Exam 19: Pediatric Computed Tomography

Computed tomography is not useful in diagnosing congenital abnormalities such as scoliosis, lesions of the vertebral bodies, and osteomyelitis.

Imaging of the head and spine in children depends on all of the following expect:

Computed tomography can be used to evaluate deformities in the musculoskeletal system including: I. congenital hip dysplasia II. femoral anteversion III. leg-length discrepancy

The dose of contrast material for children is:

Advantages of multidetector computed tomography include all of the following except:

It is not necessary to keep resuscitative supplies in the computed tomography room.

Computed tomography remains the primary screening modality for the abdomen and pelvis in pediatric patients.

Modification of dose parameters is the most straightforward and important method to reduce dose.

For chest computed tomography, shallow breathing in the child is adequate.

Toys, books, and puzzles are a welcome diversion for the child.

All of the following are infections where computed tomography is used in children except:

Radiation exposure control can be achieved by: I. careful review of all orders II. coverage limited to the area of interest III. selection of appropriate scanning parameters

The technologist should follow the following basic tenets when performing a pediatric examination: I. should be able to use immobilization II. should be honest with the patient and the patient's family III. should be knowledgeable and well prepared

When positioning the patient for computed tomography of the brain and face, it is not important to have the head centered in the gantry.

Any syndrome or condition with a respiratory risk should be recorded and brought to the attention of the radiologist before sedation is given.

For older infants and toddlers, oral or rectal chloral hydrate is the most commonly used drug.

To minimize the risk of infection to the neonatal patient, technologists should do all of the following except:

Successful computed tomographic angiography in children requires optimization of scan technique and contrast administration.

Characterization of fractures and congenital abnormalities of the skeletal system are not well visualized by computed tomography.

The parents are usually an important ally of the technologist and should be included whenever possible.
