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

• Attribution bias refers to when specific characteristics are attributed to a person or thing simply because it belongs to a certain class.
• Anchoring bias reflects the undue influence that an initial interpretation has on the evaluation of subsequently collected information
• Regret bias refers to overestimating the likelihood of a particular disease due to the undesirability of an adverse outcome from a failure to diagnose that disease
• Blind spot bias 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*

• Blind spot bias represents when radiologists have a heightened awareness of commonly missed or misinterpreted findings, which may lead to overcalling known types of errors
• Attribution bias refers to when specific characteristics are attributed to a person or thing simply because it belongs to a certain class
• Framing bias results from a tendency to be influenced by how a question is asked or how a problem is presented
• Availability bias refers to the tendency for diagnostic assessments to be unduly influenced by easily recalled experiences

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

• Regret bias refers to overestimating the likelihood of a particular disease due to the undesirability of an adverse outcome from a failure to diagnose that disease
• Anchoring bias reflects the undue influence that an initial interpretation has on the evaluation of subsequently collected information
• Regret bias refers to overestimating the likelihood of a particular disease due to the undesirability of an adverse outcome from a failure to diagnose that disease
• Alliterative bias 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?

1. Perigastric hematoma
2. Gastric cancer
3. Lymphoma*
4. Abscess

• There is soft tissue density in the perigastric region involving the omentum that I most consistent with lymphoma. While perigastric hematoma can have a similar appearance, the patient does not have risk factors for bleeding such as anticoagulation. Gastric cancer arises from the mucosa of the stomach and would not present as a predominantly perigastric mass. The attenuation and imaging features are not characteristic of abscess, which usually measures fluid or complex fluid attenuation and has a rim-enhancing wall.

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

• Seeking out a more thorough clinical history from the electronic medical record or directly from the ordering provider is an approach that can mitigate framing bias, since this bias arises from how a question is asked or how a problem is presented.
• Reviewing the prior radiologist report after reviewing prior imaging and rendering an interpretation is an approach to mitigate alliterative error.
• Referencing sources of information beyond one’s personal experience, including relevant peer-reviewed publications, is an approach to mitigate availability bias.
• Being mindful of known combinations of injuries is an approach to mitigate satisfaction of search.
