Why the study?
Does ECG-gated MDCT reduce motion artifacts in the imaging of the thoracic aorta in a patient with type-A dissection?
Does ECG-gated MDCT reduce motion artifacts in the imaging of the thoracic aorta in a patient with type-A dissection?
ECG-gated MDCT effectively reduces motion artifacts in the thoracic aorta, improving diagnostic imaging quality for conditions such as type-A dissection.
May enhance diagnostic quality in type-A dissection CT; hypothesis-generating and requires prospective validation before practice change.
Multidetector computed tomography has been shown to be accurate in noninvasive assessment of chest vascular disease. The motion artifacts of the thoracic aorta and the supra-aortic vessels were significantly reduced in the electrocardiogram (ECG)-gated data acquisition. This positive effect of ECG synchronization is more pronounced in the region of the ascending aorta, aortic arch, and proximal descending aorta.
