Improved diagnosis of "nondelineated" thyroid nodules by oblique scintillation scanning and echography.
The scan of the thyroid gland in oblique projections has enabled us to visualize 11 "cold" thyroid nodules which were not delineated on a traditional anterior view among 825 patients studied in a 2-yr period. Accurate localization of the nodule in the oblique projection facilitated accurate placement of the transducer for echography. The combination of the isotope imaging studies and ultrasound then permitted one to differentiate solid and cystic "cold" nodules. Diagnosis and choice of therapy are therefore enhanced by the addition of oblique views, when needed, and echography.
