A picture archiving and communication system (PACS) is a medical imaging technology which provides economical storage and convenient access to images from multiple modalities. Electronic images and reports are transmitted digitally via PACS; this eliminates the need to manually file, retrieve, or transport film jackets, the folders used to store and protect X-ray film. The universal format for PACS image storage and transfer is DICOM. Non-image data, such as scanned documents, may be incorporated using consumer industry standard formats like PDF, once encapsulated in DICOM. A PACS consists of four major components: The imaging modalities such as X-ray plain film (PF), computed tomography (CT) and magnetic resonance imaging (MRI), a secured network for the transmission of patient information, workstations for interpreting and reviewing images, and archives for the storage and retrieval of images and reports. Combined with available and emerging web technology, PACS has the ability to deliver timely and efficient access to images, interpretations, and related data. PACS reduces the physical and time barriers associated with traditional film-based image retrieval, distribution, and display.
Radiology is the medical specialty that uses medical imaging to diagnose diseases and guide their treatment, within the bodies of humans and other animals. It began with radiography, but today it includes all imaging modalities, including those that use no electromagnetic radiation, as well as others that do, such as computed tomography (CT), fluoroscopy, and nuclear medicine including positron emission tomography (PET). Interventional radiology is the performance of usually minimally invasive medical procedures with the guidance of imaging technologies such as those mentioned above.
Mammography is the process of using low-energy X-rays to examine the human breast for diagnosis and screening. The goal of mammography is the early detection of breast cancer, typically through detection of characteristic masses or microcalcifications.
Teleradiology is the transmission of radiological patient images from procedures such as x-rays photographs, Computed tomography (CT), and MRI imaging, from one location to another for the purposes of sharing studies with other radiologists and physicians. Teleradiology allows radiologists to provide services without actually having to be at the location of the patient. This is particularly important when a sub-specialist such as an MRI radiologist, neuroradiologist, pediatric radiologist, or musculoskeletal radiologist is needed, since these professionals are generally only located in large metropolitan areas working during daytime hours. Teleradiology allows for specialists to be available at all times.
The American College of Radiology (ACR), founded in 1923, is a professional medical society representing nearly 40,000 diagnostic radiologists, radiation oncologists, interventional radiologists, nuclear medicine physicians and medical physicists.
Radiographers, also known as radiologic technologists, diagnostic radiographers and medical radiation technologists are healthcare professionals who specialise in the imaging of human anatomy for the diagnosis and treatment of pathology. Radiographers are infrequently, and almost always erroneously, known as x-ray technicians. In countries that use the title radiologic technologist they are often informally referred to as techs in the clinical environment; this phrase has emerged in popular culture such as television programmes. The term radiographer can also refer to a therapeutic radiographer, also known as a radiation therapist.
Established in 1964, the Aga Khan Hospital, Dar es Salaam is a 170-bed multispecialty hospital. The hospital provides general medical services, specialist clinics and diagnostic services. It serves as a hub for several clinics around the city. It is also part of the Aga Khan Health Services international referral system, with links to the Aga Khan Hospital, Nairobi and the Aga Khan University Hospital, Karachi.
BI-RADS is an acronym for Breast Imaging-Reporting and Data System, a quality assurance tool originally designed for use with mammography. The system is a collaborative effort of many health groups but is published and trademarked by the American College of Radiology (ACR).
Computer-aided detection (CADe), also called computer-aided diagnosis (CADx), are systems that assist doctors in the interpretation of medical images. Imaging techniques in X-ray, MRI, Endoscopy, and ultrasound diagnostics yield a great deal of information that the radiologist or other medical professional has to analyze and evaluate comprehensively in a short time. CAD systems process digital images or videos for typical appearances and to highlight conspicuous sections, such as possible diseases, in order to offer input to support a decision taken by the professional.
Kakarla Subba Rao was an Indian radiologist who served as the first director of Nizam's Institute of Medical Sciences, Hyderabad. For his contributions to the field of medicine, Rao was conferred Padma Shri in 2000, the fourth highest civilian award by the Government of India. He was also the founder and president of the Telugu Association of North America.
Daniel B. Kopans, MD, FACR is a radiologist specializing in mammography and other forms of breast imaging.
Physician self-referral is a term describing the practice of a physician ordering tests on a patient that are performed by either the referring physician himself or a fellow faculty member from whom he receives financial compensation in return for the referral. Examples of self-referral include an internist performing an EKG, a surgeon suggesting an operation that he himself would perform, and a physician ordering imaging tests that would be done at a facility he owns or leases.
Stafford Leak Warren was an American physician and radiologist who was a pioneer in the field of nuclear medicine and best known for his invention of the mammogram. Warren developed the technique of producing stereoscopic images of the breast with X-rays while working in the Department of Radiology at the University of Rochester School of Medicine.
Global radiology, a subspecialty of diagnostic radiology, comprises the study and practice of improving access to radiology resources in poor and developing countries, and addressing global health inequities through the application of radiology. Similar to the fields of public health and global health, global radiology draws on and encourages collaboration with nonmedical specialties relevant to disease patterns and the provision of medical services, including economic development, biomedical technology, engineering and social sciences.
Ulana Nadia Suprun is a Ukrainian-American physician, activist, and philanthropist who served as the acting Minister of Healthcare from 2016 to 2019. Prior to her government career, Suprun served as Director of Humanitarian Initiatives for the Ukrainian World Congress.
Fiona Jane Gilbert is a Scottish radiologist and academic.
Rosalind Ambrose is a Vincentian radiologist who has been instrumental in the development of the field in her country and throughout the Caribbean region. She served as Director of Education for the Kingstown Medical College, was a founding member of the Caribbean Society of Radiologists, and was President of the St. Vincent and the Grenadines Medical Association from 2001 to 2010.
Marjorie Clare Dalgarno (1901–1983) was an Australian radiologist and a pioneer of mammography. She performed the first mammogram in Australia at the Rachel Forster Hospital and demonstrated the benefits of mammography as a breast cancer screening tool.
Henrietta Elizabeth Banting or “Lady Banting” was a Canadian physician and the second wife of Sir Frederick Banting. Banting was the Director of Women's College Hospital's Cancer Detection Clinic from 1958-1971. While working at the Cancer Detection Clinic, she conducted a research study on mammography to measure its effectiveness as a diagnostic tool for breast cancer.
Elizabeth Margaret Forbes was a Canadian radiologist. Forbes was the Chief of Radiology at Toronto's Women's College Hospital (WCH) from 1955 to 1975. She is remembered for co-authoring “one of the first Canadian papers on mammography” with WCH's Henrietta Banting.
