Initial study of whole-body MRI value in assessement of lung cancer staging

SUMARY:

Purpose: This study aims to describe the characteristic of the primary and mestastasis lesions of pulmonary cancer on wholebody MRI and to study the value of whole-body MRI in assessement of pulmonary tumor staging.

Materials and methods: Prospective and describe study included 46 patients, confirmed of lung cancer base on histopathology, from January to October 2011 in Bach Mai Hospital. All of them were done whole-body MRI and 21 patients in which were taken FDG-PET/CT. The imaging characteristic of original tumor and metastasis lesions were describe on whole-body MRI. Assessement of lung cancer staging on whole-body MRI was compared with FDG-PET/CT.

Results: The mean diameter of original tumor is about 44.4±22.15mm. The average restriction of lung cancer is about 4.02±0.83 points. 67.5% of lung cancer presented mediastinal and pleural invasion. The metastasis rate of lymph node, bone, brain, liver and adrenal gland were 54.3%; 28.3%; 26.1%; 15.2% and 8.6% respectively. Assessement of lung cancer staging according to T, N, M and TNM between 2 methods of whole-body MRI and FDG-PET/CT with Kappa coefficence were 0.601; 0.516; 0.904 and 0.846 respectively, p < 0.05.

Conclusion: High field whole-body MRI were considered as an alternative modality to assess the lung cancer staging.
