Motivation: For the preoperative assessment of rectal cancer microcirculation use DCE ang IVIM.
Goal(s): To analyze the correlation between rectal cancer microvascular density, as indicated by CD34 immunohistochemistry, and quantitative parameters obtained from DCE and IVIM MRI.
Approach: Assess the correlation between quantitative imaging parameters from DCE and IVIM, and microvascular density.
Results: Significant differences in Ktrans and D values among different degrees of rectal cancer differentiation; furthermore, Ktrans, Kep, and D* values exhibited significant correlations with rectal cancer microvascular density, while Ve, D, and f did not show significant correlations.
Impact: The validation of the utility of non-invasive MRI techniques, particularly DCE and IVIM, assesses rectal cancer microcirculation, which can enhance early diagnosis and treatment planning for patients, ultimately improving the prognosis and management of rectal cancer.
