Anterior Oblique Positions Rao And Lao : Chest

The correct answer is left because in a right anterior oblique (RAO) view, the area of interest and the best image provided is for the left lung.

The heart needs a left anterior oblique (LAO) view with a rotation of 60 degrees. This particular view allows for a better visualization of the left ventricle and the coronary arteries. By angling the X-ray beam towards the left side of the patient's body and rotating the image, the heart can be seen from a more optimal perspective, aiding in the diagnosis and evaluation of any potential cardiac abnormalities or blockages in the coronary arteries.

This statement is true because the position mentioned in the question requires the use of a grid. The use of the word "requires" indicates that the grid is necessary for the position, suggesting that it is an essential tool or skill for the job.

The CR should be directed at T7 level.

The kV range refers to the kilovolt range, which is a unit of electrical potential difference. In this case, the correct answer is 110-125, indicating that the kilovolt range falls between 110 and 125.

The statement is true because taking exposure on the 2nd inspiration ensures that the X-ray image captures the lungs at their maximum inflation. This is important for accurate diagnosis and assessment of lung conditions. By waiting for the 2nd inspiration, the radiographer can ensure that the lungs are fully expanded, allowing for better visualization of any abnormalities or pathologies.

The CR (carriage return) is placed at T7.

Collimation refers to the process of limiting the size of the x-ray beam to the area of interest, reducing unnecessary radiation exposure to other parts of the body. In this case, the correct answer is "lungs" because collimation is commonly used in chest x-rays to focus the x-ray beam on the lungs and surrounding structures. By collimating the beam to the lungs, radiation exposure to other areas, such as the pubis, illiac crest, or ASLS, can be minimized.

Colimation refers to the process of aligning or focusing a beam of radiation into a narrow, well-defined path. In the context of the question, it is implied that colimation occurs in the lungs. This could be attributed to the fact that the lungs play a crucial role in the respiratory system, where air is drawn in and out through a complex network of bronchial tubes. The narrowing and focusing of the airways within the lungs can be seen as a form of colimation, allowing for efficient airflow and gas exchange.

The correct answer is 180cm. This is because the question asks for the measurement of the SID, and out of the given options, 180cm is the only one that represents a measurement. The other options represent inches and feet, which are not relevant in this context.

The correct answer is 14x17 because it is the largest size listed, indicating that it is the standard size for this position.

The correct answer is left because in the IN RAO (Right Anterior Oblique) position, the arm that should be raised with the palm placed on the head is the left arm. This position is commonly used in medical imaging, particularly in cardiac imaging, to obtain specific views of the heart. By raising the left arm and placing the palm on the head, it helps to move the structures of the chest away from the heart, allowing for clearer visualization of the cardiac anatomy.

In this position, both lungs should be visible, not just one. Therefore, the statement is false.

The patient is positioned with their left anterior shoulder against the image receptor (IR) and rotated 45 degrees. This position is called Left Anterior Oblique (LAO).

The recommended mAs is 4.0.

The IR is positioned 1 inch from the vertebra prominens. This means that when taking an X-ray or other imaging scan, the image receptor (IR) should be placed 1 inch away from the vertebra prominens. The vertebra prominens is the most prominent bony landmark on the back of the neck, specifically the spinous process of the seventh cervical vertebra. Placing the IR at this specific distance ensures accurate and consistent imaging results.
