ABSTRACT
Computed tomography is the modality of choice in imaging of adrenal glands. Density measurements on images without contrast agent are essential for differentiation of adrenal masses. Application of spiral computed tomography for diagnostics of adrenal masses enables sensitive detection of small adrenal tumors and reliable density measurements by elimination of uneven breath-holds effect and minimization of partial volume effect. Tissue harmonic imaging in ultrasonography is a new technique, which enables visualization of abdominal parenchymal organs with higher tissue contrast with less artifacts and is especially useful in ultrasound imaging of difficult-to-image patients with high body weight. Further comparative research will enable to learn the advantages of using that technique in diagnostics of adrenal masses. Magnetic resonance imaging enables very accurate visualization diagnostics of adrenal masses. It is due to its inherent multiplanar imaging capabilities and high tissue contrast of soft tissues which enables very accurate visualization of anatomical structures in adrenal region. Introduction of new techniques of magnetic resonance imaging as chemical shift imaging and dynamic studies with paramagnetic contrast agent enables accurate differentiation of adrenal cortex adenomas from non-adenomas. In case of difficulties in adrenal diagnostics magnetic resonance imaging is often a problem solving examination in regard to other imaging techniques of adrenal region.

The purpose of our study was the evaluation of usefulness of Magnetic Resonance Angiography in diagnostic process in patients with arteriosclerosis of lower extremities and complications such as aneurysms and pseudoaneurysms. 105 patients were examined using 2D TOF method. We concluded the results were very similar as in radiological examinations. The MRA is a very helpful method in evaluation of constriction and occlusion of iliac and femoral arteries and aorta.

The aim of our study was to show the results of the Magnetic Resonance Angiography of pelvis and lower extremities. 21 patients with clinical signs of venous thrombosis were examined. The obtained results show the MRA is very useful in evaluation of venous flow.

In the base of bronchial asthma is a chronic inflammatory process which takes place in bronchial mucous membrane. The main cells of allergic reaction are: mastocytes., basophils, eosinophiles and others. There are many factors released from them in various periods of allergic inflammation. Evaluation of a concentration of these factors may be very usefull in diagnostic and treatment of bronchial asthma.
