“…We did not evaluate intratumoral nodular or solid positive enhancement on susceptibility-weighted images after contrast material injection in this study because intratumoral hypointensity and positive abnormal enhancement around the tumor seemed to be of value with the clinical use of SWI, and contrast-to-noise ratio of postcontrast 3D T1-weighted images was statistically superior to that of post-contrast SW images [21]. Moreover, we referred to the phase images of SWI and CT images (if available) to differentiate tumor vasculature from calcifications [22,23].…”

“…Available literature concerning evaluation of brain tumors using SWI sequence was analyzed [9,10,17–20] and no reports were found where the authors would propose any kind of objective method for evaluating brain tumor vascularization through SWI application. The results were based only on visual assessment by neuroradiologists.…”

SummaryBackground:Susceptibility weighted imaging (SWI) is a novel MRI sequence which demonstrates the susceptibility differences between adjacent tissues and it is promising to be a sequence useful in the assessment of brain tumors vascularity. The aim of our study was to demonstrate usefulness of SWI in evaluation of intratumoral vessels in comparison to CET1 sequence in a standardized, objective manner.Material/Methods:10 patients with supratentorial brain tumors were included in the study. All of them underwent conventional MRI examination with a 1,5 T scanner. SWI sequence was additionally performed using the following parameters: TR 49 ms,TE 40 ms. We used authors’ personal computer software – Vessels View, to assess the vessels number.Results:Comparison of SWI and CET1 sequences was performed using our program. Analysis of all 26 ROIs demonstrated predominance of SWI in the amount of white pixels (vessel cross-sectional) and a similar number of elongated structures (blood vessels).Conclusions:To conclude, the results of this study are encouraging; they confirm the added value of SWI as an appropriate and useful sequence in the process of evaluation of intratumoral vascularity. Using our program significantly improved visualization of blood vessels in cerebral tumors. The Vessel View application assists radiologists in demonstrating the vessels and facilitates distinguishing them from adjacent tissues in the image.

“…Our previous study also showed that the diagnostic performance of SWI for grading gliomas was comparable with that of DSC perfusion MR imaging (80). It has also been acknowledged that CE-SWI might offer additional information in the evaluation of brain tumors by depicting contrast enhancement as well as a greater multitude of susceptibility signals than non-contrast SWI (82). …”

Among the currently available brain tumor imaging, advanced MR imaging techniques, such as diffusion-weighted MR imaging and perfusion MR imaging, have been used for solving diagnostic challenges associated with conventional imaging and for monitoring the brain tumor treatment response. Further development of advanced MR imaging techniques and postprocessing methods may contribute to predicting the treatment response to a specific therapeutic regimen, particularly using multi-modality and multiparametric imaging. Over the next few years, new imaging techniques, such as amide proton transfer imaging, will be studied regarding their potential use in quantitative brain tumor imaging. In this review, the pathophysiologic considerations and clinical validations of these promising techniques are discussed in the context of brain tumor characterization and treatment response.
