Sinus occlusion after SRS for transverse-sigmoid sinus dural arteriovenous fistulas TO THE EDITOR: We were interested to read the study by Umekawa et al. 1 evaluating outcomes of 34 patients with transverse-sigmoid sinus dural arteriovenous fistulas (TSS DAVFs) after stereotactic radiosurgery (SRS) (Umekawa M, Shinya Y, Hasegawa H, et al. Safety ev...
Conference Paper
Purpose: The aim of this study was to evaluate the frequencies of cancer in asymptomatic subjects undergoing whole-body magnetic resonance imaging (WB-MRI) within the Oncologically Relevant Findings Reporting and Data System (ONCO-RADS) categories. Methods or Backround: We retrospectively included 2064 asymptomatic subjects participating in the WB-...

Background Whole-body magnetic resonance imaging (WB-MRI) has emerged as a valuable tool for cancer detection. This study evaluated the prevalence rates of cancer in asymptomatic individuals undergoing WB-MRI according to the Oncologically Relevant Findings Reporting and Data System (ONCO-RADS) classifications in order to assess the reliability of...

Objective To investigate the association between the magnetic resonance imaging (MRI) signal characteristics of skull base chordoma and radiosurgical outcomes.Methods Twenty-four patients with skull base chordomas treated with Gamma Knife radiosurgery (GKRS) after previous surgical resection were retrospectively (2001–2021) examined. Pre-GKRS MRIs...
Article
Objective To explore the impact of outflow patency on radiosurgical outcomes of lateral sinus dural arteriovenous fistulas (DAVFs). Methods We retrospectively examined 83 lateral sinus DAVFs treated with Gamma Knife radiosurgery (GKRS) between 1995 and 2020. Two neuroradiologists blinded to the therapeutic outcomes served as imaging evaluators on...
Conference Paper
Purpose: Sinovenous outflow plays a role in clinical presentation, classification, and therapeutic strategy of transverse-sigmoid sinus dural arteriovenous fistulas (TSDAVFs). Therefore, we conducted the study to explore the impact of sinovenous outflow patency on radiosurgical outcomes of TSDAVFs. Methods or Background: We retrospectively (1995–20...

Purpose: To investigate sinovenous outflow restriction (SOR) in lateral sinus dural arteriovenous fistulas (LSDAVFs) after Gamma Knife radiosurgery (GKRS) and its association with complete obliteration. Methods: We retrospectively (1995-2019) enrolled 39 patients with LSDAVFs who had undergone GKRS alone and evaluated their angiography and magne...
Article
Purpose: MRI and MR angiography (MRA) are noninvasive methods for examining cavernous sinus dural arteriovenous fistulas (CSDAVFs) after radiosurgery. In this study, we investigated the accuracy of unenhanced MRI/3-dimensional time-of-flight (3D TOF) MRA in evaluating CSDAVF obliteration as compared with digital subtraction angiography (DSA). Meth...
Article
OBJECTIVE Gamma Knife surgery (GKS) obliterates 65%–87% of cavernous sinus dural arteriovenous fistulas (CSDAVFs). However, the hemodynamic effect on GKS outcomes is relatively unknown. The authors thus used the classification scheme developed by Suh et al. to explore this effect. METHODS The authors retrospectively (1993–2016) included 123 patien...
