What are the four positions for X-rays?
Body positions
- erect: either standing or sitting.
- decubitus: lying down.
- supine: lying on back.
- Trendelenburg position: the patient is supine (on an inclined radiographic table) with the head lower than the feet.
- prone: lying face-down.
- lateral decubitus: lying on one side. right lateral: right side touches the cassette.
Where do you center an L spine X-ray?
The CR is directed vertically to the center of the abdomen at the level of the iliac crests. The radiograph in this projection demonstrates the vertebral bodies and the intervertebral disk spaces.
How do you take an X-ray of the lumbar spine?
The x-ray machine will be placed over the lower part of your spine. You will be asked to hold your breath as the picture is taken so that the image will not be blurry. In most cases, 3 to 5 pictures are taken.
What is Lao position?
In E, the patient is in a left anterior oblique (LAO) position, and in F, the patient is in a right anterior oblique (RAO) position, both corresponding to PA oblique projections.
What is a Rao position?
Patient positioning for a single-contrast esophagram Place the patient in the right anterior oblique (RAO) position to offset the esophagus from the spine. The patient’s right arm is placed alongside the body, with the left knee flexed.
Where is L1 and L2 located in your back?
lumbar
The L1 vertebra is located in the spinal column of the lumbar (lower back) region inferior to the T12 vertebra and superior to the L2 vertebra. Like the other lumbar vertebrae, L1 has a large, roughly cylindrical region of bone known as the body, or centrum, which makes up most of its mass.
How do you position the lateral lumbar spine?
Lumbar Spine Lateral Position of patient Lying on the left or right side (lateral recumbent) with the knees and hips flexed for comfort. The elbows are flexed and the arms are at a right angle to the body. The knees are superimposed. The midcoronal plane is aligned to the midline of the grid.
What is Rao and Lao?
Rotation describes the position of the image intensifier around the longitudinal axis of the patient. LAO refers to rotating the camera to the patient’s left (catheter and spine will be on the right side of the image), RAO to the patient’s right (catheter and spine on the left side of the image).
What does Lao mean in radiography?
Abbreviation for left anterior oblique projection, used in chest radiography, especially to assess the size of the left atrium and ventricle.
Where is T1 and T2 located on the spine?
thoracic vertebrae
The thoracic vertebrae T1 is located in the upper part of the back. It’s the first section of the thoracic vertebrae, so it is located between the seventh cervical vertebra (C7) and T2.
What are Z joints?
The facet joints (or zygapophysial joints, zygapophyseal, apophyseal, or Z-joints) are a set of synovial, plane joints between the articular processes of two adjacent vertebrae. There are two facet joints in each spinal motion segment and each facet joint is innervated by the recurrent meningeal nerves.
What position is Rao?
right anterior oblique
The right anterior oblique (RAO) position is usually used in preference to the left anterior oblique (LAO) position. An RAO position of 35°-40° gives a wider space for an image of the esophagus between the vertebrae and the heart.
What is LPO in radiology?
Abbreviation for left posterior oblique, a radiographic projection.
What is chest Bucky?
A bucky is typically used for table or wall mounted x-ray systems and holds the x-ray cassette and grid. A bucky, is a device found underneath the exam table, a drawer like device that the cassette and grid is slid into before shooting x-ray.
