Atypical Enhancement of Gd-BOPTA on the Hepatobiliary Phase in Hepatic Metastasis from Carcinoid Tumor - Case Report.

BACKGROUND Carcinoid tumor is the most frequent neuroendocrine tumor (NET) that causes liver metastases. One of the best methods to assess this type of pathology is magnetic resonance imaging with hepatocyte-specific contrast media with low molecular weight gadolinium chelate Gd-BOPTA. As these lesions do not contain hepatocytes, they present as hypointense on MRI in comparison with liver tissue which enhances this type of contrast.

[Ganglioneuroblastoma in a child with chronic abdominal pain - a case report].

Chronic abdominal pain is a very common complaint in the population of children and adolescents. In most cases, the usual cause are functional gastrointestinal disorders. However, in a few percent of children, the reason for persistent chronic stomach pain are organic diseases occurring in the gastrointestinal tract, as well as parenteral diseases, including uro-genital tract abnormalities, inflammation of the lower respiratory tract and cancer processes.

Radiomics - the value of the numbers in present and future radiology.

Radiomics is a new concept that has been functioning in medicine for only a few years. This idea, created recently, relies on processing innumerable quantities of metadata acquired from every examination, followed by extraction thereof from relevant imaging examinations, such as computer tomography (CT), magnetic resonance imaging (MRI), or positron emission tomography (PET) images, by means of appropriate created algorithms. The extracted results have great potential and broad possibilities of application.
