The aim of this study is to evaluate the efficacy and safety of contrast-free magnetic resonance angiography (MRA) for deep inferior epigastric perforator flap planning. The investigators propose to perform a non-contrast MRA to achieve the following extremely important objectives: to avoid radiation exposure, minimize the risk of potentially harmful effects of contrast agents, and reduce the cost of the study.The investigators assume that the use of non-contrast MRA following our protocol including certain patient's positioning, a special pulse scanning sequence and perforators' projection method is effective and allows mapping of perforators without injecting a potential harmful contrast agent.
