Figure 3c. Normal appearance of a TRAM flap at MR imaging. (a) Axial T1-weighted image of both breasts shows complete fatty composition of the left breast. For comparison, note the normal glandular tissue in the right breast. (b) Sagittal T1-weighted image of the TRAM flap shows the atrophied rectus abdominis muscle anterior to the chest wall (*). The denuded dermal layer of the abdominal tissue (arrows) is seen parallel to the skin of the breast. (c) Corresponding mediolateral oblique mammogram shows the muscular pedicle (*).
