Background

Components of O-RADS

  1. O-RADS Categories

Adnexal masses are categorized by O-RADS into several groups, ranging from benign to malignant. These classifications aid in simplifying communication and offer an intuitive understanding of the dangers that could be connected to a specific mass. Radiologists help with risk stratification by classifying patients based on factors like size, morphology, and vascularity.

  1. Morphological criteria

The O-RADS classification heavily relies on the morphological characteristics of adnexal masses. Features that are looked at closely include solid components, cystic areas, and the presence of septations. Making the distinction between benign and malignant masses is made easier by being aware of certain physical features.

  1. Blood Flow Assessment

An important consideration for determining the likelihood of cancer is vascularization. Doppler ultrasonography is frequently used to assess blood flow in adnexal masses. The O-RADS categorization becomes more accurate and a more precise diagnosis has been rendered possible by the existence and pattern of blood vessels.

There are two complimentary arms to the system:

  1. Magnetic Resonance Imaging (MRI) is a secondary technique that provides for improved specificity,
  2. Ultrasound (US) has high sensitivity.
