Aortic dissection

Aortic dissection (AD) occurs when an injury to the innermost layer of the aorta allows blood to flow between the layers of the aortic wall, forcing the layers apart.

Aortography involves placement of a catheter in the aorta and injection of contrast material while taking X-rays of the aorta.

An autopsy (post-mortem examination, obduction, necropsy, or autopsia cadaverum) is a highly specialized surgical procedure that consists of a thorough examination of a corpse by dissection to determine the cause and manner of death or to evaluate any disease or injury that may be present for research or educational purposes.

Clinical case definition

In epidemiology, a clinical case definition, a clinical definition, or simply a case definition lists the clinical criteria by which public health professionals determine whether a person's illness is included as a case in an outbreak investigation—that is, whether a person is considered directly affected by an outbreak.

Ground truth

Ground truth is a term used in various fields to refer to information provided by direct observation (i.e. empirical evidence) as opposed to information provided by inference.

Information retrieval

Information retrieval (IR) is the activity of obtaining information system resources relevant to an information need from a collection of information resources.

Machine learning

Machine learning is a subset of artificial intelligence in the field of computer science that often uses statistical techniques to give computers the ability to "learn" (i.e., progressively improve performance on a specific task) with data, without being explicitly programmed.

Magnetic resonance angiography

Magnetic resonance angiography (MRA) is a group of techniques based on magnetic resonance imaging (MRI) to image blood vessels.

Magnetic resonance imaging

Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body in both health and disease.

Medical diagnosis

Medical diagnosis (abbreviated Dx or DS) is the process of determining which disease or condition explains a person's symptoms and signs.

Medical error

A medical error is a preventable adverse effect of care, whether or not it is evident or harmful to the patient.

Sensitivity and specificity

Sensitivity and specificity are statistical measures of the performance of a binary classification test, also known in statistics as a classification function.

Statistical hypothesis testing

A statistical hypothesis, sometimes called confirmatory data analysis, is a hypothesis that is testable on the basis of observing a process that is modeled via a set of random variables.

Statistics is a branch of mathematics dealing with the collection, analysis, interpretation, presentation, and organization of data.

Type I and type II errors

In statistical hypothesis testing, a type I error is the rejection of a true null hypothesis (also known as a "false positive" finding), while a type II error is failing to reject a false null hypothesis (also known as a "false negative" finding).
