Image Protocol for the Sonographic Study of the Thyroid Gland n 420
Criteria
Begin studies with a survey of the thyroid gland and associated structures in at least
2 scanning planes.
• As a general rule, the parathyroid glands are not appreciated sonographically
unless they are abnormal.
• Do not share study results with the patient. Legally, only physicians can give a
diagnosis.

Criteria
• In most cases, for women under 30 and lactating and pregnant women, breast
sonography has become the first phase of imaging for evaluating palpable
masses. Breast sonography, however, is not recognized as a screening study for
microcalcifications.
• Breast sonography is generally performed to determine the composition or charac-
terization of a localized lesion or lesions (that may or may not be palpable) and to
further evaluate mammographic and clinical findings.
• Additional indications for breast sonography include guidance for biopsies, treat-
ment plan for radiation therapy, and evaluating complications associated with
breast implants.
• In some cases, whole breast scanning may be recommended for diffuse diseases
such as fibrocystic disease.
• Begin studies with a survey of the structure(s) in at least two scanning planes.
• Do not share study results with the patient. Legally, only physicians can give
diagnoses.
• Use the following image of normal breast tissue as a technical guideline. Remem-
ber that the thickness of the sonographically distinct layers of the breast varies
with age.
