Episode notes
Importance of Neurologic Exam
- Neurologic exams and clinical history are critical for accurate diagnosis and to guide imaging interpretation.
- Imaging narrows the differential diagnosis but doesn't replace thorough clinical evaluation.
Systematic CT Head Review
- Develop a personal systematic approach to read CT heads, checking the brain, bleeds, strokes, arteries, cisterns, and bone fractures.
- Use different window settings on CT to optimize detection of various abnormalities like subdural hemorrhages and fractures.
Contrast Use Cautions on CT
- Avoid CT contrast in patients with renal failure or history of contrast allergies; pre-treatment protocols can require extensive planning.
- Consult radiology to consider non-contrast studies or alternate modalities if contrast risks outweigh benefits.
