[Liver Metastasis in a Gastric Cancer Patient--A Case of Successful Radiofrequency Ablation Combined with Degradable Starch Microspheres Transcatheter Arterial Chemoembolization].

A 60-year-old male patient underwent curative surgical resection for gastric cancer. After the surgery, the patient was diagnosed with T4b, N3b, ly3, v2, CY0, fStageⅢc gastric cancer, and adjuvant systemic chemotherapy using S-1 and CDDP was administered. However, follow-up computed tomography (CT) scan examination taken 2 months after surgery revealed a pancreatic fistula and retroperitoneal abscess, and percutaneous drainage was performed.

Superselective coaxial microballoon-occluded coil embolization for vascular disorders: a preliminary report.

Purpose: To evaluate the safety and effectiveness of superselective coil embolization with coaxial microballoon occlusion (B-coiling) for vascular disorders.

Materials And Methods: Clinical data were retrospectively evaluated for 16 consecutive patients (6 men, 10 women; mean age, 70 y; age range, 57-80 y) with vascular disorders who underwent B-coiling with 0.010-0.

MRI and CT findings of the giant cell tumors of the skull; five cases and a review of the literature.

Purpose: To investigate CT and MR findings of giant cell tumors (GCTs) of the skull, an unusual site for such tumors.

Materials And Methods: CT and MR features of five histologically proven giant cell tumors of the skull were retrospectively reviewed. We also reviewed 22 cases in the literature that included MR or CT findings.

Origin of high signal intensity in the cavernous sinus in MR angiographic source images: correlation between MR and conventional angiography.

Objective: To investigate the origin of a high signal intensity in a cavernous sinus on magnetic resonance (MR) angiography.

Methods: Time-of-flight MR angiography was performed in 20 patients scheduled for conventional angiography for disease not related to carotid cavernous fistula. Venous drainage pattern was assessed, and flow rate to a cavernous sinus was semiquantitatively evaluated on conventional angiography.

Effect of stage 1 sleep on auditory cortex during pure tone stimulation: evaluation by functional magnetic resonance imaging with simultaneous EEG monitoring.

Background And Purpose: Responses of the auditory cortex to sound during sleep have been explored with somewhat discrepant results. The purpose of this study was to investigate the effect of stage 1 sleep on signal intensity changes in the auditory cortex in response to pure tone stimulus measured by functional MR imaging.

Methods: Six sleep-deprived subjects were exposed to a series of echo-planar images for 30-40 minutes.
