[Mammography and echography in the diagnosis of expansive lesions in the dysplastic breast].

The authors evaluated 177 cases of expansive lesions observed in diffusely dysplasic breast. The size of the lesions was less or equal to cm 2. They found that mammography had its diagnostic difficulties in benign lesions such as fibroadenomas and fibrocystic disease. Ultrasonography was carried out on 106 of those patients. The sensitivity of ultrasonography was the same for the definition of benign and malignant lesions. Moreover, it was not modified by the diffuse dysplasia.

[The biphasic contrast method in the stomach examination. A comparative study with standard method and correlations with endoscopy (author's transl)].

A two years-experience, using the biphasic contrast method in the evaluation of the stomach, is reported. Endoscopic and radiological results are compared. Our previous reports with standard contrast method are also reviewed. Ulcerative and neoplastic pathologies were studied and classified as proposed in the "trial policentrico multidisciplinare paritetico". The double contrast method has greatly increased the accuracy of X-ray diagnosis, considerably reducing the difference with endoscopy.

[Results of a study of the resected stomach using biphasic and traditional technics].

The authors report their results in the evaluation of 181 gastroresected patients. All these cases were clinically selected; 96 of them have been examined by using standard biphasic-contrast examination and 85 by using traditional radiological technique. Their aim was to determine the contributions of the new technique in the evaluation of the resected stomach and to effect a critical review of the traditional one. Their results show that the standard biphasic-contrast examination carries out a notable improvement in the radiological diagnostic accuracy. It reduces greatly the discrepancy between radiology and endoscopy.

[Multi-institution, multidisciplinary radiology and endoscopy trial of the diagnostic accuracy of the double contrast examination of the stomach surface].

In 12 X-ray and gastroenterology departments 1570 patients, clinically suspected to have a gastric pathology, have been examined by double contrast (surface) examination of the stomach followed by gastroscopy. Diagnostic accuracy was 93% in respect of endoscopic data, assumed correct by hypothesis. On the basis of a cost and benefit evaluation, made according to the well known criteria, a wider routine use of the double contrast technique is proposed.

[Criteria for choosing the screen-film system in x-ray diagnosis (author's transl)].

The physical dimensions to be kept in mind in choosing the screen-film system in radiography are defined and discussed. As an example of applying the method, the results of measuring these dimensions on 5 types of film and 6 types of screen are reported and their optimal combinations indicated as a function of examination conditions.

[A protocol for evaluating screen-film systems].

When a competition is made for the supply of sensitive photographic material, each USL is asked, in a time scan of one or more years, to evaluate the characteristics of the screen-film systems proposed by the various companies. In the last years the authors had several opportunities to check different screen-film systems for many Friuli-Venezia Giulia hospitals. For this reason they have set an evaluation form tested after following changes and recently employed in its final version. The check form is reported on in this paper with some personal considerations originated by the authors' experience. The technical parameters which must be evaluated are reported, together with the instrumentation needed to perform the technical examination, the examination modality, and the score-attributing criteria. The evaluation form is very flexible for it allows each Radiology Department to evaluate each parameter in a personal way and to fit it to its own needs.

[Ultrasonic-guided fine-needle biopsy of osteolytic lesions].

Percutaneous biopsy of lytic lesions of the bone, in the past pertaining to orthopedic surgeons, has now become a part of interventional radiology. Fluoroscopic guidance has simplified its execution. US does not, under normal conditions, allow an accurate examination of the skeleton; on the other hand, when the bone tissue is replaced by soft tissue, US can easily demonstrate the presence of a tumefaction, caused by a lytic lesion, and determine its characteristics. Eleven patients with lytic lesions (recognized on plain film) underwent US. The lesions were demonstrated. In such cases, biopsy is essential to define their benign or malignant nature, in the latter case if primitive or metastatic, and their histology as well. US is a simple guide to the biopsy of noncorticalized lytic lesions, and it offers consistent advantages over fluoroscopic guidance--i.e. it is easier to perform, it requires no X-ray exposure, it provides with three-dimensional images, the guide is performed in real time, and a choice of the most appropriate (non-necrotic) areas is possible.

[Findings in myelographic block. Correlations with computerized tomography image].

Fifteen cases with complete myelographic stop were examined by CT. CT showed stenosis of the spinal canal in 11/12 cases with extradural lesion (92%). The stenosis was or was not associated to disk pathology; one case was due to a large herniated disk. Three cases were due to a neurinoma and were not visualized at CT without intrathecal contrast medium. This situation represents a limitation of CT and therefore an indication for myelography.
