Diagnostic Services

Diagnostic Services facilitates the provision of timely, cost-effective, and high quality diagnostic care in safe and secure environments. It includes the clinical services of Pathology and Laboratory Medicine, Radiology, and Nuclear Medicine . These services function in the settings of ambulatory care, acute care, mental health, geriatric and rehabilitative care. Facility based diagnostic service employees include physicians, nurses, technicians, technologists, administrators, as well as program assistants and analysts. Combining these diagnostic services and employees into an interdisciplinary group facilitates the sharing of knowledge and permits uniformity of practices and policies.




Pathology is a significant field in modern medical diagnosis and medical research, concerned mainly with the causal study of disease, whether caused by pathogens or non-infectious physiological disorder. The word pathology itself may be used broadly to refer to the study of disease in general, incorporating a wide range of bioscience research fields and medical practices. However, when used in the context of modern medical treatment, the term is often used in a more narrow fashion to refer to processes and tests which fall within the contemporary medical field of "general pathology," an area which includes a number of distinct but inter-related medical specialties that diagnose disease, mostly through analysis of tissue, cell, and body fluid samples. Idiomatically, "a pathology" may also refer to the predicted or actual progression of particular diseases (as in the statement "the many different forms of cancer have diverse pathologies"), and the affix path is sometimes used to indicate a state of disease in cases of both physical ailment and psychological conditions. A physician practicing pathology is called a pathologist. As a field of general inquiry and research, pathology addresses four components of disease: cause, mechanisms of development , structural alterations of cells (morphologic changes), and the consequences of changes (clinical manifestations). In common medical practice, general pathology is mostly concerned with analyzing known clinical abnormalities that are markers or precursors for both infectious and non-infectious disease and is conducted by experts in one of two major specialties, anatomical pathology and clinical pathology. Further divisions in specialty exist on the basis of the involved sample types (comparing, for example, cytopathology, hematopathology, and histopathology), organs (as in renal pathology), and physiological systems (oral pathology), as well as on the basis of the focus of the examination (as with forensic pathology)


B-scan another method used for ocular assessment via ultrasound. It can be performed directly on the anesthetized eye. In cases of trauma or in children, B-scan can be performed over the eyelid with coupling jelly. Measurements derived from B-scan include visualization of the lesion, including anatomic location, shape, borders, and size. It can be used for a detection of a wide-range of pathological structures, including retinal or choroidal detachment, foreign bodies, calcium, and tumors . Echoes in B-scan are converted to dots with brightness intensity that is proportional to the echo amplitude. For example, high amplitude echoes appear as hyperechoic (white), and absent echoes appear black (anechoic). It is especially useful
in imaging of tumors of the anterior orbit, myositis with associated EOM tendon thickening, and visualization of the superior ophthalmic vein in carotid cavernous fistulas.
