Multicenter Study Clinical TrialImpact of (18)F-FDG PET on treatment strategy and 3D radiotherapy planning in non-small cell lung cancer: A prospective multicenter study.
The purpose of our study was to quantify the impact of preradiotherapy (18)F-FDG PET when deciding whether radiotherapy should be curative or palliative in intent and defining its detailed planning in patients with non-small cell lung cancer referred for 3D conformal radical radiotherapy within a large prospective multicenter study. ⋯ Preradiotherapy FDG PET for non-small cell lung cancer patients referred for 3D conformal radiotherapy may lead to significant modification of treatment strategy and radiotherapy planning.

Quantitative assessment of bronchial wall attenuation with thin-section CT: An indicator of airflow limitation in chronic obstructive pulmonary disease.
The purpose of this study was to evaluate the relation between bronchial wall attenuation on thin-section CT images and airflow limitation in persons with chronic obstructive pulmonary disease. ⋯ Peak attenuation of the bronchial wall measured at CT correlates significantly with expiratory airflow obstruction in subjects with chronic obstructive pulmonary disease, particularly in the distal airways.

MRI evaluation of collapsed femoral heads in patients 60 years old or older: Differentiation of subchondral insufficiency fracture from osteonecrosis of the femoral head.
The purpose of this article is to verify the hypothesis that osteonecrosis and subchondral insufficiency fracture of the femoral head can be differentiated on the basis of their appearance on MRI. ⋯ The results of the present study suggest that the shape of the low-intensity band on MRI is useful for the differentiating subchondral insufficiency fracture from osteonecrosis. In addition, among osteoporotic elderly women without any history of corticosteroid intake or alcohol abuse, a diagnosis of subchondral insufficiency fracture should be considered.
