BACKGROUND AND PURPOSE: Conventional CT has generally lower detectability of bone
marrow invasion than MR imaging due to lower tissue contrast. The purpose of this study …

Purpose: To evaluate the value of skull-base abnormality on MRI for predicting local
recurrence in nasopharyngeal carcinoma. Materials and Methods: Between November 1988 …

Early detection of skull base invasion in nasopharyngeal carcinoma (NPC) is crucial for
correct staging, assessing treatment response and contouring the tumor target in …

Purpose Plain radiographs, computed tomography (CT), and more recently magnetic
resonance imaging (MRI) are used routinely to stage carcinoma of the nasopharynx. Tc-99m …

Background Skull base invasion in nasopharyngeal carcinoma (NPC) was shown to be a
poor negative prognostic factor, and dual-energy CT (DECT) has heralded a new approach …

Background. Our aim was to assess the capacity of CT versus MRI for delineating to the
primary tumor extent of nasopharyngeal carcinoma (NPC) in treated patients. Methods. From …

CT scans of the nasopharynx and the base of skull were performed in 54 patients with
histologically proven NPC. The CT findings are compared to those obtained by routine …

Dear Editor in Chief, We recently read the article by Dr. Yang Zhan et al., titled “Dual-energy
CT for the detection of skull base invasion in nasopharyngeal carcinoma: comparison of …

Twenty‐nine patients with nasopharyngeal carcinoma (NPC) with skull base or intracranial
involvement were analyzed by high‐resolution computed tomography (CT). We divided the …

Methods Sixty-one cases pathologically proven as nasopharyngeal carcinoma were
selected from August 1993 to September 2001. three-dimensional reconstruction with spiral …
