The significant advances in magnetic resonance imaging (MRI) hardware and software, sequence design, and postprocessing methods have made diffusion-weighted imaging (DWI) an important part of body MRI protocols and have fueled extensive research on quantitative diffusion outside the brain, particularly in the oncologic setting. In this review, we summarize the most up-to-date information on DWI...
The goal of this work is to develop software that enables the rapid implementation of custom MRI spectrometers using commercially-available software defined radios (SDRs). The developed gr-MRI software package comprises a set of Python scripts, flowgraphs, and signal generation and recording blocks for GNU Radio, an open-source SDR software package that is widely used in communications research...

هدف: برای به دست آوردن بیشترین فواید از جراحی stn-dbs، هدف باید به دقت معین شود. برای سالها، بهترین روش آناتومیک برای هدف¬یابی stn مورد چالش بوده است. هدف از این مطالعه، تعیین دقیقترین روش مکان¬یابی آناتومیک stn (هدف¬یابی on-screen mri مستقیم، در نماهای کرونال و اگزیال؛ هدف¬یابی کامپیوتری با نرم¬افزار در نماهای کرونال و اگزیال، هدف¬یابی بر اساس اطلس شالتربراند-وارن، و روش هدف-یابی ترکیبی) در مق...
Initially, the role of MRI for assessment of prostate cancer was limited to staging patients with biopsy proven disease. However, along with the expansion of treatment options for prostate cancer and advances in MR technology (software, hardware, and 3T), clinical applications of prostate MRI now include detection, localization, active surveillance, and image guidance for biopsy and surgery. Tr...
Background An MRI-compatible 12-lead ECG platform, equipped with MRI-gradient induced-voltage removal hardware and magneto-hydrodynamic voltage removal software [1], was previously applied to physiological monitoring and synchronization of cardiac imaging of patients inside MRI. This approach had limited success for highduty-cycle [(total Gradient-ramp-time per R-R)/(R-R time) >20%] MRI sequenc...
Concurrent recording of electroencephaologram (EEG) during magnetic resonance imaging (MRI) holds promise for both basic neuroscience studies and clinical diagnostic and monitoring applications. However, in order to realize the full potential of this technique, a number of methodological challenges related to the physics of the MRI environment must first be solved. In this Chapter, we overview ...
Magnetic resonance imaging (MRI) provides high resolution multi-parametric imaging, large soft tissue contrast, and interactive image updates making it an ideal modality for diagnosing prostate cancer and guiding surgical tools. Despite a substantial armamentarium of apparatuses and systems has been developed to assist surgical diagnosis and therapy for MRI-guided procedures over last decade, t...
mri of the breast has evolved as a non-invasive imaging modality and is ideally suited for several indications e.g. pre-operative staging and screening in women at increased risk for breast cancer. the widespread use opens also the discussion on over-diagnosis if only 20 - 30 out of 100 mri - guided breast biopsies lead to the diagnosis of breast cancer. thus mri based strategies are needed to ...
