This is a case report of 3 cases from the same family with multiple epiphyseal dysplasia. The disease is an uncommon congenital dominant hereditary disease of the bone characterized by multiple and symmetrical skeletal involvement with retardation of epiphyseal development, accompanied by irregularity and shortening of toes and fingers and yet still maintaining the normal proportion between the trunk and extremities. The intelligence is not affected. In the adult patients, sloping of distal tibial articular surface associated with degenerative changes of both hip joints is a reliable diagnostic sign. The aforementioned X-ray signs are helpful to distinguish this condition from other chondrodysplasia diseases.

This paper reported the preliminary experience of direct sagittal CT of temporomandibular joint (TMJ) and its modalities of TMJ was made. By using a specially devised table, the bony structure and disc of TMJ can be well demonstrated. The major advantage of this technique is direct demonstration of the articular disc and a diagnosis of anteriorly displaced meniscus which is reducible or irreducible can thus be made. The application of CT in internal derangement of TMJ will open up new insight into the diagnosis and management of these patients.

11 cases of idiopathic unilateral hyperlucent lung were reported: The clinical pictures and X-ray findings were analysed. The main X-ray changes were abnormal hyperlucency of the affected lung or lobe while the size of the hyperlucent lung was normal or smaller than the contralateral side. The hilar shadow and vascular markings fine and decreased During respiration, the volume of the affected lung remained constant but the mediastinum shifted to the affected side on inspiration and away from it on expiration. The affected lung retained its radiolucency on expiration. The broncho-pulmonary angiogram, lung CT scan and pulmonary vascular tomograph were studied. The clinical pictures, etiology, pathology, X-ray diagnosis and differential diagnosis were discussed.

68 cases with 76 left ventriculographies, including rheumatic mitral valvular disease, congestive and hypertrophic types of cardiomyopathy, endocardial cushion defect, atrial and ventricular septal defects, coronary heart disease and mitral valve prolapse were analyzed with respect to the morphological and functional changes of the mitral valve and its appendages. Dynamic study with cineradiographic technic was the chief method used in this investigation. Except for ventricular septal defect, all the above-mentioned disease entities showed one or several of the changes of the mitral valvular apparatus including stenosis, insufficiency, displacement, cleft, deformity, prolapse and functional disorder. Regurgitation associated with mitral insufficiency exhibiting specific manifestations in different conditions was analyzed and its method of grading discussed. Mitral valve prolapse with its suggested method grading and functional disorder of the mitral valve were also discussed in detail.

CT findings of 17 patients with neuron migration anomalies, 5 with lissencephaly, 6 with schizencephaly and 6 with heterotopic gray matter were reviewed. Migratory anomalies are congenital malformations caused by insult to the neurons during the time of migration. CT is effective in detecting these malformations.

This article reported the result of the chest radiographs of 14 patients with trichinosis, in regard to the X-ray manifestations, pathologic basis and clinical significance. The radiologic findings included hilar enlargement, exaggerated and fuzzy lung markings, and pulmonary patchy infiltrations of varying sizes as well as fine nodular shadows. The pathologic basis consisted of dilatation and congestion of pulmonary vessels and capillary beds and intrapulmonary hemorrhagic lesions. The pulmonary radiologic manifestations are helpful for estimating patient's prognosis.

This paper reported the result of clinicoradiologic analysis of 37 patients with diabetic osteopathy. The site of predilection was the bony ends of the extremities, especially the foot (91.9%). The main clinical manifestation was the presence of a non-healing chronic ulcer, whereas diabetic gangrene of bone constituted the chief x-ray finding, which was characterized by osteolytic destruction at the bony ends of metatarsals and phalanges, with minimal periosteous reaction if any. The bony articular surfaces were usually preserved. The chief distinction to be made is osteomyelitis. The mechanism of diabetic osteopathy is most probably systemic metabolic disorders resulted from disturbance of carbohydrate metabolism with secondary neurovascular changes. Infection probably plays the role of enhancing effect in gangrene of bone.

38 patients with functional microadenoma were investigated with high-resolution computed tomography and only coronal scan was done. All patients were documented with surgery and pathology. On coronal CT scan, the density, height and the shape of the pituitary gland, as well as the bony structure of the sellar floor could be displayed clearly. Our results indicated that these four criteria were reliable in the diagnosis of microadenoma. If coronal CT demonstrates a normal pituitary gland, in our opinion, it is not necessary to take other X-ray examinations.
