A positive fast result is defined as the appearance of a dark (anechoic) strip in the dependent areas of the peritoneum. In the right upper quadrant this typically appears in morison's pouch(between the liverand kidney). This location is most useful as it is the place where fluid will collect with a supine patient.

Magnetic resonance imaging (mri) mri produces very clear pictures of the human body without the use of x-rays. Mri uses a large magnet, radio waves, and a computer to produce these images.
T2-weighted imaging is performed with a longer tr and te (ie, tr 1800 msec, and at least one echo with a te ≥60 msec) when compared with t1w sequences. 9,10 t2 images are achieved either by conventional se, fast se, or gre imaging. Images obtained with conventional se pulse sequences take longer and are prone to motion artifacts.

Fast spin echo t2 weighted breast mri in addition to the dynamic mri sequences, a ‘ fast spin-echo ‘ t2 weighted sequence also frequently performed in contrast enhanced breast mri’s in order to assess cystic changes or edema which may be present. Most benign breast lesions will show brightly on t2 weighted images.
A prostate mri is non-invasive imaging alternative that your doctor might recommend if your psa levels are elevated. Often, it is the next step after a psa test and a digital rectal exam, and before a more invasive prostate biopsy. An mri machine uses magnetic and radio waves to produce detailed images.

A 10-minute breast mri exam called fast breast mri found more cancers than 3d mammograms in women with dense breasts, according to a study.
I had my first-ever mri, and i’ll admit i was a tad nervous. Note: the entire mri scanner is magnetized such that it’s strong enough to send things like hospital gurneys, floor buffer machines, and office equipment flying across the room in the process of being sucked into the machine itself!.
At first look mri, no order is required and the results are sent directly to you, the paying customer, and to the doctor you specify.
