[Use of three-dimensional reconstruction of the biliary tree in spiral computed tomography without using hepatotropic contrast media].

The aim of the study was to assess the quality of biliary tract imaging without cholangiographic contrast medium and to evaluate the usefulness of 3-D reformations in determination of ductal anatomic relationship. The spiral 5 mm CT liver scans were performed after a bolus of 150 ml i.v. contrast agent in 15 patients with a malignant obstructive jaundice. The biliary tract was separated from surrounding hepatic parenchyma with segmentation computer algorithm and then 3-D models were produced. In all the patients, both biliary anatomy and the localization and degree of segmental obstruction were visualized with satisfying quality. The 3-D sCT models of dilated biliary tract can be obtained without cholangiographic contrast agent and can clearly depict ductal anatomy and pathology.

[Virtual bronchoscopy: a new tool of non-invasive imaging of airway inner surface based on standard spiral computed tomography of the chest].

The aim of the study is to assess the new method of radiological imaging of the inner surface of a tracheobronchial tree in order to determine to what extend it can replace the standard bronchoscopy. The spiral CT examinations of 43 patients with hilar lung tumor in virtual mode had been reconstructed retrospectively and compared to the results of fiberoptic bronchoscopy. There was a significant correlation between both methods to reveal stenoses or occlusions of airway lumen. Virtual endoscopy turned out to be an unsatisfactory method in the visualisation of mucosal changes.

Patellar motion analyzed by kinematic and dynamic axial magnetic resonance imaging in patients with anterior knee pain syndrome.

Ten consecutive patients (12 knees), all women, with anterior knee pain syndrome participated in the study. The patellofemoral joints were examined with the knee in 0 degrees, 10 degrees, 20 degrees, and 30 degrees of flexion. At each knee position, kinematic and dynamic, an axial magnetic resonance (MR) image was used to focus on the sagittal plane, followed by an axial image focused through the middle of the patella. Ten healthy volunteers (20 knees) with no history of previous or current knee problems or anterior knee pain also underwent MRI scanning following the same procedure. Three angles were measured: patellar tilt angle (PTA), sulcus angle (SA), and congruence angle (CA). For statistical analyses, we used the Mann-Whitney U-test. Compared with the control knees, five patterns of malalignment were identified. The most frequently observed was tilt and lateralisation, with elevated CA and decreased PTA. In extension, the average CA for this group was 22 degrees and PTA -4.8 degrees vs -8.1 degrees and 14.3 degrees for control knees respectively. Contraction of the muscles caused tilt of the patella in symptomatic knees. This decrease of the PTA was statistically significant in extension (P < 0.05) and in 10 degrees of flexion (P < 0.05). Contraction of the thigh muscle increased CA in 30 degrees of flexion. This lateral pull was statistically significant (P < 0.05). There were no statistically significant differences of SA between the groups, regardless of muscle contraction or flexion angle. At 30 degrees of flexion, muscle contraction increased CA and decreased PTA. In our opinion, imaging in the first 30 degrees of flexion with thigh muscle contraction is necessary for a correct diagnosis.

[Acute poisoning by carbon monoxide affecting the extrapyramidal system].

A case record of a 19-year old women acutely poisoned by carbon monoxide is presented. The state of the patient was very serious with loss of consciousness, cerebral oedema and acute circulatory failure, manifested by pulmonary oedema. The presence of carboxyhemoglobin in concentration of 45% was found in the blood. During the second week after the incident, extrapyramidal symptoms, manifested by hyperkinetic-hypokinetic syndrome with predominant involuntary movement, was observed. The diagnostic examinations of the central nervous system showed necrosis of globus pallidus, external capsule and a part of internal capsule.

[Herpes simplex encephalitis in children].

Clinical course of Herpes Simplex Encephalitis were shown in this paper. 24 children in the age of 4 to 15 were treated at Polish Mother's Memorial Hospital in years 1992-1994. Value of EEG, CT scan, NMR were underlined in early diagnostic and casual treatment of diseases. All children from this analysis group survived, only 8 demonstrated late complications: epileptic attacks (3), spastic tetraparesis (1), encephalopathy and mental disturbances (1). Positive results of treatment were connected with early diagnosis and early antiviral treatment which is very important in decreasing death rate and preventing permanent injury.

[Functional magnetic resonance imaging in the assessment of motor centers in patients with brain tumors in motor area].

Magnetic resonance imaging (MRI) is become recognised as the most sensitive and specific imaging modality for the examination of central nervous system pathology. Blood oxygen level-dependent (BOLD) contrast imaging is a non-invasive functional MRI technique for localising active neuronal brain centres. The aim of our study was to determine usefulness of fMRI in detecting hand movements cortical activity in hemisphere with brain tumour and comparison with corresponding one. Six right-handed patients with brain tumours of central sulcus area, aged 20-50 years were examined using a commercial 1.5 T scanner. All patients underwent both conventional and functional magnetic resonance imaging (MRI) examinations. Simple hand movements were examined separately for right and left hand at a self-paced rate. Significant increase of signal intensity was found in: a) contralateral primary motor cortex in all cases during both motor tasks, b) ipsilateral primary motor cortex, supplementary motor cortex and premotor cortex of both hemispheres in a part of the cases c) displacement of the activity in the affected hemisphere in comparison to the opposite one was noticeable depending on the localisation and size of the tumour and accompanied oedema. Usefulness of functional MRI in detecting primary motor area in patients with brain tumours was proved. There is a difference between activation in affected cortex and corresponding normal cortex in the opposite hemisphere.

[Neurosonography-ultrasonography in diagnosis of the central nervous system].

Diagnostic possibilities created by ultrasound in the examination of CNS are discussed. Applications of neurosonography in relation to the diagnosis of brain and spinal cord diseases are listed. Emphasis is on ultrasound monitoring of cerebral biopsy enriching precise diagnosis of CNS.

[A case of favorable outcome of conservative treatment of acute otogenic cerebellar abscess].

The authors report a case of conservatively cured abscess in the left cerebellar hemisphere demonstrated by CT. The patient was admitted in serious condition to a neurotraumatology centre. After pharmacological treatment a quick improvement of patient's health was achieved and control CT examination during his stay in hospital and after discharge from hospital confirmed the relation between clinical improvement and regression of changes in CT. The presented case points to the possibility of conservative treatment of brain abscesses if the patient meets certain clinical criteria, and CT provides the possibility of repeated checking of the dynamics of intracranial lesion.

[Usefulness of trans-fontanel ultrasonography in the diagnosis of various pathological changes in the brain of infants. II. Evaluation of the width of cerebral ventricles and morphology of extra-cerebral fluid spaces].

The analysis of the morphology of the extracerebral fluid space and the assessment of the cerebral ventricles width were done on the ground of 200 ultrasound cerebral scans in infants with an open anterior fontanel. A classification of lesions according to their morphologic picture and the level of progression of disease is proposed.

[Usefulness of trans-fontanel ultrasonography in the diagnosis of various pathological changes in the brain of infants. I. Comparison of diagnostic value of USG and CT].

Diagnostic values of ultrasound and CT scan were compared in the group of 50 children with suspected pathologic cerebral lesions. On the ground of results obtained in the 2nd part of the study (118 children) an attempt was made to evaluate in which percentage of the unselected patients the CT scan might be left out and the diagnosis made only using the ultrasound examination.
