[Abstract] Objective: To evaluate the relationship between pituitary macroadenomas and cranial nerves in the cavernous sinuses by contrast-enhanced three-dimensional fast imaging employing steady-state acquisition with phase cycling (CE 3D-FIESTA-C).Materials and Methods: Forty patients with pituitary macroadenomas were prospectively collected, all of whom scanned the CE 3D-FIESTA-C and contrast-enhanced brain volume (CE BRAVO) sequence, and the display rate of cranial nerves in bilateral cavernous sinus was calculated for each patient.Results: On CE 3D-FIESTA-C sequence, the display rate of cranial nerves in the cavernous sinuses was 75.0%, 25.0%, 71.3%, 71.3%, 41.3%, respectively, which was higher than CE BRAVO sequence (P<0.01). On the CE 3D-FIESTA-C sequence, the cranial nerves at the tumor site was interrupted or not shown due to the influence of the tumor to determine the invasion of the ipsilateral cavernous sinus, and the sensitivity and specificity of diagnosis were 41.7% and 95.8%, respectively.Conclusions: The CE 3D-FIESTA-C sequence can better display the cranial nerves in the cavernous sinuses in patients with pituitary adenoma. By observing whether the cranial nerve in the cavernous sinuses is interrupted or not displayed due to the influence of tumor, it can assist the diagnosis of whether the ipsilateral cavernous sinus is invaded. |
