Brief Title: Dual Energy Computed Tomography (CT) in Finding Bone Metastases in Patients With Cancer
Official Title: Evaluation of Bone Metastases With Dual Energy Computed Tomography (CT)
Study ID: NCT02354326
Brief Summary: This clinical trial studies dual energy computed tomography (CT) in finding cancer that has spread from the original (primary) tumor to the bone (bone metastases) in patients with cancer. Diagnostic procedures, such as dual energy CT, may help find and diagnose bone metastases and may be more accurate compared to single energy CT alone.
Detailed Description: PRIMARY OBJECTIVES: I. Compare the accuracy of single energy CT (SECT) with virtual non-calcium (VNC) double energy CT (DECT) to standard SECT alone in the detection of metastatic bone lesions using positron emission tomography (PET)-CT as the reference standard. OUTLINE: Computed tomography (CT) scans are routinely used in the evaluation of oncologic patients for initial diagnosis and subsequent disease staging. Detection of bone metastasis on standard CT, however, is limited in sensitivity, particularly in case of osteolytic intramedullary lesions. Recent studies have shown the ability to detect bone marrow edema using CT with the use of a virtual non-calcium (VNC) dual energy CT (DECT) technique. Because bone marrow edema is similar in composition to intramedullary bone metastases (i.e. both are of soft tissue composition as opposed to calcium or fat), VNC DECT may also be helpful in the detection of bone marrow metastasis. Cancer patients obtaining a Positron Emission Tomography (PET) CT and a separate diagnostic CT scan as part of their routine clinical care will be enrolled into the study. The diagnostic CT scan will be performed on a DECT scanner and the images will be reconstructed as SECT images for routine clinical interpretation as well as VNC DECT images. The SECT images alone will be evaluated and scored, and then the VNC DECT images will be added to the SECT images for a second evaluation (consecutive reading session). Multiple readers blinded to the PET-CT findings for detection of bony metastatic disease will participate. Researchers hypothesize the addition of VNC DECT to SECT will be more accurate in the detection of metastatic bone marrow lesions compared to SECT alone.
