MRI FLOW ARTIFACT & GIT MOTION ARTIFACT REDUCTION

Flow Artefact Reduction



Gradient Motion Nulling
  • GMR, Flowcomp
  • Extends minimum Te degrades T1 contrast and slices/TR
  • Minimal value on T2 images only
Spatial Saturation
  • Removes Flow related Enhancement
  • Time penalty depends on sequence design
  • May be 5 msec x slabs or 5 msec x slabs x slices / n (n = 1-3)
  • Use whenever possible especially in GRE sequences
  • Superior sat slab more useful than inferior


Gut Motion Artefact reduction

Reduce gut motility
  • Fast totally for 6 hours prior to exam (cheap & effective
  • Buscopan or Glucagon (expensive & side effects)

    There are a lot of misconceptions about what it means to be living with Herpes simplex virus (HSV). Ultimately, everyone’s lives are different – how you cope with your diagnosis and how you move forward is up to you.

    The 21st of June 2015 was the day I was diagnosed with Herpes simplex virus (HSV). l was so worried that I cried out endlessly. On the way there I was crying and shaking the steering wheel, I just didn’t know what I should do.

    After that day, my depression was at all-time high, but slowly, I started to do my own research, looking at what I should do next and then last month, i came across a website which was about cure for Herpes simplex virus (HSV) and other STD's.

    I took the contact details from the website and contact the doctor (Dr. Francisco. B.), and after much inquiry, we came to a conclusion and she sent a herbal medicine to me through the courier delivery service, and she also gave me guidelines on how to take the medicine.

    After 9 days of taking the medicine, i discovered that all painful sores in the genital area, the itching, painful urination and tender lumps in the groin was no more, and i went for a medical test, and i was so amazed to see my test result showing NEGATIVE. I then went to another hospital, and my test result is still showing NEGATIVE till date.

    I think life has given me another chance to be happy and free, I now do what I can to inspire others through these battles. For anyone out there affected with such disease please contact Dr. Francisco .B. with the below link;
