[Special radiology of the hand in renal osteopathy].

The different radiographical abnormalities of the hand with renal osteodystrophy are demonstrated. The soft tissue immersion low-energy X-ray technique allows early detection of macrostructural changes of spongy and compact bone, irregularities of the cortex, defects and pseudocysts, osteosclerosis as well as calcifications in the soft tissue and arterio sclerosis of patients with chronic renal failure. Possible erroneous interpretations will be discussed.

[Common roentgen morphology of generalized osteopathies].

The generalized macromorphological x-ray findings of the different kinds of osteopathy are discussed. These metabolic bone diseases include osteoporosis, osteomalacia, secondary hyperparathyroidism caused by renal osteopathy and all possible combinations. The complications caused by hormonal and metabolic bone disease are described. The pathomorphological significance and value of follow-up studies with regard to therapeutic procedures are explained.

[Detection of occult fractures of the pelvic bones by roentgen computed tomography].

The informational value of C.T. concerning pelvic fractures is presented. Not all injuries to the hip joint and to the os sacrum can be seen on standard a.p.-projections, oblique views, special projections or conventional tomography. 17 typical examples have been selected from young patients with multiple injuries. C.T.-findings concerning fractures of the hip joint, of the os sacrum and of hidden pelvic fractures are described. Emphasis is placed on careful radiological analysis of fractures with special regard to the planning of conservative or operative treatment and also on the later functional results following fractures of the hip joint.

[Information value of x-ray computed tomography for the detection and control of spondylitis].

The information content of early bone changes in computed tomography (CT) of pyogenic non-tuberculous spondylitis and spinal tuberculosis is analysed. The CT findings are compared with conventional x-ray images including tomography. In 3 of 16 patients no indications of osteomyelitis were found by conventional x-ray images, whereas CT revealed paravertebral soft tissue swelling or abscesses and osteolysis and thus established the diagnosis of spondylitis. In one patient the process caused neurologic symptoms by extending into the epidural space. The contributions of CT to the diagnosis of spondylitis are to delineate the extent of soft tissue swelling, to detect small defects in the vertebral bodies, to exclude disc involvement, and to differentiate inflammations and other destructive changes. CT can be used for fine needle localization and aspiration of tissue or pus for histological or bacteriological investigations to establish the pathological diagnosis.

[Informational value of weak-radiation immersion radiography of the hand in hormonal and metabolic osteopathies].

The early detection of changes in the bones of the hand in hormonal and metabolic osteopathies is possible with the aid of soft tissue immersion radiographic technique combined with "microradioscopy". The informational value of this special method of investigation will be demonstrated by several examples from the 286 examinations of accentuated osteoporotic and osteomalacic and hyperparathyroidism changes of the skeleton. Structural changes in the normally mineralized and poorly mineralized bone as well as the neighbouring soft tissue (joint capsule, tendons, subdermal fatty tissue) and the skin layer itself can be demonstrated. Examinations following therapy in the hospital or in private practice using this painless special method can demonstrate changes of the macrostructure and during the process of healing within the bone.

[Course of Paget's osteodystrophia deformans--exemplified by the roentgen morphology of the cranial bones].

The still unknown etiology and pathogenesis of Paget's disease or Osteodystrophia deformans Paget are discussed; localisation of skeletal lesions and clinical findings of the disease are described. The skull bones are used to give an example for the 4 phases of the course of the disease, shown by X-ray pictures. Typical X-ray findings of changes in structure, pattern, size, and shape of the skull bones are compared with the pathological and anatomical picture.

[Rare localization of Paget's osteodystrophia deformans in the skeleton].

Frequency of rare skeletal lesions in Paget's disease is compared with normal localisations. Radiological morphology of rare localisations of Paget's disease of the scapula, of the lower arm bones, of the hand bones, of the patella and the calcaneus are described. Thickening of trabeculae in the spongy bone and porosity of compact bone, deformation and enlargement of the bones are typical; this has to be differentiated and related to a small number of other bone diseases.

[The information value of roentgen computerized tomography in atrial tumors of the heart].

