PET/CT Scans: The Game-Changer in Hodgkin Lymphoma Staging
Published: Aug 17, 2024
Positron Emission Tomography/Computed Tomography (PET/CT) has revolutionized how doctors stage and monitor classic Hodgkin lymphoma (cHL). Understanding this powerful imaging tool can help patients grasp their diagnosis and treatment journey better.
How PET/CT Works
PET/CT combines two imaging techniques. PET uses a radioactive sugar to highlight active cancer cells, while CT provides detailed anatomical images. Together, they create a comprehensive picture of where cancer is in the body and how active it is.
The Deauville Score
Doctors use a five-point scale called the Deauville score to interpret PET/CT results in cHL. This score compares the brightness of potential tumor sites to normal tissues like the liver. A higher score suggests more active disease, which can influence treatment decisions.
Beyond Initial Staging
PET/CT isn't just for initial diagnosis. It's also used to monitor treatment response and check for recurrence. This ability to track the cancer's activity over time helps doctors adjust treatment plans as needed, potentially improving outcomes.
Frequently Asked Questions
