Clinical and biochemical characteristics are shown in table 1 and echo variables are shown in table 2. The mean blood pressure constitutes a mixture of blood pressure under treatment and untreated patients.
Whereas Doppler myocardial imaging allows more precise discrimination of the phase of diastolic dysfunction, Sturgess et al. clearly demonstrated that relatively simple echo variables, as left ventricular end-systolic volume, retain their clinical and even prognostic value and therefore should not be forgotten whenever performing an echocardiographic investigation.
For quantitative bi-exponential T2* assessment, a multi-echo, variable echo time (me-vTE) sequence was obtained, with sequentially shifted echo times.
3D turbo spin echo with variable flip angle.
These themes partially echoed those variables included in standard item-sets and Smith et al. [ 3] review of Cochrane reviews, but there were many which stood apart from these 'standard' outcomes.
The results of this study suggest that the variable echo time sequence based on a gradient echo is suitable for bi-component analysis of T2* in the human Achilles tendon in vivo.
A new functional MRI protocol that integrates variable echo time (TE) acquisition and a block-design paradigm is proposed and evaluated with finger-tapping motor task.
Two MRI approaches were used: spin echo (SE) and variable tip angle gradient echo (VTA-GE) readouts.
A single-slab 3D T2-weighted turbo spin echo sequence with variable flip angles (SPACE; Mugler et al., 2000) in combination with parallel imaging was used to simultaneously achieve a high-image resolution of ∼500 μm, high sampling efficiency and short scan time while maintaining a sufficient signal-to-noise (S/N) ratio (SNR).
The creature was rewarded with a mealworm whenever it moved toward the variable echoes rather than to the side that produced regularly spaced echoes.
Typically, tophi have homogeneous low signal intensity on T1-weighted spin-echo images but variable signal intensity on T2-weighted images.
