Knee (Beclere method intercondylar view)
Updates to Article Attributes
Body
was changed:
The Beclere method intercondylar view is an additional projection of the knee, used to better examine the tibial plateau and femoral intercondylar spaces. It is anecdotally known as a 'notch view'
Patient position
- patient is supine on the table with the knee flexed 40 degrees
- image receptor is placed under the flexed knee slightly more superior than that of the AP projection
Technical factors
- axial projection
-
centring point
- central ray is angled to align perpendicular to the tibia central to 1.5 cm distal of the apex of the patella
-
collimation
- superior to include the distal femur
- inferior to include the proximal tibia/fibula
- lateral to include the skin margin
- medial to include medial skin margin
-
orientation
- portrait
-
detector size
- 24 cm x 30 cm
-
exposure
- 60-70 kVp
- 7-10 mAs
-
SID
- 100 cm
-
grid
- no
Image technical evaluation
- tibial plateau should be free from any superimposition
- femoral condyles should be free from superimposition with the intercondylar fossa in profile, giving the appearance of a 'notch'
Practical points
- ensure before carrying out x-ray the image receptor is superior enough to contain the image
