DCE-MRI对肥大乳房乳头乳晕复合体血供的评估价值OA

Objective To explore the value of dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)in assessing blood supply to the nipple-areola complex(NAC)in breast hypertrophy.Methods The DCE-MRI data of 107 patients with breast hypertrophy(the observation group)and 100 volunteers with normal breast(the control group)admitted to our hospital from January 2024 to January 2025 were retrospectively analyzed.The blood supply vessels to NAC were identified by maximum intensity projection(MIP)images,and the blood supply sources were counted according to the 9-region method.Results The single-region blood supply rate of the breasts in the observation group was significantly higher than that in the control group(P<0.05).The dual-region blood supply was the most common blood supply pattern for the breasts in both groups.No statistically significant differences were found between the two groups in the rates of dual-zone or three-or-more-region blood supply(P>0.05).There was no statistically significant difference in the regional distribution of NAC blood supply in the breasts between the two groups(P>0.05).The blood supply regions of the breasts in both groups were mainly concentrated in the inner upper quadrant and the outer upper quadrant.Conclusion DCE-MRI can clearly display the NAC blood supply characteristics of breast hypertrophy.The NAC blood supply pattern in breast hypertrophy is similar to that in normal breasts,while the proportion of single-region blood supply is significantly higher than that of normal breasthan.Preoperative assessment of DCE-MRI can help guide the design of surgical incisions and vascular protection,thus reducing the risk of NAC necrosis after surgery.
