MRI Scans Better Than CT Scans For Heart Patients

People who suffer from heart diseases and conditions, as well as those suspected of this, and who have received a recommendation for a heart X-ray, should ask for a Magnetic Resonance Imaging (MRI) over other scanning options.

This is the suggestion of researchers from the University of Leeds in the United Kingdom.

It would have a double impact on the assessment of coronary heart diseases’ patients. It would mean not only preferring MRI scans over other non-invasive methods such as Computerised Tomography scans (CT scan) but also it would suggest MRI’s superiority as an assaying tool over other invasive techniques such as angiogram, ballooning (stretch and stent) or SPECT, etc.

Suspected cases of coronary heart diseases are referred for further tests to assess type, location and extent of damage. Coronary heart diseases (CHD) refers to a condition where the coronary arteries of a person narrow down or clog completely due to deposition of fatty substances and cholesterol in the arterial walls. This blocks the flow of blood into the heart and causes heart attack.

While MRIs use radio waves, CT Scans and SPECT use ionising radiation to arrive at internal anatomical/structural imagery thus exposing both the patient and the radiologist to unnecessary radiation. Invasive tests such as angiography involve the injection of dye into the arteries of the heart to be able to get the correct imagery of the dye route. (1)

The study, which ran over a period of five years at the University of Leeds and involved the participation of over 750 CHD patients, concluded that MRI scans were a safe and reliable way to detect signs and the extent of CHD presence.

The technical findings of the research can be had in the December, 2011 issue of the medical journal The Lancet. (2) The results may now lead health care policy-makers to re-think guidance as to the tests that patients with suspected CHD should be offered.

As per Dr John Greenwood who led the study, “We have shown convincingly that of the options available to doctors in diagnosing coronary heart disease, MRI is better than the more commonly-used SPECT imaging test.
