Chest radiography with a shaped filter at 140 kVp: its diagnostic accuracy compared with that of standard radiographs.
The effectiveness of a shaped filter in the detection of mediastinal and retrocardiac abnormalities on 140-kVp posteroanterior chest radiographs was measured by observer-performance testing. A set of 100 radiographs (the filtered and nonfiltered radiographs of 50 patients) were randomly selected from 1000 radiographs obtained from 500 outpatients or hospitalized patients. Five observers independently interpreted the set of radiographs, with one observer interpreting the set twice. Observer performance in detecting abnormalities in the mediastinum and the retrocardiac lung were analyzed by using receiver-operating characteristic techniques. The results indicate that the use of a filter has no significant overall diagnostic advantage (areas under the receiver-operating characteristic curves were 0.90 for the filtered radiographs and 0.89 for the unfiltered radiographs). No significant differences were found in the analysis of the various types or locations of lesions in the mediastinum.

[Lumbar intradural disk herniation. X-ray computed tomographic diagnosis].
Intradural disk herniation is a rare condition. Most of reported cases involve the lumbar spine and have histories of chronic low back pain followed by an acute episode of radicular pain with neurologic deficit. The authors report the myelographic and lopamidol-CT findings in a case of a L4-5 intradural disk herniation. These two examinations demonstrated an intradural multilobular mass associated with an extradural component at the level of the disk space and with a same density as it. Anatomic adherences between dura-mater and posterior longitudinal ligament could explain the primary mechanism of these intradural disk herniations; but operative or traumatic antecedents are often noted. Most often operation discloses only the intradural component with a small anterior dural cleft, without extradural abnormalities. Postoperative follow up is usually good.

[Spontaneous fracture of the sacrum due to "insufficiency". An overlooked cause of low lumbago in elderly women].
A case of insufficiency fracture of the sacrum is reported. These fractures usually occur in elderly women and are secondary to various conditions, mainly postmenopausal or steroid-induced osteoporosis and radiation therapy. They are often overlooked or confused clinically and radiographically with metastatic disease. Findings on plain films are often subtle. Radionuclide bone scan shows a characteristic H or butterfly shaped pattern of increased uptake in the sacral alae. The diagnosis is confirmed by conventional tomograms or CT which show the fracture always surrounded by prominent sclerosis.

[Bone metastases of bronchial carcinomas. 3 cases of subperiosteal cortical osteolysis].
The morphologic appearance of osseous metastasis may rarely suggest a specific site of origin. A subperiosteal location has recently been reported to be typical for metastatic lung carcinoma. We report three cases of such metastasis which destroyed the cortex so that it appears saucer shaped. The primary tumor was a bronchogenic carcinoma in every case. We conclude that in the cancer-age group cortical metastasis is a highly characteristic feature of lung carcinoma.

[Modified profiles of the elbow in traumatology. The value of the radial head-capitellum view and a new coronoid-trochlea view].
2 modified lateral views of the elbow are described. They are accomplished by angling the tube 45 degrees cranially and ventrally, parallel to the arm. The first view, recently reported, shows the radial head and capitellum, free of overlap of other bones. The second view, first reported here, demonstrates well the coronoid and the trochlea. Some representative case reports are exposed. The usefulness of these view is discussed.

[Magnetic resonance imaging in the exploration of hepatic masses].
Exploration was conducted by magnetic resonance imaging (MRI) at 0.15 T in 33 patients with hepatic masses, including 18 with malignant tumors, 11 with benign tumors and 4 with non-tumoral masses. All tumors appeared hyperintensive in relation to liver on images acquired by long TR spin echos (SE) and all, except for one fatty tumor, appeared hypointense in relation to liver on images acquired in inversion-recuperation (IR). The study seemed to provide data demonstrating that MRI at 0.15 T enables visualization of hepatic masses with a degree of precision that approaches that of other imaging methods. Tumors of the small size of the order of a centimetre can be detected. Tumor outlines and vascular relations are clearly demonstrated without use of contrast. Characterization of masses is still insufficient since the simple play of contrasts between tumor, parenchyma and vessels does not allow differentiation of malignant from benign tumors, nor the identification of a given histologic type.

[Tomodensitometric aspects of a case of intracranial toxoplasmosis in an immunosuppressed patient].
The case of a 42 years old man who had a monoblastic acute leukemia treated by a bone-marrow graft is described. The patient died of a cerebral toxoplasmosis and a cerebral computed tomography done two days before is correlated with anatomopathologic slices done in the same planes than the computed tomagraphy examination. There is a good correlation between necrotic abceded areas and hypodense areas accompanied by serpiginous fixations of contrast media. The immunocompromised patient is very favorable for the development of a cerebral toxoplasmosis. CT, while not specific, has the advantage to suspect the diagnosis which must be discussed with other oportunistic infections, leukemic infiltrates, methotrexate encephalopathy, progressive multifocal encephalopathy, and small infarcts.

[Intramural hematoma of the esophagus after endoscopic sclerotherapy. X-ray computed tomographic aspect and course].
A case of intramural oesophageal hematoma following endoscopic sclerotherapy is reported. CT showed a spontaneous hyperdense masse without enhancement after intravenous bolus of contrast material which confirmed the diagnosis; it permitted to eliminate another abnormality (e.g. perforation) and to survey the evolution (complete recovery without treatment in about four weeks).

[Pectineofoveal spur of the femoral neck. A rare variant from the normal].
A small bony spur on the infero-internal surface of the femoral neck was observed in radiographic images of two adult subjects in whom clinical signs of hip disorders were absent. This is though to be a variant of the normal not previously described; the spur probably results from ossification of the pectineofoveal capsular fold at the level of its femoral insertion.

[Intraspinal calcifications. Symptomatology. Pathologic value].
Calcifications in the spinal canal on plain films are not an unusual finding. The authors present 22 such cases. Identification and pathological value depend on the topography and morphology of these calcifications. The calcifications have been classified in three groups: anterior, median and posterior. The most common etiologies for the anterior ones were calcifications of the posterior longitudinal ligament and calcified discal hernias; meningiomas were the most common cause of the median calcifications; ligamentum flavum calcifications accounted for must of the posterior ones.
