Objective: To summarize multi-detector row CT (MDCT) and magnetic resonance imaging (MRI) features of retinal detachment and evaluate the diagnostic value of these two imaging modalities.
Methods: The MDCT and MRI manifestations were reviewed in 45 cases (47 eyes) of retinal detachment, among which 16 cases (17 eyes) were examined by MDCT and 29 cases (30 eyes) by MRI. Thirty-two cases (33 eyes) were confirmed by operation, and the other 13 cases (14 eyes) were confirmed based on the clinical findings.
Results: MDCT and MRI displayed signs of fluid retention between the detached retina and the posterior wall of the eyeball in the cases. Among all these cases, 21 eyes showed simple retinal detachment and 26 had also other pathologies (hemorrhage in 20 eyes and calcification in 6 eyes). Choroidal osteoma was identified in 3 eyes and melanoma of choroid in 5 eyes.
Conclusion: MDCT is sensitive in detecting calcification in the eyes and MRI with a minimal risk of radiation, and shows advantages in displaying hemorrhage and confined retinal detachment. Both MDCT and MR have high clinical value in the diagnosis of retinal detachment, and their choice depends on the individual condition of the patients.
