Echo-reading is a practical therapeutic tool which has been proposed for use in stuttering, most especially when the functions of rhythm and association are disrupted in stuttered speech. After a period of preparation in which the mechanical work involved in speech is integrated, it is proposed that there should follow a period of listening and association, which serves to re-establish the spoken word with its meaning and expressivity. The subject undergoes rehabilitation in a living language which is correlated with the imagination, and with that Other quality which always forms a part of speech.

No method of evaluating transthoracic echocardiograms (TTE) image quality (IQ) has been validated. Furthermore, structural echo lab elements impacting IQ are unknown. We sought to develop and validate a TTE IQ grading tool and determine patient and echo lab features associated with IQ.

Purpose: The primary purpose of this study was to evaluate the accuracy of an MR-thermometry sequence for monitoring prostate temperature. The secondary purposes were to analyze clinical and technical factors that may affect accuracy and testing the method in a realistic setting, with MR-guided Laser ablation on an ex vivo muscle sample.
Materials And Methods: An ex vivo muscle sample was subjected to Laser ablation while using a two-dimensional multislice segmented echo planar imaging sequence for MR thermometry.

Background: Ultrashort echo time (UTE) allows imaging of tissues with short relaxation times, but it comes with the expense of long scan times. Magnitude images of UTE magnetic resonance imaging (MRI) are widely used in pulmonary imaging due to excellent parenchymal signal, but have insufficient contrast for other anatomical regions of the thorax. Our work investigates the value of UTE phase images (UTE-Ps)-generated simultaneously from the acquired UTE signal used for the magnitude images-for the detection of thoracic lymph nodes based on water-fat contrast.

Purpose: To develop and validate a 3D turbo spin-echo (TSE)-compatible approach to enhancing black-blood (BB) effects while preserving T weighting and overall SNR.
Methods: Following the excitation RF pulse, a 180° RF pulse sandwiched by a pair of flow-sensitive dephasing (FSD) gradient pulses in the phase- (y) and partition-encoding (z) directions, respectively, is added. The polarity of FSD gradients in z direction is toggled every TR, achieving an interleaved FSD (iFSD) configuration in y-z plane.

Introduction: The apparent diffusion coefficient (ADC) from diffusion MRI provides critical insights into tissue microstructure and is influenced by various b-values. This study aimed to evaluate the impact of multiple b-values on ADC measurements using a multicenter observational approach with different MRI scanners and phantoms.
Methods: The study utilized a liquid isotropic phantom across eight different 1.
