Imaging Studies III: Computed Tomography

885
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...

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...

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 I: CT and MRI

1.3K
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...

Radiological Investigation I: X-ray and CT

1.7K
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

713
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...

Area of Science:

  • Pediatric Surgery
  • Medical Imaging
  • Congenital Abnormalities

Background:

  • Pectus excavatum (PE) is the most frequent congenital chest wall anomaly in children.
  • It impacts males more than females (5:1 ratio) and often presents within the first year of life.
  • Adolescents may experience exercise intolerance and psychological distress due to the deformity.

Purpose of the Study:

  • To review the clinical presentation of Pectus excavatum.
  • To discuss the role of imaging in PE diagnosis and severity assessment.
  • To explore methods for reducing radiation exposure during imaging.

Main Methods:

  • Review of clinical features associated with Pectus excavatum.
  • Analysis of imaging modalities, particularly computed tomography (CT) scans.
  • Evaluation of the Haller index for severity grading and insurance criteria.

Main Results:

  • The Haller index, derived from CT scans, is crucial for classifying PE severity (Haller index > 3.2 indicates moderate to severe PE).
  • This index is a key factor for insurance reimbursement for surgical correction.
  • Established surgical interventions include the Nuss and Ravitch procedures.

Conclusions:

  • Understanding PE's clinical aspects and imaging is vital for patient management.
  • Optimizing imaging techniques can reduce radiation dose while maintaining diagnostic accuracy.
  • Accurate assessment via imaging facilitates appropriate treatment and insurance approval.
