Right juxtacondylar bony facet on the basiocciput: a proatlas segmentation variant
نویسندگان
چکیده
Introduction Bony variations related to failure of segmentation of most caudal of the occipital sclerotomes, the pro-atlas, are rare, but have been documented [1]. The developmental failures lead to unusual bone formation at the anterior rim of foramen magnum, either in midline or laterally. Developmental osseous anomalies of the cranio-vertebral complex can result in neural compression, vascular compromise and disturbed orthokinetics.

Canalis basilaris medianus and related defects of the basiocciput.
Anatomic variants and developmental defects of the basiocciput are uncommon. The best known include transverse segmentation , longitudinal segmentation, "key-hole defect," and canalis basilaris medianus (CBM). Transverse segmentation [1-3] may be complete or incomplete. In the complete form the basiocciput is divided by a transverse fissure into an anterior part, sometimes called os basioticum,...

E-mail: [email protected] Abnormalities of the craniovertebral junction are of great interest not only to anatomists but also to clinicians, because many of these malformations can produce neurological symptoms and death. Median occipital condyle is presented in...
متن کاملComparing 511 keV Attenuation Maps Obtained from Different Energy Mapping Methods for CT Based Attenuation Correction of PET Data
Introduction: The advent of dual-modality PET/CT scanners has revolutionized clinical oncology by improving lesion localization and facilitating treatment planning for radiotherapy. In addition, the use of CT images for CT-based attenuation correction (CTAC) decreases the overall scanning time and creates a noise-free attenuation map (6map). CTAC methods include scaling, s...
