PET CT Scan Report

PET CT report is a radioactive tracer used in oncology, cardiology, and neurology help doctors to analyse the signs of cancer, heart disease and brain disorders. PET CT scan is a hybrid imaging method used to observe the metabolic and anatomical changes in the body. It utilizes PET (Positron Emission Tomography) and CT (Computed Tomography) for this purpose. A PET CT report encompasses the findings from this test along with the final diagnosis and recommendation. It is used to guide further medical intervention. Find the CT report type as given below;

Procedure Involved

Patient Information Collection

When a patient arrives with a complaint, they are attended to by the consulting physician.

The physician records all the relevant clinical data, such as signs and symptoms, duration of the symptoms, past medical history, past or ongoing medications, etc.

Selection of an imaging modality

Based on the clinical information and the level of urgency, a suitable radiological imaging technique is selected. (In this case, it would be PET CT)

Performing the PET CT

The PET CT scan is performed by a radiology technician present at the healthcare institution.

To perform this test, a small amount of radioactive tracer is injected into the veins.

This tracer travels to the different tissues of the body, especially accumulating in the abnormal tissues in the body.

These tracers are detected by a PET scanner, which maps out the tracer location in the body.

Based on this information, a CT scan is performed based on the anatomical information extracted from the PET scan

Finally, the metabolic and anatomic visuals are mapped on a single image (image fusion)

Image review by a radiologist

After the images are obtained, they are then analyzed by a licensed radiologist.

The radiologist correlated the patient’s clinical information with the image findings to form a meaningful conclusion.

After the image review is complete, the radiologist prepares a diagnostic report encompassing all the findings from the PET CT scan.

This report is signed by the radiologist and is then sent to the physician for further medical intervention.

Conditions to Diagnosed

Common Conditions Diagnosed on PET-CT Scan report:

Cancer (Oncology)

PET-CT scans are most commonly used for:

Detecting cancer: PET scans can highlight abnormal metabolic activity, which is often seen in cancer cells, making it effective for early detection.

Staging cancer: Helps to determine the extent (stage) of cancer, such as whether it has spread to other organs.

Monitoring treatment response: Evaluating how well cancer treatments (like chemotherapy or radiation therapy) are working.

Detecting recurrence: PET-CT can identify if cancer has returned after treatment.

Common Cancers Diagnosed with PET-CT:

Lung cancer

Colon cancer

Lymphomas

Breast cancer

Head and neck cancers

Melanoma

Ovarian cancer

Cardiac Conditions (Cardiology)

PET-CT scans are used to assess heart health, particularly:

Coronary artery disease: Evaluates blood flow to the heart and can identify areas of reduced or absent blood flow due to blockages.

Cardiac viability: Helps to assess if heart muscle is still viable (alive) after a heart attack and can guide treatment decisions for heart failure.

Heart function: Assesses the heart’s ability to pump blood.

Neurological Disorders

PET-CT scans are helpful for diagnosing and monitoring neurological conditions, such as:

Alzheimer’s disease: Detects changes in brain metabolism, helping in early diagnosis before significant symptoms appear.

Epilepsy: Helps localize areas of the brain where seizures originate, aiding in treatment planning.

Parkinson's disease: Evaluates changes in brain function related to Parkinson’s.

Brain tumors: Can identify the location and activity of brain tumors.

Multiple sclerosis (MS): Assesses the progression of MS by observing changes in brain activity.

Infections and Inflammation

Infections: Helps to locate active infection sites, such as in cases of abscesses or sepsis, especially in bones and organs.

Inflammatory diseases: Can help assess inflammatory conditions, like rheumatoid arthritis or Crohn’s disease, by detecting areas of high metabolic activity.

Evaluation of Unexplained Symptoms

Fever of unknown origin: If the cause of fever is unclear, a PET-CT can sometimes help in identifying underlying infections, cancers, or inflammatory conditions.

How PET-CT Works

The PET scan detects radioactive tracers injected into the body, which are absorbed by cells. Cancers, infections, and other diseases often absorb these tracers more than healthy cells, making them visible on the PET scan.

The CT scan provides detailed anatomical images that help locate exactly where the problem is in the body.

Frequently Asked Questions (FAQs):

Q. What is the main goal of a PET CT scan?

PET CT scan visualizes the anatomical and metabolic activities in specific tissues of the body.

Q. Why are different tracers used in PET CT scans?

The different tracers are meant to target different biological processes (e.g., glucose uptake) in the tissues.

Q. What does fusion imaging mean in PET CT?

In PET CT, fusion imaging refers to combining the visual data from PET with a CT scan.

Q. Can PET CT detect diseases at an early stage?

Yes. PET CT can detect the metabolic changes occurring due to the disease before any physical symptoms occur.

Q. Can PET CT grade the response to the treatment?

Yes. A PET CT scan can also evaluate the response to the treatment based on recovered metabolism, reduction in abnormal organ size, and other similar parameters.
