Results

We have made a plug-in for a free widespread DICOM viewer software based on a personal computer configured in server function.

Images of 50 metastatic patients are been taken from the PACS system using a local high speed network connection, and hepatic findings are been used for scientific purposes.

All focal liver lesions were studied both at conventional CT workstation, by an expert radiologist, and by the software automatic evaluation.

We analyzed CT images of 50 patients with liver metastases and for each patient was analyzed up to a maximum of three lesions.

For each lesion was considered the dimensional and the densitometric criteria and were obtained 3D reconstructions.

Results was compared by an other expert radiologist that saw all the images and the software reports.
