Imaging Studies III: Computed Tomography01:27

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 VII: Vascular Imaging

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

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 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...

Area of Science:

  • Radiology
  • Medical Imaging
  • Health Informatics

Background:

  • Power injectors are crucial for contrast-enhanced imaging.
  • Current methods for recording injection data can be fragmented.
  • Integrating injection data into imaging studies can improve workflow and patient safety.

Purpose of the Study:

  • To introduce a novel power injection technology that generates contrast injection data as a DICOM image.
  • To determine the percentage of patients with captured injection data in DICOM format.
  • To analyze the properties of contrast injections for these patients.

Main Methods:

  • A retrospective evaluation of 242 contrast-enhanced CT studies was conducted.
  • Data on patient identifiers, injection volumes, flow rates, and pressures were collected.
  • A literature review on power injectors in radiology was performed.

Main Results:

  • Contrast injection data was successfully incorporated into radiology images for 98% of the evaluated CT studies.
  • Mean residual contrast volume was 5 mL, with minimal differences between prescribed and actual flow rates.
  • No contrast extravasations were reported, and the injection data was available to radiologists as a DICOM image.

Conclusions:

  • Contrast injection data can be effectively captured in DICOM format.
  • This data can be reliably attached to CT image sets for radiologist use.
  • The new technology enhances the integration of injection parameters into the patient's medical record.
