Quick Guide on Radiographic Positioning

L

• LAQUERRIERE AND PIERQUIN METHOD – Ulnar groove projection.Ref: K.Clarke. Positioning in Radiography. 11th Ed.
• LAUENSTEIN AND HICKEY METHODS – Lateral hip projection demonstrating the acetabulum and upper end of femur.
• LAUENSTEIN – Routine turned lateral hip projection.
• LAUENSTEIN AND HICKEY METHOD – As for turned lateral hip but angle the vertical central, ray 20 degrees cephalad.
• LAURINS VIEW – View of the patella.
• LAW – Demonstrate the petrous temporal region.Head in the lateral position, then rotate the head 15 degrees towards the film. Centre 5cm above and 5cm behind the EAM away from the film with the tube angled 15 degrees towards the feet.
• LAW METHOD (FACIAL BONES) – Projection to demonstrate the floor and posterior wall of the antrum.Patient sitting PA with the head fully extended so that the chin and zygoma of the side of interest, and the nose, are in contact with the cassette. Angle the central ray upward 30 degrees from the horizontal and centre to the lower antrum.Ref: Law, F.M.(1933). Nasal accessory sinuses, Ann. Roentgenol. 15:32-51, 53-76.
• LAWRENCE METHOD – Lateral view of the proximal humerus.Supine, horizontal beam axial shoulder.
• LAWRENCE METHOD – Transthoracic lateral humerus.
• LENTINO METHOD – See carpal bridge view.
• LEONARD-GEORGE METHOD – Demonstrates the femoral head and neck.Patient supine. A curved cassette is placed on the medial aspect of the leg of interest (between the thighs). Direct the central ray perpendicular to the femoral neck.
• LEQUESNE METHOD (FALSE PROFILE VIEW) – View of the acetabulum in profile.Patient standing with their back against the vertical bucky. Move the unaffected hip forward so that the pelvis makes an angle of 60 degrees with the bucky. Central the horizontal central ray the affected hip. See also Urist’s view.
• LETOURNEL VIEW – Iliac wing view.
• LEWIS METHOD – The routine view of the sesamoid bones of the first metatarsal. Ref: K.Clarke. Positioning in Radiography. 11th Ed. LILIENFELD (CALCANEUM)See coalition view.
• LILIENFELD (HIP) – A posterolateral projection of the ileum and acetabulum.Patient prone then raise the unaffected side by 75 degrees. Centre at the level of the greater trochanter of the hip in contact with the film.
• LILIENFELD (SYMPHYSIS PUBIS) – An superoinferior projection of the pubic and ischial bones and symphysis pubis.Position as for AP pelvis then raise the body by 45 degrees. Centre in the midline at the level of the greater trochanter. See also Staunig Method.
• LINDBOLMAP  – lordotic chest. Patient leans back 30+ dgerees, centre to mid sternum.
• LODGE-MOOR PROJECTIONS – Lateral oblique projections to demonstrate the cervical articular facets (four views in total). Patient supine with the X-ray tube on the right hand side. First projection with the patients right side elevated by 20 degrees. Second projection with patients left side elevated by 20 degrees. For both views, centre the horizontal central ray to C5. When the raised side is nearest to the tube then angle 5 degrees cephalad. When the raised side is away from the tube then angle 5 degrees caudal. Repeat the two projections from the left side.
• LORENTZ METHOD (MODIFICATION) – See Danellus-Miller method.
• LOW-BEER METHOD – Parietotemporal projection.Position the head in the lateral position. Angle the horizontal central ray upward 10 degrees and anteriorly 33 degrees. Centre to the back of the head so that the beam enters at the level of the lower orbital margin and passes through the foraman magnum. Similar appearances to Stenvers view.
• LOWENSTEIN’S VIEW – Routine frog lateral hips.
• LYSHOLM METHOD – Profile view of the petrosa, EAM, and the mastoid cells. Head in the lateral position then rotate 15 degrees towards the affected side. Angle the central ray 30 degrees from the vertical and centre through the foramen magnum.
