Abstract

Objective: To assess the effectiveness of diffusion-weighted magnetic resonance imaging (DW-MRI) in the detection of non-palpable undescended testis (NPUT) and to compare DW-MRI results with surgical findings.

Methods: This descriptive, cross-sectional study was carried out at Dow Institute of Radiology, Dow University of Health Sciences. Karachi on a cohort of patients who underwent DW-MRI for suspected NPUT between 15th September, 2022 to 16th March, 2023. The study included 175 boys below the age of 16 years with history of clinically non-palpable testes. MRI scans were acquired using additional DWI sequence. Two radiology faculty of more than five years of experience independently evaluated the DW-MRI images for the presence or absence of testes in its normal anatomical position, abnormal location, side and size of testes.

Results: Out of the 175 patients, DW-MRI successfully detected 128 (73.1%) non-palpable undescended testes. Statistical analysis in clinically detected cases of showed sensitivity of NPTU 0.8%, specificity of 92.5%, diagnostic accuracy 94.29%, positive predictive value 97.7%, and negative predictive value 84.1% for localizing undescended testes with Diffusion Weighted DW-MRI taking surgical findings as gold standard.

Conclusion: DWI sequences complement the conventional MRI, increasing its sensitivity and diagnostic accuracy. By facilitating early and accurate diagnosis, DW-MRI has the potential to streamline patient management, reduce unnecessary surgical exploration, and ultimately improve the long-term reproductive health and quality of life for individuals with undescended testes.

弥散加权磁共振成像在检测无法扪及的未降睾丸方面的实用性。
目的评估弥散加权磁共振成像(DW-MRI)在检测非扪及性睾丸下降(NPUT)中的有效性,并将 DW-MRI 结果与手术结果进行比较:这项描述性横断面研究在卡拉奇陶氏健康科学大学陶氏放射研究所进行。这项描述性横断面研究是在卡拉奇陶氏健康科学大学陶氏放射研究所进行的,研究对象是 2022 年 9 月 15 日至 2023 年 3 月 16 日期间接受 DW-MRI 检查的疑似 NPUT 患者。研究对象包括 175 名年龄在 16 岁以下、临床上睾丸无法触及的男孩。磁共振成像扫描采用附加的 DWI 序列。由两名具有五年以上经验的放射科教师独立评估 DW-MRI 图像,以确定睾丸的正常解剖位置、异常位置、侧位和大小:结果:在 175 名患者中,DW-MRI 成功检测出 128 个(73.1%)无法扪及的未降睾丸。对临床检测病例的统计分析显示,以手术结果为金标准,弥散加权 DW-MRI 对未扪及睾丸的定位敏感性为 0.8%,特异性为 92.5%,诊断准确性为 94.29%,阳性预测值为 97.7%,阴性预测值为 84.1%:结论:弥散加权 DWI 序列是对传统磁共振成像的补充,提高了其灵敏度和诊断准确性。通过促进早期准确诊断,DW-MRI 有可能简化患者管理,减少不必要的手术探查,并最终改善睾丸下降患者的长期生殖健康和生活质量。

期刊介绍: It is a peer reviewed medical journal published regularly since 1984. It was previously known as quarterly "SPECIALIST" till December 31st 1999. It publishes original research articles, review articles, current practices, short communications & case reports. It attracts manuscripts not only from within Pakistan but also from over fifty countries from abroad. Copies of PJMS are sent to all the import medical libraries all over Pakistan and overseas particularly in South East Asia and Asia Pacific besides WHO EMRO Region countries. Eminent members of the medical profession at home and abroad regularly contribute their write-ups, manuscripts in our publications. We pursue an independent editorial policy, which allows an opportunity to the healthcare professionals to express their views without any fear or favour. That is why many opinion makers among the medical and pharmaceutical profession use this publication to communicate their viewpoint.
