Artificial intelligence and radiomics enhance the positive predictive value of digital chest tomosynthesis for lung cancer detection within SOS clinical trial.

Objective: To enhance the positive predictive value (PPV) of chest digital tomosynthesis (DTS) in the lung cancer detection with the analysis of radiomics features.

Method: The investigation was carried out within the SOS clinical trial (NCT03645018) for lung cancer screening with DTS. Lung nodules were identified by visual analysis and then classified using the diameter and the radiological aspect of the nodule following lung-RADS.

[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.

[Percutaneous needle biopsy of the lung. Critical review of 496 cases].

Between February 1979 and December 1986, 618 lung biopsies were performed on 496 patients (122 with double puncture, using Tru-cut and 19-20 G needles). Overall diagnostic accuracy was 84.5%; the 77 patients examined in the past 18 months only underwent thin needle (19-20 G) biopsies--which were carried out by an experienced radiologist--and more sophisticated cyto-histological techniques were employed.
