[Role of computerized tomography in percutaneous drainage of acute infected necrotic-hemorrhagic pancreatitis].

In the last few years, Computed Tomography (CT) has emerged as the most sensitive and reliable imaging technique to diagnose acute pancreatitis (AP). Besides assessing the extent of damage to the pancreas and to periglandular tissue. CT can recognize the major early and late complications of the disease promptly and with extreme accuracy.

[The role of portography with computed tomography in the diagnosis of liver metastases from colorectal neoplasms].

This study was performed to confirm the high sensitivity of CT during arterial portography (CTAP) versus US and dynamic CT in the diagnosis of liver metastases from colorectal cancer. Ninety patients with 108 colorectal cancers underwent US, dynamic CT and CTAP to investigate the presence of liver metastases. US depicted 39 metastases in 26 patients, dynamic CT 46 metastases in 29 patients and CTAP 54 lesions in 34 patients.

[Cholecystography and ultrasound compared in the radiological diagnosis of chronic cholecystitis].

In 50 patients awaiting cholecystectomy, both cholecystography and cholecystosonography have been performed (or repeated), in order to examine the gallbladder wall implementing both examinations with the cholecystokinetic test. The results, related to the surgical, anatomical- and histo-pathological reports, show that, to detect gallbladder parietal lesions, the two studies are complementary in the diagnosis of cholecystitis: consequently, in the authors' opinion, they should always be carried out in association, with the exception of cases when cholecystography may not be possible either because of radiation protection reasons or because of jaundice. Although further experiments are required, it is suggested that the cholecystokinetic test be revalued.
