Abstract
Magnetic resonance imaging of amputated human knees was performed to determine optimal sequences for depicting articular cartilage. 24 knees were examined with eight different sequences in a 1.0 T imager. Each cartilage lesion was graded from 1 to 4 (Outerbridge staging system). The results of each sequence were compared with the macroscopic findings and statistically tested against each other. The FLASH sequence (TR = 50 ms) with combination of flip angle of 40 degrees and echo time of 10 ms and the FISP sequence (TR = 40 ms) with combination of flip angle of 40 degrees and echo time of 11 ms were best for depicting cartilage structure and internal detail. There was no significant difference between fat-saturated three-dimensional FLASH (FS-3D-FLASH) and FS-3D-FISP (p = 0.05). These FS-3D sequences were significantly better than sequences without fat saturation (p = 0.05). There was no significant difference between magnetization transfer (MT) 3D-FLASH, MT-3D-FISP and 3D-FISP. All 3D sequences showed significantly (p = 0.05) better results than spin echo or fast spin echo sequences. The T1 weighted SE pulse sequence was significantly (p = 0.005) better than the T2 weighted TSE sequence. Fast T2 weighted spin echo was not suitable for early and accurate detection of cartilage lesions.

Abstract
PURPOSE Shoulder lesions are usually examined with the joint in only one or two positions. We examined the shoulder with the joint in a variety of positions. We also assessed the application of cine-MR to the detection of instability and impingement. MATERIAL AND METHODS The cine-MR examinations were performed in 30 patients and 15 healthy volunteers. We used an open 0.2 T system and a closed 1.0 T system. Spoiled gradient echo 2D T1-weighted images and turbo spin-echo T1- and T2-weighted images were obtained with a field of view of 180 mm. The examinations were videotaped and evaluated later. RESULTS Normal variations of the glenohumeral joint were easy to recognize. Sub-luxations and luxations of the humeral head as well as rupture of the labrum were identified. It was also possible to identify the labrum with a signal change after arthroscopic refixation. And we were able to objectively assess distances between the osseous structures during dynamic movement. CONCLUSION Unlike static MR, cine-MR would appear to be useful in visualizing the capsular ligament complex of the gleno-humeral joint in impingement and instability. It also provides information on dynamic changes and may thus prove to be an important tool for shoulder diagnostics. The method may provide an early diagnosis in the sub-acromial impingement syndrome.

Abstract
OBJECTIVE Investigations were conducted regarding changes of carpal tunnel shape during wrist motion and the variations of space for the median nerve as well as the preoperative signs of carpal tunnel syndrome (CTS) and the postoperative restitution. METHODS Axial MR images (1.0 T) were performed at the level of the distal radioulnar joint, pisiforme bone and hook of hamate level of 20 wrists of patients with clinical symptoms of CTS and further 20 wrists of volunteers. This was conducted with the wrist in neutral position, 45 degrees extension and 45 degrees flexion. T2-weighted signal intensity of the median nerve were measured in 18 patients pre- and postoperatively. RESULTS The increase of the cross-sectional area of the median nerve at the pisiform level and the flattening of the median nerve at the hook of hamate level as well as the volar bowing of the flexor retinaculum at the pisiform and hook of hamate level were significantly greater in patients with CTS than in those with normal wrists (P < 0.05-0.001). In postoperative follow-up studies the distal flattening of the median nerve recovered in 94%. The signal intensity of the median nerve on T2-weighted images decreased in 67%. CONCLUSIONS Flexion at the pisiform and hamate level as well as extension at the pisiform level narrows the space available for the median nerve potential leading to compression of the median nerve. MR imaging is accurate and reliable for diagnosis and postoperative follow-up of CTS.

Abstract
An important task for the forensic toxicologist and expert witness is the detection of the noxa in biological matrices. Because of this, the identification and quantification of residues of illegal drugs in human hair is still of growing interest. Utilizing the advantages of GC/MS/MS testing human hair is performed for most common drugs of abuse like heroin and other opioides, cocaine, cannabis and amphetamine derivatives. Analyzing hair specimens for substances that present a toxicological risk is another challenge. Several quality control parameters must be observed to avoid false positive or false negative results and to gain additional information. Blank sample, blank hair as well as the combined wash extracts are tested for the presence of the relevant compounds within every series. Careful evaluation of the findings can provide an approximate measure of the intensity of drug use in the majority of cases.

