Position + Projections

Posteroanterior (PA) Projection

projection of CR from posterior (back) to anterior (front)

Anteroposterior (AP) Projection

projection of CR from anterior (front) to posterior (back)

AP Oblique Projection

projection of upper/lower limb that is rotated

not a true AP projection, needs a qualifying term to indicate which way it is rotated such as medial or lateral rotation

in picture it is a APO projection - medial rotation (from AP)

PA Oblique Projection

projection of upper/lower limb with lateral rotation (from PA)

must also need qualifying term to indicated which way it’s rotated

CR enters posterior surface + exits anterior surface

Mediolateral Projection

lateral projection described by path of CR

the medial/lateral sides are determined w patient in anatomic position

CR enters the medial aspect + exits lateral aspect

Lateromedial Projection

lateral projection is described by path of CR

medial/lateral sides are determined w patient in anatomic position

CR enters the lateral aspect + exits the medial aspect

Supine Position

lying on back, facing upward

Prone Position

lying on abdomen, facing downward

Erect Position

upright position, stand/sit erect

specifically erect R lateral position

Recumbent Position

lying down in any position (prone, supine, on side)

dorsal recumbent = lying on back (supine)

ventral recumbent = lying face down (prone)

lateral recumbent = lying on side (R/L lateral)

specifically recumbent L lateral position

Trendelenburg Position

recumbent position w body titled head LOWER than feet

Reverse Trendelenburg Position

recumbent position w body tilted w head HIGHER than feet

Left Lateral Recumbent Position (for enma tip insertion)

recumbent oblique position w patient lying on left anterior side, right knee + thigh flexed + left arm extended down behind the back

Lithotomy Position

recumbent (supine) w knees + hips flexed and thighs abducted + rotated externally, supported by ankle supports

position seen frequently in surgical suite for certain urinary studies

Lateral Position

side view described by side of body closest to IR or body part from which CR exits

erect R lateral

Oblique Position

refers to angled position in which nether the sagittal or coronal body plane is perpendicular or at a right angle to IR

LPO Position

left posterior aspect of body is closest to IR

CR exits from left?

RPO Position

right posterior aspect of body closest to IR

RAO Position

oblique position which right anterior aspect closer to IR, can be erect or recumbent general body positions

specifically a recumbent RAO position

LAO Position

oblique position which left anterior aspect closer to IR, can be erect/recumbent general body positions

Decubitus Position

Right/Left Lateral Decubitus Position - AP/PA Projection

Dorsal Decubitus Position - L/R Lateral

Ventral Decubitus Position - R/L Lateral

Axial Projection

Superoinferior and Inferosuperior Axial Projection

Tangential Projection

AP Axial Projection - Lordotic Position

Transthoracic Lateral Projection (R Lateral Position)

Dorsoplantar and Plantodorsal Projection

Parietoacanthial and Acanthioparietal Projection

Submentovertical (SMV) and (Verticosubment) VSM Projection
