A vendor-neutral MR bone imaging technique based on 3D time-of-flight MR angiography with spoiled gradient recalled acquisition in the steady state (TOF-SPGR) was developed to enhance the depiction of bone and calcification/ossification. This approach is independent of scanner manufacturer and application type, enabling reduced radiation exposure by replacing or triaging further CT examinations. This article describes the optimization of scan parameters for clinical musculoskeletal protocols and explores its clinical applications with representative cases.

Midsagittal ultrasound images depict much of the tongue surface from root to tip, providing important articulatory information about tongue shape. However, portions of the tip can be obscured due to shadowing from the mandible bone and sublingual airspace. Also, tongue curvature or grooving within the elevational beam width can cause ambiguous or double-edge artifacts that obfuscate the midsagittal tongue surface.

Accidental displacement of impacted and non-erupted upper third molars into the maxillary sinus, buccal space, infratemporal fossa, and lateral pharyngeal space is uncommon. Herein, we present an unusual case of parapharyngeal cellulitis secondary to iatrogenic displacement of the right third molar. Clinical history, physical examination, and imaging assessment are essential in the evaluation of teeth projected into adjacent anatomic spaces.

Background: Schizophrenia patients with auditory hallucinations have distinct morphological abnormalities, but whether this population have a progressive gray matter atrophy pattern and specific transmission chain of causal effects remains unclear. This study was designed to construct a causal structural covariance network in schizophrenia patients with persistent auditory hallucinations.
Methods: T1-weighted MRI images were acquired from 90 schizophrenia patients with persistent auditory hallucinations (pAH group) and 83 healthy controls (HC group).

Purpose To evaluate the performance of a delayed-phase dynamic contrast-enhanced (dDCE) MRI model in quantitative assessment of myocardial tissue physiology and late gadolinium enhancement (LGE) within 5 minutes after contrast material injection in reperfused myocardial infarction (MI). Materials and Methods This animal study included 11 canines (seven female) with reperfused MI. A dDCE model using dynamic postcontrast T1 maps was adopted to depict an unbiased contrast material washout process.
