Summary
Thallium-201 (201Tl) SPECT imaging effectively visualizes head and neck cancers and lymph node metastases. This diagnostic tool provides valuable information beyond standard imaging methods for cancer evaluation.
Area of Science:
- Nuclear Medicine
- Oncology
- Radiology
Background:
- Thallium-201 (201Tl) is utilized for diagnosing various malignant tumors.
- Its diagnostic utility in head and neck cancer remained unestablished.
Observation:
- This study evaluated 201Tl SPECT imaging in 18 patients with histologically confirmed head and neck cancer.
- 201Tl SPECT images were acquired at 15 minutes and 4 hours post-injection of 148 MBq 201Tl-chloride.
- Semiquantitative 201Tl-indices assessed tracer uptake relative to tumor characteristics.
Findings:
- High 201Tl uptake was observed in all primary tumors and metastatic lymph nodes on both early and delayed images.
- 201Tl-indices did not correlate with tumor size or histological type.
- SPECT imaging demonstrated effective visualization of both primary lesions and nodal involvement.
Implications:
- 201Tl SPECT imaging is effective for visualizing primary head and neck cancer and lymph node metastasis.
- This technique offers supplementary information beyond morphological changes.
- 201Tl SPECT may serve as an adjunctive method in the comprehensive evaluation of head and neck malignancies.
