and 6 chest leads.
Visualization of bone marrow uptake on a 99mTc-sulfer colloid liver/spleen image is
most likely the result of: A)improper colloid particle size B)insufficient tracer circulation
time C)liver dysfunction D)overactive bone marrow -CORRECT ANSWER C)liver
dysfunction. Bone marrow uptake is visualized on liver/spleen images when severe liver
dysfunction, such as advanced cirrhosis, is present.
During hepatobiliary imaging, which structure will NOT be visualized if cystic duct
obstruction is present: A)common hepatic duct B)common bile duct C)gallbladder
D)small intestine -CORRECT ANSWER C)gallbladder. If cystic duct obstruction is
present, the tracer will be unable to enter the gallbladder. The cystic duct is the passage
between the common bile duct and the gallbladder.

thoracic/lumbar spine is to ascertain: A)the site of tracer administration B)the flow rate
of the cerebral spinal fluid C)that the tracer was not infiltrated -CORRECT ANSWER
C)that the tracer was not infiltrated. The injection site should be imaged first to confirm
that the tracer has not infiltrated outside the subarachnoid space. Reinjections may be
required if infiltration is confirmed.
On Wednesday a patient had a 125I thyroid study performed; a 125I plasma volume is
ordered to be performed on Thursday. Should a baseline plasma sample be collected
before performing the plasma volume? True or False -CORRECT ANSWER True. A
blood sample collected before the 125I-albumin is injected can provide the background
present in the patient's plasma. This will permit counts from the plasma sample
containing 125I to be corrected for any residual 123I.
89Sr-chloride is used to treat which of the following conditions: A)bone pain
B)polycythemia vera C)rheumatoid arthritis D)malignant effusions -CORRECT
ANSWER A)bone pain. 89Sr-chloride is used to relieve bone pain resulting from

During an imaging procedure a patient indicates a seizure is impending. The most
appropriate action is: A)tell the patient to breathe deep to increase oxygen levels B)stop
the procedure, have the patient lie on the floor with a pillow supporting the head -
CORRECT ANSWER B)stop the procedure. Seizure patients may experience a warning
that a seizure is about to occur. The tech should assist the patient to the floor and away
from objects that may injure the patient. A pillow will cushion the head from the floor.
After administration of 111In-pentetreotide, which areas of the body should be imaged:
A)anterior and posterior chest B)anterior and posterior abdomen C)anterior and
posterior whole body -CORRECT ANSWER C)anterior and posterior whole body.
Because the purpose of 111In-penetreotide imaging is to visualize the unknown primary
site of the cancer or to demonstrate the extent of the disease, anterior and posterior
whole-body images should be performed.
