Radiological Investigation I: X-ray and CT01:30

Radiological Investigation I: X-ray and CT

226
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 III: Pulmonary Angiogram and PET Scan

91
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

228
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...

Computed Tomography01:10

Computed Tomography

4.5K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

111
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...

Imaging Studies for Cardiovascular System III: X-Ray01:20

Imaging Studies for Cardiovascular System III: X-Ray

171
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...

Summary

Pediatric renal failure is common in emergency departments, challenging assumptions of normal kidney function. Further research is needed for guidelines on contrast-enhanced imaging in children with unknown renal status.

Area of Science:

  • Pediatric Nephrology
  • Diagnostic Imaging
  • Emergency Medicine

Background:

  • Renal failure occurs more frequently in pediatric emergency department patients than often assumed.
  • Current practices may not adequately account for potential renal dysfunction in children undergoing imaging.

Purpose of the Study:

  • To highlight the need for assessing renal function in pediatric patients before contrast-enhanced computed tomography (CT) scans.
  • To underscore the lack of specific guidelines for contrast administration in pediatric patients with unknown renal function.

Main Methods:

  • Review of current clinical scenarios and assumptions regarding pediatric renal function.
  • Identification of the gap in pediatric-specific guidelines for contrast-enhanced imaging.

Main Results:

  • The assumption of normal renal function in pediatric emergency department patients is frequently invalid.
  • There is a lack of established pediatric prevention strategies and guidelines for contrast use.

Conclusions:

  • Pre-imaging assessment of renal function is crucial in pediatric patients, especially before contrast-enhanced CT.
  • Further research is required to develop evidence-based recommendations for contrast-enhanced examinations in pediatric populations with unknown renal function.
