SHAFT Generalised osteoporosis- ground glass

appearance Cortex thinning- pencil point thinness

METAPHYSIS White line of FRANKEL-

– Zone of well calcified cartilage in provisional zone of calcification

Corner sign- TRUMMERFELD ZONE-

– fragmentation above the calcified cartilage

Pelke’s sign-epiphyseal spur Epiphyseal #

EPIPHYSIS Signet ring sign

CENTRAL RAEFACTION WIMBERGER’S LINE

– Sharply outlined epiphysis-thick cortex

METAPHYSIS

Tetrology of fallot

Tetrology of fallot

BOOT SHAPED HEART– Concavity is due to pulmonary oligemia due to

pulmonary artery underdevelopment.– Apex is elevated-

RVH-displaces LV up and out

– Right sided aortic arch-30%

Tetrology of fallot

Diaphragmatic hernia

Gross mediastinal shift Diaphragm not seen Bubbly shadow in the lung area Continuity in the bowel gas shadows from

abdomen to chest

Duodenal atresia

Doubble bubble apparance Absence of

gas shadow distal

to it

Jejunal obstruction

Intestinal obstruction

Multiple air fluid level No gas shadow beyond obstructuon

Thymus shadow

Location- anterior mediastinum Overlies precordium, aortic arch, trachea

Chest x ray-difficult to discriminate from cardiac shadow.

Thymic wave sign- scalloped or wave contour of the organ due to impression of the anterior reflection of the ribs

SAIL SIGN- triangular, slightly convex right lobe with sharply demarkated base caused by the minor fissure.
