[Subarachnoid Hemorrhage Associated with Bevacizumab during Chemotherapy for Clinical Stage Ⅳ Sigmoid Colon Cancer-A Case Report].

The case is a 59‒year‒old woman. A detailed examination of fecal occult blood revealed a diagnosis of cStage Ⅳ sigmoid colon cancer cT3N1M1b(liver H2, hilar liver and celiac artery lymph nodes). After excision of the primary lesion, decided to give chemotherapy.

Realistic Virtual Endoscopy of the ventricle system and haptic-based surgical simulator of hydrocefalus treatment.

New methods and software tools for automatic extraction of the ventricle system from magnetic resonance imagery (MRI) data, ventricle part classification, and realistic texturing are proposed to support Virtual Endoscopy (VE). Volume- and surface-based medical atlases are intensively used as templates in the methods. The processed ventricle-related surfaces are then utilized in a haptic-based system, which provides a surgeon with several basic functions simulating "virtual treatment" of hydrocephalus.

[High uptake of N-isopropyl-p-[123I]-iodoamphetamine (123I-IMP) demonstrated by dynamic SPECT in some cases of glioma].

Selective high uptake of N-isopropyl-p-[123I]-iodoamphetamine (123I-IMP) in the brain tumors is not common, the mechanism of uptake in the brain tumor is not yet clearly understood. Among 26 cases of gliomas investigated by dynamic SPECT, 4 cases including 2 cases of anaplastic astrocytoma and 2 cases of oligodendroglioma, showed high uptake of 123I-IMP. New three detector type camera which enables us to investigate rapid successive scanning, was used in our study.

[Changes of regional perfusion in metastatic brain tumor and peritumoral area after radiosurgery: a study by 123I-IMP dynamic SPECT].

Changes of regional perfusion in the tumor, peritumoral edematous area and juxtatumor brain after radiosurgical treatment for metastatic brain tumor were investigated by dynamic SPECT using 123I-IMP. The SPECT was performed in 12 patients before and 1, 7 and 30 days after stereotactic irradiation. A region of interest (ROI) was selected each in the tumor, peritumoral edematous area, juxtatumor brain and ipsilateral cerebellum.
