Cardiac MRI stands for “Cardiac Magnetic Resonance Imaging.
In our department, a state-of-the-art magnetic resonance tomograph is available for cardiac diagnostics.
In this large, cylindrical tube surrounded by a circular magnet we can carry out magnetic resonance imaging examinations of the heart. With the help of computer calculations, an MRI provides images of the body tissue and blood flow- thus indicating any possible cardiological diseases. The procedure does not use X-rays, so you won’t be exposed to radiation during treatment.
The images captured with MRI are created by the interaction of several factors.
How cardiac MRI works.
MRI takes advantage of the high-water content of the human body. The procedure enables the hydrogen content in water molecules (H20), called protons (H+), to become visible.
Step 1: Magnetic Field.
For this, the tube of the MRI machine generates a static magnetic field. This aligns the protons in the body along the magnetic field in the tube.
Step 2: Impulse.
In the next step, a short electromagnetic pulse is generated, i.e., a second magnetic field. This deflects the aligned protons along the outer magnetic field.
Step 3: Measurement.
When the electromagnetic pulse is finished, the protons realign themselves along the magnetic field in the tube. In the process, the protons emit an electromagnetic signal that the MRI machine is able to measure. After leaving the MRI tube, the protons realign themselves to the state they were in before the examination.
