Cone-beam CT (CBCT) systems specifically designed for hard-tissue imaging of the maxillofacial region have recently become commercially available. The newly-developed CBCT system, CB Throne (Hitachi Medical Corp., Tokyo), is characterized by a number of features such as low dose, sub-millimeter spatial resolution, and a small footprint. This system has been(More)
The purpose of this study was to investigate the accuracy of distance measurements of implant length based on periapical radiographs compared with that of other modalities. We carried out an experimental trial to compare precision in distance measurement. Dental implant fixtures were buried in the canine and first molar regions. These were then subjected to(More)
This report presented a 4-year-old girl who had atonic partial seizure of the right leg accompanied by impaired equilibrium. This patient had a generalized tonic-clonic seizures before, and had been on anticonvulsant medication. Mild cataplexy of the right leg and flail trunk while standing occurred abruptly. Based on clinical symptoms, physiological(More)
We report here a case of a patient with subacute sclerosing panencephalitis (SSPE) and we have analyzed periodic events using dipole tracing methods to clarify the origin of periodic synchronous discharges and myoclonus. Both source generators were located in the subcortical part of the cerebrum, an area adjacent to the thalamus. Although the(More)
We describe here chronological single photon emission computed tomography (SPECT) with N-isopropyl-p-[123I]iodoamphetamine (123I-IMP) of a patient with subacute sclerosing panencephalitis (SSPE) from the early clinical stages. The case, an 8-year-old Japanese girl, was in clinical stage I of the disease on admission. A SPECT study with(More)
