Although the study found that pulsation artifacts were reduced and upper thoracic structures were thereby better delineated, the TSE T1 technique showed better contrast between lymph nodes and fat.…”

Detection and differentiation of lymph node disease in the head and neck can be very difficult but is of importance for staging and treating head and neck (H&N) tumors. This topic is therefore a source of much ongoing study. With constantly evolving imaging technology, there is an ongoing need for evaluation of both new and improved techniques, and potential new uses of current modalities. CT, MRI, and PET are examined in this article, with a focus on H&N disease processes and the technical aspects of imaging. The goal of this review article is to bring the reader up to date on pertinent articles in advanced imaging of H&N lymph node disease from the year 2013.

“…Previous clinical studies have shown that a BLADE acquisition can reduce pulsation artifacts from the transverse and sigmoid sinuses at T 2 -FLAIR imaging 6 and contrast-enhanced T 1 -FLAIR in adults. 8 The reduction of this artifact from the venous sinus was also achieved in non-contrast-enhanced T 1 -FLAIR-BLADE in children.…”

“…The clinical use of T 1 -FLAIR-BLADE has been reported with or without gadolinium enhancement for brain imaging in adults 6,8,9 and with gadolinium contrast for brain imaging in children. 10 However, we believe the utility of T 1 -FLAIR-BLADE as a non-contrast-enhanced T 1 -weighted sequence in pediatric patients has not been well established.…”

Purpose: In magnetic resonance imaging of the brain, BLADE is used to compensate for head motion. The technique focuses mainly on acquisition of T 2 -weighted or contrast-enhanced T 1 -weighted images in adults; its utility for nonenhanced T 1 -weighted imaging in children is not well established. We compared the quality of T 1 -weighted ‰uid-attenuated inversion recovery brain imaging with BLADE (T 1 -FLAIR-BLADE) to that of conventional spin-echo T 1 -weighted imaging (T 1 -SE) in pediatric patients who cannot stay still during MR imaging.Materials and Methods: Our investigation included a volunteer study and a retrospective clinical study. Six healthy adult volunteers underwent scanning to compare the contrast of T 1 -SE, T 1 -weighted ‰uid-attenuated inversion recovery imaging (T 1 -FLAIR), and T 1 -FLAIR-BLADE at both 1.5 and 3 tesla. Comparison was based on scores assigned independently by 2 blinded observers and by calculated contrast-to-noise ratio. The clinical study included 20 children who underwent both T 1 -SE and T 1 -FLAIR-BLADE at either 1.5 (n＝9) or 3 T (n＝11). On each sequence, 2 blinded observers independently scored visualization of the cerebral gyri and contrast between gray and white matter. We compared scores between sequences separately for 1.5 and 3T using Wilcoxon signed-rank tests.Results: At both 1.5 and 3T, contrast was better using T 1 -FLAIR and T 1 -FLAIR-BLADE than T 1 -SE in volunteers, and overall scores were signiˆcantly higher with T 1 -FLAIR-BLADE (Pº0.05) than T 1 -SE in the clinical study.Conclusion: T 1 -FLAIR-BLADE may be superior to T 1 -SE in demonstrating brain structures in children who cannot stay still and may be used to supplement or replace T 1 -SE when T 1 -SE is insu‹cient for patient motion.

Results: More than 23 lesions were detected by contrastenhanced T1-FLAIR SENSE when it was compared with contrast-enhanced T1W SE. Lesion-background and lesion-CSF CNR were compared. There was no significant difference between them (p>0.05). Conclusion: In this study we concluded that contrast-enhanced T1W FLAIR SENSE can take place in the routine examinations to detect brain masses and to reduce artifacts.

Eğer MRG tetkiki uygun bir protokolde uygulanmış ve deneyimli bir radyolog tarafından beyin tümörü varlığı açısından negatif olarak yorumlanmışsa, beyin tümörü olasılığı güvenli bir şekilde dışlanabilir. Tümör mevcut ise, tümörün kesin yerleşimi ve özellikleri tanımlanmalıdır.
