研究目的:

本研比较5T磁共振与3T磁共振在前列腺癌MRI引导下靶向穿刺活检中的诊断价值与临床效能,具体目标如下:1.评估两种磁共振系统的图像质量差异,包括信噪比(SNR)、空间分辨率、病灶边界清晰度及结构对比度等参数;2.比较5T与3T MRI在前列腺癌靶向穿刺活检中的阳性检出率,包括总体癌检出率、临床显著性癌(csPCa)检出率及PIRADS评分与病理结果的一致性;3.分析两种系统在不同前列腺区域(如外周带、前部纤维肌肉带、移行区)病灶识别能力的差异;4.探索5T MRI是否可在不增加穿刺次数的前提下,提高穿刺靶点准确性及降低漏诊率;5. 为5T高场强磁共振在前列腺癌临床诊断中的推广应用提供科学依据和循证支持。通过上述比较,期望明确5T磁共振是否在前列腺癌诊断和靶向活检中优于传统3T MRI,从而为临床提供更精准的影像学指导,推动高场强MRI在泌尿肿瘤领域的临床转化与规范化应用。  

Objectives of Study:

This study compares the diagnostic value and clinical efficacy of 5T magnetic resonance imaging (MRI) and 3T MRI in MRI-guided targeted biopsy of prostate cancer, with specific objectives as follows: to evaluate the differences in image quality between the two MRI systems, including parameters such as signal-to-noise ratio (SNR), spatial resolution, clarity of lesion boundaries, and structural contrast; to compare the positive detection rates of 5T and 3T MRI in targeted biopsy of prostate cancer, including the overall cancer detection rate, clinically significant prostate cancer (csPCa) detection rate, and the consistency between PI-RADS scores and pathological results; to analyze the differences in the ability of the two systems to identify lesions in different prostate regions (such as the peripheral zone, anterior fibromuscular stroma, and transition zone); to explore whether 5T MRI can improve the accuracy of biopsy targets and reduce the missed diagnosis rate without increasing the number of punctures; and to provide scientific basis and evidence-based support for the promotion and application of 5T high-field MRI in the clinical diagnosis of prostate cancer. Through the above comparisons, it is expected to clarify whether 5T MRI is superior to traditional 3T MRI in the diagnosis and targeted biopsy of prostate cancer, so as to provide more accurate imaging guidance for clinical practice and promote the clinical transformation and standardized application of high-field MRI in the field of urological oncology.

随机方法(请说明由何人用什么方法产生随机序列):

本实验采用信封法进行分配隐藏,拟在单中心连续纳入满足纳入标准的患者。受试者将通过计算机随机数字表法随机分配至 3T MRI 组或 5T MRI 组,各组比例为 1:1。随机分组由独立研究协调员使用计算机随机数字表法预先生成,按照1:1比例分配至3T MRI组和5T MRI组。 ? 每个随机编号及对应分组信息被单独打印并密封在不透明、不可透光、顺序编号的信封中。每个信封外贴唯一编号,封口处加贴防拆封标识,确保在开启前无法识别组别。 ? 信封由与患者招募和评估无关的独立研究协调员统一保管,研究者在完成受试者筛选、签署知情同意书并确认符合纳入标准后,按照编号顺序依次启封分配信封,实施分组。 ? 分组信息对受试者保密,实现单盲设计;同时,信封开启过程由两人共同完成并记录,确保分配过程公开、透明、可追溯。

Randomization Procedure (please state who generates the random number sequence and by what method):

In this study, allocation concealment will be implemented using the envelope method, and consecutive patients meeting the inclusion criteria will be enrolled at a single center. Participants will be randomly assigned to either the 3T MRI group or the 5T MRI group at a 1:1 ratio via a computer-generated random number table. The randomization sequence will be pre-generated by an independent study coordinator using a computerized random number table, with participants allocated to the 3T MRI group and 5T MRI group at a 1:1 ratio. ? Each random number and its corresponding group assignment will be printed separately and sealed in opaque, light-proof, sequentially numbered envelopes. Each envelope will be labeled with a unique number, and a tamper-evident sticker will be affixed to the seal to ensure the group cannot be identified before opening. ? The envelopes will be centrally stored by an independent study coordinator who is not involved in patient recruitment or assessment. After screening participants, obtaining signed informed consent, and confirming they meet the inclusion criteria, the researcher will open the assignment envelopes in sequential order to carry out group allocation. ? Group assignment information will be kept confidential from participants, implementing a single-blind design. Meanwhile, the envelope-opening process will be completed and documented by two individuals to ensure the allocation process is open, transparent, and traceable.
