Can a PET scan show cancer in bones?
PET scans can help show the spread of bone cancer to the lungs, other bones, or other parts of the body. They can also be used to see how well the cancer is responding to treatment. Many machines can do a PET and CT scan at the same time (PET/CT scan).
Which is better PET scan or bone scan?
Bone positron emission tomography (PET) was significantly more accurate than bone scan in patient (p = 0.0306) and lesion (p = 0.0001) based analyses.
What does metastatic cancer look like on a bone scan?
Why might I need a bone scan? Bone scans are used primarily to detect the spread of metastatic cancer. Because cancer cells multiply rapidly, they will appear as a hot spot on a bone scan. This is due to the increased bone metabolism and bone repair in the area of the cancer cells.
How do you confirm bone Mets?
Bone metastasis can be diagnosed using laboratory tests, radiographic examinations, CAT scans, MRI and biopsy
- Laboratory Tests.
- Radiographic Examination.
- Computerized Axial Tomography (CAT.
- Magnetic Resonance Imaging (MRI)
- Bone Marrow Aspiration and Biopsy.
What is the best scan to detect bone cancer?
CT scan. CT scans are usually used to help form an initial bone cancer diagnosis and to see whether the cancer has spread to other areas of the body. CT scans may also be used to guide the biopsy needle.
How long can you live when cancer spreads to bones?
Most patients with metastatic bone disease survive for 6-48 months. In general, patients with breast and prostate carcinoma live longer than those with lung carcinoma.
Why do I need a bone scan instead of a PET scan?
Conclusions The difference between bone scan and PET/CT for detection of bone metastases may be attributable to the different mechanism. Bone scan depends on the osteoblastic response to bone destruction by tumor cells,and FDG-PET/CT detects the metabolic activity of the tumor cells.
How long does a full body PET scan last?
The entire PET scan process takes about two hours. It can take up to 60 minutes for your body to absorb the injected radiotracer. During this time, you’ll need to sit quietly and limit your movements. The actual PET scan takes about 45 minutes.

Most patients with metastatic bone disease survive for 6-48 months. In general, patients with breast and prostate carcinoma live longer than those with lung carcinoma. Patients with renal cell or thyroid carcinoma have a variable life expectancy.
