For example "Motion" is the short label of "Motion artefact". Short label Alternative label Preferred label This predicate is used when something of interest is observed throughout the cardiac cycle. This predicate is used when something of interest is observed throughout a given cardiac cycle phase. This predicate is used when something of interest is observed at some point of the cardiac cycle. It is generic. This predicate is used when something of interest is observed at some point in a specific phase of the cardiac cycle.

Cardiac magnetic resonance artefacts, JCMR 2013). An artefact can also be defined as a feature appearing in an image that is not present in the original object (Erasmus LJ et al. A short overview of MRI artefacts, 2004).

This measure is most commonly computed for the left ventricle, sometimes for the right ventricle. Usually provided in grams. The myocardial mass of a given chamber (typically the LV) should be the same at each cardiac phase. Therefore, when there is a mismatch between the computed mass at ED and ES, it can be due to a image quality issue or (most likely) a countouring mistake. A mismatch of 5-10% is still acceptable due to the difficulty of contouring the endocardium in ES,especially when the papillary muscles are not included in the mass computation.

In general, it is not requested to specify pathology unless it is the suspected main cause of the quality issue. For example, arrhythmia causing mistriggering. Non-clinical users should only flag the presence of mistriggering as a technical issue.

SV=EDV-ESV Stroke volume is the difference in blood volume inside the ventricle between end diastole and end systole. Stroke volumes for the left and right ventricle should be approximately the same,with a 5-10% mismatch. Higher levels of mismatch can indicate either a technical issue (such as lack of coverage or artifact) or, less likely, a patient issue (such as pathology).
