Abstract

Aim/background: To assess the role of diffusion weighted imaging (DWI) in diagnosis of post-traumatic splenosis.Methods: We retrospectively evaluated 26 post-traumatic splenectomy patients (19 men and 7 women; mean age 29.4 years) with abdominal mass(es) suspicious for splenosis on magnetic resonance imaging (MRI) including DWI. The thirteen of these patients had scintigraphic imaging. The other thirteen patients had only MRI. In control group, 30 individuals (20 men and 10 women; mean age 33.1 years) were enrolled for investigating the mean ADC value of spleen. The b value of 1000 s/mm2 was preferred due to perfusion contamination of low b values.Results: The mean ADC value of masses and spleen were 0.790±0.087x10-3mm2/s and 0.8075±0.084x10-3mm2/s respectively. All of the masses appeared hyperintense on DWI and hypointense on ADC map, and the mean ADC value of masses were showed similarity with the mean ADC value of spleen. The thirteen patients showed positive Results for splenosis on scintigraphy. In addition to medical history and conventional MRI of the masses, DWI allowed the diagnosis of splenosis to be assigned in all patients.Conclusion: Measurement of the mean ADC value in suspected post-traumatic splenosis patients otherwise healthy may be an indicator in the determination of splenosis as an alternative imaging modality to scintigraphy

Özet

Posttravmatik splenektomi hastalarındaki splenozisin noninvaziv tanısında sintigrafiye alternatif bir görüntüleme yöntemi: Difüzyon ağırlıklı görüntüleme Amaç: Bu çalışmadaki amacımız, posttravmatik splenozis tanısında difüzyon ağırlıklı görüntülemenin (DAG) rolünü değerlendirmektir. Yöntem: Çalışmamızda, splenozis açısından şüpheli batın kitlesi bulunan 26 posttravmatik splenektomi olgusunun (19 erkek ve 7 kadın; ortalama yaş 29.4 yıl) DAG sekansı da içeren manyetik rezonans (MR) görüntüleme Bulguları geriye dönük olarak değerlendirildi. Onüç olgunun sintigrafik tetkiki de mevcuttu. Kontrol grubunda ise 30 kişinin (20 erkek ve 10 kadın; ortalama yaş 33.1 yıl) dalak ortalama apparent diffusion coefficient (ADC) değerleri hesaplandı. Düşük b değerindeki perfüzyon kontaminasyonunu engellemek için, 1000 s/mm2'lik b değeri kullanıldı. Bulgular: Kitleler ve dalağın ortalama ADC değerleri sırasıyla, 0.790±0.087x10-3mm2/s ve 0.8075±0.084x10-3mm2/s olarak bulundu. Tüm kitleler, DAG'de hiperintens, ADC haritasında hipointens olarak izlendi. Kitlelerin ortalama ADC değeri ile dalağın ortalama ADC değeri benzerlik gösterdi. Onüç olguda sintigrafi sonuçları splenozis yönünden pozitifti. DAG, medikal hikaye ve MR görüntüleme Bulgularına ek olarak splenozis tanısının koyulmasına katkı sağladı. Sonuç: Ortalama ADC ölçümü, bilinen bir hastalığı olmayan şüpheli posttravmatik splenozis olgularının tanısında, sintigrafiye alternatif bir görüntüleme modalitesi olabilir.
