[Examination of the pancreas using various imaging methods].

After presenting contemporary employed various imaging methods, the comparative evaluation of Ultrasonography and CT in examination of pancreas lesions is discussed. It was stressed that techniques mentioned above give comparable good results and that they are complementary. The authors pointed out that US is the first technique of examination of the gland and in many cases it enables the proper diagnosis, whereas CT is used when the result of US examination is doubtful. Standard scans were performed and interpreted in each patient before using US and CT examination. In cases still obscure a biopsy is indicated. The frequency of pancreas visualization is dependent not only on the quality of the equipment used, training of the investigator, correct determination of the pancreatic field, but also on the experience and cooperation of the team performing the investigation.

[Si vis pacem, para pacem instead of si vis pacem, para bellum].

In the article the danger of the nuclear war and its possible medical, biological as well as environmental consequences for the population of the whole world have been presented. War is determined by political, social and economic problems, but it need not be the only way of solving complex world conflicts. War is generated in human mind and it is only human mind which can prevent it. The world-wide organization called "International Physicians for the Prevention of Nuclear War" (IPPNW) was set up in 1981 to prove that it is better for the mankind to live in peace than to confront the nuclear peril. In case of the nuclear war health service would not be effective at all and the world's population should have no doubts about it. There is no doubt that the radiologists and other physicians, physicists working on radiation and other technical personnel are particularly responsible for popularizing in the society the knowledge of the basic physical facts and of the medical consequences of nuclear danger.

Value of CT and NMR imaging in diagnosing of chordomas.

Chordomas usually occur in the axial skeleton and they arise from the remnants of notochord. Their growth is slow and they often give metastases. Such cases are mainly observed among people above 40 years of age. Most frequently chordomas are situated in sacral bone (50%), in spheno-occipital region of the skull base (35%), and in the cervical, dorsal and lumbar spine (15%). Very rarely chordomas are found within sella, paranasal sinuses and nasopharynx, and in the forms of ectopic foci in the pons and spinal canal. Such tumour situated within spine destroys vertebral bodies and arches and can bulge into subdural space causing impression of the dural sac. Despite osteolytic destruction, chordomas cause visible reactive sclerotization and characteristic granular calcifications or ossifications. Intracranial chordomas destroy bony base of skull, specially clivus, pyramids and sphenoid sinuses.

[Diagnostic recognition of nucleus pulposus prolapse in light of clinical and radiologic correlations].

The authors compared the agreement between clinical, radiological and surgical diagnoses in 33 cases of nucleus pulposus prolapse. A complete agreement of diagnoses was obtained in 88% of cases. The mechanism and incidence of different signs and their importance for the diagnosis of nucleus pulposus prolapse are discussed. It should be stressed that the compression of nerve roots recognized on radiculography is not pathognomonic sign of prolapse and may be due to such processes as development of marginal osteophytes in the degenerative disc disease, thickening of the posterior longitudinal ligament, hypertrophy of radicular processes or necks of vertebral arches. In the light of own experiences and data from the literature the authors consider radiculography with Amipaque and computer tomography as the method of choice in cases with suspected disc herniation in the lumbar region.

[Radiologic diagnosis of consequences from head trauma].

In the light of the Lublin clinical center examinations and the literature data the author describes the roentgen-diagnostic methods used for recognition of the consequences of cranial injuries. The diagnostic effectiveness of different radiological techniques was compared. In cranial trauma without loss of consciousness no examination should be carried out. Skull films are of little use and may give a false safety, if no fracture is evident. Particular attention is paid to the importance of computed axial tomography in the diagnosis of various pathological conditions. It is revealed that a high agreement between the radiological results and the final clinical diagnosis in the patients with head injuries should be obtained only in the way based on a good cooperation between the radiologist and clinicians.

[Consideration of nuclear magnetic resonance imaging (NMR) in neuroradiology].

The purpose of the study was to present, on the basis of literature data, the possibility of examination of the central nervous system by means of magnetic nuclear resonance. Advantages and limitations of the method are described in cases of brain tumours, white matter diseases, parasitic diseases and vascular changes, inflammatory processes as well as dys-histogenesis. The main advantage of the method which will make its future use particularly wide-spread is the fact that it eliminates exposure to ionizing radiation, makes possible determination of the character of the tissue based on the content of hydrogen nucleus in a given area, and enables differentiation to be made of the tissues with different interatomic bonds, that is those which contain different chemical compounds. Diagnostic potential of computed tomography, ultrasonography, magnetic nuclear resonance, emission tomography and subtraction angiography have been compared. The hazards associated with clinical application of NMR technique are also discussed.
