Missing Word Quiz

Radiography Positions

• The degree of rotation for the right anterior oblique (RAO) projection of the sternum is dependent on the size of the thoracic cavity.
• The left side of the body is turned 45 degrees toward the image receptor, with the CR entering the posterior aspect of the body and exiting the anterior, in the LAO (Left Anterior Oblique) position.
• In the Fowler position, the patient is semi-erect with the head and torso elevated.
• The Modified Sims' position is used to insert a rectal enema tip before a barium enema study.
• The Lithotomy position is used for procedures such as a barium enema study.
• The Trendelenburg position is used to reduce the risk of air embolism.

Radiographic Projections

• A patient is erect with the left side of their chest placed against the image receptor, with the central ray entering the right side of the upper chest and exiting the left, in the Transthoracic lateral position.
• The top of the foot is placed against the image receptor with the perpendicular central ray entering the sole of the foot, in the Axial dorsoplantar projection.
• The Transpedal projection is used to image the foot.
• The Plantodorsal projection is used to image the foot.
• The Tangential plantodorsal projection is used to image the foot.

Radiation Protection

• The cardinal principles of radiation protection are: Shielding, Filtration, Time, and Distance.
• The goal of radiation protection is to minimize the exposure of patients and healthcare workers to ionizing radiation.

Anatomy

• The jugular notch is located on the sternum.
• The suprarenal glands are part of the endocrine system.
• The CT (Computed Tomography) can be used to evaluate both bony and soft tissue anatomy for pathology involving the sternum or the sternoclavicular joints.

Imaging

• The use of 125 kVp is recommended for AP and PA projections of the ribs to reduce skin dose.
• A low SNR (Signal-to-Noise Ratio) is not desirable in digital imaging.
• The lateral abdomen position will best demonstrate the prevertebral region.
• When multiple exposures are placed on a single computed radiography image receptor (IR), lead masking should not be placed on the unexposed regions of the imaging plate.
