Cardiac Magnetic Resonance protocol and patient preparation

Abstract

The use of magnetic resonance imaging (MRI) in cardiovascular applications has improved with the development of the hardware systems of current MRI machines: very fast activation and deactivation of gradient, radiofrequency coils with high sensitivity and high gradient amplitudes. Cardiac magnetic resonance (CMR) is an imaging technique that allows for the evaluation of the structure and function of the heart. The standard CMR protocol includes the acquisition of both structural and functional images. Structural imaging is performed using T1 and T2-weighted imaging sequences, which allow for the visualization of the heart chamber walls, tissues, and any cardiac lesions or scars. Functional imaging sequences, on the other hand, enable the assessment of the heart's contractility and its ability to pump blood effectively. The CMR protocol is a highly customizable and flexible imaging method that provides detailed information on the structure and function of the heart, as well as any cardiac pathology. CMR is a safe and non-invasive imaging technique, but requires highly skilled personnel and specialized equipment to be performed correctly.
