Combination of FDG PET/CT and contrast-enhanced MSCT in detecting lymph node metastasis of esophageal cancer.

Background: Lymph node metastasis is believed to be a dependent negative prognostic factor of esophageal cancer. To explore detection methods with high sensitivity and accuracy for metastases to regional and distant lymph nodes in the clinic is of great significance. This study focused on clinical application of FDG PET/CT and contrast-enhanced multiple-slice helical computed tomography (MSCT) in lymph node staging of esophageal cancer.

[The value of dual time point 11C-choline PET-CT in differentiating malignant from benign lesion of mediastinum].

Objective: To evaluate the value of dual time point 11C-choline PET-CT in differentiating malignant from benign lesions of mediastinum.

Methods: Thirty-five patients with mediastinal diseases, including 8 non-small cell lung cancer or highly suspected lung cancer patients with mediastinal lymphadenectasis, were subject to CT, dual time point PET-CT and videomediastinoscopy within four weeks. 11C-choline was used as PET tracers to visualize various masses.

The role of 11C-choline positron emission tomography-computed tomography and videomediastinoscopy in the evaluation of diseases of middle mediastinum.

Background: Middle mediastinal masses comprise a wide variety of tumors but may also reflect lymphadenopathy, and thus remain an interesting diagnostic challenge. We performed positron emission tomography (PET) of mediastinal masses in order to evaluate the ability of PET to predict the malignancy of these tumors. We compared histologic findings, videomediastinoscopy, computed tomography (CT), and PET-CT in patients with mediastinal disease.

[Clinical evaluation of 18F-FDE PET-CT in detecting malignant liver tumors].

Objective: To evaluate the clinical value of (18)F-fluorodeoxyglucose ((18)F-FDG) positron-emission tomography (PET) combined with computer tomography (PET-CT) in the diagnosis and clinical staging of liver cancer.

Methods: (18)F-FDG PET-CT was performed preoperatively in 16 cases of primary and 8 metastatic liver cancers. The imaging features of the primary foci were analyzed, followed by measurement of standardized (18)F-FDG uptake.
