PURPOSE
To evaluate whole-pancreas 3D-histogram ADC metrics in acute pancreatitis.
METHODS
In 41 patients with acute pancreatitis undergoing MRI/MRCP with DWI, 3D-volumes-of-interest encompassing the entire pancreas were placed to derive whole-pancreas histogram ADC metrics.
RESULTS
There were trends toward higher 0-10th percentile ADC, higher 10-25th percentile ADC, lower skewness, and higher kurtosis in patients with new complications (p=0.065-0.095). Conventional mean ADC showed no association with new complications (p=0.203). Kurtosis had highest area-under-the-curve (0.784) for predicting new complications (sensitivity=75.0%; specificity=91.9%).
CONCLUSION
Findings suggest whole-pancreas histogram ADC metrics assist early management of acute pancreatitis, (e.g., patient selection for more intensive monitoring/intervention).
目的
评估急性胰腺炎中全胰腺三维直方图ADC指标。
方法
对41例接受MRI/MRCP及DWI检查的急性胰腺炎患者，放置包含整个胰腺的三维感兴趣区，以得出全胰腺直方图ADC指标。
结果
新发并发症患者的ADC第0 - 10百分位数、第10 - 25百分位数有升高趋势，偏度降低，峰度升高（p = 0.065 - 0.095）。传统平均ADC与新发并发症无关联（p = 0.203）。峰度预测新发并发症的曲线下面积最高（0.784）（敏感性 = 75.0%；特异性 = 91.9%）。
结论
研究结果表明全胰腺直方图ADC指标有助于急性胰腺炎的早期管理（例如，选择患者进行更强化的监测/干预）。