Abstract
Thromboembolic disorders are frequent complications in pediatric patients and the incidence seems to rise. Adult guidelines for thromboembolism do not hold for children because there are many age-related features. Congenital prethrombotic disorders play a major role in the pediatric population and activated protein C (APC) resistance is also the most frequently encountered problem. Acquired risk factors in children are central venous line thrombosis with serious complications, cardiac diseases such as cardiomyopathies, prosthetic heart valves and aneurysms, renal vein thrombosis, and nephrotic syndrome. Renal vein thrombosis primarily affects newborns. Children with the antiphospholipid antibody syndrome also have thromboses although less frequent than adults, but systemic lupus erythematosus is associated with a high incidence. Acute lymphoblastic leukemia is frequently associated with thrombosis in children, especially when complicated by APC resistance. The greatest risk of thrombosis in children is during the neonatal period, and again congenital prethrombotic states and catheter placement play a major role. The clinical manifestations in children reflect the site of the thrombosis and extensive laboratory evaluations and advanced diagnostic procedures must be employed to diagnose the thrombotic events.

Abstract
Fentanyl and sufentanil are potent narcotic analgesics used only in hospitals as anaesthetic agents. The dependence potential of fentanyl is known. As they are given in doses at the microgram level and their elimination half-life is in the order of a few hours, detection in body fluids is possible only for a short time after administration. Radioimmunological methods are the only ones capable of detecting fentanyl in hair, as normal GC/MS methods for hair analysis are not sensitive enough to detect the drugs after doses in the order of micrograms. We therefore chose GC/MS/MS to analyse fentanyl and sufentanil in two cases where the drugs were given under controlled conditions over several days. The concentration was in the order of less than 100 pg/mg hair.

Abstract
Hoffa fracture is a rare injury consisting of unicondylar tangential posterior fracture of the distal femur. On plain radiographs the fracture line is clearly seen. However, some fractures and musculotendinous injuries may display subtle features and may be difficult to detect even with optimal images. We explain the mechanism of injury, discuss the diagnostic work-up and the operative and nonoperative management.

Abstract
PURPOSE Liposarcoma is the most common soft tissue sarcoma in adults. The purpose of the study was to correlate MR imaging features with the four ICD subclasses. METHODS 28 patients with liposarcoma were examined preoperatively on a 1.0 T MRI system, using spin echo sequences, gradient echo imaging and STIR sequences. In all patients, classification of the liposarcomas was made by histologic diagnosis (ICD-10-M-classification). RESULTS Well differentiated liposarcomas (9 patients) showed a number of MRI features consistent with lipoma (well defined mass high signal intensity (SI) on T1 images, low signal on T2 images, no or only little signal increase of tumour tissue after contrast material application, no necrosis). Not well differentiated liposarcomas (myxoid 14 patients, pleomorphic three patients, round cell two patients) revealed the largest part of the mass to be of low SI on T1-weighted images. Only scattered fatty islands and septa (9 patients with myxoid liposarcoma had more SI in T1-weighted images. T2-weighted image showed most of the mass to be of intermediate to high SI are the fatty island of relatively low SI. The probability of tumor necrosis increased with lower tumour grading. CONCLUSION MRI seems to be valuable to identify well differentiated liposarcomas.

Abstract
Multicentric reticulohistiocytosis (MR) is a rare systemic disease of unknown cause. The disease is characterized by tissue infiltration of lipid-laden histiocytes and multinucleated giant cells. Destructive polyarthritis and skin lesions are the most common findings. The disease becomes apparent in adult life. We report on 3 patients and discuss the specific radiographic characteristics of bone and joint involvement. The radiologic feature is a bilateral, symmetric joint involvement with predilection for the interphalangeal and metacarpophalangeal joints. In all of our cases we found an early involvement of shoulder joints. Erosive arthritis begins at the margins of the joints, progressing to osseous defects and to severe joint destruction. In contrast to rheumatoid arthritis, periarticular osteoporosis and early joint space loss are absent in MR. In addition, significant erosions of distal interphalangeal joints are not common in rheumatoid arthritis.

Abstract
AIM Identification of typical postoperative change after anterior cruciate ligament reconstruction (sutures, tendon grafts) and comparison with clinical tests and ultrasound. PATIENTS AND METHODS 50 patients with anterior cruciate ligament ruptures were examinated with MRI (1.0 T, surface coil, sagittal T1-3DFT-Fast and sagittal spin-echo), US and clinical function tests (Lachmann, pivot-shift, anterior drawer test). RESULTS In 19 of 21 patients with continuous low-intensity ligament structures in the MRI, knee stability was very good or good in the clinical tests and US. In 17 of 20 patients with a diagnosis of partial rupture at MRI, we also found a stable knee. 5 of 7 patients with the MRI-signs of ligament rupture showed knee stability at US and clinical tests. Furthermore, at MRI we found minor effusions in 10 patients, meniscus tears in 8 patients and ligament impingement in 2 patients. CONCLUSION MRI is a valuable method for evaluating and assessing anterior ligament reconstructions. We found a good correlation between the continuous low-intensity ligaments at MRI and knee-stability. In contrast there is a bad correlation between discontinuous ligament structures at MRI and clinical stability of the knee. MRI seems to provide more information than US and clinical tests (for example: minor effusion, meniscus tears, ligament impingement, bone lesions).

