In a standard PA chest projection, how should the patient be positioned relative to the image receptor?
Anterior chest against the image receptor
Left side against the image receptor
Posterior chest against the image receptor
Supine on the table
In a PA chest projection, the patient stands facing the image receptor placing the anterior chest directly against it. This positioning reduces magnification of the heart and provides a clearer view of thoracic structures.
For a PA hand radiograph, what is the correct hand placement on the image receptor?
Dorsal side of the hand against the IR
Palm flat on the IR with digits spread slightly
Palm flat on the IR with digits together
Fist resting on the IR with thumb extended
A PA hand projection requires the palm to be flat against the image receptor with the digits slightly separated to prevent overlap. This ensures clear visualization of the phalanges and metacarpals.
Before beginning any imaging procedure, what is the first essential patient care protocol?
Check the patient's blood pressure
Verify patient identity using two identifiers
Perform a pregnancy test
Explain the procedure to the patient
The first essential protocol is to verify patient identity using two identifiers, such as name and date of birth, to ensure the correct patient is imaged. This practice reduces the risk of wrong-patient errors.
Which protective device should be used to minimize gonadal radiation exposure during pelvic imaging?
Lead apron around the neck
Lead-lined gloves
Thyroid shield
Lead gonadal shield
A lead gonadal shield is placed over the patient's reproductive organs to reduce radiation exposure without obscuring the anatomy of interest. This is standard practice whenever it does not interfere with diagnostic information.
What is the recommended source-to-image distance (SID) for a standard chest radiograph to minimize magnification?
48 inches
72 inches
100 inches
40 inches
A 72-inch SID is standard for chest radiographs to reduce magnification of the heart and improve image sharpness. Shorter distances result in greater magnification and potential loss of detail.
Which anatomical landmark corresponds to the level of the T7 vertebra on a PA chest radiograph?
Inferior angle of the scapula
Jugular notch
Vertebra prominens
Xiphoid process
The inferior angle of the scapula aligns approximately with the level of the T7 vertebra. This landmark helps ensure accurate vertical centering of the chest radiograph.
If a patient cannot stand for a chest radiograph, which projection is most appropriate?
PA erect
Lordotic
AP supine
Lateral decubitus
When the patient cannot stand, an AP supine projection is used, often in portable imaging. This allows chest imaging in a non-erect position but may increase cardiac magnification.
On an AP abdomen (KUB) radiograph, the central ray should be directed at which landmark?
Xiphoid process
Anterior superior iliac spine
Iliac crest
Pubic symphysis
The central ray for a KUB is directed to the level of the iliac crests to include the entire abdomen from the diaphragm to the pelvis. Proper centering ensures visualization of critical structures.
A radiograph of the pelvis shows the femoral necks foreshortened; which positioning error most likely caused this?
Feet internally rotated
Feet externally rotated
Knees flexed
Toes pointed inward
Externally rotating the feet causes the femoral necks to move away from the plane of the image receptor, resulting in foreshortening. Proper internal rotation aligns the femoral necks parallel to the IR.
Which patient instruction is most effective for reducing motion artifact during a chest radiograph?
Take shallow breaths
Inhale deeply and hold breath
Exhale and hold breath
Breathe normally
Instructing the patient to inhale deeply and hold the breath stabilizes the thoracic structures and minimizes motion blur. Consistent breath-hold instructions are critical for image clarity.
What is the main purpose of collimation during radiographic imaging?
Prevent patient movement
Adjust the kVp automatically
Restrict the x-ray beam to the area of interest
Increase the source-to-image distance
Collimation confines the x-ray beam to the anatomy of interest, reducing patient dose and scatter radiation. This improves image contrast and quality.
An AP lumbar spine radiograph shows asymmetric pedicles and spinous processes; what error likely occurred?
Incorrect SID
Patient rotation
Insufficient kVp
Excessive collimation
Asymmetric pedicles and spinous processes indicate the patient was rotated instead of being in a true AP position. Proper alignment requires the midsagittal plane perpendicular to the IR.
Which practice best minimizes fetal radiation dose when imaging a pregnant patient?
Repeat images if the first is unclear
Use high kVp and low mAs without shielding
Use lead gonadal shielding
Increase mA to shorten exposure time
Applying lead gonadal shielding protects the fetus by absorbing scatter radiation. It is essential whenever it does not obscure diagnostic anatomy.
During fluoroscopic procedures, which technique most effectively reduces patient radiation exposure?
Increase continuous fluoroscopy time
Use pulsed fluoroscopy and last image hold
Lower kVp for greater contrast
Avoid using lead shielding
Pulsed fluoroscopy and last image hold reduce fluoroscopy time and cumulative dose by capturing images intermittently. This approach limits unnecessary radiation exposure.
Which communication strategy most improves patient comfort during imaging procedures?
Use technical jargon for clarity
Rush through the instructions
Remain silent throughout the exam
Clearly explain each step before proceeding
Clearly explaining each step helps the patient understand what to expect, reducing anxiety and improving cooperation. Good communication is key to patient-centered care.
In an AP axial (Towne) skull projection, the dorsum sellae is projected above the foramen magnum. What positioning error most likely caused this?
Excessive caudal tube angle
Insufficient caudal tube angle
Incorrect source-to-image distance
Head tilted laterally
If the dorsum sellae is projected above the foramen magnum, the central ray was not angled sufficiently caudally. Proper angulation is required to project the dorsum sellae into the foramen magnum.
A lateral lumbar spine radiograph demonstrates closed intervertebral disc spaces. Which factor most likely caused this?
No caudal angulation of the central ray
Patient rotated
Image receptor misaligned
Excessive kVp
Lateral lumbar spine projections require a slight caudal angle (usually 5° - 8°) to open the intervertebral disc spaces. Omitting this angle can cause the spaces to appear closed.
How should technical exposure factors be adjusted for an obese patient to maintain image quality?
Increase SID
Increase mAs with little change in kVp
Decrease mAs
Decrease kVp
Increasing mAs compensates for greater tissue thickness by providing more radiation to the IR, maintaining adequate image density. Excessive changes in kVp can alter image contrast undesirably.
In a 45° RPO projection of the cervical spine, which intervertebral foramina are best visualized?
Left intervertebral foramina
Posterior intervertebral foramina
Anterior intervertebral foramina
Right intervertebral foramina
An RPO (right posterior oblique) position opens the right intervertebral foramina by rotating the spine toward the IR. This projection is used to visualize the foramina on the side closest to the IR.
A PA chest radiograph shows that the apices are clipped. What correction should be made on the repeat exposure?
Increase the mAs
Lower the kVp
Raise the image receptor or center higher
Decrease the SID
Clipping of the apices indicates the top of the image receptor was too low. Raising the IR or centering higher ensures the entire lung apices are included on the radiograph.
