Study Notes
Radiation Physics
- Filtration decreases the average energy of the primary beam
- Energy of ionizing electromagnetic radiations is measured in keV (kilo-electronvolts)
Anatomy
- The right colic flexure is formed by the junction of the transverse and ascending colon
- The proximal tibiofibular articulation is best demonstrated in the AP position
- The olecranon process is a proximal structure on the adult ulna
- The normal adult axillary temperature is lower than rectal temperature
Radiography
- Filtration increases the intensity of the primary beam
- A double contrast of the hepatic and splenic flexures is best demonstrated in the right lateral decubitus position
- An x-ray image with many shades of gray from white to black is described as having long-scale contrast
- The period of relaxation of the heart is termed diastole
Patient Care
- An ambulatory patient is one who is able to walk
- A patient lacking decision-making capacity can have their rights exercised by a designated surrogate or proxy
- A radiographer who discloses confidential information to unauthorized individuals may be found liable for breach of confidentiality
Imaging Procedures
- Preparation for an upper GI series typically involves clear fluids 8 hours prior to examination
- The usual position for demonstrating the pulmonary apices below the level of the clavicles in the AP position requires the CR to be directed 15 to 20° cephalad
- The lateral oblique position is not typically used for both single-contrast and double-contrast examinations of the large bowel
Medical Conditions
- Blunting of the costophrenic angles on a PA projection of the chest can be an indication of pleural effusion
- Paralytic ileus demonstrates least x-ray penetrability
