PET/CT and MRI in Bladder Cancer

Area of Science:

• Urology
• Oncology
• Radiology

Background:

• Bladder cancer (BCa) is a common urinary tract malignancy.
• Accurate preoperative staging is crucial for BCa treatment decisions.
• Standard imaging techniques like CT and MRI have improved BCa visualization.

Purpose of the Study:

• To review recent advancements in PET/CT and MRI for bladder cancer staging.
• To highlight improvements in detecting metastatic disease and primary lesions.
• To discuss the evolving role of multi-parametric MRI in BCa staging.

Main Methods:

• Review of recent literature on PET/CT and MRI in bladder cancer.
• Focus on techniques for preoperative staging and metastatic disease detection.
• Exploration of novel PET tracers and functional MRI techniques.

Main Results:

• ¹⁸F-FDG PET/CT is valuable for detecting metastatic bladder cancer.
• Detecting primary bladder wall lesions with ¹⁸F-FDG PET/CT requires further investigation.
• Diffusion-weighted MRI and multi-parametric MRI show promise for improved lesion detection and staging.

Conclusions:

• Advanced imaging, including PET/CT and MRI, significantly improves bladder cancer staging.
• Continued research into novel PET tracers and functional MRI techniques is essential.
• These imaging modalities are vital for accurate preoperative assessment and therapeutic decision-making in BCa.
