When is a pelvic MRI needed?

When is a pelvic MRI needed?

Certain situations: Most of the time an ultrasound can visualize the uterus and ovaries as well or better than an mri. Exceptions are if adenomyosis is suspected or if more details are needed on fibroids, especially for pre-operative planning of a myomectomy. An MRI cannot usually distinguish a benign fibroid from a malignant leiomyosarcoma. ...Read more

Mri (Definition)

Mri or magnetic resonance imaging is one of the more recently developed imaging modalities available to physicians. It uses powerful magnets to generate images. There is no ionizing radiation which is a major advantage over many other modalities. Mri is the best imaging exam that we have for most soft tissue and joint related problems. There are radiologists ...Read more

When a brain MRI is necessary?

See long answer: Your dr. Needs to exam you, and place the need for imaging, such as a “brain mri” in appropriate clinical context. There are detailed criteria that are used in making this determination. You can view them on the website for the american college of radiology appropriateness criteria: http://www.Acr.Org/quality-safety/appropriateness-criteria/diagnostic. ...Read more

Does your bladder need to be full to take a pelvic mri? What are the usually finding in a pelvic mri?

Does your bladder need to be full to take a pelvic mri? What are the usually finding in a pelvic mri?

No: Chatty: your bladder does not have to be full for pelvic mri. This test is used to evaluate almost any abnormality in the pelvis. It examines all of your pelvic organs including the uterus, ovaries, bladder and sometimes even bowel problems have been diagnosed. Specifically for women it can help with ovarian tumors, cysts, fibroids, etc. Depending on what your symptoms are. ...Read more

Is it appropriate to have a CT scan for a bone cyst?

Is it appropriate to have a CT scan for a bone cyst?

Sometimes: The issue is usualy being sure it is a bone cyst and not something more sinister- so imaging is one way to help decide this- sometimes a simple xray picture suffices, sometimes a ct or mr scan or bone scan is needed. Sometimes there is enough uncertainty that a biopsy of the area is needed- often with just a needle. ...Read more

When imaging does not reveal a cause for bone pain, what is the next step?

When imaging does not reveal a cause for bone pain, what is the next step?

Not bone pain?: If a bone scan was done using isotope scanning in nuclear medicine, then it is unlikely that the pain is from a bone. Soft tissues around a bone can be a source of pain that may be attributed to the bone. If the bone scan is negative, than it is time to search for a cause outside of the bone in the adjacent joint or soft tissues next to the pain. More importantly, no test is 100% accurate. ...Read more

What is a pet scan, and when would a doctor use it instead of a CT or an mri?

What is a pet scan, and when would a doctor use it instead of a CT or an mri?

PET SCAN: Pet scan is diagnostic test used most of the time to help in the cases of seizures. Pet: positron emission test, depends on the function of the neurons in utilizing glucose, the actve neurons which are active and firing elecrical discharges and causing seizures, pet scan can help to localize the epileptic focus as preparation of epilepsy surgery. ...Read more

Is it possible for a c-spine lesion to show up on a non-contrast t-spine MRI (in the initial focus view), or is it always going to be an artifact?

Is it possible for a c-spine lesion to show up on a non-contrast t-spine MRI (in the initial focus view), or is it always going to be an artifact?

Possible..: The T-spine MRI may show the lower C-spine components which are adjacent to the upper T-spine vertebra, so even though this could be an artifact it is not because of the location but rather because of the technique or the image itself. If it needs definition and confirmation a C-spine MRI should be done. ...Read more

Is it possible for a standard MRI to overlook neural foraminal narrowing but an up-right MRI show it? If pain occurs when upright?

Is it possible for a standard MRI to overlook neural foraminal narrowing but an up-right MRI show it? If pain occurs when upright?

Upright MRI: There are upright MRI scanners. I am not aware of a good study stating upright MRI is better than regular MRI for spinal stenosis. There are anecdotal examples of herniated disc seen only on the upright scan. These scanners are lower resolution than conventional MRI which could cause other findings to be missed. There are only a small number of these scanners in practice in the us. ...Read more

For aAbdominal Myomectomy is it better for a MRI to be done or is just having a ultra sound good enough?

For aAbdominal Myomectomy  is it better for a MRI to be done or is just having a ultra sound good enough?

MRI is the best test: MRI is the best diagnostic test to tell how many fibroids you've and the precise size & position of each fibroid (submucous, intramural, subserous). This is essential info to help your doctor choose the optimal treatment for you in the context of your preferences. Many treatment options exist: watchful waiting; medications; hystero/laparoscopic myomectomy; Uterine fibroid embolization; focused US. ...Read more

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?

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. Factors determining whether contrast is useful (or necessary) include which joint is being imaged, what the suspected injury is and the personal experience/training of the doctors. ...Read more

Is it possible for a pelvic CT scan to not detect a tumor in the rectum? How likely is that?

Diagnosing rectal ca: Some symptoms may be due to benign conditions and are not necessarily cancer. Pelvic ct scans are routinely used to detect rectal cancers, but small cancers may escape detection. A qualified physician should perform a physical exam and order additional tests, usually a combination of scans, blood tests (including tumor markers), plus colonoscopy. ...Read more

Is there a shot or an i.V. Involved when doing a lumbar CT scan with dye?

Is there a shot or an i.V. Involved when doing a lumbar CT scan with dye?

CT with contrast: Before the study, an IV will be started, through which the contrast ("dye") is injected. Usually a lumbar scan is done first without contrast and then a second time with contrast to enhance structures like discs, spinal cord, nerves. They may request a blood test of your kidney function to make certain your kidneys can deal with the contrast. ...Read more

Can a ligament tear be noticed in an x-ray, or is an MRI scan necessary?

MRI much much better: Radiographs can sometimes show subtle abnormalities, or the presence of a chronic care which is calcified. However, MRI is outstanding in imaging soft tissue including the tendons and ligaments and is by far the preferred method for imaging soft tissue injuries and joints. ...Read more
