Marjorie Dalgarno
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. Biography Dalgarno was born in Sydney in 1901 and studied medicine at the University of Sydney's Women's College. She graduated in 1925 and was hired as a resident medical officer at the Royal Prince Alfred Hospital, where she worked in the radiology department. After marrying Harold McCredie, a general practitioner, in 1928, she established a radiological practice based out of their home in Campsie. Her home practice included an x-ray machine installed in the dining room and a laundry that was converted into a darkroom for developing x-ray films. In 1939, she began working at the Rachel Forster Hospital in Redfern and the Renwick Hospital for Infants in Summer Hill; she also worked at the Western Suburbs Hospital in Croydon du ...

Radiologist
Radiology ( ) is the medical discipline that uses medical imaging to diagnose diseases and guide their treatment, within the bodies of humans and other animals. It began with radiography (which is why its name has a root referring to radiation), but today it includes all imaging modalities, including those that use no electromagnetic radiation (such as ultrasonography and magnetic resonance imaging), 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. The modern practice of radiology involves several different healthcare professions working as a team. The radiologist is a medical doctor who has completed the appropriate post-graduate training and interprets medical images, communicates these findings to other physicians by m ...

Redfern, New South Wales
Redfern is an inner-city suburb of Sydney located 3 kilometres south of the Sydney central business district and is part of the local government area of the City of Sydney. Strawberry Hills is a locality on the border with Surry Hills. The area experienced the process of gentrification and is subject to extensive redevelopment plans by the state government, to increase the population and reduce the concentration of poverty in the suburb and neighbouring Waterloo (see Redfern-Eveleigh-Darlington). History The suburb is named after surgeon William Redfern, who was granted of land in this area in 1817 by Lachlan Macquarie. He built a country house on his property surrounded by flower and kitchen gardens. His neighbours were Captain Cleveland, an officer of the 73rd regiment, who built Cleveland House and John Baptist, who ran a nursery and seed business. Sydney's original railway terminus was built in Cleveland Paddocks and extended from Cleveland Street to Devonshire Street a ...

Sydney ( ) is the capital city of the state of New South Wales, and the most populous city in both Australia and Oceania. Located on Australia's east coast, the metropolis surrounds Sydney Harbour and extends about towards the Blue Mountains to the west, Hawkesbury to the north, the Royal National Park to the south and Macarthur to the south-west. Sydney is made up of 658 suburbs, spread across 33 local government areas. Residents of the city are known as "Sydneysiders". The 2021 census recorded the population of Greater Sydney as 5,231,150, meaning the city is home to approximately 66% of the state's population. Estimated resident population, 30 June 2017. Nicknames of the city include the 'Emerald City' and the 'Harbour City'. Aboriginal Australians have inhabited the Greater Sydney region for at least 30,000 years, and Aboriginal engravings and cultural sites are common throughout Greater Sydney. The traditional custodians of the land on which modern Sydney stands are th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Screening (medicine)
Screening, in medicine, is a strategy used to look for as-yet-unrecognised conditions or risk markers. This testing can be applied to individuals or to a whole population. The people tested may not exhibit any signs or symptoms of a disease, or they might exhibit only one or two symptoms, which by themselves do not indicate a definitive diagnosis. Screening interventions are designed to identify conditions which could at some future point turn into disease, thus enabling earlier intervention and management in the hope to reduce mortality and suffering from a disease. Although screening may lead to an earlier diagnosis, not all screening tests have been shown to benefit the person being screened; overdiagnosis, misdiagnosis, and creating a false sense of security are some potential adverse effects of screening. Additionally, some screening tests can be inappropriately overused. For these reasons, a test used in a screening program, especially for a disease with low incidence, must ...

Mammogram
Mammography (also called mastography) is the process of using low-energy X-rays (usually around 30 kVp) 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. As with all X-rays, mammograms use doses of ionizing radiation to create images. These images are then analyzed for abnormal findings. It is usual to employ lower-energy X-rays, typically Mo (K-shell X-ray energies of 17.5 and 19.6 keV) and Rh (20.2 and 22.7 keV) than those used for radiography of bones. Mammography may be 2D or 3D (tomosynthesis), depending on the available equipment and/or purpose of the examination. Ultrasound, ductography, positron emission mammography (PEM), and magnetic resonance imaging (MRI) are adjuncts to mammography. Ultrasound is typically used for further evaluation of masses found on mammography or palpable masses that may or may not be seen on mammo ...

Breast Lump
A breast mass, also known as a breast lump, is a localized swelling that feel different from the surrounding tissue. Breast pain, nipple discharge, or skin changes may be present. Concerning findings include masses that are hard, do not move easily, are of an irregular shape, or are firmly attached to surrounding tissue. Causes include fibrocystic change, fibroadenomas, breast infection, galactoceles, and breast cancer. Breast cancer makes up about 10% of breast masses. Diagnosis is typically by examination, medical imaging, and tissue biopsy. Tissue biopsy is often by fine needle aspiration biopsy. Repeated examination may be required. Treatment depends on the underlying cause. It may vary from simple pain medication to surgical removal. Some causes may resolve without treatment. Breast masses are relatively common. It is the most common breast complaint with the women's concern generally being that of cancer. Types Cysts and abscesses A breast cyst is a non-cancer ...

Macquarie Street, Sydney
Macquarie Street is a street in the central business district of Sydney in New South Wales, Australia. Macquarie Street extends from Hyde Park at its southern end to the Sydney Opera House at its northern end. Apart from connecting these two major landmarks, the key government institutions of the state of New South Wales are all located on this street. History Macquarie Street is named after Lachlan Macquarie, an early Governor of New South Wales (in office 1810–1821). In the years since its founding in 1788, Sydney had developed organically, and by the early 1800s was lacking in major public buildings, and had a complex network of narrow streets. The supply of drinking water and waste management was also becoming an issue. Governor Macquarie initiated the construction of Sydney's first public buildings of any real permanence and set the boundaries of Sydney's grid of streets. With Circular Quay as the focus of this new civic scheme, Macquarie Street marked its eastern bou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
