2. Positron emission tomography - Wikipedia

   en.wikipedia.org/wiki/Positron_emission_tomography

   Whole-body PET scan using 18 F-FDG (fluorodeoxyglucose). The normal brain and kidneys are labeled, and radioactive urine from breakdown of the FDG is seen in the bladder. In addition, a large metastatic tumor mass from colon cancer is seen in the liver. PET scanning with the radiotracer [18 F]fluorodeoxyglucose (FDG) is widely used in clinical ...

3. Bone metastasis - Wikipedia

   en.wikipedia.org/wiki/Bone_metastasis

   Oncology. Bone metastasis, or osseous metastatic disease, is a category of cancer metastases that result from primary tumor invasions into bones. Bone-originating primary tumors such as osteosarcoma, chondrosarcoma, and Ewing sarcoma are rare; the most common bone tumor is a metastasis. [1] Bone metastases can be classified as osteolytic ...

4. PET-CT - Wikipedia

   en.wikipedia.org/wiki/PET-CT

   OPS-301 code. 3-75. Positron emission tomography–computed tomography (better known as PET-CT or PET/CT) is a nuclear medicine technique which combines, in a single gantry, a positron emission tomography (PET) scanner and an x-ray computed tomography (CT) scanner, to acquire sequential images from both devices in the same session, which are ...

5. Cancer of unknown primary origin - Wikipedia

   en.wikipedia.org/wiki/Cancer_of_unknown_primary...

   Specialty. Oncology. Cancer of unknown primary origin (CUP) is a cancer that is determined to be at the metastatic stage at the time of diagnosis, but a primary tumor cannot be identified. A diagnosis of CUP requires a clinical picture consistent with metastatic disease and one or more biopsy results inconsistent with a tumor cancer.

6. Lung cancer staging - Wikipedia

   en.wikipedia.org/wiki/Lung_cancer_staging

   The mainstay of non-invasive staging is a CT scan of the chest followed by metabolic imaging with a PET scan. The CT scan shows abnormalities such as a lung nodule or enlarged lymph nodes whereas the PET scan reveals increased metabolism such as occurs in structures which contain rapidly growing cancer cells. PET/CT combined the benefits of ...

   en.wikipedia.org/wiki/Piflufolastat_F-18

   [4] [7] In the first trial, a cohort of 268 participants with biopsy-proven prostate cancer underwent PET/CT scans performed with piflufolastat F-18. [4] These participants were candidates for surgical removal of the prostate gland and pelvic lymph nodes and were considered at higher risk for metastasis. [4]

8. PET response criteria in solid tumors - Wikipedia

   en.wikipedia.org/wiki/PET_response_criteria_in...

   PET response criteria in solid tumors. PET response criteria in solid tumors (PERCIST) is a set of rules that define when tumors in cancer patients improve ("respond"), stay the same ("stabilize"), or worsen ("progress") during treatment, using positron emission tomography (PET). The criteria were published in May 2009 in the Journal of Nuclear ...

9. Cancer staging - Wikipedia

   en.wikipedia.org/wiki/Cancer_staging

   For example, in the cases of breast cancer and prostate cancer, doctors routinely can identify that the cancer is early and that it has low risk of metastasis. [2] In such cases, medical specialty professional organizations recommend against the use of PET scans , CT scans , or bone scans because research shows that the risk of getting such ...
