BACKGROUND Micro-computed tomography (micro-CT) offers significant potential for identifying mineralized structures. However, three-dimensional (3-D) micro-CT of alveolar bone has not been adapted readily for quantification. Moreover, conventional methods are not highly sensitive for analyzing bone loss or bone gain following periodontal disease or reconstructive therapy. The objective of this ...

BACKGROUND Micro-computed tomography (micro-CT) is a novel tool for monitoring acute and chronic disease states in small laboratory animals. Its value for assessing progressive lung fibrosis in mice has not been reported so far. Here we examined the importance of in vivo micro-CT as non-invasive tool to assess progression of pulmonary fibrosis in mice over time. METHODS Pulmonary fibrosis was...

re-preparation with rotary or reciprocating files and passive ultrasonic irrigation (PUI). Twenty maxillary molars were prepared using ProTaper instruments up to F1. The teeth were filled with AH Plus and ProTaper gutta-percha points using the single-cone technique. Thereafter, the specimens were scanned using a micro-computed tomography system (Micro-CT #1). Then, the root canal filling was re...

STUDY DESIGN The micro-computed tomography (micro-CT) was applied to assess the effect of tetramethylpyrazine (TMP) on experimental spinal cord injury (SCI). OBJECTIVE The aim of the study was to explore the therapeutic effect of TMP on a rat SCI model using micro-CT. SUMMARY OF BACKGROUND DATA SCI is a devastating event and always accompanied by severe vascular injury. Promoting angiogenes...

Aims The X-ray micro-tomography (micro-CT) technique has been used to visualize the microstructure of pharmaceutical granules produced by high shear wet granulation and the dynamic evolution of porosity during granule dissolution. The combination of time-resolved micro-CT imaging with UV/VIS detection of the quantity dissolved made it possible to evaluate the effective diffusion coefficient of ...

Micro Computed Tomography (Micro CT) is an advanced imaging modality based on multi slice x ray images which allows three dimensional reconstructions of the viewed structures. This review highlights the significance of micro CT, its working principle and also throws light on its advantages and limitations over conventional 2D radiography as well as Cone beam Computed Tomography. This review als...

The study of dual-modality technology which combines microcomputed tomography (micro-CT) and fluorescence molecular tomography (FMT) has become one of the main focuses in FMT. However, because of the diversity of the optical properties and irregular geometry for small animals, a reconstruction method that can effectively utilize the high-resolution structural information of micro-CT for tissue ...

In order to understand and to simulate the functional behaviour of porous structures during loading, quantitative knowledge of the relationship between the morphology and the mechanical behaviour is necessary. Therefore, the porous structures need to be quantified morphologically. In this research, the quantification will be performed by using micro-CT. However, to date, this technique encounte...

OBJECTIVES The objective of this study was to identify an injection strategy leading to repeatable nanoparticle deposition patterns in tumours and to quantify volumetric heat generation rate distribution based on micro-CT Hounsfield unit (HU) in magnetic nanoparticle hyperthermia. METHODS In vivo animal experiments were performed on graft prostatic cancer (PC3) tumours in immunodeficient mice...

Context Root canal anatomy is evaluated using different methodologies. Aims The aim of this study is to evaluate and classify root canal morphology and dentin thicknesses (DT), comparing radiographic and micro-computed tomography (CT) analysis. Materials and Methods Canal diameter and DT of mandibular incisors (n = 520) were evaluated using digital radiographs in buccolingual (BL) and mesio...
