目前公认多参数磁共振成像(multi-parametric magnetic resonance imaging,mpMRI)是检出PCa最佳的影像学检查方法,随着相关临床研究的深入及前列腺影像报告和数据系统(Prostate Imaging Reporting and Data System,PI-RADS)的更新完善,剔除了动态...
Dynamic contrast enhanced MRI (DCE-MRI) is performed after injection of a contrast agent. Usually the low molecular weight contrast agents (e.g. gadopentetate dimeglumine, Gd-DTPA) are used. MR sequences can be designed to be sensitive to the vascular phase of contrast medium delivery, so-cal...
Introduction:European Association of Urology and UK National Institute for Health and Care Excellence guidelines recommend that all men with suspicions of prostate cancer should undergo prebiopsy contrast enhanced, that is, multiparametric prostate MRI. Subsequent prostate biopsies should also be performed ...

In contrast to fusions biopsies, in-bore MRI guided biopsy cannot combine targeted biopsy to systematic biopsy. All methods were carried out in accordance with relevant guidelines. Therefore, all patients were offered a systematic biopsy. The decision for a systematic biopsy before or after the ...
Furthermore, strong enhancement of contrast fluid in CT- and MRI-scans is seen both in meningioma cells and neighbouring normal tissue like the cavernous or sagittal sinus. Therefore a trimodal image fusion using CT, MRI and positron emission tomography (PET) has been established for treatment ...
Breast cancer is the most frequent cancer in women and remains the second leading cause of death in Western countries. It represents a heterogeneous group of diseases with diverse tumoral behaviour, treatment responsiveness and prognosis. While major pro
To detect csPCa, three mpMRI “components” are used: “anatomic” T2-weighted imaging, “cellular-density” diffusion-weighted imaging, and “vascularity” dynamic contrast-enhanced MRI. 为了检测csPCa,术者应用了三个mpMRI的相关技术:“解剖结...
一项研究对2 690 例儿童期癌症患者进行配对分析,发现孕期诊断性辐射性影像学检查不会明显增加儿童期肿瘤(OR=1.14,95%CI:0.90~1.45)和白血病的发生率(OR=1.36,95%CI:0.91~2.02)[1]。但也有回顾性资料显示,早孕期10~20 mGy 的胎儿辐射暴露剂量...
