Lege Artis Medicinae - 2001;11(01)

[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 modern approach to the surgical treatment of osteoarthritis of the hip]

SZENDRŐI Miklós, SÓLYOM László

[The authors review the development of surgical treatment of osteoarthritis of the hip, including the joint preserving interventions for biomechanical reconstruction in prearthroses, and the joint deceasing, or joint replacing procedures in advanced osteoarthritis. Demonstrating the indications, contraindications and possible complications they point to the responsibility of the surgeon, and to the changes of the recent strategy comparing to the previous one. They give a „state of the art” description regarding the surgical treatment of osteoarthritis of the hip supported by references from the literature and their own experience.]

[Hip joint involvement in rheumatoid arthritis: pathological features and orthopaedic treatment]

LAKATOS Tamás, KORÁNYI Ágnes, GUNTHER Tibor, RÁCZ Dénes, UDVARHELYI Iván

[The authors review the orthopaedic surgical treatment possibilities of the hip joint affected by rheumatoid arthritis. In the first part, they draw the attention to the characteristic features of the disease. They describe a possible pathological interpretation of rheumatoid arthritis and emphasize the specific features of the rheumatoid hip joint. Different surgical interventions and treatment possibilities are analyzed. Because of the multiple joint involvement in these patients, the possibility of sequential operations has to be considered. The importance of close cooperation between rheumatologists and orthopaedic surgeons is emphasized. According to the authors, one of the most effective long term treatment possibility of the rheumatoid hip is the total hip arthroplasty.]

[Radiological diagnostics in bone metastases]

GŐDÉNY Mária, BODOKY György

[Imaging plays a crucial role in defining bone metastases, and thus, therapy planning. We are responsible for accurate data collection, pre-treatment evaluation, evaluation of therapy response and post-treatment evaluation. Precision highly depends on the expertise and experience of the evaluating radiologist, and therefore, being familiar with the latest literature is essential. The bone status can be detected well by bone scan, analysed by conventional X-ray examination and by the cross sectional digital imaging modalities. The whole body PET/CT functional imaging is becoming increasingly popular in the metastatic workup of patients and for monitoring response to therapy. MRI has been found to be the most accurate method for bone metastasis in most comparative evaluations in the literature. This article is a review of the latest papers focusing on the clinical significance of the imaging results in bone metastasis diagnostics.]

[DIAGNOSTIC POSSIBILITIES IN HEAD AND NECK MRI]

GŐDÉNY Mária

[Digital cross-sectional imaging techniques, especially computed tomography (CT) and magnetic resonance imaging (MRI) play an important role in the diagnosis of pathologic conditions affecting the head and neck. MRI, because of its superb soft tissue contrast resolution and multiplanar imaging ability gives the most information regarding the origin and the extent of a laesion, intracranial extension, perineural-, as well as bone marrow involvement and play key role in the management of different diseases. Careful observation of the characteristic radiological features usually leads to correct diagnosis, however, some of the lesions are not typical, looking very similar and can be difficult to differentiate from each other. The purpose of the present article is to provide an overview of the most common pathologic conditions examined with MRI.]

[Prenatal diagnosis of central nervous system malformations]

LANGMÁR Zoltán, NÉMETH Miklós, CSABA Ákos, SZIGETI Zsanett, JOÓ József Gábor

[The prenatal diagnosis of fetal malformations have been the subject of numerous publications in the literature. This has dramatically increased in the last 15 years, mainly due to the advent of high-resolution ultrasound. In addition adequate guidelines issued by professional organizations have encouraged the universal approach to the imaging of fetal anatomy as well as malformations. One of the most significant groups of the fetal anomalies is the central nervous system malformation. Due to its prevalence and severity the praenatal diagnostics of central nervous system malformations got basic significance. In this review we attempted to summarize the recent informations concerning the praenatal diagnostics of the central nervous system anomalies.]

[Ethiopathogenesis of polycystic ovarian syndrome and imaging diagnostics of polycystic ovary]

JAKAB Attila, MOLNÁR Zsuzsanna, TÓTH Zoltán

[Polycystic ovarian syndrome is a heterogenous syndrome with a wide variety of endocrine and metabolic abnormalities and clinical symptoms. It is considered as the most frequent endocrine disorder in women in reproductive age and the most common cause of anovulatory infertility. Key features include menstrual cycle disturbance, hyperandrogenism and obesity. There are many extraovarian aspects to the pathophysiology of polycystic ovarian syndrome, but ovarian dysfunction is central. The underlying unique feature of the ovarian morphology gives the significance of the ultrasound examination. At a recent consensus meeting, a refined definition of the polycystic ovarian syndrome was agreed, encompassing a description of the morphology of the polycystic ovary. The subjective appearance of polycystic ovary should not be substituted for the definition. Further, a woman having polycystic ovary in the absence of menstrual disorder or hyperandrogenism (asymptomatic polycystic ovary) should not be considered as having polycystic ovarian syndrome, until more is known about the situation. Since ultrasound description of polycystic ovary morphology has central role in the diagnosis, and untreated polycystic ovarian syndrome carries long term health risks, the increasing attention to ovarian morphology may offer an effective tool to decrease women`s morbidity. This review outlines the background and feature of ovarian morphology in polycystic ovarian syndrome, and details the current ultrasound definition of polycystic ovary.]

[Frequency and diagnosis of pediatric air gun injuries]

MAKRA József, LOMBAY Béla, RIVASZ-TÓTH Gyula

[INTRODUCTION - Air guns are frequently given to children as toys. Air guns have a pellet caliber of 0.17 or 0.22 and are propelled by compressed gas. Though they have little penetrating effect, they may cause life threatening injuries. Our purpose was to evaluate the frequency and the development of the diagnostic opportunities in children with air gun injuries during the last 30 years (1971-2000). PATIENTS AND METHODS - 52 patients (39 boys and 13 girls) were admitted to our pediatric surgery department due to of air gun injuries. The average age was 9 years (range 2 to 14 years). During the first fourteen years conventional X-ray (plain film and fluoroscopy), since 1984 ultrasonography and later (1986) CT has also been used for the diagnosis. RESULTS - In the first ten years 12 patients, in the second decade 18 patients and in the third ten years 22 patients were admitted and treated with air gun injuries. The sites of injury included upper, lower extremities (n=23), head (n=10), neck (n=5), chest (n=9) and the abdomen (n=5). The majority of patients had superficial injury and Xray plain films in different views were obtained, only. Major complication occured in 10 cases: bone fracture (n=1), soft tissue abscess (n=4) pneumothorax and hemothorax (n=4), bowel perforation (n=1). In these cases ultrasonography and/or CT was performed and they were helpful to establish the correct diagnosis. CONCLUSION - The general conception that air guns are toys, is basically wrong. The practice of placing air guns in the hands of children by their parents is very dangerous. On the basis of our results, the frequency of air gun injuries in children increased significantly in the last decade and the injuries were more serious than before (due to thew technologic modification of air gun). Ultrasonography and CT have important role in the diagnosis, but conventional X-ray remains the basic method in most of cases.]
