Optimization of an MRI protocol for non-contrast saccule and utricle visualization at 1.5T

ISMRM Annual Meeting, 2023
This study evaluates the feasibility of different approaches for the visualization of endolymphatic content in inner ear structures on 1.5T MR systems without the need of contrast injection. The results show that using an optimized high-resolution 3D T2w sequence combined with DLR-based denoising tools it is possible to visualize the utricle and ...

Unilateral examination of utricle and saccule function

Journal of Vestibular Research, 2003
Attention is directed towards the recently developed unilateral tests of saccular and utricular function. Together with the now widely used head-thrust test and the standard caloric test for semicircular canal function, these provide for a more comprehensive unilateral examination of labyrinth function.

Otolith mass asymmetries in the utricle and saccule of flatfish

Journal of Vestibular Research, 2005
The otolith mass of the saccules and utricles of plaice, Pleuronectes platessa (n = 39) and turbot, Psetta maxima (n = 21) was measured using an electronic microbalance. In the right-eyed plaice, the left utricular otoliths were found to be significantly heavier than the right (p < 0.0001), whereas no significant difference was found between left ...

Morphometry of otoconia in the utricle and saccule of developing Japanese quail

Hearing Research, 2004
The development of otoconia in the utricular and saccular maculae from initial embryonic formation to adult stages was examined in Japanese quails. Both the morphology and size of the otoconia were quantified at different developmental stages. It was observed that the otoconia were initially formed on embryologic stage E5 in the saccule and E6 in the ...

The Effect of CO₂and KTP laser on the cat saccule and utricle

The Laryngoscope, 2009
AbstractObjectives/Hypothesis:To assess the potential carbon dioxide (CO2) and potassium‐titanyl‐phosphate (KTP) laser‐related trauma to the saccule and utricle in a cat model.Study Design:Basic science experiment utilizing cat model.Methods:Twelve adult male cats were divided into two groups—CO2and KTP—to assess the potential saccule and/or utricle ...

[A study of the otolithic membranes of the saccule and utricle of the guinea pig].

Kosmicheskaia biologiia i aviakosmicheskaia meditsina, 1990
By scanning electron microscopy the otolith membranes of the sacculus and utriculus of adult guinea-pigs were examined. The spatial arrangement of otoconia was found to differ from the standard scheme. New forms of imperfect otoconia were detected. Differences in morphological parameters of otoconia in the labyrinthine structures were revealed. Factors

[Three-dimensional morphological measurements of the utricle, saccule and stapes footplate].

Zhonghua er bi yan hou tou jing wai ke za zhi = Chinese journal of otorhinolaryngology head and neck surgery, 2011
To determine the optimal drill area on the footplate with the 3D measurements of the stapes and the vestibular end organs.Four temporal bones were extracted from the fresh cadavers and undecalcified polymer-embedded. After serially sectioning, image processing and the 3D precisely reconstruction, a local Cartesian coordinates was established in which ...

[Comparative morphology of the two type's hair cells from saccule and utricle under inverted phase contrast microscope].

Lin chuang er bi yan hou tou jing wai ke za zhi = Journal of clinical otorhinolaryngology head and neck surgery, 2011
To explore more reliable standards for identifying vestibular hair cells of saccule and utricle prepared in studies with patch clamp technique under inverted phase contrast microscope.The length and width of two type's hair cell's were measured besides the length of cilia, and all datas were analyzed statistically.The width and length of cilia of two ...
