Pediatric Imaging Flashcards
Indications for pediatric imaging
Congenital anomalies/syndrome
Infectious process
Tumors
Trauma
Principle of Radiation
ALARA as low as reasonably achievable radiation dose
Most frequently performed radiological study in children
Chest x Ray
Check for mediastinal and lung base lesions and localization of lesions seen in frontal view
Lateral view
Most common cause of asymmetry in translucency of the two lungs
Rotation
Ski folds between baby and cassette may mimic
Pneumothorax
Resulting from interdigitation of thymic tissue in the intercostal spaces
Sail sign/ wavy margins
Most common cause of widening of mediastinum
Thymus gland
Presenting a straight course at the right side of the thoracolumbar spine
Umbilical venous catheter
Complex substance composed of phospholipids, protein, and neutral lipids
Surfactant
Other diseases also produce hyaline membrane
Meconium aspiration
Bronchopulmonary Dysplasia
Other name HMD
Respiratory distress syndrome of newborn
Imaging. Diffuse ground glass or finely granular apperance
HMD
True or false. HMD has hyperinflation
False. Hypo inflation
HMD treatment
Positive end-expiratory pressure
Continuous positive airway pressure
Surfactant administered by endotracheal tube
Oxygen and diuretics
Complications arise from treatment HMD
Pulmonary interstitial emphysema
Worsening opacification
Chronic complication
Common cause is administration of oxygen under positive pressure
Bronchopulmonary Dysplasia
Imaging finding. Coarse, irregular, rope like linear densities represent atelectasia or fibrosis
Bronchopulmonary Dysplasia
