Both imaging and image-directed biopsy play a major role in evaluating solitary pulmonary nodules. Imaging is used to determine whether the nodule is actually solitary or if multiple nodules are present. Once a nodule has been detected, imaging techniques can be used to characterize the nodule in terms of whether it is likely benign or malignant. As technology has improved, smaller nodules are ...

OBJECTIVE This study was designed to assess the ability of radiologists to accurately detect calcification within a solitary pulmonary nodule with chest radiography. MATERIALS AND METHODS Thirty-five solitary pulmonary nodules that were examined by both posteroanterior and lateral chest radiography and on thin-section CT were retrospectively identified. Fourteen radiologists blinded to the re...

The lung cancer is the reason of lot of deaths on population around the world. An Which acquired for the processing image. Here the X-Ray images with low dose can used for the nodule identification. The low dose Usually the exiting work of pulmonary nodule identification can be done through the image can be reconstructed through the effective algorithm so called Global Dictionary based Statisti...

The solitary pulmonary nodule is a common lesion that has multiple benign and malignant causes and when detected often creates a diagnostic challenge. Such a challenge is framed on one side by the need to detect and diagnose lung cancer or other malignancies at an early manageable stage and on the other side by the need to restrain from unnecessary intervention on benign lesions. The article wi...

Canine heartworm, Dirofilaria immitis, is a nematode parasite that infects dogs by way of mosquito bite. Rarely, humans play accidental hosts to this parasite and are not a suitable environment for the nematode to live. As the parasite dies in the pulmonary vessels it embolizes the vessels causing infarction and eventual nodule formation in the lungs. In the right clinical context, a nodule can...

With the superb spatial resolution of modern multislice CT scanners and their ability to complete a thoracic scan within one breath-hold, software algorithms for computer-aided detection (CAD) of pulmonary nodules are now reaching high sensitivity levels at moderate false positive rates. A number of pilot studies have shown that CAD modules can successfully find overlooked pulmonary nodules and...

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 emis...

Purpose : The purpose of our study is to describe the chest radiographic and CT findings of simple pulmonary eosinophilia. Materials and Methods : Twenty-six patients with simple pulmonary eosinophilia und e r went chest radiography and CT scanning; the results were analyzed retrospectively by two chest radiologists, focusing on the patterns and distribution of the parenchymal abnormalities. Re...

We herein report a case of solitary pulmonary metastasis from malignant melanoma that presented as a pulmonary ground glass nodule. A 57-year-old man who had undergone resection of a malignant melanoma of the right bulbar conjunctiva at the age of 51 was referred to our hospital for management of ground glass opacity in his left lung. Because radiological examination suggested the nodule was an...

Lung Pulmonary nodules are commonly observed in patients with cancer as well as in patients with no known malignancy particularly in heavy smokers. Most of these nodules are small (less than 8 mm). Even in cancer patients a large proportion of these small nodules are benign [1]. The likelihood of malignancy depends on individual aspects (cancer type, grading, staging, molecular markers etc.), n...
