RT Journal Article SR Electronic T1 Appearance of Meningioma on 99mTc-HMPAO SPECT: Correlation with MRI JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol.

Balon YR 2016 UL http://tech.snmjournals.org/content/44/2/90.abstract AB On brain perfusion SPECT, a primary brain lesion presents as a localized defect that corresponds to the mass lesion. 99mTc-HMPAO images generally show a focal defect in the region of abnormality, whether containing necrotic tissue, recurrent tumor, or both. Further characterization with MR imaging is needed to confirm the diagnosis, as demonstrated in this case report.
