Radiology Practice Test

What is the primary function of a PACS in radiology?

1. To create 3D models for surgery

2. To store, retrieve, and share medical images digitally

3. To analyze blood samples

4. To perform physical examinations

The correct answer is: To store, retrieve, and share medical images digitally

The primary function of a PACS, or Picture Archiving and Communication System, in radiology is to store, retrieve, and share medical images digitally. This system enhances the efficiency and accessibility of radiological data, allowing healthcare professionals to quickly access and review images from various modalities such as X-rays, CT scans, and MRIs. By digitizing images, PACS eliminates the need for physical storage of film and makes it easier to share images with other specialists or departments, facilitating collaboration and improving patient care. The system also allows for better organization and indexing of images, making it simpler to track patient records over time. Other options, while they relate to healthcare and diagnostics, do not fall under the core functions of a PACS. For instance, creating 3D models for surgery is a separate process that may utilize images obtained from PACS but is not a primary function of the system itself. Similarly, analyzing blood samples and performing physical examinations are related to different areas of medical practice and do not pertain to the digital management of radiological images.
