Significats de planar imaging en anglès

Current cardiovascular ultrasound mainly employs planar imaging techniques to assess function and physiology.

In 15% of patients, SPECT detected cortical defects not appreciated on planar imaging.

Echo planar imaging sequence was performed at rest, during dorsal flexion and during plantar flexion.

The biodistribution was studied by measurements of dissected tissues as well as by PET and planar imaging.

These techniques require no special pulse sequence modifications and can be applied to any complex-valued echo planar imaging data set.

The measurements were compared to DWI using a spin-echo sequence and a single-shot echo planar imaging (EPI) sequence.

Magnetic resonance imaging was performed with 1.5T units using diffusion-weighted spin-echo-type echo planar imaging (DWI).

Magnetic resonance imaging (MRI) techniques sensitive to changes in cerebral blood flow and blood oxygenation were developed by high-speed echo planar imaging.

Methods: The study included 271 consecutive tumor patients in whom planar imaging and two-bed position SPECT of the spine and the pelvis had been performed.

We show the feasibility of single breath-hold volumetric imaging of the heart using a three-dimensional (3D) segmented echo planar imaging (EPI) pulse sequence.

Our methodology uses high-speed "single-shot" or echo planar imaging techniques, which provide the necessary temporal resolution for mapping the rapid cerebral transit of contrast agents.

In human volunteer studies, motion estimates were obtained from echo planar imaging and cloverleaf navigator sequences every 3 s and 20 ms, respectively.

Results: On conjugated planar imaging, radioactivity was concentrated on the tumor (effective half-life, 16.2 hours), and mean radiation dose to the tumor was 147.7 Gy.
