For the purpose of increasing informativity of X- ray methods in using them in the diagnosis of large intestine diseases including the differential diagnosis of nonspecific ulcerative colitis and Crohn disease 27 patients with the given diseases were examined using a modified method-computer tomography with intraenteric contrasting. The computer-tomographic sighus characteristic for colitis and Crohn dicease are established.

Inflammatory Bowel

Inflammatory bowel disease (IBD) is composed of two major subtypes, ulcerative colitis (UC) and Crohn disease (CD). These chronic disorders, characterized by inflammation of the gastrointestinal tract, demonstrate a variety of clinical features, including intestinal and extraintestinal manifestations during periods of relapse and remission over many years. This review examines the clinical features of IBD, including the extraintestinal manifestations and diagnosis. Figures include examples of images conducted via computed tomography (CT), magnetic resonance imaging, and position emission tomography (PET)/CT. Tables list the location frequencies of UC and CD at the time of diagnosis, extraintestinal manifestations of IBD, differential diagnosis of UC and CD, and clinical utility of fecal calprotectin in the evaluation and management of IBD. This review contains 4 highly rendered figures, 5 tables, and 48 references.

Quantitative Characteristics

The article presents results of assessing lung parenchyma density within X-ray diagnostic pattern “Opal glass” in patients with changes characteristic for occupational hypersensitivity pneumonitis(60 patients) and interstitial pneumonia (65 patients of reference group) vs. reference group (70 individuals), by modified method of X-ray computer tomography of high resolution. Quantitative characteristics as native parameter (HU units), density gradient (IDG), with consideration of homogeneity degree of the evaluated zone by SD value enabled considerable objectification of the changes direction in diagnostic monitoring of the studied lung disorders.

Ileocecal Junction

The colon is made up of the midgut which includes the proximal two-thirds of the transverse colon, and the hindgut, which includes the distal one-third of the transverse colon. The ileocecal junction to the anus is a distance of 1.5 m. Digested food (chyme) passes into the colon and is converted to feces by bacteria. The differential diagnosis of colonic masses includes cancer, carcinoid, lipoma, diverticular disease, ulcerative colitis, polyps, and Crohn disease. Treatment of colorectal cancer and symptomatic inflammatory colon disease usually involves wide surgical resection. Complications after surgery may include postoperative bleeding, leakage, and ileus.

Specific Symptoms

Pneumatosis cystoides intestinalis is a rare disease characterized by presence of multilocular cysts in the gastrointestinal wall. Idiopatic and secondary forms of the disease can be distinguished. There are presented several theories explaining pneumatogenesis in this article. The specific and non-specific symptoms are described. Attention is drawn to the pneumoperitoneum without signs of peritoneal irritation, what is a typical complication of this disease. The suspition of pneumatosis cystoides intestinalis may be based on plain abdominal X-ray, and is usually confirmed by computer tomography or magnetic resonance imaging. The therapy can be conservative or surgical. In conclusion, although pneumatosis cystoides intestinalis is a rare disease, it may represent a problem in differential diagnosis of abdominal pain.

The aim of the study was to investigate the effect of X-rays used in micro X-ray computer tomography (µXCT) on the mechanical performance and microstructure of a variety of dental materials. Standardised bending beams (2 × 2 × 25 mm3) were forwarded to irradiation with an industrial tomograph. Using three-dimensional datasets, the porosity of the materials was quantified and flexural strength was investigated prior to and after irradiation. The thermal properties of irradiated and unirradiated materials were analysed and compared by means of differential scanning calorimetry (DSC). Single µXCT measurements led to a significant decrease in flexural strength of polycarbonate with acrylnitril-butadien-styrol (PC-ABS). No significant influence in flexural strength was identified for resin-based composites (RBCs), poly(methyl methacrylate) (PMMA), and zinc phosphate cement (HAR) after a single irradiation by measurement. However, DSC results suggest that changes in the microstructure of PMMA are possible with increasing radiation doses (multiple measurements, longer measurements, higher output power from the X-ray tube). In summary, it must be assumed that X-ray radiation during µXCT measurement at high doses can lead to changes in the structure and properties of certain polymers.
