Computed Tomography

Computed Tomography

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...

X-ray Imaging

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 X-rays, and by 1900, X-ray was widely...

Imaging Studies III: Computed Tomography

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...

Imaging Studies I: CT and MRI

Imaging Studies I: CT and MRI

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...

Traumatic Memory

Traumatic Memory

Emotionally traumatic events often lead to memories that are exceptionally vivid and enduring, sometimes persisting with remarkable clarity throughout an individual's life. A classic example of this phenomenon is a person who survives a car accident. Even years later, they may recall every detail of the event with startling accuracy — the screeching of the tires, the jarring impact, and the acrid smell of burning rubber. Such vividness contrasts sharply with how an individual remembers mundane...

Ultrasonography

Ultrasonography

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called a...

Summary

Repeat imaging in trauma patient transfers is common, impacting older, severely injured patients and increasing costs. Injury severity score predicts the need for repeat imaging, highlighting areas for improvement.

Area of Science:

Trauma Surgery
Diagnostic Imaging
Health Economics

Background:

Patients referred to trauma centers frequently undergo extensive diagnostic evaluations prior to transfer.
Repeat imaging is a common practice in the care of transferred trauma patients.

Purpose of the Study:

To quantify the incidence and effects of repeat imaging in trauma patient transfers.
To examine the factors influencing the decision for repeat imaging.

Main Methods:

A prospective cohort study involving 410 patient transfers.
Comparison of two groups: patients who underwent repeat imaging versus those who did not.
Analysis of patient demographics, injury severity, and transfer times.

Main Results:

53% of trauma patient transfers involved repeat imaging, with an average cost of $2,985 per patient.
Patients requiring repeat imaging were older, had higher injury severity scores, and experienced longer transfer delays.
Injury Severity Score was identified as an independent predictor for the necessity of repeat imaging (P = .003).

Conclusions:

Severely injured trauma patients often undergo redundant imaging, leading to transfer delays, increased morbidity, and resource utilization.
Implementing targeted education and centralized radiology systems may reduce unnecessary repeat imaging in trauma care.
