ECG Ordered Contrast Enhanced MRA
- Detailed Technology Description
- This invention is a method to acquire data while obtaining a magnetic resonance image, especially during contrast-enhanced MR scans. Data acquisition is coupled to the patient's heartbeat as in older methods, but in the Cornell method data is acquired continuously, as opposed to being acquired only during certain phases of the heartbeat. The result is higher resolution images taken in the same amount of time, compared to old methods.

- *Abstract
-
A robust electrocardiogram (ECG) ordering technique of k-space for breath hold contrast enhanced magnetic resonance angiography (CE-MRA) that acquires the central part of k-space in a motion-free portion of diastole and fills in from the periphery of k-space at all other times. To make maximal use of the contrast enhancement, data is acquired continuously even when the ECG signal is lost. The ECG signal is monitored in real time. The ECG ordering technique allows a flexible acquisition matrix and is robust against ECG signal imperfections. The ECG ordering technique allows thoracic and pulmonary magnetic resonance angiography with a higher resolution when compared to the conventional gated acquisition methods.
