Computed Tomography01:10

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: Gastrointestinal Motility Studies and Virtual Colonoscopy

This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...

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 for Cardiovascular System V: CT

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...

Imaging Studies VI: Voiding Cystourethrography and Cystography

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...
Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies01:28

Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies

Peptic ulcer disease (PUD) presents with diverse symptoms depending on the location and severity of the ulcer. Clinical manifestations of peptic ulcer include dull pain and a burning sensation in the mid-epigastric region.
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.

Area of Science:

  • Veterinary Radiology
  • Medical Imaging
  • Gastroenterology

Background:

  • Helical hydro-computed tomography (CT) is a diagnostic imaging technique.
  • It utilizes water as a neutral luminal contrast medium alongside intravenous iodine contrast for imaging.
  • This method is explored for diagnosing gastric neoplasia in humans.

Purpose of the Study:

  • To evaluate the feasibility of helical hydro-CT for assessing the stomach wall in animals.
  • To determine the optimal water volume for gastric distension in dogs and cats.
  • To assess the diagnostic utility of helical hydro-CT in animals with suspected gastric neoplasia.

Main Methods:

  • Helical hydro-CT was performed on 11 healthy animals (9 dogs, 2 cats) to establish feasibility and optimal water volume (30 ml/kg).
  • Fourteen dogs and 4 cats with suspected or diagnosed gastric neoplasia underwent helical hydro-CT with intravenous contrast.
  • Image analysis focused on gastric wall distension, contrast enhancement, and lesion assessment.

Main Results:

  • Adequate and uniform gastric distension was achieved with 30 ml/kg of water.
  • Focal thickening with moderate contrast enhancement, indicative of neoplasia, was identified in 10 dogs and 3 cats.
  • The extent of lesions was easily assessed in affected animals; 3 dogs and 1 cat had normal stomach walls.

Conclusions:

  • Helical hydro-CT, combined with intravenous contrast, is a simple and effective technique for evaluating the stomach wall in animals.
  • The method facilitates the diagnosis and staging of gastric neoplasia in veterinary patients.
  • This imaging modality offers a valuable tool for gastrointestinal diagnostics in dogs and cats.
