چکیده

We present CT and MR imaging studies of a histologically proved case of a primary intraaxial amyloidoma of the brain. Noncontrast CT and T1-weighted MR images revealed increased density and hyperintensity respectively of amyloid tissue. There was mixed intensity on proton-density and T2-weighted sequences, and marked contrast enhancement was demonstrated on both modalities.

CT and MR imaging of intracerebral amyloidoma: case report and review of the literature.

Intracerebral amyloidoma is the least common form of amyloid deposition in the brain. CT and MR imaging features in a case of pathologically proved cerebral amyloidoma are presented, and the available literature is reviewed. Typical imaging features of this entity include solitary or multiple supratentorial white matter masses that are hyperattenuated on nonenhanced CT. They have little or no m...

Generating the synthetic CT (sCT) and synthetic MR (sMR: sT1w/sT2w) images of the brain using atlas based method

Introduction: Radiation therapy planning (RTP) is one of the clinical applications in which both CT scan and MRI are used. MR and CT images are applied to determine the target volume and calculation of dose distribution, respectively. In addition, using two imaging modalities increases the department workload and cost. In this study, an algorithm was presented to create synthet...

Primary amyloidoma of the cervical spine.

Primary solitary amyloidoma of the spine is a disease characterized by localized deposits of amyloid. We describe and illustrate the radiologic appearance of primary solitary amyloidoma of the spine on plain radiographs, CT scans, and MR images. The imaging findings revealed features of a nonspecific soft-tissue mass with calcifications. Epidural extension of the amyloidoma caused spinal cord c...

Generating Synthetic Computed Tomography and Synthetic Magnetic Resonance (sMR: sT1w/sT2w) Images of the Brain Using Atlas-Based Method

Introduction: Nowadays, magnetic resonance imaging (MRI) in combination with computed-tomography (CT) is increasingly being used in radiation therapy planning. MR and CT images are applied to determine the target volume and calculate dose distribution, respectively. Since the use of these two imaging modalities causes registration uncertainty and increases department w...

Comparison of state-of-the-art atlas-based bone segmentation approaches from brain MR images for MR-only radiation planning and PET/MR attenuation correction

Introduction: Magnetic Resonance (MR) imaging has emerged as a valuable tool in radiation treatment (RT) planning as well as Positron Emission Tomography (PET) imaging owing to its superior soft-tissue contrast. Due to the fact that there is no direct transformation from voxel intensity in MR images into electron density, itchr('39')s crucial to generate a pseudo-CT (Computed Tomography) image ...
