they make the news as medical misadventure.

ƒ Orientation of images is essential to avoid critical incidents
ƒ DR is particularly hazardous when it is so easy to alter the patient’s orientation on the detector.
Cervical spine obliques
Cervical spine obliques are a particular minefield

You might say does it really matter? You might say “does it really matter?” “Surely if the patient was to have surgery for foraminal narrowing an MRI would have also been done”
ƒ
However..........
ƒ Patient may have gone to the GP for left arm pain
ƒ The doctor has to decide whether the pain is cardiac or cervical spine in origin. i l i i i i ƒ If the obliques are reversed the foramina on the left side might look fine and the patient has the inconvenience of g
having to see a cardiologist unnecessarily.
For some of us knowing which is left and which is right is easy

including me I have to really think especially when the patient is in an unusual position.

Please, if you have a pen and paper try this simple test.

With each image shown write down left or right and we will find just how easy‐

Looking back at the previous slide you can see that PA Chest g

has been selected ƒ
Therefore the machine expects the patient to be in the PA position.

In the heat of the moment‐

trying to get an image, before b f
the patient sinks forward or sideways, it is easy to forget to change to an AP chest setting.

The image you acquire will be back to front and your only proof of what happened will be your lead marker.

ƒ
I reviewed 259 oblique cervical spine examinations
ƒ
Images were acquired on GE digital or Kodak, Toshiba, Fuji or Agfa CR‐ (I found issues with all modalities)
Results: ƒ 7 examinations that were labelled so badly it was impossible to figure out their laterality.
ƒ 54 had markers added post processing so may have been 54

correct‐ or not!

This gave 20% of patients who MAY OR MAY NOT have correct reports
ƒ
Check list: ƒ Correct patient correct body part ƒ clearly label your image with a lead letter appropriately placed BEFORE
i l l d BEFORE you expose.

Remember: In a court of law post processing p

IF all you take from this is how annoying I was droning on about letters just maybe it will prompt you to be careful and ALWAYS use them!
