AbstractIntroduction. Physiological intracranial calcifications have an increasing prevalence with the age and can be found in both children and in adults. These calcifications are basically asymptomatic and their presence can only be noticed through neuro-imaging.The aim of the paper was to evaluate physiological intracranial calcifications in children using computed tomography, in our conditions.Materials and methods. The study was designed as a retrospective, observational, non-randomized clinical study. It was conducted at the Department of Radiology, Clinical Center Kragujevac, Serbia. The study included all the patients scanned by CT from 1st October, 2008. to 30th September, 2018.. The criteria for the inclusion were: the patients aged up to 18 years who underwent a non-contrast computed tomography in the observed period, with diagnosed intracranial calcifications that do not have pathological etiology.Results. Our study included 420 patients. Out of them, 213 (50.7%) were boys and 207 (49.3%) were girls. The mean age was 12.47. We divided the patients into two age categories: the first one included the patients aged 1 to 10 years and the other one included the patients aged 11 to 18 years. Our study has demonstrated that physiological intracranial calcifications are the most frequent in habenula (28.1%), followed by the pineal gland (22.6%) and choroid plexus (18.8%).Conclusion. There is a small number of studies with the subject of physiological intracranial calcification distribution, especially in children. It is important to know in which locations we can expect physiological intracranial calcifications, as well as the age in which they become detectable by imaging, in order not to mix them with hemorrhages, pathological tumor or metabolic mineralization.

Pulmonary arterial and intracranial calcifications are rarely found in children. A female infant, the recipient of a twin–twin transfusion syndrome was found, by ultrasound and computed tomography, to have both pulmonary arterial and intracerebral calcification. A rare condition, termed idiopathic arterial calcification of infancy, is the likely cause. This condition carries a poor prognosis and is usually fatal.

Neurofibromatosis Type 2 (NF2) is a genetic disorder associated with schwannomas, meningiomas, and ependymomas. Intracranial calcifications, either tumoral or non-tumoral, are relatively lesser known features of NF2. Here, we present a case of NF2, in which the diagnosis was suspected due to the presence of choroid plexus and subependymal calcifications, although no obvious schwannoma or meningioma was detected initially on standard computed tomography or magnetic resonance imaging. This case highlights the importance of further evaluation with appropriate imaging techniques.

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.
