CT texture analysis of pulmonary lesions in patients suspected for lung cancer
نویسندگان
چکیده
Methods Using texture analysis, we analysed 104 lesions in 104 patients suspected for lung cancer with a positive CT correlate. The analysis was performed using TexRAD (developed by TexRAD Ltd. UK). Histology was our reference standard. Malignancy was present in 92 lesions. CTTA comprised a filtration-histogram technique where filtration extracted and enhanced features of different sizes (fine, medium, coarse – scales) followed by histogram analysis using mean (M), entropy (E), uniformity (U), total number of voxels and kurtosis (K) within the entire volume of the suspected lesion. The operator performing the CTTA was blinded to the histological results.

Automated classification of pulmonary nodules through a retrospective analysis of conventional CT and two-phase PET images in patients undergoing biopsy
Objective(s): Positron emission tomography/computed tomography (PET/CT) examination is commonly used for the evaluation of pulmonary nodules since it provides both anatomical and functional information. However, given the dependence of this evaluation on physician’s subjective judgment, the results could be variable. The purpose of this study was to develop an automated scheme for the classific...

This study was undertaken to examine the ability of SPECT in differentiation of a pulmonary lesion suspecions of lung cancr. A total of 170 patients with suspected lung cancer were studied. A dose of Tl-201 chloride {148-296 MBq) was injected intravenously and tomographic early and delayed scans were obtained at 15 miniutes and 3 hours post injection, respectively. Delayed Tl-201 SPECT vi...

Introduction: Lung cancer is the disease of modern era, and the rate of lung cancer mortality is three times as high as that for prostate cancer and twice as high as the rate for breast cancer. We aimed to analyze the results of pulmonary resection in patients with NSCLC by minimally invasive thoracoscopy. Materials and Methods: We studied 10 patients with NSCLC scheduled for surgical resectio...

Background. Positron emission tomography/computed tomography (PET/CT) is recommended for colorectal cancer (CRC) patients with suspected malignant pulmonary lesions. This study aims to systematically discuss the 18F-FDG-PET/CT diagnosis of solitary pulmonary lesions that are strongly suspected to be malignant in CRC patients who have previously undergone curative therapy. Methods. This retrospe...
