A 68-yeаr-оld pаtient is referred fоr а cardiac CT examinatiоn to assess the coronary arteries. During the pre-scan assessment, the radiographer observes that the patient's heart rate is 105 beats per minute and irregular, with intermittent variations between 95 and 115 beats per minute. The patient has a history of atrial fibrillation. Because of the irregular rhythm and relatively high heart rate, maintaining consistent cardiac-cycle timing during image acquisition is expected to be challenging. The radiographer must select an appropriate ECG-gating technique to minimize motion-related artifacts and obtain diagnostically useful images.Which ECG-gated acquisition technique should be considered in this patient, and why? [3]2. Explain why the patient's irregular rhythm may affect the quality of coronary CT images. [2]3. What is the main advantage of retrospective ECG-gated acquisition in this clinical situation? [2]
