About dental imaging

  • Permitted modalities
    • Plain films
    • Panoramic tomography
    • Skull films
    • Intraoral films
    • Cone Beam CT
  • Not allowed
    • MRI
    • ultrasound
    • IV contrast administration
    • everything not on list above
I have no experience with any non-dental modality

Techniques that have helped me improve

Custom reslicing is better

  • Don't just rely on orthogonal views
  • Examine panoramic reslice for every dental case
  • Continually reslice along structures of interest
  • The more uniformity you can visually create between successive cases, the more nuanced your diagnosis can become.

Learn from normal

Employ a systematic technique

  • Peruse every volume in a systematic way
  • Prevents misses from focusing too quickly on obvious pathology
  • Refine technique based on feedback from misses/errors over time

Don't rely on stats in textbooks

  • The problem with relying on heuristics like "found 75% of the time in anterior mandible in middle-aged females" is that it constrains your concept of where a lesion can show up in the jaws.
  • It's a good place to start when you have no idea about something, but the more you see, the more you realize that the textbooks have colored your diagnostic lens

Serial overlays are the best for identifying subtle recurrences

  • Don't rely on side-by-side visual matching. Overlay the scans and get the exact answer
  • example cases: 170810 & 150782

Interesting cases

  • This is our list of cases that we flag as having eductational value at Canaray

Dental powerpoints

  • Images mostly courtesy of Drs. Susanne Perschbacher and Fatima Jadu at the University of toronto Faculty of Dentistry.
  • This is typical fare when dentists talk about odontogenic lesions
  • Generally focused on dental imaging, not medical imaging.

Dental anomalies

Cysts of the jaws

Bone dysplasias

Bone patterns in the jaws

Benign tumors of the jaws

Malignant tumors of the jaws
