[Radiologic types in mammography in the 90-s. New classification].

The Authors present a critical review of the classification of radiological types in mammography proposed in 1986. On the basis of their personal experience over the past years, and in the light of the changed indications given by screening the asymptomatic population, a series of 6,072 mammographies performed over a 12-month period were included in the study. These were non-selected cases undergoing X-ray examination for a variety of reasons, ranging from periodical control to carcinophobia.

[What is the real value of mammographic screening of an asymptomatic population?].

The Authors present a critical review of over 14,000 mammographic exams, and they compare this series with previous series. The results demonstrate that, even if there is an increase in the number of women subjected to mammography, there is no significant increase in tumor incidence.

[Percutaneous localization of breast lesions. Personal experience].

A critical analysis is made of a series of percutaneous localisations of radiological breast lesions. The Authors underline the importance of close collaboration between the various specialists in order to obtain an early diagnosis which, in breast cancer, ensures a better prognosis and also avoids the necessity of radical surgery which affects the woman's attitude towards cancer.

[Mammographic screening of a random population. Evaluation of 16,500 cases].

After analysing data collected over a 5-year period, the Authors emphasise that screening for breast cancer is becoming increasingly common-place. This has led to a marked improvement of the prognosis of this pathology.

[Pneumocystomammography].

The Authors re-examined a series of 50 female patients after 12 months to assess the diagnostic and therapeutic value of percutaneous evacuation of mammary cysts, followed by a radiological study using PNCMX.

[Diagnostic value of calcifications in mammography].

The authors underline the importance of the mammographic screening of calcifications in the early diagnosis of breast tumours. Most of the time, their semeiology seems to be well codified in benign and malignant lesions, although the "visibility threshold" is still not very satisfactory, even by the valuable xeromammographic method.

Thermographic findings in cranio-facial pain.

This work assesses the differences in the thermographic findings in the craniofacial and neck areas between normal individuals and patients with craniofacial pain or headache, and investigates the influence of muscle contraction on such findings. Thermographic records were taken in 10 healthy subjects and 47 patients suffering from craniofacial pain or headache of different kinds. In the patients with painful episodes the record was taken between attacks.

Variations of skin temperature in patients with craniofacial pain. A thermographic evaluation.

Thermography of craniofacial region was taken in 33 patients with different types of craniofacial pain. In 26 patients (78%) a thermal asymmetry was found which corresponded to the painful area in 19 patients (57%). It can be concluded that temperature alterations in different areas of the face are common in such patients and are probably the consequence of functional alterations of the sympathetic system.

[Percutaneous biopsy (PB) of solid thoraco-abdominal formations with instrumental guidance. The authors' experience].

The results are reported of 283 percutaneous biopsies performed on solid thoracic and abdominal masses. Indications to biopsy are examined at first, which are relatively limited in number if compared to other authors' opinion on the subject--i.e.

[Mammography in screening in breast studies. Retrospective analysis of a personal series].

The authors point out the value of mammography in the screening as the examination of choice, based on a personal series of more than 12,000 patients examined between 1980 and 1986, and distributed according to a personal classification.

[Tomodensitometric evaluation of retroperitoneal damage caused by translumbar aortography].

23 patients were scanned over the abdomen following translumbar aortography. Retroperitoneal bleeding was smaller than expected and never serious for the patients. The use of computed tomography is considered helpful in the follow-up of patients after translumbar aortography; however it must be restricted only to patients with a previous difficult or traumatic procedure.

[Sequential endovenous angiourography (AUS) with image subtraction for the study of the arterial phase of urography. Comparison with nephroangiotomography (NAT)].

Two urographical techniques employed in the endovenous study of renal arteries are compared. They are nephroangiotomography (NAT) using synchroplan and sequential angiourography (SAV) with image subtraction. 64 patients were studied, 32 with NAT and 32 with AVS.

[Instrumental follow-up of patients treated by internal biliary drainage].

The various radiological techniques available for the long-term follow-up of patients given definitive percutaneous trans-hepatic biliary implants (DTBI) are evaluated on the basis of personal experience. After a rapid examination of the available technics it is concluded that direct X-ray, echotomography and sequential hepatobiliary scintigraphy are more than sufficient for an accurate follow-up of the disease in such patients.

[Proposal of an echotomographic method of guided portal catheterization].

To identify the frontal plane on which to find the right branch of the portal vein in 33 patients who underwent transhepatic percutaneous portography, we used a real-time ultrasonic scanner improved with an original device conceived for this specific need. The suggested method reduced the number of the ineffectual punctures of the liver, allowing in nearly all cases the cannulation of the right branch on the first attempts.
