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...

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...

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...

Imaging Studies III: Computed Tomography

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...

Radiological Investigation I: X-ray and CT

Radiological Investigation I: X-ray and CT

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 the...

Positron Emission Tomography

Positron Emission Tomography

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body being...

Summary

Chest radiographs effectively identify significant abnormalities in pectus excavatum (pectus) patients, potentially reducing radiation exposure and costs associated with CT scans.

Area of Science:

Pediatric Radiology
Thoracic Surgery
Congenital Abnormalities

Background:

Pectus excavatum is a common chest wall deformity impacting anterior-posterior dimension.
Chest CT is standard for preoperative pectus assessment, evolving from single images to full chest scans.

Purpose of the Study:

To compare the effectiveness of chest radiographs versus chest CT in detecting additional clinically significant abnormalities during preoperative pectus evaluation.
To assess the utility of standard chest X-rays in identifying critical findings.

Main Methods:

Review of chest CT scans from 209 pediatric and young adult patients undergoing pectus evaluation.
Categorization of additional abnormalities into incidental, potentially significant, and surgery-altering findings.
Correlation of chest radiograph findings with category 3 (surgery-affecting) abnormalities.

Main Results:

Seventy-six patients (36%) had additional abnormalities on CT.
Two critical findings (vascular ring, acute pneumonia) affecting surgical decisions were identified.
Both critical findings were also detected on conventional chest radiographs.

Conclusions:

Conventional chest radiographs are valuable for identifying clinically important findings in pectus patients.
Utilizing chest radiographs alongside limited CT techniques can decrease radiation risks and healthcare costs.
This approach is particularly relevant when CT is ordered solely for Haller index calculation.
