Diagnostic test for accuracy 

研究目的:

比较双参数MRI(bpMRI)、多参数MRI(mpMRI)、与深度学习(DL)辅助的双参数MRI(DL-bpMRI)在临床显著性前列腺癌(clinically significant prostate cancer, csPCa)病例中的诊断准确性,并探讨bpMRI与DL-bpMRI是否可以作为mpMRI的一种潜在替代方案。  

Objectives of Study:

To compare the diagnostic accuracy of biparametric MRI (bpMRI), multiparametric MRI (mpMRI), and deep learning (DL)-assisted biparametric MRI (DL-bpMRI) for clinically significant prostate cancer (csPCa), and to explore whether bpMRI and DL-bpMRI can serve as a potential alternative to mpMRI.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

? 男性、年龄≥18岁 ? 完成前列腺mpMRI(T2WI+DWI/ADC+DCE)扫描 ? 具备病理学结果或至少1年影像学随访

Inclusion criteria

1.Male, age>= 18 years. 2. Completion of prostate mpMRI (T2WI + DWI/ADC + DCE) scanning. 3.Availability of pathological results or at least 1 year of imaging follow-up.

排除标准:

? 图像扫描范围不完整,未完整覆盖前列腺 ? 图像质量无法满足诊断要求:严重伪影、噪声等 ? 既往前列腺活检、手术、放疗或系统性治疗 ? mpMRI与活检时间间隔大于3个月

Exclusion criteria:

1.Incomplete scan coverage of the prostate gland. 2.Unsuitable for diagnosis because of poor image quality, such as severe artifacts and noise. 3.History of prior prostate biopsy, surgery, radiotherapy, or systemic therapy. 4.Time interval between mpMRI and biopsy exceeding 3 months.

诊断试验:

Diagnostic Tests:

金标准或参考标准(即可准确诊断某疾病的单项方法或多项联合方法,在本研究中用于诊断是否有该病的临床参考标准):

优先依据组织学结果,包括前列腺穿刺活检(系统性穿刺联合靶向穿刺)或手术病理结果;对于无组织学证据的病例,则结合不少于1年的影像随访结果及临床资料进行综合判定。

Gold Standard or Reference Standard (The clinical reference standards required to establish the presence or absence of the target condition in the tested population in present study):

Based on histological results, including prostate biopsy (systematic biopsy combined with targeted biopsy) or surgical pathology findings; for cases without histological evidence, comprehensive assessment is conducted by integrating imaging follow-up results of at least one year with clinical data.

指标试验(即本研究的待评估诊断试验,无论为方法、生物标志物或设备,均请列出名称):

Index test:

Deep learning model

目标人群(可以是某种疾病患者或正常人群,详细描述其疾病特征,注意应纳入符合分布特点的全序列病例,具有良好的代表性)
