Post-mastectomy autologous breast reconstruction using abdominal perforator flaps gained popularity because it offers a natural soft breast mound, and preserves the donor site muscle and function. Because the vascular anatomy of the abdominal wall is highly variable between individuals, a detailed accurate preoperative vascular map of the abdomen can significantly reduce the operating time, with a better surgical outcome. MDCTA proved to be very useful for this purpose [1], however it requires ionizing contrast agents and radiation. the purpose of this work was to investigate the role of non-contrast enhanced MR angiography (NC-MRA), as compared to MDCTA, in the preoperative evaluation of the vascular anatomy of the abdominal wall for abdominal perforator flap surgery in post-mastectomy breast reconstruction.
