Computed Tomography01:10

Computed Tomography

7.9K
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...

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...

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...

Area of Science:

  • Medical Imaging
  • Nuclear Medicine
  • Radiology

Background:

  • Long-axial-field-of-view (LAFOV) PET/CT scanners offer improved sensitivity over conventional systems.
  • Optimizing LAFOV PET/CT protocols requires workflow adjustments impacting patient experience.
  • This study evaluates patient workflow and experience during the transition to LAFOV PET/CT.

Purpose of the Study:

  • To compare patient workflow and experience between conventional and LAFOV PET/CT systems.
  • To assess the impact of LAFOV PET/CT on patient time spent in different facility areas.
  • To evaluate patient concerns, discomfort, and perceptions of care after LAFOV PET/CT implementation.

Main Methods:

  • Observational study comparing patient movement in conventional and LAFOV PET/CT facilities.
  • Median times in uptake room, camera room, hallway, and toilet were compared.
  • A survey assessed patient concerns, physical discomforts, and staff care perceptions using a 5-point Likert scale (108 conventional, 105 LAFOV responses).

Main Results:

  • LAFOV PET/CT patients spent significantly less time in camera and uptake rooms.
  • Fewer patients felt scans were too long, were concerned about radiation, or anxious with LAFOV PET/CT.
  • No significant differences in perceived staff care or physical discomforts (including claustrophobia) were found.

Conclusions:

  • Transitioning to LAFOV PET/CT reduces stationary time and patient concerns.
  • LAFOV PET/CT implementation improves patient experience without increasing physical discomfort.
  • LAFOV PET/CT systems enhance imaging efficiency while maintaining or improving patient comfort and care perception.
