Increased utilization of chest CT examination has resulted in a dramatic escalation in the number of newly detected solitary pulmonary nodules, defined as round lesions <3 cm in diameter surrounded by lung parenchyma. Although the risk of finding cancer is 3040% in radiographically discovered pulmonary nodules, thin section CT is 10-20 times as sensitive and can detect much smaller nodules. Siz...

Amyloid-like pulmonary nodules have been described in patients with systemic light-chain deposition disease, but their significance in other clinical contexts is unknown. We examined biopsy specimens of amyloid-like pulmonary nodules from 3 women without systemic light-chain deposition disease. Patient 1 (aged 62 years) had multiple pulmonary nodules and underwent 2 separate lung biopsies, the ...

BACKGROUND Virtual-assisted lung mapping is a novel bronchoscopic lung marking technique that uses virtual images to perform multiple concurrent dye marking of barely palpable pulmonary tumors. Subsequent chest computed tomography is required to confirm the locations marked. We here report a patient in whom computed tomography after virtual-assisted lung mapping unexpectedly revealed additional...

background : the data related to patients often have very useful information that can help us to resolve a lot of problems and difficulties in different areas. this study was performed to present a model-based data mining to predict lung cancer in 2014. methods : in this exploratory and modeling study, information was collected by two methods: library and field methods. all gathered variables w...

A solitary pulmonary nodule (SPN) is radiologically defined as an intraparenchymal lung lesion that is < 3 cm in diameter and is not associated with atelectasis or adenopathy. Lung lesions > 3 cm in size are defined as lung masses. A solitary pulmonary nodule is noted on 0.09 to 0.20 per cent of all chest radiographs. An estimated 150,000 such nodules are identified each year. Ninety per cent o...

Small pulmonary nodules are radiologic findings that represent an important challenge in diagnosis systems. While these nodules are the major indicator for lung cancer and metastasis, their properties like size and location play an important role in classifying the benign one from the malignant. Estimating the growth rate of the nodule size states the degree of malignancy. This paper presents a...
