Which technique is best when imaging the transthoracic projection for humeral head?
Respiration: Breathing technique is preferred if patient can cooperate. Patient should be asked to gently breathe short, shallow breaths without moving affected arm or shoulder. (This will allow best visualization of humerus by blurring out ribs and lung structures)
What is transthoracic lateral projection?
The modified transthoracic supine lateral scapula is a modification of the supine lateral shoulder, used to safely image patients on spinal precautions, or patients who are unable to move; often employed in major trauma hospitals, it produces a diagnostic lateral projection of the shoulder with no elongation of …
What is the NEER method?
The tangential supraspinatus outlet projection, also called the Neer method, is used to demonstrate possible shoulder impingement in the coracoacromial arch in the shoulder’s supraspinatus outlet area. This projection also might demonstrate dislocations and fractures of the scapula and proximal humerus.

What is a tangential projection?
tangent projection. A projection whose surface touches the globe’s without piercing it. A tangent planar projection touches the globe at one point, while tangent conic and cylindrical projections touch the globe along a line.

How is the proximal humerus examined in transthoracic?
X-ray examination of proximal humerus (shoulder) in lateral view transthoracic. This view is also know as the Lawrence Method, to demonstrate the proximal humerus. A breathing technique is done to blur the overlying ribs and lung markings. Performing this technique and prevented of patient motion the humerus should appear sharp.
What is the exposure time for transthoracic lateral projection?
An AP with neutral rotation is required in addition to the transthoracic lateral projection. Minimum of 2 seconds exposure time with breathing technique (between 2 and 4 seconds is desirable)
How to treat transthoracic lateral projection of the shoulder?
Place affected arm at patient’s side in neutral rotation; drop shoulder if possible. Raise opposite arm and place hand over top of head; elevated shoulder as much as possible to prevent superimposition of affected shoulder.
How big does a transthoracic lateral view need to be?
LAWRENCE METHOD – Transthoracic Lateral View 1 IR size – 24 x 30 cm (10 x 12 inches), lengthwise 2 Moving or stationary grid, vertical, CR to centerline 3 75 +- 5 kV range 4 Minimum of 3 seconds exposure time with breathing technique (4 -5 seconds is desirable)
