RATIONALE AND OBJECTIVES To assess the feasibility of quantitative T2* mapping at 3.0 T for prostate cancer detection and to investigate the use of T2* values to characterize tumor aggressiveness, with whole-mount step-section pathologic analysis as the reference standard. MATERIALS AND METHODS Prostate multiecho T2* was performed in 55 consecutive patients with prostate cancer using a multis...

We present the open-source tool T2, the first public release from the TERMINATOR project [8]. T2 has been extended over the past decade to support automatic temporal-logic proving techniques and to handle a general class of user-provided liveness and safety properties. Input can be provided in a native format and in C, via the support of the LLVM compiler framework. We briefly discuss T2’s arch...

BACKGROUND According to the Response Assessment in Neurooncology (RANO) criteria, significant nonenhancing signal increase in T2-weighted images qualifies for progression in high-grade glioma (T2-progress), even if there is no change in the contrast-enhancing tumor portion. The purpose of this retrospective study was to assess the frequency of isolated T2-progress and its predictive value on su...

امروزه با پیچیده تر شدن محصولات تولیدی، لازم است که کیفیت محصول در تمامی جوانب آن دیده شود، با توجه به وجود بیش از یک مشخصه کیفی در محصول، همه مشخصه ها باید مجموعاً با هم مطالعه شود تا کنترل آن محصول به درستی صورت گیرد. در نمودارهای کنترل چند متغیره، کنترل چند متغیر کیفی به طور همزمان در یک نمودار انجام می‎گیرد .هر چند روش ‎های چند متغیره مختلفی وجود دارد، اما باور بر این است که یک روش کنترلی مب...

OBJECTIVE The purpose of this study was to estimate the T2* relaxation time in breast cancer, and to evaluate the association between the T2* value with clinical-imaging-pathological features of breast cancer. MATERIALS AND METHODS Between January 2011 and July 2013, 107 consecutive women with 107 breast cancers underwent multi-echo T2*-weighted imaging on a 3T clinical magnetic resonance ima...

OBJECTIVE The objective of our study was to compare T2-weighted MRI alone and T2 combined with diffusion-weighted imaging (DWI) for the localization of prostate cancer. SUBJECTS AND METHODS T2-weighted imaging and DWI (b value = 600 s/mm2) were performed in 49 patients before radical prostatectomy using an endorectal coil at 1.5 T in this prospective trial. The peripheral zone of the prostate...

BACKGROUND AND PURPOSE Fluid-attenuated inversion recovery hyperintense vessels in stroke represent leptomeningeal collateral flow. We presumed that FLAIR hyperintense vessels would be more closely associated with arterial stenosis and perfusion abnormality in ischemic stroke on T2-PROPELLER-FLAIR than on T2-FLAIR. MATERIALS AND METHODS We retrospectively reviewed 35 patients with middle cere...

Technical limitations imposed by resolution and B1 homogeneity have thus far limited quantitative in vivo T2 mapping of cartilage to the patella. The purpose of this study is to develop T2 mapping of the femoral/tibial joint and assess regional variability of cartilage T2 in the knee. Quantitative in vivo T2 mapping of the knee was performed on 15 asymptomatic adults (age, 22-44) using a 3T MR ...
