Background Venous malformation (VM) is a common vascular malformation in soft tissue. Surgical management plays an important role in its treatment. The location, extent, and adjacent anatomy of the lesion are crucial information for the safety of operation. This study introduces the application of magnetic resonance imaging and percutaneous sinus angiography/three-dimensional computed tomography imaging in gathering above information. Methods A retrospective analysis was made in the patients with venous malformation from January 2012 to June 2014 in our clinic. All patients underwent magnetic resonance imaging and percutaneous sinus angiography/three-dimensional computed tomography imaging. The location, extent of the lesion, its draining veins, and the relationship with around tissues were showed. Surgical management was carried out in the lesions which were well defined, located in the superficial fascia without important vessels and nerves across it. The wound was repaired by skin flap or skin graft. Results A total of 13 patients underwent complete surgical removal of the lesions, including five type I venous malformations and eight type II venous malformations. Ten lesions were removed by undermining dissection, and the wound was repaired by the undermined flap. Three superficial lesions were removed together with the skin over it, and the wound was repaired by the skin graft. In the six months to two years of follow-up period, none of the recurrence of the lesion was observed. Conclusion Magnetic resonance imaging and percutaneous sinus angiography/three-dimensional computed tomography imaging can display abundant morphological details of venous malformation, which are helpful for the surgical management.

Introduction: Maxillary canines are usually impacted teeth the second after third molar. Frequency of impacted maxillary canines is about 1 to 3% of population (in 85% of the cases palataly, and in 15% of the cases bucaly). The aim of this research was to find the frequency of bucal and palatal impacted maxillary canines in relation to sex and position of impacted tooth. Matherial and method: We analyzed three-dimensional computed tomography images (CBCT) of 64 examinees (aged 12 to 33 years) with 80 unerupted maxillary canines to plan the orthodontic therapy. Results: Among 64 examines with impactions, 80 impacted maxillary canines are diagnosed. The average age of all respondents in the survey is 16,3±4,3. Of 64 examinees in research 41(64.1%) were female which is significantly more important than the representation of male examinees whose number was 23(35.9%). Frequency of unilateral impactions of maxillary canines is three times higher 48 (75%) in comparison to bilateral impactions 16 (25%). Of total 80 impacted maxillary canines 19 (23.75%) were bucal impacted, 3 (2.75%) in the middle of alveolus and 58 (72.5%) palatally. With the bucal and palatal impaction usually was represented partially vertical impaction (70%); completely horizontal impaction (10%) was represented only in the palatal impaction. Conclusion: The analysis of CBCT images of maxilla shows a statistically significant frequency of partially vertical, unilateral and paltally localized impacted maxillary canines.

Three Dimensional Images

We have developed a new X-ray microscope which produces complete three dimensional images of samples. The microscope operates by performing X-ray tomography with unprecedented resolution. Tomography is a non-invasive imaging technique that creates maps of the internal structure of samples from measurement of the attenuation of penetrating radiation. As conventionally practiced in medical Computed Tomography (CT), radiologists produce maps of bone and tissue structure in several planar sections that reveal features with 1mm resolution and 1% contrast. Microtomography extends the capability of CT in several ways. First, the resolution which approaches one micron, is one thousand times higher than that of the medical CT. Second, our approach acquires and analyses the data in a panoramic imaging format that directly produces three-dimensional maps in a series of contiguous stacked planes. Typical maps available today consist of three hundred planar sections each containing 512x512 pixels. Finally, and perhaps of most import scientifically, microtomography using a synchrotron X-ray source, allows us to generate maps of individual element.
