my friend just found out she be pregnant yesterday and she had and MRI scan done a few weeks ago incentive the doctor thinks she might own a boold clot in her brain, tumour, or MS anyway when she go to get it confirmed and the doctor told her that it is his opinion that she terminates the pregnancy, he required her to get the blood experiment done and then discusse the termination. I know that they dont do mri inflict they dont really no what risks it has on the unborn child. Does anyone know anyone who have MRI done whiles pregnant and there child be fine with no defect or any information you can find on this. she had a misscarry a wile ago and she desires to be happy but cant effect she is worried. Feel so sorry for her but happy at alike time. She is a really good friend and I purely wasnt to reasure her that her baby will be ok and she will be a great mum contained by 9 months. Thanks

MANAGING PREGNANT PATIENTS WHO ARE IRRADIATED
Relative agreement exists on when to recommend termination of pregnancy after radiation exposure. The so-called "Danish rule" was offered within 1959 by Hammer-Jacobsen, who suggested termination was advisable for a fetal dose of over 10 rads [1]. This guideline have been widely followed. Wagner et al suggest termination should lone be considered if a radiation dose of over 5 rad occurs between 2 and 15 weeks of gestation, and is probably indicated lone for doses over 15 rad. Hall suggests termination may be considered for a radiation of over 10 rad received between a gestational age of 10 days and 26 weeks [2]. In practice, it is exceptionally unlikely that any single radiological study would deliver a radiation dose sufficient to justify termination. Nonetheless, it is cooperative to be aware of the expected radiation dose from common procedures [3, 4], and the enormity of risk to the fetus per unit dose. This information, which is timetabled below, can be used to counsel pregnant patients who require a study involving ionizing radiation to the pelvis, or who inadvertently undergo such a study at a time when pregnancy is unsuspected.
Procedure
Conceptus radiation dose (rads*)
Abdominal radiograph
0.25
Intravenous pyelogram
0.8
Barium enema
0.8
Lumbar spine radiographs
0.6
CT pelvis
1-10
Note: 1 rad = 1 cGy = 10 mGy = 10,000 uGy
Key point: In practice, it is exceptionally unlikely that any single diagnostic radiological study would deliver a radiation dose sufficient to support termination.

Everytime I guzzle, my stomach blows up so i look similar to im 4 months pregnant. But, im not, what is the problem?
This is a role-play put somebody through the mill for women.?
Why is it that my breasts are sore during some months (before period) and not during other months?
