Background: Call Readiness Simulation

? Computer aided online simulation (SIM) of emergency imaging studies

? Designed to test residents for readiness for call

? Providing proficient & objective assessment of resident competence in the emergency/critical care imaging & affirmation of Milestone achievements

Background: Call Readiness Simulation

? 8 hour simulation of 65 emergent & critical care cases of varying degrees of difficulty, including normal studies

? Presentation via full DICOM image sets ? Dictation of free responses into text boxes labelled

Critical findings Incidental findings Acuity ranking

Background: Call Readiness Simulation

? SIM was taken by 127 first (R1) & second (R2) year residents from 16 USA radiology training programs

? Chiari type 1 malformation was presented

69% of residents failed to recognize the cerebellar tonsillar ectopia Only 6% of the residents made the correct diagnosis and gave the appropriate

recommendation

Conclusion: An observational gap exists in detecting cerebellar tonsillar ectopia which could delay urgent treatment or place

patients at risk for complications of a lumbar puncture

Teaching Points

? Define cerebellar tonsillar ectopia and Chiari I malformation and discuss CT and MRI imaging findings

? Review CT and MRI imaging findings of critical mimics of Chiari I malformation

? Discuss the importance of making the proper recommendations for patients with cerebellar tonsillar ectopia
