Imaging Studies III: Computed Tomography

33
DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

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...

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

224
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...

Imaging Studies for Cardiovascular System V: CT

53
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...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Area of Science:

  • Trauma care systems
  • Medical imaging
  • Health services research

Background:

  • Repeat imaging in rural trauma patients transferred to tertiary centers is common, leading to increased radiation, costs, and care delays.
  • Previous reviews indicated frequent pre-transfer CT scans with minimal impact on management.
  • Initiatives focused on improving imaging practices and telehealth guidelines were implemented to reduce unnecessary scans.

Purpose of the Study:

  • To evaluate the impact of trauma system improvements on the rates of pre-transfer and repeat CT scans in a rural trauma system.
  • To assess the effectiveness of enhanced training, feedback, and telehealth guidelines in optimizing imaging practices.

Main Methods:

  • A retrospective evaluation of 200 consecutive adult trauma patients transferred to a regional trauma center.
  • Comparison of imaging data with a previous cohort before system improvements.
  • Analysis of pre-transfer CT scan rates and repeat scans upon arrival.

Main Results:

  • A statistically significant decrease in pre-transfer CT scans from 77.2% to 70% (P = .0112).
  • A significant reduction in repeat CT scans upon arrival from 55.3% to 37.1% (P < .0001).
  • Incomplete initial imaging was the primary reason for repeat scans; head injuries were more common in patients requiring repeat scans.

Conclusions:

  • Regional trauma system maturation and telehealth guidelines led to a significant decrease in both pre-transfer and repeat CT scans.
  • The findings suggest improved efficiency and potentially reduced radiation exposure and costs in rural trauma care.
  • Further research on patient outcomes and cost savings is recommended.
