3 sie 2016 · The cross-sectional imaging modalities available include computed tomography (CT), magnetic resonance imaging (MRI), ultrasound (US) and positron emission tomography-computed tomography with fluorine-18-deoxy-D-glucose (18 FDG PET-CT). Each modality has its own strengths and weaknesses; these are enumerated below.
3 paź 2019 · In this temporal bone study, we focused on high-resolution imaging of the human cochlea. The cochlea was approached through mastoidectomy and posterior tympanotomy, both standard surgical...
1 lis 2023 · Cross sectional imaging with CT and MRI may demonstrate IEM in 30% to 60% of SNHL cases.4,5 Adequate knowledge of the anatomy, embryology, and typical imaging appearance of IEM facilitates timely and appropriate treatment, which can help prevent later developmental complications.
30 paź 2020 · Dynamic contrast-enhanced MRI perfusion imaging can be of value in detecting and quantifying a microvascularity within tissue, providing characterization for head and neck cancers. This is used to generate blood flow, blood volume, and transit time parameters within areas of interest, and may help in assessing the histological grade of tumors.
MRI is generally the cross-sectional study of choice for tumours of the suprahyoid neck, although local operational policy will dictate its role in imaging the various tumour sites. Multislice computed tomography (MDCT) may be used to acquire a rapid, high spatial resolution volume of data.
14 cze 2024 · Purpose: Imaging of the delicate inner ear morphology has become more and more precise owing to the rapid progress in magnetic resonance imaging (MRI).
8 sty 2023 · The mean size and shape of the cochlea, as well as its cross-sectional analysis along the spiral, can provide important information for determining the optimum diameter and length of the electrode array, leading to better hearing outcomes for patients.
