PET-CT for Lymphoma Diagnosis and Monitoring
Lymphoma is a cancer of the lymphatic system — a network of lymph nodes, vessels, and organs that help fight infections. Because lymphoma can affect multiple areas of the body, accurate whole-body imaging is essential for proper diagnosis and treatment planning.
One of the most effective imaging tools for this purpose is the PET-CT scan.
At Molecular Diagnostics & Therapy, advanced PET-CT technology is used to help doctors diagnose, stage, and monitor lymphoma with high precision for patients across Delhi-NCR and surrounding regions.
Understanding Lymphoma
Lymphoma is mainly classified into:
Hodgkin Lymphoma
Non-Hodgkin Lymphoma
Common symptoms may include:
Swollen lymph nodes (neck, armpit, groin)
Persistent fever
Night sweats
Unexplained weight loss
Fatigue
Since lymphoma can spread through the lymphatic system to other organs, early detection and detailed imaging are crucial.
Why PET-CT Is Important in Lymphoma
A PET-CT scan combines:
PET (Positron Emission Tomography) – Detects metabolic activity of cancer cells.
CT (Computed Tomography) – Provides detailed structural images.
Lymphoma cells are highly active metabolically. The PET component detects this activity, while the CT scan shows the exact anatomical location. Together, they provide a comprehensive picture of the disease.
1️⃣ PET-CT for Initial Diagnosis
When lymphoma is suspected, PET-CT can:
Identify affected lymph nodes
Detect involvement of organs like spleen, liver, or bone marrow
Help guide biopsy by targeting the most active area
This improves diagnostic accuracy and helps confirm the extent of the disease.
2️⃣ PET-CT for Staging
Staging determines how far lymphoma has spread. PET-CT is considered one of the most reliable tools for staging because it:
Scans the entire body in one session
Detects even small areas of active disease
Helps determine the correct stage (I to IV)
Accurate staging allows oncologists to create the most effective treatment plan.
3️⃣ Monitoring Treatment Response
During chemotherapy or immunotherapy, doctors may recommend follow-up PET-CT scans to:
Assess how well treatment is working
Detect residual disease
Modify treatment if necessary
Since PET imaging measures metabolic activity, it can show response to therapy earlier than structural imaging alone.
4️⃣ Detecting Recurrence
Even after successful treatment, regular monitoring is important. PET-CT helps in:
Detecting early signs of relapse
Identifying new areas of involvement
Supporting timely medical intervention
Early detection of recurrence improves treatment outcomes.
What to Expect During the Procedure
The PET-CT process usually includes:
Injection of a small amount of radioactive tracer (FDG).
A resting period of about 45–60 minutes.
A painless scan lasting 20–30 minutes.
The tracer naturally exits the body within a day or two.
At Molecular Diagnostics & Therapy, patients receive detailed pre-scan instructions to ensure accurate results and a comfortable experience.
Is PET-CT Safe?
Yes. PET-CT scans are widely used in oncology and follow strict safety protocols. The radiation exposure is medically controlled and justified based on clinical need. The diagnostic benefits in lymphoma care far outweigh minimal risks.
