![]() Breasts with any malignant lesions or lesions of unknown significance or with benign mass lesions more than 10 mm in diameter were also excluded from this study because of the possible deformation effect on the overall breast shape. Breasts that had undergone any surgical operation or other therapeutic intervention were excluded because of possible deformation effects after these procedures. The clinical records of the patients were reviewed for information about their prior history of breast surgical procedures. Breast MRI scanning was performed in a total of 88 patients and a total of 175 breasts (1 women had undergone a unilateral mastectomy for breast cancer and only had a left breast). The purpose of the present study was to clarify the changes in breast shape related to aging using MR images acquired while the subject was in a prone position.Īfter obtaining institutional review board approval, data from our previous breast MRI studies, which were performed between March and August 2013, were analyzed in this study. An investigation of such changes in the breast is likewise important to improve breast-conserving surgery, breast reconstruction, and reshaping or rejuvenating surgical procedures.Īlthough several studies have investigated the relationship between aging and changes in the breast parenchymal tissue using mammography 6– 10 or MRI, 11 the relationship between aging and breast shape has not been previously reported. Hoenig et al 5 has clarified the relationship between aging and morphologic changes in the buttocks. Understanding the changes in body shape that accompany aging is also important to help surgeons identify the surgical techniques that are needed in a given case. 4 Although breasts are pulled ventrally by gravity during MRI procedures, they are far less influenced by caudal transformation than they are in a daily upright position. Image acquisition in the prone position is also a characteristic of breast MRI examinations. MRI examinations of the breast are highly sensitive for the detection of breast cancer 2, 3 and are being used in large populations (such as patients with a high risk of breast cancer), for preoperative breast surveillance, and for problem solving. Objective assessments of the shapes of various parts of the body can be made using images acquired with multidetector row computed tomography 1 or magnetic resonance imaging (MRI). An understanding of breast morphology is needed to improve the aesthetic outcomes of various surgical procedures involving the breast.
