Flashcards in Thoracic Spine Deck (16):

What is part of the minimal diagnostic series of the thoracic spine?

AP and Lateral.


What are the additional views of the thoracic spine?

Swimmer's lateral and Oblique.


What thoracic vertebra are visible in an AP thoracic view?

(Should be taken with close collimation.)


What are the 2 pitfalls of the AP Thoracic?

Upper thoracics are surrounded by lucent lung fields (high contrast body area).
Lower thoracics are surrounded by dense abdomen (low contrast body area).


Describe the pedicles in an AP Thoracic view:

Oriented lengthwise in the sagittal plane (seen on end, appear as circles).
Useful in identifying rotation.


What things make it easier to visualize the articular processes in an AP Thoracic?

Rotation, lateral flexion, and scoliosis.
(In normal situations, they're difficult to see b/c they are thin, overlapping structures.)


T/F: The ends of SP's in the T-spine frequently curve to L or R; this has no clinical significance.



How do you determine anterior vs posterior ribs in an AP Thoracic view?

Posterior extends from the spine; medial to lateral slope is superior to inferior.
Anterior extends to nonvisualized costal cartilage; lateral to medial slope is superior to inferior.


In what direction do the TP's extend in the thoracic spine?



What joint spaces are not consistently seen or evaluated on the AP thoracic radiograph?

Intervertebral, zygapophyseal/facet, costovertebral, and costotransverse joint spaces.


What are the pitfalls of the lateral thoracic view?

Upper thoracics is surrounded by arms, shoulders, and scapula.
Mid thoracics surrounded by lungs.
Lower thoracics surrounded by dense abdomen.


What structures are best visualized on a lateral thoracic view?

IVD's, pedicles (in profile), IVF, venous channels of hahn, zygapophyseal/facet joints (b/c they're in the coronal plane), and sternoclavicular joints.


What is used to check thoracic kyphosis?

George's/posterior body margin line.


What structures are best visualized on a swimmer's cervical/thoracic?

Cervicothoracic junction.


How many views of the ribs do you need to take on a swimmer's Cx/Tx view?

2 perpendicular views (90 degrees to each other).
(Place the site of pain/trauma closest to the film.)


When taking an x-ray of the sternum what 3 views should be taken (swimmer's)?

Lateral and PA (it places the sternum closest to the film).
RAO projects the sternum away from the heart shadow.
