Differences Between RIS, CIS, PACS and DICOM

There are many technical terms that are widely used among medical professionals using medical technology. 4 of the mostly used terms are RIS, IS, PACS and DICOM. Here are a short overview of all of these terms for you.


1. PACS – Picture Archive and Communication System

It stands for Picture Archive and Communication System. PACS is used for storing imaging data and other relevant files. There can be 2D and 3D images. It is widely used in radiology and healthcare sector where the patient related images and data is stored.

The purpose of PACS is to allow the medical staff and doctors to maintain and store medical images and restore them whenever needed. In short, this is just an archive system where images and other data is stored for records and later use. The paperwork and documented records are hard to manage and maintain in this time and age of the latest technology so it offers a simple solution for data keeping.

2. RIS – Radiology Information System

RIS stands for Radiology Information System. It is of great importance and has a wide range of uses in medical and healthcare sector. From billing to record keeping and maintaining imaging data, RIS imaging software is widely used in radiology departments. It is different than others in multiple ways as it allows to maintain bills, patient record and data as well as offer a simple solution for documentation.

RIS imaging software is the need of every radiology department because most of the hospitals have now adopted RIS. If a hospital is not using this system, they will not be able to deal with the workload, number of patients, maintain their data and provide them with reports immediately. The RIS system also helps when it comes to referring patients to new doctors.

3. CIS – Clinical Information System


CIS stands for Clinical Information System. The doctors and clinical department staff often use this word. It contains a number of software solutions including RIS, EHR, and EMR. CIS is helpful when it comes to tie all the data together in one place and accessing the required information when needed. Different service providers have software solutions for CIS.

This integrated patient information system has a great and increasing use in the healthcare. Hospitals and clinics are getting rid of documents and paperwork. They don’t want to check all the records and files when they have to get data of a patient. So this software based system facilitates the staff as well as patients who get their reports and files in a short time.

4. DICOM – Digital Imaging and Communications in Medicine


Digital Imaging and Communications in Medicine is the full form of DICOM. DICOM is another way to store imaging data and files. There are systems that are working without digital imaging but now they need DICOM because it can produce better quality, accurate and precise images for disease detection and treatment of the patients.

The doctors send patients to radiology departments for DICOM where the staff gets reports of the patients. These reports are sent to the doctors or physicians who can understand what the issue is and when the patient should get their check-ups just like is just like RIS imaging software. In short, DICOM allows doctors to diagnose the diseases in more effective way to provide patients with the right kind of treatment.

Cloud based medical record storage technology has made a tremendous revolution to the medical technology.
