The pulmonary nodule: change of paradigm
نویسنده
چکیده
The threshold for detection of pulmonary nodules has decreased due to advances in CT technology. Particularly in sub-centimetre nodules, non-invasive diagnostic procedures are required for classification into benign and malignant to avoid unnecessary invasive procedures as more than 95% of these lesions are benign.

The Value of LDH Level of BAL Fluid in Differentiating Benign from Malignant Solitary Pulmonary Nodules
Background: Serum lactate dehydrogenase (LDH) concentration is an indicator for tissue injury. It may be secreted locally in many conditions. For the first time, this study was performed to investigate the value of LDH level in bronchoalveolar lavage fluid (BALF) in differentiation of benign from malignant single pulmonary nodules (SPNs) and to assess its relationship with serum LDH levels. Met...

Introduction: In the lung cancers, a computer-aided detection system that is capable of detecting very small glands in high volume of CT images is very useful.This study provided a novelsystem for detection of pulmonary nodules in CT image. Methods: In a case-control study, CT scans of the chest of 20 patients referred to Yazd Social Security Hospital were examined. In the two-dimensional and ...
متن کاملAutomated approach to measure pulmonary nodule volume based on radius and CT number
Determining the change in the pulmonary nodule size is a critical measurement for cancer diagnosis and therapy evaluation. In this study, an image-processing method that quantifies the nodule volume change based on computed tomography (CT) images is proposed. The proposed method consists of the following four steps: CT image interpolation, pulmonary region segmentation, nodule extraction, and n...
