| GE 8 channel Body Coil Artifact |
Have a GE 1.5T HDxt. Problem: experiencing symmetric artifacts in abdominal images. Artifact seen in most anterior images: Some are rectangular in appearance, another reminds me of a plastic knife. All patients are changed in gowns/pants prior to entry into MRI suite. The body coil in question has been changed 3 times but the artifact remains. I suspect this is a hardware reconstruction issue, however, the engineer thinks it is operator error. I have run this sequence with and without options. This is an SSFSE, breath hold sequence. Has anyone encountered this issue?

Hi! Working as an MRI Technologist requires a lot of talking to the patient. You must screen the patients yourself, talk to them in between pulse sequences to ensure they are doing alright, and during breath hold exams. There is a huge safety factor with MRI with keeping certain metals away from the magnet so screening each and every person is a huge factor with being a MRI Technologist. As a MRI Technologist for a mobile company i speak with a radiologist that works at another facility for protocols and questions regarding exams and ensuring we get everything the patient and ordering doctor needs. If you have a MRI school in your area i would email or call them to see if any accomodations could be made, but i know from working mobile and at surrounding hospitals in this state and nearby states i live in, you would need to speak to the patient.

For a better result of MRCP, a patient should be NPO for abt 6 hours.Then just five minutes before starting the scan,pure pineapple juice(500ml)is given.Magnesium found in pineapple, acts as oral contrast in biliary tract thus gives a sharp and bright clear image.For the sequence breath hold should proper.

Hello to all my fellow MR Technologists and / or students:
I have a few questions that I would greatly appreciate if someone could help me answer. The dead line is THIS Friday 25th 1000AM morning so please reply STAT
Please e mail me at USMARINE2TIM2@YAHOO.COM
1. . Breath hold duration of less than _________are
recommended when dealing with MR Arenal artery
scan?
a. 30sec
b. 25sec
c. 18sec
d. 8
2. . In renal angiography, what anatomical
landmark does the 3d slab need to cover just
anterior to?
a. Adrenal glands
b. Hepatic vein
c. Portal vein
d. Abdominal aorta
3. .What makes MRI a better choice than DSA for evaluation of a bilateral renal artery stenoses at the orgins of the renal arteries?
a. It is a noisier examination
b. The contrast used is less nephrotoxic than DSA
contrast
c. MRI has higher special resolution than DSA
4. Signal loss will result when further maturation of the clot produces which one of the following?
a. methemoglobin
b. hemosiderin
c. phagocytosis.
d. hemoglobin
5. .For cine gradient echo imaging with true FISP, which of the following statements is TRUE?
a. .images have better image contrast and acquisitions are faster than conventional cine gradient echo imaging
b. cine true FISP images can be performed on any MRI unit
c. to make true FISD images, intravenous gadolinium contrast is needed
d. .true FISP images cannot be used for breath- hold acquisitions because the sequence is too slow
6. Which one of the following statements is NOT
true about phase contrast imaging?
a. .phase contrast imaging is useful for measuring blood flow
b. .phase contrast images are ECG gated
c. .phase contrast images can be performed on most
scanners with cardiac imaging capabilities
d. phase contrast images required
intravenous gadolinium contrast
Thank you so much

| CE MRA of the Liver |
Which injection rate and amount of Gadolinium works best for CE MRA of the liver with a good portal venous contrast? We have a power injector and a 1.5 T system. With a flow rate of 3 ml/sec and 20 ml contrast agent the arterial contrast but the portal phase could be better. Our MRA's are done with 15 sec. scan time for one breath hold.
