Key result
Non-contrast-enhanced 3D fresh blood imaging MR angiography clearly depicted major arteries and significantly differentiated vascularity between benign and malignant soft tissue tumors (p=0.007).
Why the study?
Can 3D fresh blood imaging (FBI) MR angiography without contrast enhancement depict vascularity and differentiate between benign and malignant musculoskeletal tumors?
Population
57 patients with bone or soft tissue tumors, average age 39.8 years, 32 males and 25 females.

Can 3D fresh blood imaging (FBI) MR angiography without contrast enhancement depict vascularity and differentiate between benign and malignant musculoskeletal tumors?
p-value: p=0.007
Non-contrast-enhanced 3D fresh blood imaging MR angiography can clearly depict major arteries in musculoskeletal tumors and differentiate between benign and malignant soft tissue tumors.
Doi et al. (2006) conducted a cross-sectional in Bone and soft tissue tumors (n=57). 3D fresh blood imaging (FBI) MR angiography was evaluated on Difference in signal-to-noise ratio (SNR) of vascularity between benign and malignant soft tissue tumors (p=0.007). Non-contrast-enhanced 3D fresh blood imaging MR angiography clearly depicted major arteries and significantly differentiated vascularity between benign and malignant soft tissue tumors (p=0.007).
