Artefact
Artifact
An artefact can be defined as something that is visible in an image but it is artificial, and is often detrimental to diagnosis (Ferreira, PF et al. 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).

Issue
An issue is observed in a view, chamber and cardiac cycle. Optionally one may define more fine grained description (if it applies) about concrete chamber location (e.g., apex) or if single or multible slices were affected.

At acquisition time, the short axis stack might not cover the whole extent of the ventricles. This might affect either the basal or apical part of the ventricles. We refer to this incorrect stack acquisition as "lack of coverage".

The left ventricular apex is considered a synonym of the heart apex. The right ventricle has its own apex, which at the moment is not specified in the ontology because it is never referred to in the quality assessment process.

Mass
The amount of tissue contained between endocardial and epycardial layers for a given chamber, usually excluding papillary muscles or trabeculations. 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.

Comments regarding presence of pathology should only be provided by clinically trained users. 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
Stroke volume is the difference between end diastolic and end systolic volumes, for a given chamber. 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).
