目的探讨LAVA（快速容积成像）序列在子宫肌瘤经高强度聚集超声（hIFU）治疗后疗效评估中的价值。方法应用GE Signa hDe 1.5T超导型磁共振LAVA MASK（平扫）和LAVA动态增强技术，观察经hIFU治疗前后的83例子宫肌瘤患者（共117个肌瘤）病灶信号的变化，从而对治疗效果进行评价。结果106个肌瘤术后病灶信号发生明显改变，表现为凝固性坏死，LAVA MASK信号增高，LAVA动态增强扫描显示病灶血供明显减少；11个肌瘤术后病灶信号及LAVA MASK信号改变不大，LAVA动态增强扫描显示病灶血供未见明显改变。结论LAVA序列在子宫肌瘤经hIFU治疗后疗效评估中起着极其显著的作用。
目的探討LAVA（快速容積成像）序列在子宮肌瘤經高彊度聚集超聲（hIFU）治療後療效評估中的價值。方法應用GE Signa hDe 1.5T超導型磁共振LAVA MASK（平掃）和LAVA動態增彊技術，觀察經hIFU治療前後的83例子宮肌瘤患者（共117箇肌瘤）病竈信號的變化，從而對治療效果進行評價。結果106箇肌瘤術後病竈信號髮生明顯改變，錶現為凝固性壞死，LAVA MASK信號增高，LAVA動態增彊掃描顯示病竈血供明顯減少；11箇肌瘤術後病竈信號及LAVA MASK信號改變不大，LAVA動態增彊掃描顯示病竈血供未見明顯改變。結論LAVA序列在子宮肌瘤經hIFU治療後療效評估中起著極其顯著的作用。

Objective To discuss the value of LAVA (Liver Acceleration Volume Acquisition) sequence in evaluating effects of high-intensity focused ultrasound (HIFU) on hysteromyoma. Methods LAVA MASK and LAVA enhanced-dynamic-scan were performed by gE Signa HDe 1.5T MR system on 83 patients with hysteromyoma (a total of 117 myomata) before and after HIFU to observe lesions signal and evaluate the effects of HIFU treatment. Results By analyzing the results, we found that signals of 106 myomata clearly changed and were characterized by coagulation necrosis, LAVA MASK signal increased, and LAVA enhanced-dynamic-scan displayed signiifcant decrease in blood-supply. Besides, the rest 11 myomata MRI signal showed littler change before and after HIFU treatment as well as LAVA MASK signal, LAVA enhanced-dynamic-scan displayed blood-supply not changes signiifcantly. Conclusion LAVA sequence plays a very important role on evaluating the effects of HIFU treatments.
