In the last 20 years, there have been advances in imaging techniques for pituitary diseases. Magnetic resonance imaging (MRI) particularly presents high-quality structural images and the essential information needed to authorize surgery, radiation therapy, and/or drug therapy. These images can assist in monitoring long-term outcomes. Recent technological advances, such as the advent of 7-Tesla MRI, have been used for measuring tumor consistency in pituitary adenomas. Microadenomas and other pituitary incidentaloma have been more recognized in the presence of golden-angle radial sparse parallel imaging and conventional dynamic contrast-enhanced techniques. However, standard structural (anatomical) imaging, mainly in the form of MRI, acts inadequately to identify all tumors, especially microadenomas (< 1 cm diameter), recurrent adenomas, and several incidentalomas. In this respect, nuclear isotope (radionuclide) imaging promotes tumor detection beneficially. All these imaging improvements may play a central role in clinical practice, especially when considering diagnosis, differential diagnosis, or definitive intervention. They further form accurate diagnosis, advise surgery, and decrease the risk of disrupting normal pituitary function.

Neuroendoscopic techniques have been used to treat hydrocephalus for more than 100 years. With the personalized design of surgical approaches, increased knowledge of ventricular anatomy, and improved neuroendoscopic equipment, the last 20 years have witnessed tremendous advances in the development of neuroendoscopic technology, especially in the treatment of hydrocephalus. Except for obstructive hydrocephalus, the application of neuroendoscopic technology in the field of hydrocephalus is also expanding and has received good results, mainly in the fields of pediatric hydrocephalus and communicating hydrocephalus. Additionally, many scholars have achieved satisfactory results in the application of ventriculoscopy to complex hydrocephalus. Among neuroendoscopic techniques, the third ventricular floor fistula and cyst wall fistula methods are commonly used in the treatment of hydrocephalus and are highlighted in this chapter. Undoubtedly, neuroendoscopic technology has become one of the key treatment methods for hydrocephalus, with its high success rate, few complications, and accurate long-term efficacy.
