Abstract

The Role of Diffusion MR Imaging in Detecting Cerebral Microstructural Changes: Initial Findings in Pediatric Patients with Neurofibromatosis Type 1 Objective: BBrain lesions in Neurofibromatosis type 1 include optic pathway gliomas, cerebral astrocytomas and focal hyperintense areas in T2-weighted MRI. MR with diffusion-weighted imaging (DWI) is used to detect white matter abnormalities. The purpose of this study was to eva- luate the differences in apparent diffusion coefficient (ADC) values between normal appearing regions in the NF1 pati- ents and control group. Material and Methods: Ten children (3-15 years old) with NF1 and 10 control subjects were evaluated. The MRI exa- mination consisted of routine imaging and diffusion we- ighted imaging (DWI). Six distinct locations (frontal and parieto-occipital white matter, basal ganglia, thalamus, corpus callosum and midbrain) were selected for the analy- sis. The ADC values were calculated directly from these automatically generated ADC maps with ROI. Results: There were statistically significant differences between normal appearing region in the NF1 patients and control group in the ADC values obtained from midbrain and thalamus. Conclusion: Diffusion MRI allows the characterization of microstructural abnormalities even in some brain regions that appear normal in conventional MR sequences. This will be guiding us in the diagnosis and follow-up of NF-1 disease.

Özet

Amaç: Nörofibromatozis tip 1’deki beyin lezyonları, optik gliomlar, serebral astrositomlar ve T2 ağırlıklı manyetik rezonans (MR) sekanslarında fokal hiperintens lezyonlardır. Difüzyon ağırlıklı MR görüntüleri ak madde anormalliklerini tespit etmede kullanılır. Bu çalışmadaki amacımız NF-1 tanısı almış çocuklarda normal görünen beyin parankiminde, görünen difüzyon katsayısı (ADC) ile kontrol grubundaki aynı yaşta bilinen bir hastalığı olmayan çocukların ADC değerlerini karşılaştırmaktır. Gereç ve Yöntemler: Nörofibromatozis tip 1 tanısı almış 3-15 yaş arası 10 çocuk hasta ve 10 kontrol olgu değerlendirildi. MR tekniği rutin sekanslar ve difüzyon ağırlıklı sekanslardan oluşturuldu. Frontal, parieto-ooksipital beyaz cevher, bazal ganglionlar, talamus, korpus kallozum ve beyin sapı yapıları ADC haritalamasında altı bölge olarak incelendi. ADC değerleri ROI kullanarak yapıldı. Bulgular: Olgu grubunun beyin sapı ve talamus ADC ortalaması, kontrol grubundan istatistiksel olarak anlamlı düzeyde yüksektir (p<0.05). Sonuç: Difüzyon MR, konvansiyonel MR sekanslarında normal görünen alanlarda bile, NF-1 hastalarında mikrostrüktürel anomalileri tanımaya yardımcı olur. Bu durum NF-1 hastalığının tanı ve takibinde yararlı olabilir.
