Radiology is basically defined in the medical world, as a specialty in which medical imaging is being used to identify, diagnose and treat any disorders and diseases that can be seen within the body of the patient who has undergone any imaging techniques and diagnostic procedures. The range of imaging techniques that are being used in radiology includes computed tomography or CT scan for short, X-ray radiography, magnetic resonance imaging or MRI for short, nuclear medicine like PET or positron emission tomography and ultrasound. The primary health care provider or the clinician is the one who are usually asking or requesting, wither routinely or emergently, for a specific imaging procedure, and the individual who carried out the acquisition of the medical images is called as a radiologic technology, which is also known as radiographer, and the person who read or translates such images and does the filing of reports for their diagnosis and findings is called as the reporting radiographer or the diagnostic radiologist. The picture archiving and communication systems or PACS for short, is basically, one of the medical imaging technology where the imaging exams are beings stored, and it can provide convenience of access and economical storage to the images gained from the imaging techniques and procedures made by the radiologists.
In this modern era, most of the hospitals and medical centers and clinics are making use of the different technologies invented by the scientist and inventors that can be provide them the convenience and lighter workload on their duties and responsibilities as professionals in the medical world, and one of the most popular technology, nowadays, is the radiology information system or RIS for short. RIS or radiology information system, is basically one of the products of modernization, and it became the core system for the electronic management of each and every imaging departments. Typically, RIS is being used by the hospitals as their computer database that can provide them the help they need in distributing, tracking and manipulating the imagery and data of their patients, and because of that it is considered as an electronic health record system specifically designed for the field of radiology. The specific system may work by integrating and merging a variety of functions into a single system of comprehension and with that is can eliminate and avoid any occurrence of redundancies and can increase the efficiency and accessibility of a clinic and hospital. There are several features that are being supported by the RIS and that includes patient list management, result entry, patient registration and scheduling, interface with modality through work-list, radiology department workflow management, request and document scanning, reporting and printout, result delivery such as faxing and e-mailing of medical or clinical reports, interactive documents, patient tracking, modality and material management, technical files creation, PACS workflow, appointment booking, custom report creation, rule engines and billing. The benefits that the health care provider and the hospital or clinic may obtain upon using the RIS includes obtaining a more accurate diagnoses and better health outcomes, better coordination of patient care, higher quality of patient care, and higher cost of savings and efficiency.
