What is the Lawrence method?

The Lawrence1 method is used when trauma exists, and the arm cannot be rotated or abducted because of an injury. This projection shows the proximal humerus in a 90-degree projection from the AP projection and shows its relationship to the scapula and clavicle.

What are the indications for taking x-rays for what conditions do you need to take xrays?

Conditions that may call for an X-ray include:

• bone cancer.
• breast tumors.
• enlarged heart.
• blocked blood vessels.
• conditions affecting your lungs.
• digestive problems.
• fractures.
• infections.

What methods of x-ray examination are special?

magnetic resonance imaging (MRI) – the combination of a magnetic field and radio waves to produce three-dimensional pictures. computed tomography scan (CT scan) – the use of x-rays and digital computer technology to create three-dimensional pictures. bone density testing – a procedure to determine bone strength.

Which projections of the shoulder are recommended for a trauma patient with injury to the area?

Recommended Views Radiographs of the injured shoulder in two planes (anteroposterior and axillary lateral or scapular lateral) are absolutely essential to evaluation of an acutely injured shoulder.

Why breathing technique is important in Lawrence transthoracic?

When performing the transthoracic lateral projection (Lawrence method) of the humerus, which breathing technique should be used to improve best image contrast and decrease the exposure necessary to penetrate the body.

What is modified waters view?

The modified Waters method is a good projection to show blowout fractures. This method places the orbital floor perpendicular to the IR and parallel to the central ray, showing inferior displacement of the orbital floor and the commonly associated opacified maxillary sinus.

What is X-ray method?

X-ray methods include a group of spectroscopic techniques of considerable importance. These methods can be used similar to optical methods based on absorption, emission, and diffraction of X-rays. Besides X-ray diffraction and X-ray fluorescence, other X-ray techniques are utilized in practice for analytical purposes.

What are the hazards of x-rays?

While X-rays are linked to a slightly increased risk of cancer, there is an extremely low risk of short-term side effects. Exposure to high radiation levels can have a range of effects, such as vomiting, bleeding, fainting, hair loss, and the loss of skin and hair.

Which of the following projections should be performed using a breathing technique?

An orthostatic (breathing) technique can be performed for the AP projection of the scapula. 53.

What are the proper patient instructions for the 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. Center mid-diphysis of affected humerus and center of IR to CR as projected through thorax.

What is the position of part of the hand for Xray?

Position of part: Place forearm on the table with pronated hand placed over the image receptor. Externally rotate hand 45 degrees and separate digits. Support hand using 45 degree foam wedge if appropriate. Central ray: Perpendicular to the image receptor and directed to the PIP joint of the digit being examined.

What equipment is used to take an xray of a patient?

Patients can be imaged either erect or recumbent. In the erect position, a standard X-ray table and upright Bucky are used. This allows easy and quick positioning and use of a horizontal beam, which is necessary to demonstrate any air-fluid levels in the cranium or sinuses.

What is the radiologic technologist (X-ray Tech) positioning?

This article discusses radiographic positioning to show the fingers and hand for the Radiologic Technologist (X-Ray Tech). Purpose and Structures Shown: This view should demonstrate the bones and soft tissue of the finger. Position of patient: Seated sideways at the end of the the table.

How is a central ray used to examine a finger?

Central ray: Perpendicular to the image receptor and directed to the PIP joint of the digit being examined. Purpose and Structures Shown: This view should demonstrate the bones and soft tissue of the finger. Position of patient: Seated sideways at the end of the the table. Place arm on the table with elbow bent.
