UCSF Radiology: Fusing CT and PET Images for Diagnostic Imaging

Best Answer

PET scan: A PET scan, which uses a small amount of radioactive material, can help show if an enlarged lymph node is cancerous and detect cancer cells throughout the body that may not be seen on a CT scan.

Ultrasound is also used to image the abdominal organs and kidneys, which may be affected by enlarged lymph nodes.

PET stands for positron emission tomography. This type of scan can show how body tissues are working, as well as what they look like. It's used to help diagnose some conditions including cancer. PET scans are often combined with CT scans to produce more detailed images.

Can ultrasound show cancer in lymph nodes?

A lymph node ultrasound and biopsy is a way of checking the lymph nodes under the arm after breast cancer is diagnosed. Sometimes the cancer cells can spread into the nearby lymph nodes. Ultrasound scans use high frequency sound waves to create a picture of a part of the body. This turns the sound waves into a picture.

Can a PET scan detect cancer?

Is cancer in lymph nodes terminal?

There are several types of lymphomas, such as non-Hodgkin lymphoma. Cancer cells can also spread to the lymph nodes from a cancer in any part of the body. This is called metastatic cancer. Cancer cells break off from a tumor in the body and travel to an area of lymph nodes.

How does a PET scan detect cancer?

A PET scan uses a radioactive drug (tracer) to show this activity. This scan can sometimes detect disease before it shows up on other imaging tests. A PET scan is useful in revealing or evaluating several conditions, including many cancers, heart disease and brain disorders.

Can PET scan detect all cancers?

The PET scan uses a mildly radioactive drug to show up areas of your body where cells are more active than normal. It's used to help diagnose some conditions including cancer. It can also help to find out where and whether cancer has spread. These are called PET-CT scans.

Do cancerous lymph nodes shrink?

Usually, they're alerting you to a mild infection or illness. Once your immune system has fought the pesky invader, your lymph nodes will shrink back to their normal size. Occasionally, though, swollen lymph nodes can indicate a more serious condition such as cancer.

Does lymph node cancer hurt?

Some cancers cause swelling of the lymph nodes. Cancer may start in the lymph nodes, or more commonly, it may spread there from somewhere else in the body. Pain or swelling in the lymph nodes is a common symptom of cancer that starts in the lymphatic system, such as non-Hodgkin lymphoma and Hodgkin lymphoma.

Can a bone scan detect cancer?

Your doctor may order a bone scan if you have unexplained skeletal pain, a bone infection or a bone injury that can't be seen on a standard X-ray. A bone scan can also be an important tool for detecting cancer that has spread (metastasized) to the bone from the tumor's original location, such as the breast or prostate.

Can a CT scan detect cancer?

CT scans can show a tumor's shape, size, and location. They can even show the blood vessels that feed the tumor – all without having to cut into the patient. By comparing CT scans done over time, doctors can see how a tumor is responding to treatment or find out if the cancer has come back after treatment.

Can a CT scan detect cancer in the abdomen?

A CT scan uses x-rays to make detailed, cross-sectional images of your body. CT scans show the stomach fairly clearly and often can confirm the location of the cancer. CT scans can also show the organs near the stomach, such as the liver, as well as lymph nodes and distant organs where cancer might have spread.

CT scans can show a tumor's shape, size, and location. They can even show the blood vessels that feed the tumor – all without having to cut into the patient. By comparing CT scans done over time, doctors can see how a tumor is responding to treatment or find out if the cancer has come back after treatment.

Can a bone density scan detect cancer?

This scan also may help detect whether cancer has metastasized, or spread, to the bones. Using low levels of X-rays to measure bone mineral density, the DEXA scan examines the entire skeleton or specific points on the body, such as the spine or hip. This score is used to determine your risk of breaking a bone.

MRI creates pictures of soft tissue parts of the body that are sometimes hard to see using other imaging tests. MRI is very good at finding and pinpointing some cancers. An MRI with contrast dye is the best way to see brain and spinal cord tumors. Using MRI, doctors can sometimes tell if a tumor is or isn't cancer.

Do swollen lymph nodes mean cancer?

Often, swollen lymph nodes will be close to where the problem is. When you have strep throat, lymph nodes in your neck may swell. When several areas of lymph nodes are swollen, that suggests the problem is throughout your body. It could be something like chickenpox, HIV, or a cancer such as leukemia or lymphoma.

How does a PET scan work to detect cancer?

A positron emission tomography (PET) scan is an imaging test that helps reveal how your tissues and organs are functioning. A PET scan uses a radioactive drug (tracer) to show this activity. This scan can sometimes detect disease before it shows up on other imaging tests.

If your doctor thinks your swollen lymph nodes could be cancer, tests and imaging can confirm the diagnosis or point to something else. Based on where the cancer might be, you could get a chest X-ray, an ultrasound, a CT scan, or an MRI.

Are cancerous lymph nodes hard or soft?

These characteristics can be useful in suggesting the cause of the lymph node swelling. For example, a hard, nontender, non-moveable lymph node may be more characteristic of a cancer spread to that node. On the other hand, a soft, tender, moveable lymph node could more likely represent an infection.
