Question 15.27. Regarding lung cancer treatment planning, which is TRUE?

A. Adrenal lesion biopsy is no longer needed in the era of MRI and

MDCT.

B. Routine imaging of the brain and bone in the absence of clinical

suspicion of metastases is unwarranted.

C. CT of the chest requires intravenous contrast to exclude adrenal

metastases.

D. Liver should be imaged in its entirety on an initial staging CT because

of the high incidence of liver metastases.

Question 15.28. Regarding lymphoma, which is TRUE?

A. Lymphangiography remains a highly sensitive and specific way to

evaluate portal and mesenteric lymphadenopathy.

B. CT is an effective way to evaluate bone marrow involvement.

C. Routine MRI is equally as sensitive as CT for detection of lym-

phadenopathy in the chest, abdomen, or pelvis.

D. Gallium scintigraphy is better than PET in the detection of lym-

phadenopathy from lymphoma.

E. The added sensitivity of PET is its ability to adequately characterize

bone marrow involvement by lymphoma.

Question 15.29. Regarding breast cancer, which is TRUE?

A. Annual screening mammography should begin at age 50 years.

B. There is no role for early screening in high-risk patients.

C. Calcium is an indication of benign disease.

D. Final assessment on mammography is based on likelihood of malig-

nancy.

E. Percutaneous biopsy of a potential cancer is contraindicated for fear

of seeding the needle tract.

Question 15.30. Regarding nonmammographic breast imaging, which is TRUE?

A. Sonography is not useful for the evaluation of dense breasts.

B. To distinguish cysts from solid masses, sonography should be used as

a first-line tool.

C. Because of breast geometry, sonography cannot be used for needle

biopsy guidance.

D. MRI is limited because of the inability to have MRI-guided biopsies.

Question 15.31. Regarding breast cancer staging, which is NOT true?

A. Lymphoscintigraphy is useful for the staging of large breast cancers

(>5 cm).

B. Disease greater than one quadrant is known as multicentric disease.

C. More than one focus of disease in the same quadrant is known as

multifocal disease.

D. Sonography is limited in the detection of depicting carcinoma in situ.

E. MRI is useful in the detection of infiltrating lobular cancer.
