High Dose-Rate Intraluminal Irradiation in Bronchogenic Carcinoma

With the escalation of new cases of lung carcinoma in this decade, new approaches to the management of this disease are of utmost importance. In those patients who have previously been treated with external-beam irradiation, repeat treatment is of some value, but palliation is modest and of short duration. Laser debulking has also been used, […]

Diagnostic Efficacy of PET-FDG Imaging in Solitary Pulmonary Nodules: Conclusion

Bronchoscopy with transbronchial biopsy is considered the least invasive procedure with an overall complication rate under 5 percent. Bronchoscopy is commonly performed in patients with solitary pulmonary nodules larger than 2 cm, and a diagnostic result is obtained in 40 to 80 percent of cases, depending on the size and location of the nodule. A […]

Diagnostic Efficacy of PET-FDG Imaging in Solitary Pulmonary Nodules: Discussion

Our study has demonstrated that the use of PET-FDG imaging, a new noninvasive test, has a high degree of accuracy in differentiating benign from malignant solitary pulmonary nodules less than 3 cm in size. Analysis of the two false-positive cases revealed the following data. In one patient, review of the chest radiographs showed a 2-cm […]

Diagnostic Efficacy of PET-FDG Imaging in Solitary Pulmonary Nodules: Methods

Patient Selection Thirty subjects who presented for evaluation of solitary pulmonary nodules of 3 cm or less were enrolled in this study. Subjects were evaluated at Creighton University Medical Center and the Veterans Affairs Medical Center in Omaha. All patients had plain chest radiographs, and CT scan of the chest and mediastinum was obtained in […]
