SummaryWe have applied high-quality medical imaging techniques to study the structure of the human ankle. Direct volume rendering, using specific algorithms, transforms conventional two-dimensional (2D) magnetic resonance image (MRI) series into 3D volume datasets. This tool allows high-definition visualization of single or multiple structures for diagnostic, research, and teaching purposes. No other image reformatting technique so accurately highlights each anatomic relationship and preserves soft tissue definition. Here, we used this method to study the structure of the human ankle to analyze tendon-bone-muscle relationships. We compared ankle MRI and computerized tomography (CT) images from 17 healthy volunteers, aged 18-30 years (mean 23 years). An additional subject had a partial rupture of the Achilles tendon. The MRI images demonstrated superiority in overall quality of detail compared to the CT images. The MRI series accurately rendered soft tissue and bone in simultaneous image acquisition, whereas CT required several window-reformatting algorithms, with loss of image data quality. We obtained high-quality digital images of the human ankle that were sufficiently accurate for surgical and clinical intervention planning, as well as for teaching human anatomy. Our approach demonstrates that complex anatomical structures such as the ankle, which is rich in articular facets and ligaments, can be easily studied non-invasively using MRI data.
The heterozygosity for p.Ser250Phe may have influenced the clinical manifestations, given that the patient presented some overlapping symptoms with those in AADCD, but while AADCD normally is diagnosed during childhood, the fact that the patient carried the mutation in heterozygosity may have alleviated and delayed the clinical manifestations.
Cranioplasty is the main surgical intervention for repairing cranial defects performed in about 80% of the patients following cancer surgery or decompressive craniectomy. Although some works have shown recovery of motor and cognitive function, including memory, attention, and executive functions, until today no studies have focused on language recovery after cranioplasty. A 68-year-old woman came to the Neurorehabilitation Unit of the IRCCS Neurolesi (Messina, Italy) because of a fluent aphasia due to a severe left nucleocapsular hemorrhage and greatly improved her motor and neuropsychological status after cranioplasty. Results confirmed that cranioplasty might significantly improve motor and neuropsychological function, besides aphasia. Healthcare professionals involved in rehabilitation should be aware of the potential role of cranioplasty in improving rehabilitative outcomes to better plan a more personalized rehabilitative program. Moreover, rehabilitation nurses can play a pivotal role within the rehabilitation process, as they are educated to interact and communicate with the patient suffering from aphasia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
