WebThe definitive diagnosis of intrapulmonary hamartoma is made by showing fat attenuation (–40 to –120 HU) within the lesion, which is visible in up to 50% of cases. Hamartomas of soft-tissue attenuation with no evidence of intralesional fat are regarded as pulmonary nodules of unknown origin. WebThe attenuation equation is: Ax= A0e-ux The most frequently noted effects of attenuation in myocardial SPECT are artifacts associated with breast attenuation in women and diaphragmatic attenuation in men Attenuation artifacts are more severe using Tl201than with Tc99m due to Thallium’s lower energies ATTENUATION electronic mouse toy for cats
