Relationship Between Diseased Lung Tissues on Computed Tomography and Motion of Fiducial Marker Near Lung Cancer

Relationship between diseased lung tissues on computed tomography and motion of fiducial marker near lung cancer.

PURPOSE For lung cancer patients with poor pulmonary function because of emphysema or fibrosis, it is important to predict the amplitude of internal tumor motion to minimize the irradiation of the functioning lung tissue before undergoing stereotactic body radiotherapy. METHODS AND MATERIALS Two board-certified diagnostic radiologists independently assessed the degree of pulmonary emphysema a...

Influences of cardiac motion on computed tomography-guided biopsy of lung nodules located near the heart

Computed tomography (CT)-guided lung biopsy of nodules located near the heart may be associated with potential complications. To understand the influences of cardiac motion on lung parenchyma during biopsy, we processed the cardiac phase images of coronary CT angiography (CCTA) and noticed shifts in mediastinum lung margin (MLM) at different zones.Thirty eight CCTA (27 men and 11 women) were re...

Computed tomography screening and lung cancer outcomes.

CONTEXT Current and former smokers are currently being screened for lung cancer with computed tomography (CT), although there are limited data on the effect screening has on lung cancer outcomes. Randomized controlled trials assessing CT screening are currently under way. OBJECTIVE To assess whether screening may increase the frequency of lung cancer diagnosis and lung cancer resection or may...

Computed tomography in staging for lung cancer.

Computed tomography (CT) provides the most detailed imaging information, hence it is generally used as a routine imaging procedure in the tumour, node, metastasis (TNM)-staging of patients with lung cancer. However, despite the continuously ongoing process of improvement in CT scanning in which today's CT scanners combine fast acquisition, fast data reconstruction and high detail, the technique...
