Can bone cancer be diagnosed by 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.

What do dark spots on a bone scan indicate?

What can be seen on a bone scan?

Why would a doctor order a bone scan?

What does a bone scan show that an MRI doesn t?

An MRI creates 3D images of the bone, whereas a bone scan creates two-dimensional (2D) images. The MRI provides a detailed view of the bone and its surrounding structures such as the ligaments, tendons and soft tissue. It diagnoses a bone condition more definitively and accurately than a bone scan.

How long does it take to get the results of a bone scan?

A radiologist will interpret the images, write a report, and deliver the results to your doctor via the internal computer system. This process usually takes less than 24 hours.
