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.
Thresholds for LA and LV diameter on nongated CTA can be chosen to provide specific, but not sensitive, detection of LAE and LVE.
