XRAY IN NORMAL HIP EXTRA HOW TO

Karen and her husband had already undergone a similar experience with their other German Shepherd, Savannah, successfully treated with total hip replacement surgery by Kimberly Agnello, DVM, MS DACVS, orthopedic surgeon at Penn Vet’s Ryan Hospital. The difference in density between the heart and the air in the lingula enables us to see the silhouette of the left ventricle.When Karen Raspatello realized her dog, Nola, might be suffering from hip dysplasia, she knew what she was in for. The heart is located anteriorly in the chest and it is bordered by the lingula of the left lung. Here an illustration to explain the silhouette sign: This is an important sign, because it enables us to find subtle pathology and to locate it within the chest.

The loss of the normal silhouette of a structure is called t he silhouette sign. These are usely not well seen and we will not discuss them.Īn important mediastinal-lung interface to look for is the azygoesophageal line or recess (arrow). The anterior and posterior junction lines are formed where the upper lobes join anteriorly and posteriorly. Widening of the paratracheal line (> 2-3mm) may be due to lymphadenopathy, pleural thickening, hemorrhage or fluid overload and heart failure.ĭisplacement of the para-aortic line can be due to elongation of the aorta, aneurysm, dissection and rupture. The paraspinal line may be displaced by a paravertebral abscess, hemorrhage due to a fracture or extravertebral extension of a neoplasm. This is called the silhouette sign, which we will discuss later. These lines and silhouettes are useful localizers of disease, because they can be displaced or obscured with loss of the normal silhouette.

Silhouette - for instance the normal silhouette of the aortic knob or left ventricle.

Line or stripe - for instance the right para tracheal stripe.

On the PA chest-film it is important to examine all the areas where the lung borders the diaphragm, the heart and other mediastinal structures.Īt these borders lung-soft tissue interfaces are seen resulting in a:

Pathology of the heart, mediastinum, lungs and pleura, chest wall and abdomen.

Systematic approach to the chest film using an inside-out approach.

The interpretation of a chest film requires the understanding of basic principles. In fact every radiologst should be an expert in chest film reading. The chest x-ray is the most frequently requested radiologic examination.
