Radiological Investigation I: X-ray and CT01:30

Radiological Investigation I: X-ray and CT

1.1K
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

Imaging Studies for Cardiovascular System III: X-Ray

466
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
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...

X-ray Imaging01:24

X-ray Imaging

9.9K
German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

Flail Chest-II

543
Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.

Radiological Investigation III: Pulmonary Angiogram and PET Scan

411
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (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...

Assessment of Respiration01:23

Assessment of Respiration

1.8K
The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like...

Area of Science:

  • Occupational Health
  • Radiology
  • Pulmonology

Background:

  • Dockworkers face occupational exposure to respirable particles from dust and diesel exhaust.
  • Silicosis is a significant occupational lung disease associated with silica dust exposure.

Purpose of the Study:

  • To evaluate chest radiological findings in a cohort of dockworkers.
  • To identify factors influencing these radiological findings.

Main Methods:

  • A descriptive study was conducted on dockworkers involved in loading/unloading sand.
  • Chest X-rays were performed between 2016-2023 following the ILO Guidelines.
  • Health surveillance protocols for silicosis exposure were applied.

Main Results:

  • Out of 268 dockworkers, 8.2% (22 males) showed chest radiological abnormalities; no silicosis was detected.
  • Progressive pneumoconiosis-suggestive images were observed in smokers.
  • Other findings included soft tissue, skeletal, or residual pleuroparenchymal lesions.

Conclusions:

  • Preventive measures effectively prevented silicosis in this dockworker group.
  • Smoking is linked to the progression of pneumoconiosis-like changes.
  • Anti-smoking campaigns are crucial for this population.
