Radiological Investigation III: Pulmonary Angiogram and PET Scan01:13

Radiological Investigation III: Pulmonary Angiogram and PET Scan

492
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 I: CT and MRI

951
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...

Imaging Studies for Cardiovascular System III: X-Ray

500
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...

Radiological Investigation I: X-ray and CT

1.2K
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...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

652
Description
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...

Nurses' Legal Responsibilities I01:27

Nurses' Legal Responsibilities I

1.7K
In healthcare, informed consent is a crucial process that involves thoroughly communicating medical treatment options to patients, including benefits, risks, potential side effects, and alternatives. This process enables patients to make well-informed decisions about their care, ensuring they understand the implications of their choices before consenting to or refusing treatment.
The legal responsibilities of a nurse regarding informed consent include the following:

Area of Science:

  • Medical Imaging
  • Radiology
  • Patient Safety

Background:

  • Interventional radiology (IR) procedures utilize ionizing radiation.
  • Patient awareness and perception of radiation risks are crucial for informed consent.
  • Current consent practices may not adequately address radiation-specific risks.

Purpose of the Study:

  • To investigate patient perceptions of cancer risk from IR procedures.
  • To determine if informed radiation consent is warranted for IR procedures.

Main Methods:

  • A prospective survey of 68 adult patients undergoing IR procedures with radiation exposure.
  • Utilized a multiple-choice format to assess risk perception and consent preferences.
  • Subgroup analysis based on prior IR history was performed.

Main Results:

  • 81% of patients desired information on a 3% increased cancer risk over 5 years.
  • Awareness of radiation exposure was low (53%).
  • 85% of patients believed consent should include radiation-related cancer risks, particularly those with no prior IR history.

Conclusions:

  • A significant majority of patients desire discussion regarding radiation-related cancer risks.
  • Informed radiation consent, especially for high-dose procedures, should be considered.
  • Shared responsibility for obtaining consent between referring physicians and interventional radiologists is perceived.
