Abstract Objective To compare the sensitivity and specificity of combined intravaginal and vaginal coil T2WI and T2WI and DWI in the diagnosis and staging of small cervical neoplasms. Methods Thirty-eight patients with stage Ⅰa / Ⅰ 1b cervical cancer were prospectively optimized for 3.0 T MRI of intravaginal and vaginal coils. Histopathology as a reference, the tumor and paracancerous tissue infiltration diagnosis of sensitivity and specificity by a radiologist to read the coronal T2WI or T2WI and DWI
