PURPOSE A newly isolated mediastinal lymph node (LN) or a small pulmonary nodule, which appears during breast cancer surveillance, may pose a diagnostic dilemma with regard to malignancy. We conducted this study to determine which clinical factors were useful for the differentiation of malignant lesions from benign lesions under these circumstances. MATERIALS AND METHODS We enrolled breast ca...
Detection of malignant lung nodules in chest radiographs is currently performed by pulmonary radiologists, potentially with the aid of CAD systems. Recent advancements in convolutional neural network (CNN) models have improved image classification and detection for many tasks, but there has been little exploration of their use for nodule detection in chest radiographs. In this paper we explore ...
UNLABELLED INTRODUCTION When a pulmonary nodular lesion is detected by F-18 fluorodeoxyglucose positron emission tomography-computed tomography in a patient with post-surgical papillary thyroid carcinoma with undetectable serum-stimulated thyroglobulin levels and negative 131I whole body scan, diagnosis and management of the nodule may be confusing. CASE PRESENTATION We describe two post-s...
New opportunities for research in computer aided diagnosis (CAD) of pulmonary nodules resulted from the emergence of publicly available clinical case studies, containing expert radiologist-defined truth. Access to high-quality labeled data affords non-clinical image analysis groups the opportunity to pursue diagnostic imaging research. Historically, clinical research centers reported results ba...
Solitary pulmonary nodule (SPN) is a frequent finding on the chest x-ray and computed tomography. Nuclear medicine techniques play an important role in the diagnosis and management of SPN. In the current review, we briefly will explain the different nuclear medicine modalities in this regard including positron emission tomography (PET) using 18-F-FDG, and 11-C-Methionine, and single photon em...
tuberculos gumma is one of the various clinical manifestations of cutaneous tb that is characterized by non tender, undolent subcutaneous nodules which progressively involve the skin and take the appearance of an ulcer. in this article, we present two young patients, affected with tuberculos gumma. one of them, presented with multiple abcesses on the face and extremities, associated with pulmon...
BACKGROUND The minimal invasive investigation of solitary pulmonary nodules becomes increasingly important with the emergence of lung cancer screening. OBJECTIVES We report the results of the first utilization of a recently developed procedure in a bronchoscopy suite, which approaches solitary pulmonary nodules via a transparenchymal path. METHODS This study was a prospective, single-arm in...
