Prostate Imaging Reporting And Data System (PI-RADS)

PI-RADS is designed to improve focal lesion detection, localization, characterization, and risk stratification in patients with suspected cancer and consists of technical recommendation for MRI acquisition and a scoring system for image interpretation. PI-RADS uses a scale of 1–5 to report the overall probability of clinically significant prostate cancer on multiparametric MRI (mpMRI). The use of PI-RADS is limited to treatment naive patients and it should not be used for staging, assessment of treatment outcome, recurrence, or progression during surveillance.

Kurtzke’s Expanded Disability Status Scale (EDSS)

The Expanded Disability Status Scale (EDSS), an accepted method of quantifying disability in Multiple Sclerosis (MS) consists of an eight-function system scale monitoring motor, sensory, cerebellar, brain stem, visual, bowel and bladder, pyramidal and other functions.

Criteria for Grading Hepatic Encephalopathy

Grading of hepatic encephalopathy categorizes it in clinical stages of stepwise worsening. The description of each grade varies somewhat in the literature, but differences between adjacent grades are clear enough to be helpful in clinical practice, although neurologic descriptors are sparse. One study showed that for patients who become comatose, the Full Outline of Unresponsiveness (FOUR) score is more discriminating than the West Haven grading system because it includes brain-stem and respiration assessment, which are not further differentiated in the West Haven system.

Alvarado Score for Acute Appendicitis

The use of the Alvarado scoring system, which includes clinical examination findings and laboratory values, is helpful in ruling out appendicitis. Scores range from 1 to 10, with higher scores indicating a greater risk of appendicitis. When the score is less than 4, appendicitis is uncommon, and imaging and other interventions can be avoided.

Modified Khorana Risk Score for Prediction of Venous Thromboembolic Events (VTE) in Patients with Cancer

Risk assessment tools can incorporate multiple variables to identify patients or subpopulations at risk for events. A recently developed risk score can identify cancer patients at high risk for VTE using a combination of easily available clinical and laboratory variables.

Diagnostic Scoring System for Disseminated Intravascular Coagulation (DIC)

Disseminated intravascular coagulation is a clinicopathological diagnosis of a disorder that is defined by the International Society on Thrombosis and Hemostasis (ISTH) as “an acquired syndrome characterized by the intravascular activation of coagulation with loss of localization arising from different causes”. This condition typically originates in the microvasculature and can cause damage of such severity that it leads to organ dysfunction. It can be identified on the basis of a scoring system developed by the ISTH.
