Role of New Functional MRI Techniques in the Diagnosis, Staging, and Followup of Gynecological Cancer: Comparison with PET-CT

Figure 4

Proven vaginal fornix recurrence after radical surgery for cervical cancer in a 65-year-old woman. First row (a1) axial T1-WI, (b1) DWI and (c1) PET-CT images show no remarkable alteration except for an abnormal signal at DWI in the right vaginal fornix (white arrow), with an abnormal ADC value, measuring 1.3 × 10−3 mm2/s. Second and Third rows: six months later (a2) axial T2-WI, (b2) DWI, (c2) PET-CT, and (d2) ADC map show that the ADC value in the right vaginal fornix had decreased to 1.1 × 10−3 mm2/s, corresponding to a hypermetabolic focus at PET-CT (white arrow). (e2) and (f2) DCE-MRI depicted a small focus with faster first-pass contrast agent enhancement, with a type III kinetic curve (washout type), which is indicative of malignancy.
