Radiological Investigation III: Pulmonary Angiogram and PET Scan01:13

Radiological Investigation III: Pulmonary Angiogram and PET Scan

193
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

321
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...

Cardiac Catheterization IV: Nursing Management

294
Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...

Cardiac Catheterization I: Pre-Procedure Overview

280
Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

359
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Imaging Studies for Cardiovascular System V: CT

100
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Area of Science:

  • Medical Imaging
  • Radiation Oncology
  • Cardiology

Background:

  • Minimizing radiation exposure for healthcare professionals during cardiac catheterization procedures is crucial.
  • Scattered radiation from patients is a primary source of occupational radiation risk.

Purpose of the Study:

  • To evaluate the effectiveness of simple partial patient shielding in reducing radiation dose.
  • To assess the impact of lead-based aprons on lower extremities during cardiac catheterization.

Main Methods:

  • A prospective study involving 112 patients undergoing cardiac catheterization.
  • Patients were divided into two groups: one with lead aprons on lower extremities, and a control group without shielding.
  • Radiation doses were measured and compared between the two groups.

Main Results:

  • The shielded group (332 min 45 sec) had a higher angiography duration than the unshielded group (269 min 10 sec).
  • Despite longer procedure times, the shielded group received a total radiation dose of 33 μGy, compared to 606 μGy in the unshielded group.
  • A 22-fold reduction in total radiation dose was observed in the group with simple lower extremity shielding.

Conclusions:

  • Simple partial shielding of patients with lead-based aprons is a highly effective method for reducing radiation exposure.
  • This cost-effective technique significantly enhances safety for operators and personnel in the cardiac catheterization laboratory.
  • Implementing this shielding strategy can lead to substantial reductions in occupational radiation doses without additional financial burden.
