Endocrine radionuclide scintigraphy with fusion single photon emission computed tomography/computed tomography

Area of Science:

• Nuclear medicine
• Radiology
• Endocrinology

Background:

• Hybrid imaging systems combine functional and anatomical data.
• Single Photon Emission Computed Tomography/Computed Tomography (SPECT/CT) offers advanced diagnostic capabilities.
• Endocrine disorders require precise imaging for effective management.

Purpose of the Study:

• To review the diagnostic benefits of SPECT/CT in various endocrine disorders.
• To synthesize the utility of hybrid imaging in endocrine gland function assessment.
• To highlight improvements in scintigraphy through SPECT/CT integration.

Main Methods:

• Literature search of MEDLINE and PubMed (2003-2015).
• Keywords included "SPECT/CT", "parathyroid adenoma", "thyroid cancer", "neuroendocrine tumor", "pheochromocytoma".
• Analysis of retrieved manuscripts for descriptive synthesis of SPECT/CT applications.

Main Results:

• SPECT/CT enables simultaneous acquisition and fusion of functional and anatomical datasets.
• Improved diagnostic capability for endocrine disorders through combined imaging.
• Demonstrated benefits for parathyroid, thyroid, neuroendocrine, adrenal, and pheochromocytoma/paraganglioma imaging.

Conclusions:

• SPECT/CT leverages the synergy between radiopharmaceutical imaging and CT anatomy.
• This integration leads to enhanced diagnostic accuracy.
• SPECT/CT has a meaningful impact on patient care for endocrine conditions.
