cells because they use sugar more quickly. PET/CT

may be done with one or two machines depending on

the cancer center.

Neck CT and head CT or MRI

It may be useful to get an imaging test of your neck

and head. CT can be used to image your neck. Either

CT or MRI (

used to image your head. MRI is an imaging test

that uses a magnetic field and radio waves to make

pictures. A device will be placed around your neck

and head that sends and receives radio waves. You

may also be given a contrast dye to make the pictures

clearer.

Biopsy

Bone marrow biopsy

At times, peripheral T-cell lymphoma has spread

to bone marrow before treatment is started. Thus,

a bone marrow biopsy is needed before treatment

to confirm if there’s cancer. A bone marrow biopsy

removes a sample of bone and soft bone marrow.

Often, this test is done at the same time on the back

of hip bone. You may receive a light sedative before

the test. You will likely lie on your side as shown in

Figure 2.2

. Your doctor will clean your skin and then

give local anesthesia to numb the site. Once numb, a

wide needle will be inserted into the bone and rotated

to remove bone and soft marrow. This biopsy may

cause bone pain and can bruise your skin for a few

days. The samples will be sent to a lab for testing.
