director for Imaging.Currently, the diagnostic tests available to measure blood flow to the heart require the injection of radioactive chemicals or contrast agents that change the MRI signal and detect the presence of disease.

"This new method, cardiac functional MRI (cfMRI), does not require needles or chemicals being injected into the body."Our discovery shows that we can use MRI to study heart muscle activity. We39;ve been successful in using a pre-clinical model and now we are preparing to show this can be used to accurately detect heart disease in patients," explained Dr Prato. This approach overcomes the limitations of all the current diagnostics - there would no longer be a need for injections or physical stress testing like running on treadmills," said says Dr Dharmakumar.This new method, cardiac functional MRI (cfMRI), does not require needles or chemicals being injected into the body
