¹¹¹In-DTPA cisternography with SPECT/CT for the evaluation of normal pressure hydrocephalus.

Although new MR imaging techniques can provide high-resolution information on CSF dynamics and are not associated with ionizing radiation, SPECT/CT cisternography is a valuable alternative for those with contraindications to MR imaging. SPECT/CT cisternography combines functional and anatomic imaging to provide accurate and detailed information on CSF distribution to be used in conjunction with clinical findings for the diagnosis and evaluation of NPH, as illustrated in this case report.
