Predicting Breast Attenuation in Patients Undergoing Myocardial Perfusion Scintigraphy: A Digital X-Ray Study. |

|---|---|---|
Attenuation artifacts are the most common sources of error in myocardial single-photon emission computed tomography (SPECT)
imaging. Breast artifacts are the most frequent causes of false positive planar images in female subjects. The purpose of
this study was to predict breast adverse attenuation by measuring breast tissue thickness with digital x-ray. Sixty-five consecutive female patients with angina pectoris,
who were referred to myocardial perfusion scintigraphy were enrolled in this study. Eighteen patients with normal perfusion
imaging and normal coronary angiography composed the first group, whereas the second group consisted of 28 patients with a
positive exercise electrocardiogram with anterior ischemia on myocardial perfusion imaging and greater than 50% left anterior
descending artery stenosis on angiography. Nineteen patients in the third group had normal exercise electrocardiograms and
normal coronary angiographies, but anterior ischemia on perfusion imaging. Digital x-ray records were obtained for measuring
breast tissue thickness and Hounsfield density. The rate of breast adverse attenuation was 40% (19/47) in patients with anterior ischemia. The sensitivity and specificity of the prediction of breast
adverse attenuation (lateral density less than 550 Hounsfield) were 79% and 11%, respectively. When breast attenuation for
a breast thickness greater than 6 cm measured in the left anterior oblique view was predicted, the sensitivity and specificity
were 79% and 93%, respectively. In conclusion, breast thickness greater than 6 cm measured from the left anterior oblique
view with digital x-ray can predict breast adverse attenuation in female patients, and thereby may decrease the number of
unnecessary invasive diagnostic procedures to be performed.
