| 3T imaging parameters |
At 3T the T1 time is longer (so the TR should also be longer) and the T2 time is shorter (TE can be shorter). However, when we got a 3T machine we tested different TR and TE's and found out that in practice the useful range don't has a big difference from that of a 1.5T MR system.
The contrast looks a bit different - that's normal.
In addition, ask the manufacturer.
There are a lot of other parameters that affect the contrast in 3T.
Hope this will help

| Metalic particles into the cornea |
Dear Friends:
We are working in a Ophthalmology Department at Institut Universitari Dexeus-USP in Barcelona.
We received a patient who was treated for myopia some time ago using a LASIK technique ( Laser In situ Keratomileusis) as you probably know, cornea was sliced and lasered using a microkeratome however blade oscilation in the past eventually spread into the interface particles comming from steel inox blade´s.
Could this affect an MRI of Head, is this a contraindications, ( particles are microscopic/multiple and are interlamellar into cornea )
Thank you for your input
Kind Regards

Hi
My name is Tina and I am currently studying Diffusion weighted MRI. I was wondering if anyone could elaborate on the effect of introducing a slice selection gradient along with the diffusion gradient on the signal attenuation. Also if there are any sites that could explain it, I would appreciate the information.
Thank you.

Hi Oscar,
depending of the indication (tumor, stroke, haemorrhage, epilepsy, inflammation, malformation....) different sequences are useful for brain MRI.
A protocol for a wide range of indications: sagittal T2, coronal Flair, transversal DWI and transversal T1 without and with contrast medium. In case of a result a second plane of a T1 sequence after contrast e.g. coronal is recommended.
