What are the best sequences for evaluating of the female pelvis. Regarding that I am doing a research on the role of DWI in characterization of female pelvic masses. Our machine is a Hitachi Airis Avento. I did not find the b value, however a diffusion button is there. rn

| Hyperintense blood vessels in SE |
Prolonged T1 relaxation times, decreased T1 tissue contrast, and increased susceptibility rnare typical effects at high field MRI.rnDue to the longer T1 times at 3T, the signal rnintensity inside the vessels is preserved even in smaller vessels. Try TR 700, TE 10.rnInversion recovery sequences are very well suited for optimal gray to white matter contrast, but enhancement after administration of gadolinium may not be visible.

I have a quick question about a pulse sequence. What is the difference between a conventional SEMS vs STEMS?

| Dixon technique |
I have been searching the web for information regarding a "double-echo two-excitation pulse sequence encoding fat and water signals for a phase-sensitive three-point Dixon type analysis". Does anyone know what pulse sequence(s) this is referring to, or a publication that might be helpful???
Thanks

| Best pulse sequences for spinal cord demyelination? |
Small spinal cord lesions, even if clinically significant, can be due to the low sensitivity of some pulse sequences. Demyelinating lesions are better seen on STIR-FSE images, on which the number of lesions are significantly higher than on FSE, while the FSE and CSE images show approximately equal numbers of lesions.So as STIR-FSE has high sensitivity to demyelinating lesions,it can be considered quite specific and should be included in spinal MRI for assessment of suspected demyelinating disease.
