Nasal fractures are usually identified visually and through physical examination. [1] In addition, relevant questions to ask the patient include whether there is a noticeable cosmetic deformity and whether the patient has difficulty breathing through the nose after the injury.
The Pancoast tumor was first described by Hare in 1838 as a "tumor involving certain nerves". [2] It was not until 1924 that the tumor was described in further detail, when Henry Pancoast, a radiologist from Philadelphia, published an article in which he reported and studied many cases of apical chest tumors that all shared the same radiographic findings and associated clinical symptoms, such ...
This imaging modality uses a wide beam of X-rays for image acquisition and is the first imaging technique available in modern medicine. Fluoroscopy produces real-time images of internal structures of the body in a similar fashion to radiography, but employs a constant input of X-rays, at a lower dose rate.
Lung cancer most commonly metastasizes to the brain, bones, liver, and adrenal glands. [14] Lung cancer can often appear as a solitary pulmonary nodule on a chest radiograph or CT scan. In lung cancer screening studies as many as 30% of those screened have a lung nodule, the majority of which turn out to be benign. [15]
Imaging Studies: Chest X-rays, CT scans, PET, or PET-CT scans are the most commonly used imaging modalities to help identify the size, location, and extent of the tumor. [ 1 ] Biopsy : Done by obtaining a piece of tissue from the tumor, classically done through bronchoscopy or CT guided needle biopsy, to study the histology of the tissue and ...
A radiation source is positioned behind the patient at a standard distance (most often 6 feet, 1,8m), and the x-ray beam is fired toward the patient. In anteroposterior (AP) views, the positions of the x-ray source and detector are reversed: the x-ray beam enters through the anterior aspect and exits through the posterior aspect of the chest.
Adenocarcinoma of the lung is the most common type of lung cancer, and like other forms of lung cancer, it is characterized by distinct cellular and molecular features. [1] It is classified as one of several non-small cell lung cancers (NSCLC), to distinguish it from small cell lung cancer which has a different behavior and prognosis.
