    The study analyzed MRI features of cervical lymph nodes in 32 patients with differentiated thyroid carcinoma undergoing ¹³¹I therapy.

    Cervical ultrasonography detected lymph node metastasis in only 15.6% of cases, highlighting its limitations in evaluation.

  • 3

    MRI revealed that 65.5% of radioiodine-avid lymph nodes were round to ovoid, while 32.8% were irregular in shape.

  • 4

    Ill-defined margins were present in 69.0% of nodes, and 91.4% lacked a lymphatic hilum, indicating potential malignancy.

  • 5

    The study emphasizes the need for comprehensive imaging assessments due to overlapping characteristics of radioiodine-avid and negative nodes.
