Implication

Clinical study demonstrates post-treatment radioiodine scans detect additional metastases in thyroid carcinoma, highlighting the need for therapeutic imaging and regional views.

Key Points

To determine the diagnostic efficacy of post-therapy radioiodine (I-131) scintigraphy compared to pre-treatment diagnostic scans in detecting residual or metastatic thyroid carcinoma.
Evaluated imaging results from 24 patients with well-differentiated thyroid carcinoma across 42 treatment sessions.
Compared immediate post-therapy scans following therapeutic doses of I-131 with low-dose pre-treatment diagnostic scans.
Analyzed the detection sensitivity of regional rectilinear views relative to total-body images.
Post-therapy I-131 scans identified additional malignant lesions in 10 of 24 patients (42%) and on 13 of 42 scan occasions (31%) that went undetected on diagnostic scans.
In 4 patients, metastatic lesions were visualized exclusively on regional rectilinear scan views and remained undetectable on total-body views.
