=====3D FIESTA magnetic resonance imaging===== The equivalent Siemens product is called [[CISS]]. 3D-FIESTA magnetic resonance imaging(MRI)for the detection of [[oculomotor nerve palsy]] in a case of [[pituitary apoplexy]] revealed that the left [[oculomotor nerve]] was compressed by the cyst. He underwent transsphenoid tumor resection at 5 days after his hospitalization. Post-operative 3D-FIESTA MRI revealed decrease in compression of the left oculomotor nerve by the cyst. His left oculomotor palsy recovered completely within a few months. Oculomotor nerve palsy can occur due to various diseases, and 3D-FIESTA MRI is useful for detection of oculomotor nerve compression, especially in the field of [[parasellar lesion]]s ((Yamauchi T, Kitai R, Neishi H, Tsunetoshi K, Matsuda K, Arishima H, Kodera T, Arai Y, Takeuchi H, Kikuta K. [Detection of Oculomotor Nerve Compression by 3D-FIESTA MRI in a Patient with Pituitary Apoplexy and Diabetes Mellitus]. No Shinkei Geka. 2014 Feb;42(2):137-42. Japanese. PubMed PMID: 24501187.)).
