Bone marrow MR perfusion imaging and potential for tumor evaluation

Area of Science:

• Bone physiology
• Medical imaging
• Oncology

Background:

• Bone perfusion is crucial for assessing bone health and disease.
• Standard MRI provides anatomical information but limited functional data on bone perfusion.
• Assessing tumor activity and treatment response in bone requires advanced imaging techniques.

Purpose of the Study:

• To review the physiology of bone perfusion.
• To outline measurement techniques for bone perfusion using MRI.
• To highlight the potential of bone perfusion imaging in oncology.

Main Methods:

• Review of physiological principles of bone perfusion.
• Description of dynamic contrast-enhanced MRI (DCE-MRI) for bone perfusion assessment.
• Explanation of intravoxel incoherent imaging (IVIM) for bone perfusion analysis.

Main Results:

• Bone perfusion physiology can be elucidated through advanced MRI techniques.
• DCE-MRI and IVIM are viable methods for quantifying bone perfusion.
• Bone perfusion imaging shows promise in evaluating tumor burden and therapeutic efficacy.

Conclusions:

• Bone perfusion imaging offers a functional assessment of bone tissue.
• Advanced MRI techniques like DCE-MRI and IVIM enhance the evaluation of bone tumors.
• Perfusion parameters derived from MRI can serve as biomarkers for treatment response in bone pathologies.
