What is the principle behind image fusion in radiology?

The principle behind image fusion in radiology is the combination of images obtained from multiple imaging modalities. This technique enhances the diagnostic information available to radiologists by integrating different types of data that could provide complementary insights into a patient's condition. For example, combining anatomical information from a CT scan with functional data from an MRI or PET scan allows for a more comprehensive view of a lesion, tumor, or other anatomical features.

By utilizing data from different modalities, image fusion improves the accuracy of diagnoses, aids in treatment planning, and enhances the overall understanding of complex medical conditions. This multifaceted approach leverages the strengths of each imaging technique while mitigating their individual limitations, ultimately leading to better patient outcomes and more informed clinical decisions.
