When Is A Sonohysterography Useful
Identify problems.: If the lining of the uterus looks thickened on ultrasound, the cells may be growing excessively or a fibroid or polyp may be within the cavity but not well seen because the cavity walls are collapsed around it.

When a doctor requests an MRI what is the criteria for requesting this test with or without contrast? If a tear is suspected, is contrast best?
It depends: Contrast injected in a joint can increase the likelihood of identifying a subtle abnormality (e.g., labrum injury, post-op knee) on mri. In many cases, a ligament injury will be visible without the contrast.

If the patient stops breathing and no pulse is detected, and no AED device is readily available, then CPR needs to be instituted. ...Read moreSee 2 more doctor answers

Virginity: Nope. There is no real and valid test for virginity. The old fashioned examination of the hymen is just outdated to most of the world. We also have no test for virginity for men and i would bet that every doctor here on health tap would agree that if virginity is important it has to be equally important for the man as it is for the female to be a 'virgin'. Inequality in the sexes has to end. ...Read more
