Study Notes
Anatomical Terminology
- Anatomical terminology is a scientific way to describe parts of the human body precisely and consistently.
- Anterior aspect: The front view of a patient.
- Posterior (dorsal) aspect: The back view of a patient.
- Lateral aspect: A side view of a patient. The side of the head is a lateral aspect of the cranium.
- Medial aspect: The side of a body part closest to the middle line, for example, the inner side of a limb.
Planes of the Body
- Three planes are used for describing body position in medical imaging:
- Median sagittal plane: Divides the body into equal right and left halves. A sagittal plane is parallel to this but divides the body into unequal parts.
- Coronal plane: Divides the body into anterior and posterior parts.
- Transverse or axial plane: Divides the body into superior and inferior parts.
Positioning Terminology
- Erect position: The patient is standing or sitting. The patient can be positioned with the anterior, posterior, or lateral aspect of their body against a cassette.
-
Decubitus position: The patient is lying down.
- Supine: Lying on their back.
- Prone: Lying face down.
- Lateral decubitus: Lying on their side (right or left).
- Semi-recumbent: Reclining, in a position between supine and sitting, with trunk posterior aspect against a cassette.
- Upper-limb projections: Patients are often seated at the table during imaging, so the legs are not positioned under the table to avoid exposure of the gonads.
Limb Positioning Terminology
- Rotation: Movement around an axis. Examples include medial (internal) and lateral (external) rotation.
- Flexion: Decreasing the angle of a joint.
- Extension: Increasing the angle of a joint.
- Abduction: Movement away from the midline.
- Adduction: Movement toward the midline.
Projection Terminology
-
Projection: Defined by the direction of the central ray relative to the body.
-
Antero-posterior (AP): Central ray enters the anterior aspect, travels parallel to the middle, and exits the posterior aspect.
-
Postero-anterior (PA): Central ray enters the posterior aspect, travels parallel to the middle, and exits the anterior aspect.
-
Lateral: Central ray passes from one side of the body to the other, along the coronal and transverse plane. (Right Lateral or Left Lateral based on the ray entry point.)
-
Oblique: Central ray passes along a transverse plane at an angle to the sagittal plane and emerges on the anterior or posterior aspect. (Anterior Oblique or Posterior Oblique). Specific descriptions depend on the direction.
