HRS-9231

The purpose of this study is to evaluate the efficacy and safety of HRS-9231 for Central Nervous System (CNS) Magnetic Resonance Imaging (MRI); to demonstrate that, in patients requiring CNS MRI examinations, contrast-enhanced MRI with HRS-9231 is superior to unenhanced MRI in lesion visualization scores using the patients as their own controls and show that, in patients requiring CNS MRI examinations, HRS-9231 is non-inferior to Gadobutrol in lesion visualization scores; and to explore the population pharmacokinetic characteristics of HRS-9231 in CNS MRI subjects.

评价HRS-9231用于身体部位（中枢神经系统除外）磁共振成像（MRI）的有效性。证明HRS-9231用于身体部位MRI的有效性不劣于钆布醇。评价HRS-9231用于身体部位 MRI的安全性。探索HRS-9231用于身体部位MRI受试者的群体药代动力学特征。
