    An adult situs ambiguous case with polysplenism
    (2006) Özkurt, H.; Narin, B.; Arman, A.; Tasali, N.; Çelik, L.
    Situs ambiguous is a rare anomaly that is characterised by abnormal arrangement of abdominal organs with congenital heart diseases. Patients rarely survive beyond first decade of life as this anomaly generally coexists with cyanotic heart diseases. The correct recogniation and characterisation of cases is important for planning surgical, radiologic and endoscoping interventions. In this case we present an incidentally diagnosed case with midline located liver, multiple spleens and stomach in the right upper quadrant, interruptured inferior vena cava with azygos continuation. The heart was left sided and there was no sign of congenital cardiac anomaly. Hereby we present this case as it was found incidentally at adult age and there was no accompanying congenital heart anomaly.

    Correlation between breast density in mammography and background enhancement in MR mammography
    (SPRINGER, 2010) Cubuk, R.; Tasali, N.; Narin, B.; Keskiner, F.; Celik, L.; Guney, S.
    Purpose. We aimed to analyse the influence of mammographic breast density on background enhancement (BE) at magnetic resonance (MR) mammography in pre- and postmenopausal women. In addition, we questioned predictability of contrast-enhancement dynamics of normal fibroglandular tissue (NFT) at MR mammography according to mammographic breast density. Materials and methods. Twenty-six patients (mean age 51.54 +/- 11.5 years; range 37-79 years) who underwent both MR mammography and conventional mammography were included in this retrospective study. Fourteen patients were premenopausal and 12 were postmenopausal. The ethics committee of our institution approved the study. The mammograms were retrospectively reviewed for overall breast density according to the four-point scale (I-IV) of the Breast Imaging Reporting and Data System (BI-RADS) classification. Two radiologists, who were unaware of the clinical data, separately assessed the MR mammography images. Images were assessed for enhancement kinetic features (enhancement kinetic curve and the early-phase enhancement rate) and BE. MR mammography and conventional mammography findings were compared according to BI-RADS breast density category and menopausal status. Results. Percentage of increased signal intensity values during the first minute did not change according to mammographic breast density, and the mean early-phase enhancement rate scores were similar among breast density groups (p=0.942). There was no significant difference between pre- and postmenopausal groups. Enhancement kinetic features of the different groups based on BI-RADS breast density category and menopausal status were similar. There was no correlation between breast density and BE in either premenopausal (p=0.211) or in postmenopausal (p=0.735) groups. Conclusions. We determined no correlation between mammographic breast density and so-called BE in MR mammography in either premenopausal or postmenopausal women. NFT at MR mammography cannot be predicted on the basis of mammographic breast density.
