Lung Cancer, Adenocarcinoma Clinical Trial
Official title:
Low-dose Protocol for Computed Tomography-guided Lung Biopsy
The purpose of this study is to compare the diagnostic accuracy and complication rate between low-dose computed tomography-guided and standard-dose computed tomography-guided lung biopsy.
With the comprehensive usage of computed tomography examination, patients are more and more
aware of the radiation dose of computed tomography. Concerns over the potential for radiation
induced malignancies have increasingly been published in the scientific literature and
reported in the popular press. The risk is highest for younger patients, who have more
radiation-sensitive tissues and longer life expectancies than adults. Recently, the United
States Food and Drug Administration announced an initiative to reduce unnecessary radiation
exposure from medical imaging. At present, low-dose computed tomography protocol is widely
used for the diagnosis of cardiovascular and cerebrovascular diseases.
Computed tomography-guided lung biopsy is widely used for diagnosis of lung nodules and
masses. However, it requires repeating scanning to guide the needles, which inevitably
increases the radiation dose. Therefore, low-dose protocol was also used in the computed
tomography-guided lung biopsy procedure.
The purpose of this study is to compare the diagnostic accuracy and complication rate between
low-dose computed tomography-guided and standard-dose computed tomography-guided lung biopsy.
