Plain English Summary

Background and study aims
A cardiac MRI scan is a non-invasive test where magnetic and radio waves are used to create pictures of the inside of the heart. Over the last couple of years cardiac MRI has become the gold standard method for looking at scars in the heart muscle. This scarring can be due to myocardial infarction (heart attack), thickening of the heart walls or inflammation of the heart muscle itself and is a very strong indicator of the likely course of these conditions. Cardiac MRI uses a technique called late gadolinium enhancement (LGE) to show scars. The gold standard LGE technique is a so-called segmented PSIR sequence and provides great image quality, but only in patients with a stable heart rhythm and able to hold their breath, which is required for the technique to work. Unfortunately, many patients do not meet these requirements. New so-called multi-slice LGE sequences are faster techniques than the gold standard method and also work for patients with irregular heart rhythm or shortness of breath. The aim of this study is to assess the accuracy of three of these novel multi-slice LGE sequences to detect and quantify scars in the heart muscle when compared to a gold standard PSIR sequence.

Who can participate?
Patients aged 18 and over referred for cardiac MRI after a heart attack (myocardial infarction), with thickened heart walls (hypertrophic cardiomyopathies), or due to suspected or known inflammation of the heart muscle cells

What does the study involve?
All participants undergo a standard cardiac MRI scan with the gold standard LGE PSIR sequence and also the new multi-slice sequences. This prolongs the MRI scan by about five minutes. The size of the myocardium (heart muscle) and image quality are compared between the scans.

What are the possible benefits and risks of participating?
Possible benefits include improved detection of scars in the heart muscle. If the multi-slice sequences are found to perform as well as the gold standard sequence, these faster sequences could be used in future to improve access to cardiac MRI by decreasing scan time at a high image quality and increasing patient comfort. As all patients receive the cardiac MRI even if they do not participate and the scan itself is only prolonged by 5 minutes (of a 45 minutes total scan time), there is no additional risk or burden expected with participation in this study.

Myocardial infarction, hypertrophic cardiomyopathy and inflammatory heart disease


This is an observational study in which three different techniques are compared for visualization of myocardial fibrosis using late Gadolinium enhancement in patients with known or suspected cardiomyopathy.

Patients sent for clinically indicated cardiac LGE-based MRI with known or suspected LGE due to chronic infarction, inflammatory myocardial disease and hypertrophic cardiomyopathy (HCM) are prospectively recruited. The indication for the MRI itself is clinical. However, for this study the MRI protocol is extended by the tested multislice LGE sequences for approximately 5 extra minutes. LGE images are acquired using three different LGE sequences. All patients were scanned with all three LGE sequences (intraindividual comparison). All LGE sequences are then assessed as follows: image quality is evaluated with a 4-point scoring system. Contrast-to-noise ratios and acquisition time are measured. Size of LGE is quantitatively assessed using a semi-automated threshold method. All assessments are done by blinded readers.
