| CE-CCT | CE-CCT - Contrast enhanced coronary computed tomography - (CECT) Contrast agents are used during contrast enhanced computed (or computerized) tomography examinations to highlight specific tissues and parts of the body. | |
| CBCT | CBCT - Cone-beam computed tomography - Cone beam computed tomography (or CBCT, also referred to as C-arm CT, cone beam volume CT, or flat panel CT) is a medical imaging technique consisting of X-ray computed tomography where the X-rays are divergent, forming a cone. | |
| CAD | IHD | CAD - Coronary artery disease - Coronary artery disease (CAD), also known as ischemic heart disease (IHD), atherosclerotic heart disease, atherosclerotic cardiovascular disease, and coronary heart disease, is a group of diseases that includes: stable angina, unstable angina, myocardial infarction, and sudden coronary death. | |
| CAD | CAD - Computer-aided detection | computer-aided diagnosis - CAD is a technology designed to decrease observational oversights—and thus the false negative rates—of physicians interpreting medical images. | |
| BSCVA | BSCVA - Best spectacle-corrected visual acuity. Visual acuity (VA) is acuteness or clearness of vision. It depends on optical and neural factors, i.e., (i) the sharpness of the retinal focus within the eye, (ii) the intactness and functioning of the retina, and (iii) the sensitivity of the interpretative faculty of the brain. | |
| BIS | Bispectral index (BIS) is one of several technologies used to monitor depth of anesthesia. BIS monitors are intended to replace or supplement Guedel's classification system for determining depth of anesthesia. | |
| AUC | AUROC | AUC - Area under the curve - When using normalized units, the area under the curve (often referred to as simply the AUC, or AUROC) is equal to the probability that a classifier will rank a randomly chosen positive instance higher than a randomly chosen negative one (assuming 'positive' ranks higher than 'negative') | |
| APHAB | APHAB - Abbreviated Profile of Hearing Aid Benefit - The APHAB is a 24-item self-assessment inventory in which patients report the amount of trouble they are having with communication or noises in various everyday situations. | |
| APD | APD - Automated Peritoneal Dialysis - a treatment for patients with severe chronic kidney disease. The process uses the patient's peritoneum in the abdomen as a membrane across which fluids and dissolved substances (electrolytes, urea, glucose, albumin and other small molecules) are exchanged from the blood. | |
| AIDR | AIDR - Artificial intervertebral disc replacement - Artificial disc replacement (ADR), or total disc replacement (TDR), is a type of arthroplasty. It is a surgical procedure in which degenerated intervertebral discs in the spinal column are replaced with artificial devices in the lumbar (lower) or cervical (upper) spine. | |
| AHI | AI | AHI - Apnoea/Hypopnoea index, Apnoea-Hypopnoea index | AI - Apnoea index - The Apnea–Hypopnea Index or Apnoea–Hypopnoea Index (AHI) is an index used to indicate the severity of sleep apnea. It is represented by the number of apnea (pause in breathing) and hypopnea (disorder which involves episodes of overly shallow breathing) events per hour of sleep. | |
| AF | A-fib | AF | A-fib - Atrial fibrillation - an abnormal heart rhythm characterized by rapid and irregular beating. The disease increases the risk of heart failure, dementia, and stroke. | |
| ABBR | ABBR - Abbreviation - Description | — |
