Nuclear medicine imaging of lung cancer.

摘要: Although nuclear medicine imaging is still widely under-appreciated and underused by the medical radiologic communities, FDG PET Tc 99m depreotide SPECT are safe, cost-effective methods with advantages over CT other in diagnosis management of patients suspected or known to have lung cancer. Physicians involved care these should familiarize themselves both relatively new procedures. Both F-18 a high degree sensitivity, specificity, overall accuracy, PPV NPV solitary pulmonary nodule. Nuclear either agents provides noninvasive, method select for aggressive intervention without contributing increased morbidity. There has not been direct comparison two techniques terms their relative role cost-effectiveness incremental value selecting nodules invasive biopsy thoracotomy. To date, only proved additional application in: 1. Improving staging identifying excluding mediastinal disease. Some authors reluctant at present time deny an opportunity curative resection based on finding foci metabolism mediastinum (characterized activity) because there occasional false-positive studies. They propose, however, that negative study justifies surgical approach (and cure) regardless findings CT. 2.

It too soon, know if imaging, properly performed, can mimic success exclusion metastases, evaluating response therapy, recurrent disease during post-therapeutic monitoring.
