Pamela Found Our Rotation Particularly Exciting; Very Highly Commended Mainly ‘Cus She Arouses”:

Patient details

Film details

Objects (e.g. lines, electrodes)

Rotation

Penetration

Expansion

Vessels

Hila

Costophrenic angles

Mediastinum

Cardiothoracic Ratio

Soft tissues and bones

Air (diaphragm, pneumothorax, subcut. emphysema)

Chest X-ray interpretation[edit]

Preliminary is ABCDEF:

AP or PA

Body position

Confirm name

Date

Exposure

Films for comparison

Analysis is ABCDEF:

Airways (hilar adenopathy or enlargement)

Breast shadows/ Bones (rib fractures, lytic bone lesions)

Cardiac silhoutte (cardiac enlargement)/ Costophrenic angles (pleural effusions)

Diaphragm (evidence of free air)/ Digestive tract

Edges (apices for fibrosis, pneumothorax, pleural thickening or plaques)/ Extrathoracic tissues

Fields (evidence of alveolar filling)/ Failure (alveolar air space disease with prominent vascularity with or without pleural effusions)

Chest X-ray: cavitating lesions differential[edit]

Neck sagittal x-ray: examination checklist[edit]

ABCD:

Osteoarthritis: x-ray signs[edit]

LOSS:

Loss of joint space

Osteopyhtes

Subcondral sclerosis
