Comparative analysis of methods for extracting vessel network on breast MRI images
(2017)Digital processing of MRI images aims to provide an automatized diagnostic evaluation of regular health screenings. Cancerous lesions are proven to cause an alteration in the vessel structure of the diseased organ. Currently ... -
Cyclopia and exadactyly: CT and MRI findings
(1999)Cyclopia is a congenital abnormality consisting of fused orbits and a single eye and is the most extreme form of alobar holoprosencephaly. The present case describes the CT and MRI findings in the skull of a 33-week-old ... -
Diagnostic performance of quantitative diffusion tensor imaging for the differentiation of breast lesions at 3 T MRI
(2019)Background: Conventional breast magnetic resonance imaging (MRI), including dynamic contrast-enhanced MR mammography, may lead to ambiguous diagnosis and unnecessary biopsies. Purpose: To investigate the contribution of ... -
Differences in graft orientation using the transtibial and anteromedial portal technique in anterior cruciate ligament reconstruction: a magnetic resonance imaging study
(2009)The purpose of this study was to evaluate differences in graft orientation between transtibial (TT) and anteromedial (AM) portal technique using magnetic resonance imaging (MRI) in anterior cruciate ligament (ACL) ... -
The electromagnetic environment of Magnetic Resonance Imaging systems. Occupational exposure assessment reveals RF harmonics
(2015)Magnetic Resonance Imaging (MRI) systems played a crucial role in the postponement of the former occupational electromagnetic fields (EMF) European Directive (2004/40/EC) and in the formation of the latest exposure limits ... -
