    Diffusion-weighted magnetic resonance imaging and magnetic resonance spectroscopy features of abdominal viscera in a patient with Gaucher's disease
    (Malaysian Journal of Medical Sciences, 2014) Kalayci T.O.; Erdem G.; Kutlu R.; Kahraman A.; Alkan A.
    A 46-year-old woman with Gaucher's disease (GD) consulted our clinic for abdominopelvic magnetic resonance imaging (MRI), as physical examination had revealed hepatosplenomegaly. Upper abdominal MRI showed massive hepatosplenomegaly and innumerable hypointense splenic nodules on T1-weighted images. Diffusion-weighted MRI (DW-MRI) and magnetic resonance spectroscopy (MRS) were performed to liver parenchyma and splenic nodules. MRS revealed lactate, lipid, acetate, and alanine peaks in splenic nodules, and choline, creatine, lipid, myo-inositol-glycine, and lactate peaks in the liver parenchyma. The DW-MRI showed diffusion restriction in splenic nodules. It was concluded that MRI is a reliable method for the diagnosis and follow up of GD. Coupling DW-MRI and MRS allows quantitative evaluation, thereby increasing the efficacy of the method. This is the first report in the literature presenting advanced abdominal MRI findings in GD. © Penerbit Universiti Sains Malaysia, 2014.

    The effect of the intercondyler notch width index on anterior cruciate ligament injuries: A study on groups with unilateral and bilateral ACL injury
    (SAGE Publications Ltd, 2014) Görmeli C.A.; Görmeli G.; Öztürk Y.B.; Özdemir Z.; Kahraman A.
    Objectives: To evaluate the relationship of the intercondylar notch width with unilateral and bilateral ACL injury by using MR images. Methods: The intercondylar notch width index was measured on the MR images of 18 patients with a bilateral ACL injury, 38 patients with a unilateral ACL injury and 53 healthy subjects with a normal ACL and the results of all groups were compared with each other. Results: The mean NWI values were 0.227 (±0.008) in bilateral injured; 0.245 (±0.009) in unilateral injured and 0.272 (±0.01) in control groups and 0.251(±0.01) in unaffected side of the unilateral group. There were statistically significant differences in intercondylar notch width index (NWI) values between all groups and there was a significant difference between the affected and the unaffected sides in group with unilateral ACL injury. A cutoff value of 0.25 for NWI gave an odds ratio of 26.5 for bilateral and 3.23 for unilateral ACL injuries. Conclusion: The finding that NWI is significantly narrowed in patients with bilateral and unilateral ACL tears compared with the healthy controls suggest a relationship between a narrow NWI and an increased risk of ACL injury. The patients with a narrow NWI should also be screened contralaterally for assessment of ACL injury risk on the other knee. So, specialized training programmes for the people with narrow NWI can be prepared for preventing ACL injuries. © The Author(s) 2014.

    Green pea response to deficit irrigation rates under semi-arid climatic conditions
    (National Centre for Agrarian Sciences, 2015) Dogan E.; Rat I.; Kahraman A.; Ipek I.S.
    A study was carried out in the 2008 and 2009 cropping seasons, to determine the supplemental irrigation effect on yield and yield components of green pea under the semi-arid climatic conditions of Harran Plain, Sanliurfa, Turkey. Irrigation treatments included I0 (dryland), I25, I50, I75, I100 (full irrigation), and I125 (over irrigation) and scheduled based on soil moisture measurements. Annual precipitation was about 200 mm in first year and 275 mm in the second year. In addition, the full irrigation treatment plot received 235 and 195 mm in respective years. Almost all of the measured crop parameters including number of pod per plant, 1000- seed weight, biomass and seed yield parameters were increased by irrigation treatments up to full irrigation except number of branch as per plant. Biomass values ranged in general from 5500 (dry land) to 11500 (fully irrigated) kg ha?1, while seed yield varied from 1300 (dry land) to 3450 (full irrigated) kg ha?1. Therefore it is recommended to fully irrigate the green pea crop for optimum biomass and seed yield when irrigation water is available. Otherwise, considerable yield reduction can be anticipated. © 2015, National Centre for Agrarian Sciences. All rights reserved.
