List of important Radiology Mnemonics

Radiology mnemonics for easy memorization of forgetful stuff. They are specially helpful for USMLE and other licensing exams. This is ever growing dynamic list of mnemonics, please add yours comments to them.

Chest radiograph: checklist to examine Mnemonic

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 Mnemonic

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 Mnemonic

“If you see holes on chest X-ray, they are weird”:

Wegener’s granulomatosis (now known as granulomatosis with polyangiitis)

Embolic (pulmonary, septic)

Infection (anaerobes, pneumocystis, TB)

Rheumatoid (necrobiotic nodules)

Developmental cysts (sequestration)

Histiocytosis

Oncological

Lymphangioleiomyomatosis

Environmental, occupational

Sarcoid

Alternatively: L=Left atrial myxoma

Elbow ossification centers, in sequence Mnemonic

CRITOE:

Capitellum

Radial head

Internal epicondyle

Trochlea

Olecranon

External epicondyle

Head CT scan: evaluation checklist Mnemonic

Blood can be very bad”:

Blood

Cistern

Brain

Ventricles

Bone

Neck sagittal x-ray: examination checklist Mnemonic

ABCD:

Anterior: look for swelling

Bones: examine each bone for fractures

Cartilage: look for slipped discs

Dark spots: ensure not abnormally big, or could mean excess blood

Osteoarthritis: x-ray signs Mnemonic

LOSS:

Loss of joint space

Osteopyhtes

Subcondral sclerosis

Subchondral cysts

T2 vs. T1 MRI scan Mnemonic

"WW 2" (World War II):

Water is white in a T2 scan.

Conversely, a T1 scan shows fat as being whiter.

Upper lobe shadowing: causes Mnemonic

BREASTS:

Beryllium

Radiation

Extrinsic allergic alveolitis

Ankylosing spondylitis

Sarcoidosis

TB

Siliconiosis
