(4) believed that with an appropriate scanning sequence
, the magnetic resonance imaging can easily show the esophageal pouch, further confirming esophageal atresia.
However, the team advises that in clinical practice, LUS should not be limited to a fixed scanning sequence
. Occasionally, the use of extended view function (XTD-View) can be brought about in practice.
Bright-blood and black-blood MRI examination was carried out by using 8-channel cervical surface phased-array coil (Shanghai Chenguan Company, China), the scanning sequence
was FSE dual inversion recovery T1W, proton density weighted (PDW), T2W and three-dimensional time-of-flight (3D-TOF) gradient recalled echo, and the parameters were listed in [Table 1].
(2) Field preparation: including field reinforcement, preparation for marked drawings of the area to be scanned, and planning the scanning sequence
. Field reinforcement is required because the 3D scanning instrument is especially sensitive, even slight shaking will affect data quality.
Electrocardiogram (ECG) gating is done almost without exception, and patients are often asked to hold their breath for each scanning sequence
to minimise respiratory motion artefacts.
A scanning sequence
of a body segment consists of a number of individual slices that together are called an image volume.
When detected, the Artemis terminal stopped its scanning sequence
and the optical link between the two vehicles was maintained for pre-programmed periods of between four and 20 minutes.
This scanning sequence
is similar to the standard spin echo sequence without the 180 [degrees] pulse. (See Fig.
At the end of each of the seven scanning sequences
, data is automatically extracted for each element and a full-scale report is generated and can be printed and shared immediately with the car's racing team.--M.A.
The scanning sequences
were set as AX T1 weighed image (WI), T2WI, T2 fluid-attenuated inversion-recovery (FLAIR) and diffusion weighted imaging (DWI).
Today, because of higher image resolution and additional scanning sequences
added in recent years, you may need to review more than 350 images when interpreting a contrast-enhanced brain MRI.
