Overview
Positron Emission Tomography (PET) scan may be diagnostic of multiple myeloma.
Positron Emission Tomography Scan
- Positron emission tomography (PET) scan is a highly specific diagnostic tool for diagnosing multiple myeloma.[1][2]
- Uptake of the F18-FDG molecule by the multiple myeloma lesions corresponds to areas of bone lysis seen on PET-CT scan.[3]
- PET scan is superior than either CT scan or MRI for diagnosis of multiple myeloma.[1][2][4]
- In addition, PET scan is useful in the detection of cancer spread to distant lymph nodes.[1][2]
- When PET scan is used in combination with MRI the diagnostic efficacy may almost reach 100%.[1][2]
- The use of PET scan has led to earlier diagnosis of multiple myeloma annd increased the accuracy of therapy response assessment.[5]
- PET scan has still not been employed as a standard of care by the International Myeloma Working Group.[5]
