This is a retrospective observational cohort study involving patients with suspected PPGLs who underwent 131I-MIBG scanning and surgical treatment between January 2020 and April 2023. The objective is to evaluate the correlation between MIBG imaging score and intraoperative hemodynamic fluctuations.

| Semiquantitative 131I-MIBG Scintigraphy Assessment | Other | Patients received thyroid blockade using solution of potassium iodide before the examination. After intravenous administration of 111 MBq of 131I-MIBG, whole body planar images were acquired at 24 hours (Day 1) and 48 hours (Day 2), respectively. |

| Difference of SBP ARV and MAP ARV in Different Groups | Mean arterial pressure (MAP) was calculated with the formula: MAP=1/3*SBP+2/3*DBP. ARV, which was defined as the average of absolute difference between successive BP values | Intraoperative systolic blood pressure (SBP) and diastolic blood pressure (DBP) were recorded automatically in a 5 min interval from the beginning to the end of surgery. |
