We report three patients with calcium pyrophosphate dihydrate crystal deposition disease within the ligamenta flava of the cervical spine who presented with progressive myelopathy. Plain radiography showed oval calcified nodules at the level of C4-C5 and C5-C6. On computed myelography, oval calcified nodules were seen in the ligamenta flava of the posterior(More)
N-isopropyl-p[123I]-iodoamphetamine (IMP) single photon emission computed tomography (SPECT), X-ray computed tomography (X-CT) and magnetic resonance imaging (MRI) were performed in 18 children with idiopathic seizures. In children with idiopathic seizures SPECT identified abnormal lesions in the highest rate (50%) compared with X-CT (11%) and MRI (13%),(More)
Macromolecular Sn(II) complex (R-Sn) was developed using a chelating resin containing aminophosphonic acid groups as a reducing agent of 99Tcm(VII) in the preparation of 99Tcm radiopharmaceuticals. Since Sn(II) was bonded strongly to the resin by chelation, release of Sn from R-Sn was rarely observed in saline solution. 99Tcm labelling with a yield greater(More)
Forty-nine patients with acute spinal cord injuries were studied sequentially with MR imaging by using 0.5 Tesla superconductive units, and sequential MR changes were correlated with the prognosis of the patients. MR images were obtained within one week of the injury and then every two to six months when possible. The Frankel classification of neurologic(More)
The regional cerebral blood flow (CBF) was determined on seventeen patients with brain tumors. Ring type single photon emission CT (SPECT) was used following intravenous injection of 133Xe. Case materials included eleven meningiomas and six malignant gliomas. Evaluation was performed with emphasis on the following points; Correlation of the flow data within(More)
