Abby, Ami, and Debbie talk about watching The Exorcist. The scariest thing in the film was brain imaging before CT scan, which...holy shit guys! Apparently this movie was made just one year before CT scans came along. Neurologists really did perform direct carotid puncture to inject dyes into the circulation to image the brain back then, and they really did something called pneumoencephalography. They injected air into the CSF via spinal, which would rise (as air tends to do) and make the brain more visible via X-ray. As a person who performs modern spinals, Abby comments that this would produce the mother of all headaches and possibly brain damage. A truly horrifying film.
