Single-photon emission computed tomography/computed tomography in brain tumors

Area of Science:

• Neurology
• Radiology
• Nuclear Medicine

Background:

• Anatomic imaging (CT, MRI) is crucial for brain tumor assessment.
• Functional imaging (PET, SPECT) provides malignancy and biopsy guidance.
• Nuclear medicine is vital post-treatment for tumor assessment and monitoring.

Purpose of the Study:

• To highlight the importance of combining functional and anatomic imaging for brain tumor evaluation.
• To discuss the role of SPECT/CT fusion in improving diagnostic accuracy and patient management.

Main Methods:

• Review of SPECT and CT/MRI fusion techniques in brain tumor imaging.
• Discussion of integrated dual-modality SPECT/CT systems.
• Analysis of fused images for lesion localization and exclusion of physiologic uptake.

Main Results:

• Imaging fusion provides precise localization of neoplastic lesions.
• SPECT/CT fusion overcomes SPECT's anatomic detail limitations.
• Integrated SPECT/CT systems facilitate practical, everyday use.

Conclusions:

• Fusion of SPECT and CT/MRI significantly aids brain tumor diagnosis and management.
• Dual-modality SPECT/CT systems offer a practical solution for improved patient care.
• Enhanced localization and monitoring through fused imaging optimize treatment planning.
