When Do They Need A Ct Or Mri To Detect Ivh
For a term, rarely: If a term or a late preterm infant is stable enough to be transported to ct or MRI area, and less than 4 days old, ct is preferred. Otherwise MRI is the best. They are recommended if the infant has seizures, extreme lethargy or irritability, recurrent apnea (forget to breath), evidence of trauma (like head injury from forceps or vacuum delivery), suspected shaken baby syndrome, CNS infections etc. ...Read moreSee 1 more doctor answer
Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more
Does a CT show how much plaque is present in the carotid siphons? Or do I need to do further tests
When the ER doc is doing a CT scan on head to check for tumor and or aneurysm , do they have to use contrast? Or can I get it without contrast?
For the best study: For brain tumors, a ct scan of the head without and with contrast best delineates the tumor. To check for an aneurysm, contrast is needed for the ct-angiogram. If you are concerned about radiation and contrast, and if it is an elective evaluation for brain tumor or aneurysm, you might consider an mri/mra. ...Read moreSee 3 more doctor answers
Can spine X-ray diagnose small fractures? Or do you need to get CT or MRI anyway and skip x-ray? .
Can a CT scan be done without constrast to show coronary arterys just to see if they are congenital anomolies?
No: A contrast enhanced exam is necessary to assess the coronary arteries in a meaningful way in young patients, especially. Cardiologists use contrast for catheterization, but noninvasive coronary angiography with contrast is preferable.

How often do you need to use PET scan or bronchoscope to locate lung cancer because it does not show on CT scan but symptoms tell you to keep looking?
Clinical judgement: This pathologist is underwhelmed with the health or public benefits of intensive screening for tiny lung cancers. I'd hope that if the person is symptomatic, some other investigations are undertaken and the actual cause gets found. ...Read more
What tests can be done that would be able to detect if I have a arteriovenous malformation or not? Mri? Ct? Other?
Would a brain MRI with and without contrast show problems with sinuses(cyst or tumors)or do they have to order MRI specifically for the sinuses?
How will a neurologist know if you had a TIA or not? What are the key things that stand out as a tia? Do they show up on a CT scan or an mri?
History: Tia symptoms are short lived, minutes to hours and should completely resolve in 24 hours. At your age ct and MRI are done to exclude tumor or bleeding. Other conditions that could be present would include migraine which usually has a more gradual presentation than tia. ...Read moreSee 1 more doctor answer
Can MRI detect tumors(benign/malignant)? The MRI only shws a lesion but do not knw if its benign. Is it necessary to do a PET scan to find out more?
Yes: The MRI is an effective way of defining a tumor. The histologic diagnosis is suspected mostly by presence and possible involvement of adjacent tissue. When there is a question of trying to define the presence of a primary in the face of metastastic disease, the PET/CAT most often defines the presence of a Ca. ...Read more
Can a full body MRI or CT scan identify all tumors so that biposies can be done before they have a chance to become malignant?
Not really : Some tumors are seen better on CT scan others on MRI, different techniques, radiation dose variation etc are needed for different parts of body and very small tumors can not be seen even on these tests. For total radiation exposure, cost etc , at least at present total body imaging is not the best screening method however it is used to find metastatic lesions in known cancer patients using PET etc ...Read moreSee 2 more doctor answers
How do you diagnose mythensia gravis, a blood test can't do it?What are the definitive tests when MRI scans are refused to be studied properly by neuros
Multiple modes: Often multiple tests are used and needed to diagnose myasthenia gravis. If you are not satisfied with one doctor you may seek a second opinion, however, it multiple doctors provide the same or similar advice, you will need to look inside yourself.

Mri without contrast detect hemanginoma at t 2 ? Could they tell if it is a hemanginoma and not cancer?
Depends on: Anatomical location of investigation, and the type of tumor. Sometimes you need both. And these scans tell you about anatomical abnormalities, nothing about function. ...Read more
Does a standard brain CT or MRI go down far enough to be able to see a chiari malformation if there was one?
Do CT scan/mri's when they check for tinnitus require contrast? Will they check all the vessels in my brain? Or is it just normal mri?
I have a f/u chest+abdomen+pelvis CT w/contrast scheduled in 3mos. Will that routinely pick up abnormalities in breast & axillary lns if any? Do i need to tell radiologist about unilateral tender lns?
It depends: What your doctor is looking for. Most head ct scans are done without dye. ...Read more
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
