Valentina Carapella Ernesto Jimenez-Ruiz UMLS semantic group UMLS semantic type UMLS semantic type Id Short label, possibly incomplete, but ocurring in quality assessment annotations to refer to an entity. 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 might affect either the basal or apical part of the ventricles. We refer to this incorrect stack acquisition as "lack of coverage". Not fully covered Lack of coverage LA Left atrium LV Left ventricle 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. Apex of the heart Heart apex Left ventricular apex Left ventricle apex LV base Left ventricle base Midventriculular region of the left ventricle LVOT Left ventricular outflow tract LAX Long axis view Hardware related artefact Machine related artefact PROC Research Activity T062 Medical imaging study Mid slice Midventricle Midventricular region Incomplete Missing Incomplete data Missing data Motion Motion artefact Motion ringing Motion ringing artefact 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.

Observer Off resonance artefact Off-resonance artefact ANAT Body Part, Organ, or Organ Component T023 Organ ANAT Body Part, Organ, or Organ Component T023 Organ component 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=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).
