Advancements in hybrid imaging techniques: Enhancing diagnostic accuracy with PET/MRI and PET/CT
Keywords:
Medical Diagnostics, Oncology, Hybrid Imaging, PET/MRI, PET/CTAbstract
Background Hybrid imaging techniques, including PET/MRI and PET/CT, are transforming medical diagnostics by integrating metabolic data from Positron Emission Tomography (PET) with the detailed anatomical resolution provided by Magnetic Resonance Imaging (MRI) or Computed Tomography (CT). This integration improves diagnostic accuracy, especially in oncology, where accurate tumor localization and characterization are essential for effective treatment planning. PET/CT is commonly utilized; however, PET/MRI presents benefits including enhanced soft tissue contrast and decreased radiation exposure, rendering it especially beneficial for pediatric patients or individuals needing multiple scans. Challenges persist in standardization, accessibility, and addressing the inherent physical limitations associated with the integration of these distinct imaging modalities. Aim This review seeks to evaluate the current status of hybrid imaging, specifically PET/MRI and PET/CT, by analyzing their diagnostic efficacy, integration challenges, and prospective developments. The review analyzed the benefits and drawbacks of each technique, compared their clinical applications, and investigated emerging hybrid modalities. Methods A thorough literature review was performed, including studies and articles on the applications of PET/MRI and PET/CT in diverse disease areas. The review examined current studies on diagnostic accuracy, technical integration challenges, and prospective developments in hybrid imaging technology.