The symptoms of intracavitary masses are usually not characteristic and are often confused with those of mitral valve disease. It is therefore necessary to employ all possible diagnostic measures. Like echo cardiography, computer tomography is a non-invasive method which provides accurate information concerning the size, position and shape of the mass. Angiocardiography can confirm these findings, but provides extra information only if there are additional abnormalities or coronary disease. Early diagnosis is important, since the patient is at risk from complications such as cardiac failure, emboli and arrhythmias, and since operative removal of the tumour carries a good prognosis.

[Diagnostic possibilities of computed x-ray tomography in thorotrast accumulation].

Quantification of Thorotrastosis is easily obtained by means of computerized tomography. Th-concentration, total Th-content in an organ and the percentage of contaminated parenchyms can be evaluated. Some examples of such measurements are presented. Conventional x-ray morphology and CT-findings are demonstrated by hand of several cases of thorotrast tumors and other patients with Th-induced lesions.

[Roentgen morphology of sport injuries to the pelvic apophyses].

Pelvic apophyses are places of insertion of strong muscles and tendons and are therefore places of least resistance at the end of skeletal growth. Avulsions and disruptions of pelvic apophyses can be caused by overstrain during different kinds of sport activity. Typical radiological findings in 8 different cases of ruptures of apophyses, osteochondropathies, and resulting conditions of sport injuries are demonstrated. The difficulties of correct diagnosis and differential diagnosis are pointed out. The significance of hormonal impairment of ossification for development and stress factor of pelvic apophyses is exposed. Questions of treatment and follow-up studies are discussed.

[Normal renal variations as a cause of sonographically suspect tumors].

106 cases of 470 computed tomographic studies of suspected renal tumors were referred to us because a tumor was expected by ultrasound examination. 67 suspected renal tumors proved to be physiological variations, in 39 cases tumor suspicion was confirmed by computed tomography. Since ultrasound findings frequently seem to be false positive, criteria for the diagnosis of renal tumors were reviewed. Our experience is that the combination of inhomogeneity in echo pattern, irregularity of the outer contour and/or the inner parenchymal border seems to be relevant for ultrasound diagnosis of renal tumors whereas isolated widening of parenchyma does not seem to be suspicious by itself.

[An unusual form of osteoarthropathy in psoriatric erythroderma].

Follow-up study is reported of an unusual osteoarthropathy showing considerable changes in the vertebral column and connected with a psoriatric erythrodermia. X-ray findings are growing metaplastic ossifications in the capsular ligaments, which are extremely prominent in the regions of shoulder joints and hip joints. In the vertebral column cervical and lumbal regions are especially attacked and in fibro-ostitis huge metaplastic ossifications of the ligaments develop, which radiologically are very similar to the picture of an ankylopoietic spondylosis. After long-term therapy with high doses of cortisone the patient developed diabetes mellitus and Cushing-syndrome. The arising complications soon caused her death.

Computed tomography of the adrenal glands.

Whole body CT opens a third dimension-in addition with the advantage of being a non-invasive method with relatively negligible risk. Both, the normal CT findings of the adrenal gland and the normal variants in shape and position are described. With help of morphometry and image processing measurements of the size of the adrenal gland of 20 healthy patients were made and are listed; not only the respective normal variants but also hypo-hyperplasia are pointed out. Some examples are suitable for the illustration of pathologic conditions, such as inflammation and benign and malignant primary and secondary neoplasis. Finally, the value of adrenal gland CT is discussed with reference to the other radiologic methods.

[Problems in radiology of concealed lung disorders (author's transl)].

The problems of diagnostic radiology in dealing with discreet and difficult to find pathological lung conditions are demonstrated by typical examples. Special emphasis is given to localized changes found in paramediastinal and paracardial regions of the lung and the diaphragm. Special attention was given to patients with elusive or hidden lung disorders and the value of information by X-rays of more than one dimension, by spot films taken during fluoroscopy, by bronchography, by tomography, and by computed tomography is discussed. Early diagnosis of lung and bronchial carcinoma as well as infections of the lung parenchyma can only be found, if the radiological methods are optimally used.
