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 for Cardiovascular System V: CT

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...

Background:

Imaging departments face challenges in streamlining processes due to healthcare advancements and complex procedures.
Insurance pre-authorizations and restrictions on order changes hinder optimal patient care and revenue.
Centralized scheduling models can lead to financial losses from inappropriately ordered and pre-authorized imaging studies.

Purpose of the Study:

To implement a computed tomography (CT) coordinator role to enhance imaging service throughput.
To utilize a Lean methodology (Plan-Do-Check-Act) to improve process efficiency and revenue in radiology departments.

Main Methods:

Implementation of a CT coordinator position.
Application of the Plan-Do-Check-Act (PDCA) Lean methodology for process optimization.

Main Results:

Streamlined throughput of imaging services within radiology departments.
Increased organizational effectiveness in maximizing process efficiency and revenue.

Conclusions:

A CT coordinator role can significantly improve the efficiency and financial performance of radiology departments.
Lean methodology (PDCA) is an effective approach for optimizing imaging processes and revenue generation.
