Deeper inspirations show more lung and result in better overall images with less haziness at the lung bases and less enlargement of the heart and mediastinum. A good inspiration on a PA CXR shows at least 9 posterior ribs. The following films were of the same patient and taken using the same AP projection.

How many posterior ribs should be visible?
Ideally 7-9 ribs should be visible. Less than 7 suggests poor effort by the patient and/or low lung volumes as in restrictive lung disease, atelectasis, etc. 10 or more ribs typically suggests hyperinflation as in COPD, asthma, bronchiectasis.
How many ribs Visualised are considered adequate inspiration?
To check for an adequate degree of inspiration, count the anterior ribs on the right. In a good radiograph, 6 anterior ribs should be visible above the right hemidiaphragm. The radiograph used to demonstrate proper alignment also shows evidence of a good degree of inspiration (see Figure 1).
How many posterior ribs are shown above the diaphragm?
10 posterior ribs in the midclavicular line above the diaphragm.
How many anterior and posterior ribs are there?
Anatomic Landmarks The thoracic cavity is made up of 12 pairs of ribs that connect in the posterior thorax to the vertebral bodies of the spinal column. In the anterior thorax, the first 7 pairs of ribs are attached to the sternum or breastbone by cartilage. The lower 5 ribs do not attach to the sternum.
How many ribs CXR hyperinflation?
more than 6 anterior or 10 posterior ribs above the diaphragm level on the midclavicular line.
What level of the rib is considered a good inspiratory chest PA view?
Radiologists consider a chest X-ray to be of good quality when the trachea is centered and equidistant from the head of the clavicle on both sides, the spine is visible as a transparent structure through the heart shadow, and there is full inspiratory effort ( the right 6th rib is at the midpoint of the hemidiaphragm on
How many ribs does anteriorly have?
Each rib is a curved, flattened bone that contributes to the wall of the thorax. The ribs articulate posteriorly with the T1–T12 thoracic vertebrae, and most attach anteriorly via their costal cartilages to the sternum. There are 12 pairs of ribs.
What is the normal cardiothoracic ratio?
The cardiothoracic ratio is measured on a PA chest x-ray, and is the ratio of maximal horizontal cardiac diameter to maximal horizontal thoracic diameter (inner edge of ribs/edge of pleura). A normal measurement is 0.42-0.50.
How do you count ribs on CXR?
Clavicle / Ribs
- The clavicle and ribs act as landmarks when assessing the adequacy of inspiration taken by the patient.
- The anterior end of approximately 5-7 ribs should be visible above the point at which the mid-clavicular line intersects the diaphragm.
- Less than 5 ribs indicates incomplete inspiration.
How many ribs do we have?
Most people have 24 ribs, with 12 on each side of the body. The ribs and rib cage are excellent examples of the human body’s multi-faceted and multi-functional design. They are strong enough to support the skeleton and protect the vital organs in the chest cavity, including the heart, lungs, and spleen.
What is poor inspiration?
Films taken without a full inspiration are described as having a “ poor inspiratory result ”. This may result from a poor inspiratory effort or any other condition that prevents full inspiration. This patient’s chest x-ray is normal in full inspiration.
Where is the 8th and 9th rib?
These ribs, known as true ribs, also connect to your spine in the back. The 8th, 9th, and 10th rib pairs don’t connect directly to your sternum, but they are connected to each other by cartilage that attaches to the costal cartilage of the 7th rib pair. These ribs also attach to your spine in the back.
