[X-ray diagnosis of malignant non-epithelial tumors of the lung]
Abstract:
The paper is devoted to analysis of the investigation and treatment of 137 patients with histologically verified lung sarcoma. X-ray was the chief method of primary detection. A classification, singling out 3 types, was developed: peripheral (82.6%), central (16%) and disseminated (1.4%). The first one included nodular (76%) and pneumonia-like (6.6%) types of changes, the second one--endobronchial changes (11%), peribronchial (2.9%) and exobronchial nodular (2.1%) changes. The developed roentgenosemeiotics made it possible to diagnose malignancy in 72% of the patients, indicating its nonepithelial nature in 36%.

Radiological Investigation I: X-ray and CT
Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
Imaging Studies for Cardiovascular System III: X-Ray
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
