| PET | PET - Positron emission tomography (PET is a nuclear medicine, functional imaging technique that produces a three-dimensional image of functional processes in the body. The system detects pairs of gamma rays emitted indirectly by a positron-emitting radionuclide (tracer), which is introduced into the body on a biologically active molecule. | |

| MRI | MRI - Magnetic resonance imaging - Magnetic resonance imaging (MRI), nuclear magnetic resonance imaging (NMRI), or magnetic resonance tomography (MRT) is a medical imaging technique used in radiology to investigate the anatomy and physiology of the body in both health and disease. MRI scanners use magnetic fields and radio waves to form images of the body. | |
| MRgFUS | MRgFUS - Magnetic resonance imaging guided high intensity focused ultrasound - MRgFUS uses high intensity focused ultrasonic waves to destroy (ablate) the fibroids under real-time monitoring of the treated tissue. The use of focused ultrasound surgery (FUS) or high intensity focused ultrasound (HIFU) was first discovered in 1942. MRgFUS allows our interventional radiologist to localize, target, monitor, and control the energy delivered by the ultrasound machine to kill the fibroid, without knife or needle. | |
| 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. | |
| MDCT | MDCT - Multidetector Computed Tomography - A form of computed tomography (CT) technology for diagnostic imaging. In MDCT, a two-dimensional array of detector elements replaces the linear array of detector elements used in typical conventional and helical CT scanners. | |
| 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. | |
| LTP | LTP - Laser trabeculoplasty - Laser trabeculoplasty, both argon laser trabeculoplasty(ALT) and selective laser trabeculoplasty (SLT) types, is used to increase aqueous outflow facility through the trabecular meshwork (TM) in order to lower intraocular pressure (IOP) in cases of ocular hypertension and glaucoma. | |
| LR+, LR- | LR+, LR- - Likelihood ratio positive/negative - In evidence-based medicine, likelihood ratios are used for assessing the value of performing a diagnostic test. They use the sensitivity and specificity of the test to determine whether a test result usefully changes the probability that a condition (such as a disease state) exists. Two versions of the likelihood ratio exist, one for positive and one for negative test results. Respectively, they are known as the positive likelihood ratio (LR+, likelihood ratio positive, likelihood ratio for positive results) and negative likelihood ratio (LR–, likelihood ratio negative, likelihood ratio for negative results). | |
| 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). | |
| 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. | |
| IPG | IPG - Neurostimulator/implantable pulse generator - A neurostimulator, also called an implanted pulse generator (IPG) is a battery powered device designed to deliver electrical stimulation to the brain, central and peripheral nervous system. | |
| IIEF-5 | IIEF-5 - International Index of Erectile Function-5 - IIEF-5 scoring:
The IIEF-5 score is the sum of the ordinal responses to the 5 items.
(i) 22-25: No erectile dysfunction
(ii) 17-21: Mild erectile dysfunction
(iii) 12-16: Mild to moderate erectile dysfunction
(iv) 8-11: Moderate erectile dysfunction
(v) 5-7: Severe erectile dysfunction | |
| IGRT | IGRT - Image-guided radiotherapy - Image-guided radiation therapy (IGRT) is the use of frequent imaging during a course of radiation therapy for the purpose of improving the precision and accuracy of the delivery of treatment. | |
| 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. | |
| HRQoL | HRQOL | HRQL | QoL | QOL | HRQoL - Health related quality of life - HRQOL is a broad multidimensional concept that usually includes self-reported measures of physical and mental health. | |
| HIFU | FUS | HIFU - High-intensity focused ultrasound (HIFU, or sometimes FUS for Focused UltraSound) is a medical procedure that applies high-intensity focused ultrasound energy to locally heat and destroy diseased or damaged tissue through ablation. | |
| HTA | Health Technology Assessment (HTA) is a comprehensive, systematic assessment of the background for and the consequences of applying health technology. The purpose of HTA is to improve the basis for decisions about prioritisation and planning in the health area. | |
| HDR | LDR | HDR - High 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). | |
| FES | NMES | Functional electrical stimulation (FES) is a technique that uses electrical currents to activate nerves innervating extremities affected by paralysis resulting from spinal cord injury (SCI), head injury, stroke and other neurological disorders. FES is primarily used to restore function in people with disabilities. It is sometimes referred to as neuromuscular electrical stimulation (NMES). | |
| FN | FP | FN - false negative; FP - false positive - In medical testing, and more generally in binary classification, a false positive is an error in data reporting in which a test result improperly indicates presence of a condition, such as a disease (the result is positive), when in reality it is not, while a false negative is an error in which a test result improperly indicates no presence condition (the result is negative), when in reality it is present. | |
