chest xray Flashcards
changes in mucosal lining is an indication of
inflammation
example of mucosal thickening
thumbprinting,lead pipe colon(ulcerative colitis, toxic magacolon
Discribe toxic megacolon on x-ray
Very dilated colon with evidence of bowel wall oedema with thumb printing and pseudopolyps
lead pipe colon
Featureless segment of colon with loss of normal austral markings
Atelectesis
Condition evidenced with volume loss crowding of pulmonary vessels and tracheal deviation towards the area of atelectasis. Medistanial shift to the atetectesis an hilarious displacement
Pleural effusion
Condition where there is excessive collection of fluid in pleural cavity
Pneumothorax
Hemothorax
Blood in the pleural cavity secondary to rib fractures
Function of mitral valve
Makes sure blood flows from left atrium to left ventricle
What is the radiographic appearance of pneumothorax
Name 4 anomalies of tetralogy of fallout
Right ventricular hypertrophy, high ventricular septal defect,
Abnormal pattern of tetralogy of fallout
Ventricular septal defect, right ventricular outflow tract obstruction, overriding aorta and late right ventricular hypertrophy, boot shaped heart with upturned cardiac apex
Name mimics of pneumothorax
Skinfold artifact- Broad opacity laterally outlined by a Lucent line, Present lung markings crossing the linear shadow, no lung collapse and mediastinal shift
Good penetration
Thoracic spine visible behind the heart
No rotation
Spinous processes half way between medial ends of clavicles
Pleural effusion
Opacification of the lung, Pushed mediastinum to the unaffected lung. `meniscus sign
Pericardial effusion
1)Upper zone vascular prominence
2)Airspace shadowing
3) Septal lines
4) Pleural effusion
Heart is enlarged and has grounded appearance
Left ventricular aneurysm
Common in previous myocardial infarction
Pericardial calcification
Follows contour of the heart
Posterior shoulder dislocation
Widened glenohumeral joint
Humeral head takes on a more rounded light but
Atrial septal defect
Increased pulmonary blood flow
Hill-Sachs lesion
Indentation of humeral head following shoulder dislocation. Humeral head is impacted on the anterior rim of the glenoid
Features of pneumothorax
Visible visceral pleural edge seen as very thin sharp white line
No lung markings
Lung may completely collapse
Peripheral space is radiolucent compared to adjacent lung
Rickets (deficient mineralization of growth plate in pediatrics) radiographic features
Fraying, splaying and cupping
