Study Notes

Radiology Workflow Overview

Workflow in radiology refers to the automated processes involved in examinations, from order entry to report transcription.
The process includes passing documents and information among participants according to procedural rules.

Film-Based Workflow

Traditional radiology departments utilized film and chemical processing with specific designs like pass boxes and darkrooms.
Advances in chemical processing reduced development times from several minutes to under 60 seconds.
Film still required manual handling, including delivery to radiologists and making copies for referring physicians.

Steps in Radiology Workflow

Order Entry: Orders can be paper prescriptions or placed electronically in the Radiology Information System (RIS), which creates a requisition with essential patient information.
Technologist Preparation: The technologist prepares the examination room, verifies patient details, and reviews medical history.
Film Processing: Examinations are performed, films processed, and critiques conducted by the technologist, including repeated exposures when necessary.
Radiologist Review: Radiologists read films and dictate reports which are then transcribed into the RIS.
Report Finalization: Reviews, corrections, and signatures on reports occur before they are printed and filed or sent to ordering physicians.

Picture Archiving and Communication System (PACS)

PACS is a digital imaging technology used for storing and transmitting electronic images and reports securely.
Eliminates manual handling of films, allowing for off-site storage and access from anywhere via PACS software.
As digital images grow in volume, PACS aids in data management and analytics.

PACS in Various Departments

Initially used primarily by radiologists, PACS is now integrated into departments like nuclear medicine, cardiology, oncology, and dermatology.
Provides clinicians with digital access to patient images and history, improving care and reducing errors.

Development and Standards

The effectiveness of PACS is tied to DICOM (Digital Imaging and Communications in Medicine), a standard developed for medical imaging.
In 1983, the American College of Radiology (ACR) and the National Electrical Manufacturers Association (NEMA) collaborated to create imaging standards.

PACS Architecture

Comprises four components: imaging machines, secure networks, workstations/mobiles for viewing, and electronic archives for storage.
Has significant benefits including remote access for multiple clinicians and interface capabilities with electronic health management systems.

Medical Imaging Informatics

A branch of biomedical informatics focusing on digital medical images.
Involves image generation, manipulation, management, and integration with patient records for comprehensive analysis and interpretation.

Importance of Medical Imaging

Critical for diagnosis, treatment planning, image-guided treatments, monitoring response to therapy, prognosis estimation, medical communication, education, and research.

Historical Progression of Medical Imaging

1980s: Introduction of computed radiography (CR), MRI, CT, and ultrasound technologies, along with digital storage and networking.
Late 1980s: Integration of imaging systems like PACS, establishment of DICOM standards.
Early 1990s to Present: Increased integration of HIS/RIS/PACS systems, workflow automation, developments in imaging informatics.

Energy Sources for Medical Imaging

Light, X-rays (used in fluoroscopy and CT scans), ultrasound (ultrasonography), and nuclear magnetic resonance (MRI and PET scans) are key technologies for imaging.
