BACKGROUND The inferior alveolar nerve courses anteriorly within the mandibular canal, providing sensory nerve supply to the mandibular teeth, the buccal mucosa, the gingiva, and the soft tissues of the lower lip and chin. To avoid damage to this nerve and resulting sensory disturbances, its exact location must be known before placement of a dental implant. Imaging modalities currently used to ...

BACKGROUND Our laboratory has been conducting positive control studies to evaluate the utility of micro-computed tomography (micro-CT) for qualitative evaluation of fetal skeletal morphology. All-trans-retinoic acid (atRA) was used to produce a different spectrum of defects compared to our previous studies with boric acid and hydroxyurea. METHODS Groups of five mated Crl:CD(SD) female rats ea...

BACKGROUND Shape of the dental root canal is highly patient specific. Automated identification methods of the medial line of dental root canals and the reproduction of their 3D shape can be beneficial for planning endodontic interventions as severely curved root canals or multi-rooted teeth may pose treatment challenges. Accurate shape information of the root canals may also be used by manufact...

PURPOSE To evaluate airway changes in ovalbumin-induced asthmatic mice in terms of postmortem micro-CT images and pathological findings. METHODS Asthma was induced in mice by intraperitoneal injection and nasal instillation of ovalbumin aluminium hydroxide into mice (experimental group, n=6), and another group of mice received intraperitoneal injection and nasal instillation of distilled phos...

PURPOSE Ischemia-reperfusion injury (I/R) is a common early complication after lung transplantation. The purpose of this study was to compare ultrashort echo-time (UTE) sequences in magnetic resonance imaging (MRI) with a microcomputed tomography (micro-CT) reference standard for detection of I/R injury in a lung transplantation mouse model. MATERIALS AND METHODS Six mice (C57BL/6) underwent ...

Porosity of polypropylene samples was investigated by applying X-ray micro-computed tomography (micro-CT), which is getting more and popular as a non-destructive method. Microspheres were applied blowing agent at three concentrations: 3%, 6% 9% weight. Tensile testing specimens obtained injection molding technology its central, measuring part examined micro – CT. Results compared to porosity ca...

The taxonomic status of some mainland Southeast Asian Coeliccia species is evaluated. The following synonymies are presented: C. acco is a junior synonym of C. pyriformis; C. tomokunii that of C. scutellum; C.onoi that of C. cyanomelas. C. scutellum hainanense is promoted to species level, C. hainanense. Redescriptions of the holotype of C. pyriformis and of the lectotypes of C. scutellum and C...

Aims Early reports of micro computed tomography (micro CT) of urinary stones showed non-overlapping ranges of x-ray attenuation values for most minerals. However, extended work in our laboratory has shown that size of stone fragments and scanning parameters can each influence the apparent x-ray attenuation value of minerals. The purpose of the present study was to test the correlation of minera...

Aims In preclinical setting, micro-CT is used to provide anatomical information of small animals (e.g. mice), and can be used in conjunction with functional imaging modalities, which provide information on biological processes in tissues. The combination of micro-CT with functional imaging provides localization of the investigated process, i.e. physiology or disease, within the animal and furth...
