*3.1. Patient Cohort*

In total, 251 LN from 63 patients were assessed histologically and quantified multiparametrically with [18F]FDG PET/MRI. A total of 211 of 251 LN were located within the FOV of the delayed scan, enabling dual-time-point [18F]FDG kinetic calculation. A total of 219 of 251 LN had a sufficient size for ADC calculation. A total of 79 of 251 LN from 54 of 63 patients met the criteria for SLN in [99mTc]Tc-Nanocolloide SPECT/CT. Detailed patient characteristics are presented in Table 1.



\* One outlier with 89 d but no LNM at histology.

#### *3.2. Prevalence of LNM Dependent on Stage and Grade of Primary Tumors*

In 2 patients and 6 LN, respectively, no grading of the primary tumor was reported owing to conizations performed at other centers and no tumor was left when performing the (radical) hysterectomy in our center. The prevalence of LNM increased with the T-stage of the primary tumor (Figure 1). The patient-based prevalence of LNM was not significantly higher in patients with G3 (40%) than G2 (29.6%) tumors (*p* = 0.35). No LNM occurred in patients with G1 tumors.
