A Study of a Gadolinium-Based Contrast Agent (GBCA) for Adults Undergoing Magnetic Resonance Imaging (MRI) for Known or Highly Suspected Central Nervous System (CNS) Lesions
brief summary
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, HRS-9231 is non-inferior to Gadobutrol in lesion visualization scores and show 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 to explore the population pharmacokinetic characteristics of HRS-9231 in CNS MRI subjects.
