  1. Radiology Lines Review Jeff Binder R.T. (R)

  2. 1.) yellow circle 2.)purple line 3.) red line 4. Blue lines

  3. 1.) ADI – Should be 1-5mm for children, 1-3mm for adults 2.)McGregors line – odontoid less than 8mm above this line 3.) Spinolaminar line – should be smooth curve 4.) Pre vertebral space – Top 5mm, middle 7mm, bottom 20mm

  4. 1.) Red angle 2.) yellow measurement

  5. 1.) Boehler’s angle – 28-40*, above or below this range is possible calcaneal fx 2.) Heel pad measurement – Distance between skin and calcaneus. 25<mm = acromegaly

  6. Name the parts of the long bone

  7. 1.) Metaphysis 2.) Physis (growth plate) 3.) Epiphysis 4.) Diaphysis (shaft) 5.) Periosteum 6.) Apophysis (attachment site for ligament or tendon)

  8. Blue line: Iliofemoral line. Should be smooth. Fx or Slipped femoral capital epiphysis will disrupt the line Yellow line: Shenton’s line. Should be smooth curve. Fx/SCE will disrupt Purple angle: Femor Neck angle. 120*-130* is normal range. Above=Coxa Valga Below=Coxa Vara Red measurement: acetabular depth. 7-18mm average. Increased by osteomalacia, Paget’s, or RA. Decreased in congenital hip dysplasia Brown line: Skinner’s line, Fovea capitus must be below the horizontal line. Fx or SCE will elevate the line.

  9. Blue angle: Center edge angle; 20*-40*; increased by osteomalacia, Paget’s, or RA. Decreased by join effusion Orange line: Kline’s line; altered by FX or SCE Red line: Kohler’s line; If femur head crosses the line then it is called Protrusio Acetabuli. Osteomalacia, Paget’s, and RA cause it Orange measurements: Superior (3-6mm), axial (3-7mm), and medial (4-13mm) (teardrop) distances *never average these measurements If medial joint space (teardrop) exceeds 11mm or 2mm between right and left then Waldenstrom’s sign. Common in Legg-Calve-Perthes

  10. Blue lines: Ac joint space. Average superior and Inferior. ~3mm Red Line: Acromiohumeral joint space. 7-11mm Rotator cuff tear decreases Dislocation or joint effusion increases Yellow lines: Glenohumeral joint space. Average all 3. 4-5mm Posterior dislocation increases measurement CPPD or OA decrease measurement

  11. RAO Position Structure, level, side

  12. Right c4/5 IVF The first IVF is C2/3 so count down from there. This is an ROA so the right side of the neck is touching the film therefore RIGHT IVF’s will be visualized.
