A patient presents to urgent care clinic and thoracic spine radiographs were obtained. The provided indication was "trauma." The interpretation was "no acute fracture." The patient presented again several days later to the emergency department, at which time a nearly identical set of thoracic spine radiographs were obtained. The provided indication at this time was "pain, history of breast cancer, evaluate for metastasis." The interpretation was "absence of left T11 pedicle, most likely representing osteolytic metastasis", which was confirmed on subsequent CT.

A 40-year-old woman presented to another hospital with headache. A brain MRI was interpreted as a probable glioma of the left temporal lobe. The patient sought a second opinion at your hospital. A radiology trainee reviews the outside report and images and renders a preliminary interpretation that agrees with probable glioma. The supervising radiologist reviews the images and revises the final interpretation to a benign dilated perivascular space, which is the correct diagnosis. What perceptual or cognitive bias most likely affected the radiology trainee's report?
