摘要

目的:超高b值弥散加权成像(DWI)提高前列腺癌的诊断价值。高b值的DWI提高了前列腺癌的诊断能力。高b值的DWI提高了前列腺癌的诊断能力。高b值的DWI提高了前列腺癌的诊断能力。更高材料和方法的DWI。15例患者(7例恶性,8例良性)经机构伦理委员会批准回顾性纳入本研究。所有图像均在3T MR扫描仪上获取。ADC值采用单指数模型计算。高b值的合成ADC (sADC)提高了前列腺癌的诊断能力。DWI更高。结果:实际ADC与sADC的b值增高对前列腺癌的诊断能力无显著差异。DWI在sDWI中的p=0.002,配对t检验)高于DWI。sDWI与DWI相比,恶性病变sADC明显低于良性病变(p=0.002,配对t检验)。恶性病变的sADC明显低于良性病变(讨论/。结论:我们的初步研究表明,高b值对应的ADC值可以使用由低b值(b≤1000)导出的对数线性关系来计算。我们的方法可以帮助临床医生确定前列腺病变的最佳b值。b值提高前列腺癌的诊断能力。高b值的DWI提高了前列腺癌的诊断能力。高b值的DWI提高了前列腺癌的诊断能力。高b值的DWI提高了前列腺癌的诊断能力。DWI更高。

Synthetic Apparent Diffusion Coefficient for High b-Value Diffusion-Weighted MRI in Prostate.

Purpose: It has been reported that diffusion-weighted imaging (DWI) with ultrahigh b-value increases the diagnostic power of prostate cancer. DWI with higher b-value increases the diagnostic power of prostate cancer. DWI with higher b-value increases the diagnostic power of prostate cancer. DWI with higher b-value increases the diagnostic power of prostate cancer. DWI with higher Materials and Methods. Fifteen patients (7 malignant and 8 benign) were included in this study retrospectively with the institutional ethical committee approval. All images were acquired at a 3T MR scanner. The ADC values were calculated using a monoexponential model. Synthetic ADC (sADC) for higher b-value increases the diagnostic power of prostate cancer. DWI with higher.

Results: No significant difference was observed between actual ADC and sADC for b-value increases the diagnostic power of prostate cancer. DWI with higher p=0.002, paired t-test) in sDWI as compared to DWI. Malignant lesions showed significantly lower sADC as compared to benign lesions (p=0.002, paired t-test) in sDWI as compared to DWI. Malignant lesions showed significantly lower sADC as compared to benign lesions (Discussion/.

Conclusion: Our initial investigation suggests that the ADC values corresponding to higher b-value can be computed using log-linear relationship derived from lower b-values (b ≤ 1000). Our method might help clinicians to decide the optimal b-value for prostate lesion identification.b-value increases the diagnostic power of prostate cancer. DWI with higher b-value increases the diagnostic power of prostate cancer. DWI with higher b-value increases the diagnostic power of prostate cancer. DWI with higher b-value increases the diagnostic power of prostate cancer. DWI with higher.
