Practical applications of nuclear medicine in imaging breast cancer.

The rise in incidence, morbidity, and mortality of breast cancer has triggered multiple imaging efforts to detect this malignancy early, stage it accurately, and monitor it with precision in the posttherapeutic course. Among different imaging modalities, nuclear medicine provides an important contribution to the clinical management of breast cancer. This article discusses four practical applications based on the use of radionuclides in the evaluation of breast malignancy, focusing on scintimammography, preoperative tumor localization procedure using radioactive seeds, sentinel nodal scintigraphy, and F-18 fluorodeoxyglucose positron emission tomography/computed tomography.

Infection scintigraphy: added value of single-photon emission computed tomography/computed tomography fusion compared with traditional analysis.

Purpose: Positron emission tomography (PET)/computed tomography (CT) imaging is a powerful dual-modality integrating physiology and anatomy. Analogously, fusing separate single-photon emission computed tomography (SPECT) and CT images can overcome interpretive challenges in characterizing and localizing abnormalities. This study explores the value of SPECT/CT image fusion compared with traditional "side-by-side" SPECT-CT image review for infectious /inflammatory processes.

Endocrine neoplasm scintigraphy: added value of fusing SPECT/CT images compared with traditional side-by-side analysis.

Purpose: Positron emission tomography (PET)/computed tomography (CT) imaging integrates physiology and anatomy, providing a powerful dual-modality approach. Analogously, fusing independently acquired single photon emission computed tomography (SPECT) and CT images can overcome interpretive challenges in characterizing and localizing abnormalities by either modality alone, potentially enhancing diagnostic confidence. This study explores the added value of SPECT/CT image fusion compared with traditional "side-by-side" SPECT/CT image review for a variety of endocrine neoplasms.
