Term 1 of 53
lateral projection: medial aspect of hand is in contact with IR while the coronal plane of hand is
perpendicular to IR.
thumb is positioned as for PA projection and is supported on a radiolucent sponge; wrist will be
slightly pronated; fingers may be separated to prevent superimposition
advantage: superimposition of second through fifth metacarpals. Superimposition of second
through fifth phalanges individually demonstrated.
which projection of the fingers is shown?
which projection of the thumb is shown?
which projection of the hand is shown?
what structures can be seen/ what is the advantage of using this projection?

,Definition 2 of 53
what is the source-image receptor distance (SID) for a routine exam of the hand?
8 x 10 inches (18 x 24 cm) lengthwise
8 x 10 inches (18 x 24 cm) or 10 x 12 inches (24 x 30 cm) lengthwise
40 inches minimum
8 x 10 inches (18 x 24 cm) or 10 x 12 inches (24 x 30 cm)
Definition 3 of 53
which projection of the wrist is shown?
PA oblique: anteromedial surface of wrist is in contact with the IR so that coronal plane of
wrist forms a 45 degree angle with IR.
position may be supported by wedge sponge, stair-step sponge, or patient's thumb
PA: anterior surface of the wrist is in contact with IR. Fingers are flexed to form a loose fist,
placing wrist in firmer contact with the IR and opening inter carpal joints.
lateral: beginning with hand positioned for PA oblique thumb, patient flexes MCP joints 2
through 5 with the fingers extended, "tenting" hand until thumb is in lateral position
PA oblique: palmar surface of hand is in contact with IR as for PA projection of hand.
Coronal plane of thumb will be 45 degrees to the plane of IR.
,Definition 4 of 53
how should the patient be positioned for a routine exam of the wrist?
standing upright with arms raised
kneeling with hands on the floor
seated at the end of the table with elbow flexed 90 degrees and forearm resting on the
table
lying down with legs extended
Definition 5 of 53
which projection of the thumb is shown?
lateral: medial surface of wrist is in contact with IR. Coronal plane of wrist is perpendicular
to IR.
lateral: beginning with hand positioned for PA oblique thumb, patient flexes MCP joints 2
through 5 with the fingers extended, "tenting" hand until thumb is in lateral position
PA: anterior surface of the wrist is in contact with IR. Fingers are flexed to form a loose fist,
placing wrist in firmer contact with the IR and opening inter carpal joints.
lateral: medial or lateral surface of the hand may be in contact with the IR, depending on
which brings finger of interest near to IR. Other fingers are flexed or extended as necessary
to leave affected finger free of superimposition.
note: affected finger is supported parallel to IR
, Definition 6 of 53
how should the central ray be positioned for a routine exam of the hand / PA and PA oblique
projections?
perpendicular to the second MCP joint
seated at the end of the table with elbow flexed 90 degrees, with forearm rotated internally
to exaggerated degree of pronation
perpendicular to the third MCP joint
perpendicular to the midcarpal area
