We would like to thank Zhu, Saloner, and Hope for their interest in our MA3RS study (Magnetic Resonance Imaging in Patients With Abdominal Aortic Aneurysm to Predict the Risk of Rupture or Surgery).1 They raise several important and interesting issues with regard to the study and the future application of such novel imaging strategies in patients with abdominal aortic aneurysms. Current clinical practice relies on the maximum anteroposterior diameter measured by ultrasound to guide patient management and subsequent surgical intervention. This unidimensional single measurement clearly has limitations. For example, serial ultrasound diameter measurements cannot capture proximal or distal extension of the aneurysm or …
