MRI stands for Magnetic Resonance Imaging, a scan that uses magnetic and radio waves to produce detailed morphological information of the organs, tissues and structures within the body.
PET stands for Positron Emission Tomography, imaging test that helps to measure the functionality of tissues and organs within the body.
PET-MR is a hybrid scanner that combines of the two modalities into a single scan. Capturing metabolic activity and anatomy together offers doctors a more precise and accurate assessment of disease, as well as an improved understanding of the physiologic process. This allows for easier and faster detection, characterization, staging and treatment of oncological, neurological and cardiovascular diseases, and exposes patients to lower levels of radiation.
PET-MRI is a high end technology product that inhabits high definition PET detectors in a 3 Tesla high magnetic field MRI resulting in most accurate imaging device for cancer diagnosis.
PET – MRI DIFFERENCE IN ONCOLOGICAL DIAGNOSIS
MRI is the closest diagnostic imaging method to pathomorphology due to its high tissue resolution and tissue specific imaging techniquies.
When MRI Spectroscopy, Diffusion-weighted MR İmaging, Perfusion and BOLD (Detection of Tumor Hypoxia) examinations are added, functional data is obtained resulting in higher diagnostic sensitivity.
The key advantage of PET-MRI fort he patient is the lack of radiation during MR imaging.
Specificity increases in tumor – specific PET agents, making use of molecular imaging providing metabolic, functional and numeric information in oncological diagnosis in conjuction with multi-paramtric MRI techniques.
