[Whole-body diffusion-weighted imaging in oncology: technical aspects and practical relevance]

Area of Science:

• Radiology
• Oncological Imaging
• Medical Imaging Techniques

Background:

• Whole-body diffusion-weighted imaging (WB-DWI) is emerging as a valuable tool in oncological imaging.
• It presents a radiation-free alternative to established methods like PET/CT.
• The method offers potential cost benefits over PET/CT examinations.

Purpose of the Study:

• To review the relevance and applications of WB-DWI in oncology.
• To present the technical aspects of performing WB-DWI.
• To discuss the current role of WB-DWI in cancer imaging based on practical oncological requirements.

Main Methods:

• Review of existing literature and clinical data on WB-DWI in cancer imaging.
• Analysis of technical considerations for WB-DWI acquisition and interpretation.
• Evaluation of WB-DWI's utility in meeting the practical demands of oncology.

Main Results:

• WB-DWI demonstrates significant relevance in oncological imaging.
• The technique provides a viable alternative to PET/CT, mitigating radiation exposure and reducing costs.
• Key technical aspects and current applications in cancer management are detailed.

Conclusions:

• WB-DWI is a relevant and promising imaging modality in oncology.
• Its advantages in terms of radiation safety and cost-effectiveness make it a compelling alternative to PET/CT.
• Further integration of WB-DWI into clinical practice is supported by its current role and technical feasibility.
