Why the study?
Does non-ECG-gated Computed Tomography Angiography of the chest accurately detect left-sided cardiac chamber enlargement?
Does non-ECG-gated Computed Tomography Angiography of the chest accurately detect left-sided cardiac chamber enlargement?
Non-ECG-gated chest CTA can be used to specifically, though not sensitively, detect left atrial and left ventricular enlargement.
Offers specific but insensitive detection of LAE/LVE on nongated CTA; leaves open routine clinical use pending validation.
Thresholds for LA and LV diameter on nongated CTA can be chosen to provide specific, but not sensitive, detection of LAE and LVE.
