Figure 4-2. You will have to assist with such special procedures, as a body section
radiography, which produces visual slic es of the human body by means
of computerized axial tomography.
i. Assisting with Prenatal Procedures. Whenever radiography is considered
for use as part of prenatal care, the benefits of the exam must outweigh the inherent
risks associated with exposure for the fetus. Although ultrasonography has replaced
radiography, there may be occasions on which a prenatal radiograph or fetogram may
be required. Prenatal radiographic procedures may be necessary if the mother has
broken her back in a car wreck, or if something is suspected to be wrong with the fetus.
A fetogram may be needed to determine if a mother's pelvis is wide enough to allow
passage of an irregularly positioned infant, for example, a breach baby. However, prenatal
radiography is not justified, for example, to determine if a baby's head is bigger than the
vaginal opening. (Legal action is not likely to ensue just because the physician opts for
a Caesarean section.)
j. Assisting with Urogenital Procedures. Included in this category are the
intravenous pyelogram and the hysterosalpingogram (HSG). The IVP is used to check
functioning ability. An HSG of the uterus and fallopian tubes may help to reveal why a
woman is having difficulty getting pregnant.
