Detailed explanation-1: -Technetium-99m (99mTc) bone scintiscanning (ie, radionuclide bone scanning) is widely regarded as the most cost-effective and available whole-body screening test for the assessment of bone metastases. Conventional radiography is the best modality for characterizing lesions that are depicted on bone scintiscans.

Detailed explanation-2: -Computed tomography (CT) scan A CT scan is more likely to show lung tumors than routine chest x-rays. It can also show the size, shape, and position of any lung tumors and can help find enlarged lymph nodes that might contain cancer that has spread.

Detailed explanation-3: -Using a bone scan when cancer is suspected can be particularly helpful because the scan can find both primary cancer-or, cancer that started in your bones-and bone metastases, which is cancer that has spread to the bones from another part of your body.

Detailed explanation-4: -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.
