Magnetic resonance (MR) imaging detected all ocular tumors, surpassing computed tomography (CT) in identifying lesions and distinguishing associated retinal detachment. MR imaging offers superior specificity for diagnosing intraocular tumors.

Area of Science:

  • Ophthalmology
  • Radiology
  • Oncology

Background:

  • Ocular tumors present diagnostic challenges.
  • Accurate imaging is crucial for diagnosis and treatment planning.
  • Distinguishing between various intraocular neoplasms and associated findings is essential.

Purpose of the Study:

  • To compare the efficacy of magnetic resonance (MR) imaging and computed tomography (CT) in detecting and characterizing ocular tumors.
  • To evaluate the ability of MR imaging and CT to differentiate tumor types and associated findings like retinal detachment.

Main Methods:

  • Retrospective analysis of 67 ocular tumors studied with both MR imaging and CT.
  • Tumor types included primary uveal melanoma, choroidal hemangioma, retinoblastoma, and choroidal metastases.

  • Image analysis focused on lesion detection, differentiation from surrounding tissues, and specific signal characteristics.

    • Main Results:

    • MR imaging demonstrated 100% of lesions, while CT demonstrated 88%.
    • MR imaging better distinguished retinal detachment from neoplasms and visualized extrascleral extension and hemorrhagic necrosis in melanomas.
    • Characteristic MR signal intensities were observed for melanomas (hyperintense T1, hypointense T2), metastases (isointense T1, hypointense T2), and circumscribed choroidal hemangiomas (hyperintense T1, isointense T2).

    Conclusions:

    • MR imaging is superior to CT for detecting intraocular tumors.
    • MR imaging provides enhanced specificity in the diagnosis of various ocular neoplasms.
