📌 3 Key Takeaways

🎯
Objective & Hypothesis:Aim: The aim of this study was to investigate whether renal veinvariations had an effect on apparent diffusion coefficient (ADC)values in diffusion magnetic resonance imaging (MRI).Methods: Images of 958 patients who underwent MRI betweenJanuary 2017 and October 2018 were retrospectively evaluatedfor renal vein variations based on the records obtained from theimage archive.
📊
Key Findings & Data:The ADC values of both kidneys weremeasured at low-high b values.Results: The ADC values in the left kidney were lower than inthe right kidney in both groups (2.04x10-3± 0.22x10-3 mm2/sec,1.96x10-3±0.17x10-3 mm2/sec, for the renal vein variation group;p=0.008 and 2.08x10-3±0.13x10-3 mm2/sec, 1.94x10-3±0.11x10-3mm2/sec, for the control group; p=0.0001).

Abstract

Aim: The aim of this study was to investigate whether renal veinvariations had an effect on apparent diffusion coefficient (ADC)values in diffusion magnetic resonance imaging (MRI).Methods: Images of 958 patients who underwent MRI betweenJanuary 2017 and October 2018 were retrospectively evaluatedfor renal vein variations based on the records obtained from theimage archive. Forty-six patients with renal vein variations andthirty patients of similar age and gender as the control groupenrolled in the study. The ADC values of both kidneys weremeasured at low-high b values.Results: The ADC values in the left kidney were lower than inthe right kidney in both groups (2.04x10-3± 0.22x10-3 mm2/sec,1.96x10-3±0.17x10-3 mm2/sec, for the renal vein variation group;p=0.008 and 2.08x10-3±0.13x10-3 mm2/sec, 1.94x10-3±0.11x10-3mm2/sec, for the control group; p=0.0001). However, no significantdifference was found between the renal vein variation and controlgroups in terms of the ADC values in both kidneys.Conclusion: Renal vein variations had no effect on renal ADCvalues in asymptomatic patients. Further studies can provideadditional information for symptomatic patient groups.

Özet

Amaç: Bu çalışmanın amacı, renal ven varyasyonlarının difüzyon ağırlıklı manyetik rezonans görüntülemede (MRG) görünür difüzyon katsayısına (GDK) etkisinin olup olmadığını araştırmaktadır. Yöntemler: Ocak 2017 ile Ekim 2018 tarihleri arasında abdominal MRG çekilmiş 958 hastanın tetkikleri renal ven varyasyonları açısından hastane görüntü arşivinden retrospektif olarak incelendi. Renal ven varyasyonu olan 46 hasta ve 30 hastadan oluşan kontrol grubunda yüksek ve düşük b değerlerinde her iki böbreğin GDK değerleri ölçüldü. Bulgular: Renal ven varyasyonu olan grupta ve kontrol grubunda sağ ve sol böbrek GDK değerleri arasında fark saptandı [2,04x10-3±0,22x10-3 mm2/sec, 1,96x10-3±0,17x10-3 mm2/sec; p=0.008 (varyasyonu olan grupta sağ ve sol böbrek, sırasıyla), 2,08x10-3±0,13x10-3 mm2/sec, 1,94x10-3±0,11x10-3 mm2/sec; p=0,0001, kontrol grubunda sağ ve sol böbrek, sırasıyla]. Sol böbrek GDK değerleri her iki grupta da sağ böbrekten daha düşüktü. Her iki böbrek GDK değerleri renal ven varyasyonu olan grupta ve kontrol grubunda benzerdi. Sonuç: Renal ven varyasyonu asemptomatik hastalarda böbrek GDK değerleri üzerinde herhangi etki göstermemektedir. Gelecekte semptomatik hasta gruplarıyla yapılacak çalışmalar ek bilgi verebilir
