[Imaging is important in the evaluation of tumour detection, staging to determine the response to therapy, to follow the patient to find an early recurrent tumour. The ability to assess cancer spread has been revolutionized by advances of digital imaging modalities, such as digital ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI). MRI is the method of choice for detecting and evaluating brain, spine, head and neck and musculoskeletal tumours, but it is complementary in the investigation of the thorax. US and CT remains the primary test for imaging the abdomen, while MRI plays a subsidiary role as a problem solving technique. In the evaluation of focal liver disease numerous prior reports have documented a superior performance of MRI compared to CT and US in the detection of primary and metastatic liver tumours. MRI is gaining more and more importance in imaging of the pelvis. Breast MRI is increasingly used as an adjunct to conventional imaging modalities. Several recent developments in MRI have altered the role of this imaging, and it is often the preferred choice among diagnostic tools for the detection and characterization of tumour cases.]

[A report is given about two children with post-traumatic ischemic stroke. In the first case a blunt head injury, in the second case a minor cervical trauma caused the ischemic cerebrovascular episodes. The diagnosis was made after repeated CT scans by the help by sonography. The possible traumatic origin of acute hemiparesis due to ischemic stroke in children is emphasized. ]

[During his long practice as head physician of a neurological and psychiatrical department with over 100 beds performed the examination and department of more than a hundred thousand patients. Based on the acquired experience and the data of the most recent literature he treats every aspect of the apathy syndrome. He emphasizes the multidisciplinary approach during both establishing the causes and the examination and treatment of patients. In order to clarify the diagnosis consultations with other disciplines must be used as well as the the knowledge provided by the now essential CT, MRI, PET, SPECT. The author discusses the international therapeutical possibilities and practice after the recently alredy possible exact diagnosis.]

Aneurysm clips made of titanium alloy were considered to be useful for clinical application due to the expected reduction in artifact formation on postoperative CT and MR. First, the behaviour of the new titanium clip (Aesculap) was investigated in phantom experiments in CT and MR scanners. After the in vitro tests had proved the applicability of the new implants, a series of operations was performed employing the new clip in 21 patients and the traditional phynox clip in 17 patients. All patients with a titanium implant had postoperative 11, T2 and proton-weighted MR scans. In 12 cases pre- and postoperative; in 9 cases only postoperative MR angiographies were carried out. In 4 patients both control MR- and catheter angiographies were performed. Clinical results as analysed at least 6 months following the operation were not different from those of 1992 and 1993 of the same team and were comparable to recently published data in the literature. The study has shown that ability to effectively diagnose clip-adjacent brain structures can be improved considerably by employing clips of titanium alloys. Concerning the value of postoperative MR angiography either with or without contrast material to control the effectiveness of aneurysm occlusion, the following conclusion was drawn: while the postoperative potency of the parent artery was clearly visualized in every case, it was impossible to define whether occlusion of the aneurysm had been complete.

[Operability of lung cancer is based on the size and local extension of the tumor as well as the presence of lymph node and distant metastases. Agreement and disagreement between CT and surgical tumor staging was investigated for 197 cancer patients after surgery. Sensitivity and specificity of CT prediction ranged 57–93% and 71–100% ac cording to tumor stadium. CT diagnosis has been relatively unreliable in describing tumor propagation along the pulmonary veins (less frequently arteries) towards the atrium and in recognizing a discrete tumor invasion of the mediastinum. Local thickening of the parietal pericardium, and small pericardial effusion have been considered as indirect signs of pericardial tumor infiltration. MR examination have been found to be a supplemental technique for assessing tumor spread to the great vessels of the mediastinum. The authors believe on the results that new techniques, such as MR angiography and indirect CT signs will help in making a more accurate preoperative diagnosis of lung cancer.]
