Abstract
Objective: To assess the value of dYnamic Contrast Enhanced MRI (DCE-MRI) versus conventional MR imaging and Diffusion Weighted Imaging (DWI) in the staging of cervical malignancies.
Methodology: Fifty cases of proved cancer cervix prior staging subjected to dynamic post contrast technique: One pre-and four post contrast phases. DWI was scanned using different p-values and ADC values were measured.
Results: DWI was the most accurate in staging operable cases (91%) and is the modality of choice for assessment of locally advanced carcinomas. Regarding detection of parame-trial infiltration, DCE-MRI was less specific than DWI (88.6% versus 91.9%) yet more specific than T2WIs (88.6% versus 86.5%). In metastatic lymph nodes, DCE-MR showed the least accuracy of 86%.
Conclusion: DCE-MR can delineate local tumors and exclude bladder/rectal invasion. DWI is helpful in evaluate the local and distant extent of cervical malignancies.
