What is PET-MR?

PET-MR is an integrated fusion system combining Positron Emission Tomography (PET) and Magnetic Resonance Imaging (MR). It enables the simultaneous acquisition of functional metabolic information and high-resolution anatomical images, achieving a truly unified spatiotemporal scan.

Key Technological Highlights of the 4th Generation V4.0

COMPASS Technology — Intelligent positioning and navigation to enhance scanning precision and efficiency

Ultra-Low Radiation Dose — Reduces radiation exposure by over 60% compared to PET/CT, making it particularly suitable for children, women of childbearing age, and patients requiring multiple follow-up examinations

High Soft-Tissue Resolution — Utilizes multi-parametric, multi-sequence MR imaging to clearly delineate the boundaries between tumors and normal tissues

Multi-Modal Biological Target Delineation — Enables image fusion of results, providing "GPS-like navigation" for precision radiotherapy planning

Ultra-Large Field of View & Rapid Scanning — Makes whole-body examinations more efficient and ensures a more comfortable experience for patients

Clinical Application Advantages

Precision Oncology: Early diagnosis, staging, and treatment efficacy assessment for soft-tissue tumors—including brain tumors, head and neck cancers, prostate cancer, gynecological tumors, lymphomas, and breast cancer

Neurological Disorders: Diagnosis and assessment of Alzheimer's disease, Parkinson's disease, localization of epileptic foci, and evaluation of brain function

Cardiovascular System: Assessment of myocardial viability, as well as analysis of ventricular structure and function

Pediatrics & Special Populations: Its ultra-low radiation characteristics make tumor screening safer for children
