Analogic versus digital mammographic examination a radiological study of mammary microcalcifications on 52 surgical samples.

Purpose: Digital mammography is known to have lower spatial resolution compared to conventional analogic mammography. The aim of this study was to evaluate whether this physical feature could compromise the perception of microcalcifications in radiological findings.

Materials And Methods: Fifty-two surgical samples of non-palpable breast lesions with microcalcifications were imaged using both techniques.

Tubal catheterization and selective salpingography.

Hysterosalpingography with selective salpingography is by now a well-established technique in the diagnosis and therapy of some forms of female sterility especially in relation to tubal disease. The experience with a group of 302 patients with unilateral (187) or bilateral (115) proximal tubal disease, is reported. As for the catheterization of obstructed tubes, the technique was successful in about 94% of cases, while failure was observed in 6% of cases due to organic disease which hindered the transit of the angiographic guidewire or catheter.

Dynamic contrast-enhanced ultrasound with carbon dioxide microbubbles as adjunct to arteriography of liver tumors.

Purpose: The goal of the study is to evaluate utility of contrast-enhanced ultrasound (US) with carbon dioxide microbubbles in evaluation of hepatic lesions.

Methods: Twenty-eight patients with single or multiple hepatic lesions (11 hepatocellular carcinoma, 8 hemangiomas, 5 metastases, 1 adenoma, 1 focal nodular hyperplasia, 2 regenerative nodules) were examined. US exam was performed during intraarterial injection of 10 ml of CO2 through the same catheter employed for liver arteriography.

[Percutaneous transjugular intrahepatic portosystemic shunt (TIPS). The preliminary experience and proposal of a new method].

A new interventional procedure employing metallic stents has been recently suggested to perform percutaneous portosystemic shunts in the treatment of variceal bleeding in portal hypertension; the technique is called TIPSS (transjugular intrahepatic portosystemic stent shunt). This percutaneous treatment presents several advantages over surgery: the shunt diameter can be calibrated according to the degree of portal hypertension; moreover, TIPSS can be performed in patients waiting for liver transplantation because it does not alter the vascular anatomy of liver. The original technique employed transhepatic portography.
