| RD | RD - Retinal detachment - Retinal detachment is a disorder of the eye in which the retina peels away from its underlying layer of support tissue. Initial detachment may be localized or broad, but without rapid treatment the entire retina may detach, leading to vision loss and blindness. | |
| LDR | HDR | LDR - Low dose rate - Brachytherapy is a type of radiotherapy, or radiation treatment, offered to certain cancer patients. There are two types of brachytherapy – high dose-rate (HDR) and low dose-rate (LDR). | |
| RM3 | RM3 - Renal Preservation System - Perfusion Device for Pulsatile Kidney Preservation. | |
| MIBI scan | INN | MIBI scan - Tc-hexakis-2-methoxy isobutyl isonitrate scan - myocardial perfusion scan - Technetium (99mTc) sestamibi (INN) (commonly sestamibi; USP: technetium Tc 99m sestamibi; trade name Cardiolite) is a pharmaceutical agent used in nuclear medicine imaging. | |
| IPL | IPL - Intense pulsed light - Intense pulsed light, commonly abbreviated as IPL, is a technology used by cosmetic and medical practitioners to perform various skin treatments for aesthetic and therapeutic uses including hair removal, photorejuvenation, and treatment of dermatologic diseases. | |
| ICD | AICD | ICD - Implantable cardioverter defibrillator - An implantable cardioverter-defibrillator (ICD) or automated implantable cardioverter defibrillator (AICD) is a device implantable inside the body, able to perform both cardioversion, defibrillation and pacing of the heart. | |
| PPV | PPV - Positive predictive value - The positive and negative predictive values (PPV and NPV respectively) are the proportions of positive and negative results in statistics and diagnostic tests that are true positive and true negative results | |
| OSAHS | OSAHS - Obstructive sleep apnoea/hypopnoea syndrome - OSAHS is a syndrome associated with characteristic clinical picture and specific abnormalities on assessment. In OSAHS, there is repetitive collapse of the upper airway, which may be either partial or total resulting in hypopnea or apnea, respectively; during sleep, it occurs more than five times per hour (apnea–hypopnea index (AHI)). | |
| DOR | DOR - Diagnostic odds ratio - In medical testing with binary classification, the diagnostic odds ratio is a measure of the effectiveness of a diagnostic test. It is defined as the ratio of the odds of the test being positive if the subject has a disease relative to the odds of the test being positive if the subject does not have the disease. | |
| PECLA | iLA | pECLA | PECLA - Pumpless extracorporeal lung assist - (i) Pumpless interventional lung assist (iLA) is used in patients with acute respiratory distress syndrome (ARDS) aimed at improving extracorporeal gas exchange with a membrane integrated in a passive arteriovenous shunt. (ii) pECLA is a promising alternative compared with conventional pump-driven systems for patients with ARDS and brain injury, since the pECLA system has minor restrictions, limitations and side effects. | |
| 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. | |
| MAS | MAS - Mandibular advancement splints - A mandibular splint or mandibular advancement splint (MAS) is a device worn in the mouth that is used to treat obstructive sleep apnea (OSA) and snoring. These devices are also known as mandibular advancement devices, sleep apnea oral appliances, Oral Airway Dilators and sleep apnea mouth guards. | |
| EBCT | EBT | EBCT - Electron beam computed tomography - Electron beam tomography (EBT) is a specific form of computed tomography (CAT or CT) in which the X-ray tube is not mechanically spun in order to rotate the source of X-ray photons. This different design was explicitly developed to better image heart structures which never stop moving, performing a complete cycle of movement with each heart beat. | |
| PICC | PICC - Peripherally Inserted Central Venous Catheter - PICC or PIC line) is a form of intravenous access that can be used for a prolonged period of time (e.g. for long chemotherapy regimens, extended antibiotic therapy, or total parenteral nutrition). | |
| NPV | NPV - Negative predictive value - The positive and negative predictive values (PPV and NPV respectively) are the proportions of positive and negative results in statistics and diagnostic tests that are true positive and true negative results. | |
| QOL | QoL | QoL - Quality of life - Quality of life (QOL) is the general well-being of individuals and societies. QOL has a wide range of contexts, including the fields of international development, healthcare, politics and employment. | |
| YAG-laser | YAG-laser - Yttrium aluminium garnet-laser - Yttrium aluminium garnet (YAG, Y<sup>3</sup>Al<sup>5</sup>O<sup>12</sup>) is a synthetic crystalline material of the garnet group. It is also one of three phases of the yttrium-aluminium composite, the other two being yttrium aluminium monoclinic (YAM, Y<sup>4</sup>Al<sup>2</sup>O<sup>9</sup>) and yttrium aluminium perovskite (YAP, YAlO<sup>3</sup>). YAG is commonly used as a host material in various solid-state lasers. | |
| TN | TP | TN | TP - True-negative | True-positive - True positive = correctly identified; False positive = incorrectly identified; True negative = correctly rejected ; False negative = incorrectly rejected - see also sensitivity and specificity (weblink and video) | |
| RFA | RFA - Radiofrequency ablation - (RFA) is a medical procedure in which part of the electrical conduction system of the heart, tumor or other dysfunctional tissue is ablated using the heat generated from high frequency alternating current (in the range of 350–500 kHz). | |
