Radiological Investigation III: Pulmonary Angiogram and PET Scan01:13

Radiological Investigation III: Pulmonary Angiogram and PET Scan

619
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...

Imaging Studies for Cardiovascular System III: X-Ray

630
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 Imaging

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...

Radiation: Applications

2.0K
The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.
The average...

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Area of Science:

  • Medical Physics
  • Radiological Protection
  • Ophthalmology

Background:

  • Ionizing radiation use in medicine is generally safe for patients and staff.
  • Interventional radiology procedures, utilizing fluoroscopy, involve high radiation doses, necessitating improved safety measures.
  • Recent data suggest radiation-induced cataracts may not be deterministic, leading to revised safety thresholds.

Purpose of the Study:

  • To review and recommend intensified radiation protection strategies in interventional radiology.
  • To emphasize the importance of comprehensive protective measures, including eye protection.
  • To assess the feasibility of meeting the International Commission on Radiological Protection's updated eye dose limits.

Main Methods:

  • Review of current radiation protection practices in interventional radiology.
  • Analysis of data on radiation-induced cataractogenesis.
  • Evaluation of the effectiveness of protective equipment, including lead aprons, lead glass, and lead eyeglasses.

Main Results:

  • The development of cataracts may occur at lower radiation doses than previously thought.
  • The International Commission on Radiological Protection has reduced the recommended annual eye dose limit from 150 mSv to 20 mSv.
  • Comprehensive application of all available X-ray protection measures, including lead-containing eyeglasses, can achieve these new dose limits.

Conclusions:

  • Intensified radiation protection is crucial in modern interventional radiology.
  • Personal protective equipment, particularly eye protection, is vital for minimizing occupational radiation exposure.
  • Adherence to updated guidelines and utilization of advanced protective tools are essential for preventing radiation-induced eye injuries.
