摘要

Objectives

The Scrotal and Penile Imaging Working Group (SPIWG) of the European Society of Urogenital Radiology (ESUR) aimed to formulate recommendations on the imaging modalities and minimal technical requirements for abdominopelvic imaging in the follow-up of adult patients treated for testicular germ-cell tumors (TGCT).

Methods

The SPIWG members performed an extensive literature search, reviewed the current clinical practice, and reached a consensus based on the opinions of experts in the field.

Results

Recurrence in patients treated for TGCT mainly occurs in retroperitoneal lymph nodes (LNs). Abdominopelvic CT and MRI are equivalent assessing retroperitoneal LNs. MRI has the advantage of avoiding radiation exposure, and moreover, diffusion-weighted images (DWI) may increase the detection rates without the need for contrast administration. In patients treated for stage I TGCT, the ESUR-SPIWG recommends MRI over CT for the detection of retroperitoneal LNs during the follow-up after treatment. CT, however, remains the follow-up imaging of choice in patients with advanced disease. When MRI is used, the recommended minimal requirements are at least one high-quality anatomical sequence (T1-WI or T2-WI) in axial and coronal planes, and DWI in the same axial plane, ≤ 4 mm contiguous slices from the diaphragm to the perineum. When CT is used, the recommended minimal requirement is a standard-dose contrast-enhanced CT in the portal-venous phase, scanned from the diaphragm to the perineum.

Conclusions

In this paper, the ESUR-SPIWG provides recommendations on the imaging modalities and minimal technical requirements for abdominopelvic imaging in the follow-up of adult patients treated for TGCT.

Key Points

Question There are no recommendations on the preferred imaging modality or scan sequences required for abdominopelvic imaging in the follow-up after treatment for testicular cancers.

Findings The European Society of Urogenital Radiology Scrotal and Penile Imaging Working Group (ESUR-SPIWG) provides recommendations for abdominopelvic imaging in follow-up after treatment for testicular cancers.

Clinical relevance Recurrence of testicular germ-cell tumors mainly occurs in retroperitoneal lymph nodes. Both CT and MRI provide similar morphological assessments, but radiation exposure can be avoided by using MRI instead of CT.
