How do diagnose Lymphoma?
Computed Tomography (CT):
CT is the most common method to diagnose and stage lymphoma. CT can detect any enlarged lymph nodes deep within the body and can measure their size very accurately. CT is often used to guide the biopsy of enlarged nodes that are found deeper in the body.
In patients with enlarged lymph nodes that can be felt on physical examination, ultrasound is usually performed first. Ultrasound. detection of these nodes is usually very accurate. Ultrasound.is also fairly accurate to suggest if a node is abnormal and may be involved with a tumor. Ultrasound. can be used to guide needles to biopsy the enlarged nodes as well.
Positron Emission Tomography(PET)/CT:
PET/CT is an extremely sensitive method used to stage lymphoma and is particularly useful in identifying the effects of treatment. Small sites of disease not detected accurately with CT alone may be seen on a PET/CT scan.
