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 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...

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 IV: Magnetic Resonance Imaging

Imaging Studies IV: Magnetic Resonance Imaging

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

Summary

This study validates a new method for measuring gastric emptying, finding impaired emptying after peptic ulcer surgery correlates with vagotomy extent. Enterogastric reflux patterns were also examined.

Gastroenterology
Nuclear Medicine
Surgical Outcomes

Background:

Accurate measurement of gastric emptying is challenging, particularly relating counts to stomach volume.
Gastric ulcer patients present anatomical complexities (large stomach, bowel overlap) complicating imaging.
Previous studies suggest links between post-surgical gastric emptying and surgical extent.

Purpose of the Study:

To validate a novel method for measuring gastric emptying against gastric aspiration.
To investigate the relationship between impaired gastric emptying and surgical factors in peptic ulcer patients.
To examine enterogastric reflux patterns and their correlation with bile volume and surgical parameters.

Main Methods:

Development and validation of a new gastric emptying measurement technique.
Gastric emptying studies in patients post-peptic ulcer surgery.
Analysis of biliary excretion patterns using iminodiacetic acid derivatives.
Gastric aspiration to quantify bile volume and assess reflux.

Main Results:

The developed method for gastric emptying measurement was validated against gastric aspiration.
Impaired gastric emptying in post-surgical peptic ulcer patients correlated with the extent of vagotomy and pyloric surgery.
Enterogastric reflux reproducibility was 75%, likely due to daily variations; its incidence was studied in relation to vagotomy and Roux-en-Y loop length.
Findings regarding liver to heart ratios in diagnosing biliary atresia were not confirmed.

Conclusions:

A validated method for gastric emptying measurement is presented.
Surgical interventions for peptic ulcers significantly impact gastric emptying, related to vagotomy and pyloric procedures.
Enterogastric reflux is a relevant factor in post-surgical patients, influenced by surgical technique.
Further investigation is needed into the diagnostic utility of radiopharmaceuticals for biliary atresia.
