Santral Sinir Sistemi Tümörlerinin Görüntülenmesi

Year 2018, Volume: 2 Issue: 1, 56 - 61, 12.03.2018

Abstract





















Çoğu santral sinir sistemi (SSS) tümörlerinin ve tümör
olmayan lezyonların oldukça benzer görünümler sergilemesinden dolayı rutin
Manyetik Rezonans Görüntüleme (MRG) sekanslarının özgüllükleri bunları ayırmada
yetersizdir. SSS tümörlerinin ayırıcı tanısında anahtar unsurlar, lezyonun
lokalizasyonu (intra- veya extra-aksiyel, infra- veya supra-tentoriyal) ile
birlikte hastanın yaşıdır. Multiparametrik MRG tekniklerini (Spektroskopi,
Difüzyon Ağırlıklı Görüntüleme, Difüzyon Tensor Görüntüleme, Perfüzyon Ağırlıklı
Görüntüleme, Fonksiyonel MRG), tümörün mikroskobik ve fonksiyonel davranışına ilişkin
(hücresel yoğunluk, neo-vaskularizasyon, kapiller sızıntı ve metabolitler gibi)
bilgiler sunar. İleri multiparametrik görüntüleme teknikleri SSS tümörü olan
hastaların teşhisi, yönetimi ve takibinde kesin ve güvenilir invaziv olmayan
bir yöntem sunar.

Imaging of Central Nervous System Tumors

Abstract











Many Central
Nerve System (CNS) tumors and even non–tumoral lesions may show a very similar
imaging appearance; therefore,
routine Magnetic Resonance Imaging (MRI) are lack of specificity to
differentiate these lesions. The key points in the differential diagnosis of
CNS tumors are the location of the lesion (intra- or extra-axial, infra- or
extra-tentorial) and the age of the patient. Multiparametric MRI techniques
(Spectroscopy, Diffusion Weighted Imaging, Diffusion Tensor Imaging, Perfusion
Weighted Imaging, Functional MRI) reveal the information about the microscopic
and functional behaviors of the tumor (cellular density, neo-vascularization,
capillary leakage and metabolites, etc). Advanced multiparametric imaging tools
support the diagnosis, management and follow-up of patients with CNS tumors as
an accurate and reliable noninvasive technique.
