How Long Does A Pet Mri Take? A Comprehensive Guide

Is it possible to have both an MRI (Magnetic Resonance Imaging) and a PET (Positron Emission Tomography) scan performed on the same day? Yes, it is indeed feasible to undergo both of these diagnostic procedures simultaneously with the aid of modern PET/MRI machines. However, it is crucial to communicate specific factors with your healthcare provider beforehand to ensure a safe and accurate examination. If you have metal implants, medical devices, tattoos, experience claustrophobia, or suspect that you may be pregnant, it is imperative to inform your healthcare provider before scheduling the MRI, PET, or CT scan. This information is vital to tailor the procedure to your specific needs and circumstances, ensuring a successful and complication-free experience.

The process of a PET-MRI (Positron Emission Tomography-Magnetic Resonance Imaging) begins with the preparation phase. First, a trained radiographer places a small plastic tube known as a cannula into a vein in your hand or arm. Through this cannula, you will receive an injection of a specialized radioactive liquid called a radiotracer. The timing of this injection may vary depending on your specific medical situation. Typically, it is administered approximately an hour before the PET-MRI scan to allow the radiotracer to distribute throughout your body. However, in certain cases, such as emergencies or specific clinical scenarios, the PET-MRI scan may be performed immediately after the radiotracer injection. This combined imaging technique provides valuable insights into the structure and function of tissues and organs, aiding in the diagnosis and monitoring of various medical conditions.

Can PET MRI detect cancer? Yes, PET/MRI has shown promising results in cancer staging. Numerous studies have suggested that PET/MRI is not only feasible but also comparably accurate to PET/CT in most areas of the body. Specifically, when it comes to cancer detection in the head, neck, and pelvis, there is compelling evidence to suggest that PET/MRI may even outperform PET/CT. This information is based on research conducted as of July 21, 2015, and highlights the potential of PET/MRI as a valuable tool in the diagnosis and staging of cancer.
