The fractional anisotropy (FA) value calculated by diffusion tensor MRI can indicate the degree of directionality of water diffusion in astrocytic tumors. Here, we report a case of anaplastic astrocytoma in which FA proved invaluable for the preopera

A cor triatriatum is a congenital malformation of the heart which, in almost all cases, is diagnosed in childhood, whereas adult cases are very rare. The hemodynamics of the cor triatriatum is similar to that of mitral stenosis, which sometimes, but

We report a case of granulomatous change of the pituitary stalk caused by Rathke's cleft cyst. A 50-year-old woman complained of thirst and polyuria in December 2000. In January 2001, the patient was suspected to have diabetes inspidus, and MR Imagin

In vivo, water diffusion displays directionality due to presence of complex microstructural barriers in tissue. The extent of directionality of water diffusion can be expressed as a fractional anisotropy (FA) value, using diffusion tensor MR imaging

Hypoxic cells play a key role in the radioresistance of malignant glioma. Interferon-beta, ACNU as nimustine hydrochloride and radiotherapy (IAR) is a common therapy for malignant glioma in Japan. Since hyperbaric oxygenation (HBO) increases oxygen p

BACKGROUND Magnetic resonance imaging (MRI) can provide a preoperative diagnosis of gliomatosis cerebri, but the findings sometimes do not correspond with the clinical symptoms or histologic findings. CASE DESCRIPTION Three-dimensional anisotropy con

Measurement of oxygen pressure (pO2) in tumor tissue is important, because pO2 is a major factor for radiosensitivity in malignant glioma treatment. We attempted to elucidate the changes in pO2 level in glioblastoma tissue of patients under various c

A 45-year-old female presented a peripheral nerve sheath tumor (MPNST), which had progressed to malignancy from a neurofibroma arising in the left cervical vagus nerve. Neuroimaging showed that a tumor grew in the left neck area of the patient, invol

A reduction in cortical benzodiazepine receptor binding potential on late images of I-123 iomazenil SPECT indicates irreversible neural damage or loss. We present the case of a 26-year-old woman with status epilepticus in whom SPECT imaging using I-1