Abstract
Cytogenetic and flow cytometric studies in a variety of human solid tumors have suggested that gross aneuploidy may arise by a process of abrupt chromosome complement doubling followed by gradual chromosome loss. However, this sequence has not been demonstrated directly in serial studies in individual patients in vivo. The purpose of this study was to search for evidence of chromosome complement doubling and subsequent chromosome loss in flow cytometric ploidy patterns in serial bladder washings and/or biopsies from individual patients with early bladder cancer. Fifty-two patients with noninvasive bladder cancer were followed with serial flow cytometric DNA studies for periods ranging from 5.1 to 42.7 months (median 15.1 months). Serial changes in DNA ploidy and S phase fractions were recorded and correlated with histologic and/or cytologic findings, response to treatment and clinical outcome. The data suggest a series of genetic evolutionary changes in early bladder cancer that include the initial development of peridiploid aneuploidy and repeated rounds of DNA content doubling with chromosome loss in patients with progressive disease. It is likely that gross DNA aneuploidy, and more specifically, DNA multiploidy and DNA hypertetraploidy, all arise by this mechanism. The sequence of DNA diploidy, peridiploid aneuploidy, near-tetraploidy, hypotetraploidy and hypertetraploidy is associated with a progressive increase in S phase fraction, and with increasing tumor grade; late steps in this ploidy sequence were often present in tumors that were refractory to local therapeutic measures and tumors that developed deep tumor invasion and/or distant metastases. We conclude that DNA multiploidy and hypertetraploidy are markers of advanced stages of genetic evolution in human bladder cancer.

Abstract
We report on the radiological findings of 8 female patients with primary Sjögren's syndrome and pulmonary infiltrations. In the chest x-ray, all patients featured an interstitial diffuse bilateral reticular pattern which was most prominent in the bases. The apices of the upper lobes were not involved. There were no pleural effusions. The radiologic appearances changed only slowly. In three cases the lesions progressed to form a patchy confluent pattern. 4 of 8 patients developed within 24 months a nodal or extranodal lymphoma of low-grade malignancy.

We report about the radiologic diagnostic findings and the clinical manifestations of this defined pulmonary malformation. Radiologic findings are round or oval lobulated homogeneous masses. The size ranges from < 1 to several centimeters in diameter, most fistulas were located in the lower lobes. Feeding and draining vessels can be identified frequently on plain radiographs or tomograms/CT. Best procedure to recognize these malformations is the selective pulmonary arterial angiography.

Abstract
Although carcinosarcoma occurs in various locations throughout the body, it rarely originates in the ovary. Chemotherapy has been minimally beneficial. This case describes a patient with carcinosarcoma of the ovary who responded minimally to chemotherapy used for epithelial carcinomas but had a complete response after receiving chemotherapy used for sarcomas. The patient relapsed within 1 year after receiving cisplatin therapy. She was treated with mesna, ifosfamide, Adriamycin, and dacarbazine (MAID) chemotherapy and after one cycle of chemotherapy she had no evidence of tumor. She has received six cycles of chemotherapy without evidence of progression 13+ months since beginning MAID therapy. MAID chemotherapy may be useful in the treatment of carcinosarcoma of the ovary.

Abstract
Platelet-activating factor (PAF) receptor antagonists reportedly improve early postischemic neurological recovery and cerebral blood flow in selected experimental models. Their effects on posttraumatic cerebral edema have, however, not been examined. In a rat model of right hemispheric percussive cerebral trauma, we examined the effects of two PAF receptor antagonists on posttraumatic edema formation. Two groups of rats received either BN 52021 (n = 14) or WEB 2086 (n = 11), 10 mg/kg i.v. at 15 min posttrauma. Two other groups treated with the BN 52021 (n = 17) and WEB 2086 (n = 10) vehicles served as controls. Hemispheric percent brain water was determined at 24 h. Edema occurred in all groups. Neither PAF receptor antagonist significantly reduced right hemispheric percent brain water (81.08 +/- 0.25 and 81.04 +/- 0.15 in Bn 52021 and WEB 2086-treated rats, respectively, versus 81.31 +/- 0.23 and 81.14 +/- 0.17% brain water in BN 52021 vehicle and WEB 2086 vehicle-treated rats). Mortality was not statistically different between groups. These data do not support a major role for PAF in the development of posttraumatic cerebral edema.
