Past, Present and Future Perspective of Cardiac Magnetic Resonance Imaging; Basic Techniques and Technical Advances
Sigurdur Sigurdsson Icelandic Heart Association

To review the basic techniques used in Cardiac Magnetic Resonance Imaging (CMRI) and give an overview of technical developments in CMRI from past to present. To discuss potential techniques and applications in acquisition and post-processing.

CMRI continues to advance rapidly both from a clinical and technical perspective. Although MRI has been used in cardiac research applications for more than a decade, hardware and software advances have pushed CMRI into a more mainstream population in the most recent years. These advances include substantial improvements in temporal and spatial resolution along with a reduction in motion artefacts with a consequent improved depiction of myocardial outlines, coronary arteries and contrast enhancement for wall motion, coronary artery stenosis, myocardial viability and perfusion analysis. Parallel imaging, multi-channel radiofrequency coils and not least advances in pulse sequences are some of the key elements that have lead to the overall image quality improvements in CMRI and opened for the evolution of CMRI in the clinical society. Further technical advances in CMRI may make it possible to distinguish between calcified and lipid plaques and even allow interventional applications in the near future.
