Lecture 2 Pretest

Attribution bias:

  1. Reflects the undue influence that an initial interpretation has on the evaluation of subsequently collected information
  2. Refers to overestimating the likelihood of a particular disease due to the undesirability of an adverse outcome from a failure to diagnose that disease
  3. Refers to when specific characteristics are attributed to a person or thing simply because it belongs to a certain class
  4. Represents when radiologists have a heightened awareness of commonly missed or misinterpreted findings, which may lead to overcalling known types of errors

Blind spot bias:

  1. Refers to when specific characteristics are attributed to a person or thing simply because it belongs to a certain class
  2. Results from a tendency to be influenced by how a question is asked or how a problem is presented
  3. Refers to the tendency for diagnostic assessments to be unduly influenced by easily recalled experiences
  4. Represents when radiologists have a heightened awareness of commonly missed or misinterpreted findings, which may lead to overcalling known types of errors

Regret bias:

  1. Reflects the undue influence that an initial interpretation has on the evaluation of subsequently collected information
  2. Refers to overestimating the likelihood of a particular disease due to the undesirability of an adverse outcome from a failure to diagnose that disease
  3. Refers to the tendency for diagnostic assessments to be unduly influenced by easily recalled experiences
  4. Represents the influence that one radiologist’s judgment can exert on the diagnostic thinking of another radiologist

A 76 year old man with sarcoidosis and unexplained weight loss has an unenhanced CT scan (see images). What is the most likely diagnosis?

Average attenuation value (AV) shown in ROI
  1. Perigastric hematoma
  2. Gastric cancer
  3. Lymphoma
  4. Abscess

Which of the following is an intervention that can mitigate framing bias?

  1. Seek out a more thorough clinical history from the electronic medical record or directly from the ordering provider
  2. Review prior radiologist report after reviewing prior imaging and rendering an interpretation
  3. Reference sources of information beyond one’s personal experience, including relevant peer-reviewed publications
  4. Be mindful of known combinations of injuries
