CT Colonography Reporting and Data System (C-RADS)

In 2005, the CT Colonography Reporting and Data System (C-RADS) was established to provide a means of classifying findings of CT colonography (CTC) and of applying the advantages of structured reporting to the setting of colorectal cancer screening.

Gynecologic Imaging Reporting and Data System (GI-RADS)

Transvaginal ultrasound is the main reference technique in the evaluation of adnexal masses. Based on the Breast Imaging Reporting and Data System (BIRADS) classification Amor et al. suggested adapting this system to gynecologic ultrasound for the evaluation of adnexal masses: Gynecologic Imaging Reporting and Data System (GI-RADS) and based on recognition patterns and criteria recommended by the IOTA group.

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.

Criteria for Neurosurgical or Neuroradiologic Intervention for Mold Infections of the Central Nervous System (CNS)

The clinical characteristics of mold infections of the CNS warrant assessment for possible biopsy and neurosurgical intervention. A definitive diagnosis almost invariably requires a biopsy, with prompt inspection of the specimen by means of wet-mount preparation with calcofluor white stain, culture, and histologic analysis (with Gomori methenamine silver stain and periodic acid–Schiff stain). In situ hybridization and immunohistochemical analysis may be helpful if cultures of biopsy specimens are negative.

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.

Cierny-Mader Staging System for Long Bone Osteomyelitis

Cierny and Mader classified osteomyelitis based on the affected portion of the bone, the physiologic status of the host and the local environment. This classification lends itself to the treatment and prognosis of osteomyelitis; stage 1 (medullary osteomyelitis) can usually be treated with antibiotics alone, while stages 2, 3 and 4 (superficial, localized and diffuse osteomyelitis) usually require aggressive debridement, antimicrobial therapy and subsequent orthopedic reconstruction.

The Rockall Scoring System

The Rockall score is an established and useful system to assess upper gastrointestinal bleeding (UGIB). The Rockall system has been shown to represent an accurate and valid predictor of rebleeding and death, performing better in the latter than in the former. Rockall scores are designed to combine information such as the subject’s age, occurrence of shock assessed from systolic blood pressure readings and pulse rate, presence and severity of comorbid conditions, diagnosis and endoscopic stigmata of recent bleeding.
