| Comment: If an adenoma is suspected or
is a clinical possibility then noncontrast CTs are done in order to get
accurate densitometry values. IV contrast can then be given in cases of
suspected tumor or metastases. On noncontrast CT a Hounsfield measurement
of 18 or less is consistent with an adenoma. |
