Abstract
|
|
|
Background: 99mTechnetium methylene diphosphonates(99mTc MDP) bone scintigraphy is current method of choice for the detection of bone metastases, but whole body 18F-fluoro-deoxy- D-glucose positron emission tomography(18FDG PET) offers superior spatial resolution and improved sensitivity. So we compared whole body 18FDG PET with 99mTc MDP bone scintigraphy in patients with skeletal metastases from lung cancer.
Patients and Methods: Ninety-two patients with lung cancer taken 18FDG PET together with a 99mTc MDP bone scintigraphy within 1 month between March 2000 and March 2003 were investigated retrospectively.
Results: The sensitivity, specificity and accuracy of the 99mTc MDP bone scintigraphy versus 18FDG PET for the detection of bone metastases in lung cancers were 59% vs 82%, 71% vs 94%, and 68% vs 91%, respectively. In the diagnosis of bone metastases from lung cancer, 18FDG PET was statistically superior to 99mTc MDP bone scintigraphy in its specificity and accuracy(p<0.0001).
Conclusions: Whole body 18FDG PET may be useful in detecting bone metastases among patients with lung cancer.
