Reconstructing the major skull myology of the giant stem‐amphibian Mastodonsaurus: A case study for early tetrapods

Journal of Anatomy, EarlyView.
We reconstruct the major cranial musculature of the giant stem amphibian Mastodonsaurus giganteus, revealing a differentiated jaw‐adductor system, a probable sesamoid pulley, and previously unrecognised muscles. This EPB‐based case study establishes an anatomical framework for modelling feeding in early tetrapods and supports interpretations of ...

Characterization of cardiac- and respiratory-driven cerebrospinal fluid motion based on asynchronous phase-contrast magnetic resonance imaging in volunteers

Fluids and Barriers of the CNS, 2017
Background A classification of cardiac- and respiratory-driven components of cerebrospinal fluid (CSF) motion has been demonstrated using echo planar imaging and time-spatial labeling inversion pulse techniques of magnetic resonance imaging (MRI ...

3D Analysis of Mandibular and Glenoid Fossa Responses to Bone‐Anchored Maxillary Protraction in Patients With UCLP

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Introduction Bone‐anchored maxillary protraction (BAMP) has been increasingly used to correct midface deficiency and Class III malocclusion in patients with unilateral cleft lip and palate (UCLP). However, its three‐dimensional (3D) effects on the mandible remain insufficiently explored.

Sex determination from foramen magnum parameters in Thai cadaveric donor

Forensic Science International: Reports
The foramen magnum (FM) occupies a well-protected position, making it particularly intriguing for forensic research. The necessity for methods to estimate sex from cranial fragments becomes evident when only a partial skull is available for ...

Two Cases of Arnold-Chiari Malformation with Respiratory Failure

European Journal of Case Reports in Internal Medicine, 2014
Arnold–Chiari malformation is defined as downward displacement of the brainstem and cerebellum through the foramen magnum. It has different clinical presentations and four subtypes.

Synthetic MRI from radiotherapy planning CT images for Head‐and‐Neck Cancer

Journal of Applied Clinical Medical Physics, Volume 27, Issue 11, November 2026.
Abstract Background Computed Tomography (CT) provides geometric accuracy and electron density information essential for radiotherapy planning; however, it offers limited soft‐tissue contrast. Magnetic Resonance Imaging (MRI) improves tumor visualization but introduces registration uncertainties when acquired separately from the radiotherapy planning CT

Gamma knife radiosurgery of meningiomas involving the foramen magnum

Journal of Craniovertebral Junction and Spine, 2010
Background: Foramen magnum meningiomas represent a challenging clinical entity. Although resection is performed for those with a mass effect, complete resection is not always feasible.
