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

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 for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

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...

Summary

Celiac plexus blocks using the celiac trunk landmark risk vital organ injury due to anatomical variations. Pre-procedural computed tomography (CT) imaging is recommended for safe needle placement during celiac plexus blocks.

Area of Science:

Radiology
Anatomy
Pain Management

Background:

The celiac plexus, a key autonomic network, is targeted for pain management via blocks using the celiac trunk as a landmark.
Needle placement techniques, particularly the
walking-off
method, may lead to inadvertent puncture of adjacent organs due to anatomical variability.

Purpose of the Study:

To investigate the topography of the celiac trunk and surrounding structures using computed tomography (CT) imaging.
To assess the risk of vital organ traversal during simulated celiac plexus block needle placement.

Main Methods:

Review of 200 computed tomography (CT) images to analyze celiac trunk emergence, aortic location, and vertebral anatomy.
Simulation of needle trajectories using the
walking-off
technique at fixed distances from the midline (L-9s and L-4.5s).
Identification and analysis of vital organs traversed by simulated needle paths.

Main Results:

Significant variability in celiac trunk emergence levels (T11-L1) and its relationship with the aorta and vertebrae.
High rates of simulated needle trajectories traversing vital organs: 88% and 96% for L-9s (right and left), and 64% and 88% for L-4.5s (right and left), respectively.
Demonstrated frequent overlap between simulated needle paths and organs such as the liver, spleen, pancreas, and kidneys.

Conclusions:

Anatomical variations of the celiac trunk and surrounding structures are common.
Standardized needle insertion techniques for celiac plexus blocks carry a significant risk of injuring adjacent vital organs.
Individualized pre-procedural CT imaging and simulated needle placement are crucial for optimizing safety and efficacy in celiac plexus blocks.
