APICOLORDOTIC VIEW
LINDBLOM METHOD
 

apicolordotic
AP Lordotic (upright)
AP Lordotic chest x ray is primarily to rule out calcifications and masses beneath the clavicles or in the apices of lungs. Which also some early pathology are evident. Usually AP lordotic is taken with a PA or an AP normal chest x ray. It is also known as the Lindblom Method

Technical Factors and Shielding:



  • IR size - 35 x 43 cm (14 x 17 inches), lengthwise or crosswise.
  • Moving or stationary grid
  • 110 to 125 kV range
  • Secure lead shield around waist to shield gonadsPatient 

Position and Part Position | AP Lordotic: 

apicolordotic
AP Lordotic Radiograph
Patient standing about 1foot (30cm) away from IR and learning
back with shoulders, neck and back of head against IR.
Both hands are on hips, the palms facing out and roll the shoulder towards the tube
Center midsagittal plane to CR and to centering of IR.
Center cassette to CR. (top of IR should be about 3 inches [7 to 8cm] above shoulders on average patient.)
Central Ray, Collimation and Patient Respiration:
CR perpendicular to IR, centered to midsternum (3 to 4 inches [9cm] below jugular notch)
SID of 72 inches (180cm)
Collimate to area of lungs of interest.
Respiration on this projection is same as in normal chest x ray. The exposure is made at the end of sencond inspiration.

AP LORDOTIC SUPINE | ALTERNATIVE | EXCEPTION | TRAUMA


  • If patient is weak and unstable and/or is not able to do the chest x ray erect lordotic position, A supine AP semiaxial can be taken. The shoulder are rolled forward and arms are same as for erect AP lordotic. Angulate central ray 15° to 20° cephalad towards the head and directed to midsternum area.
