Jaw Bones And White Areas On Ct Scans
Shadow on CT scan mastoid bone area, MRI results clear, had ear infection and still do. Would MRI only show intercrainial and not bone disease?
Probably: Mri and ct are complementary studies so there is always the possibility that one study will show an abnormality that the other doesn't. Typically a 'shadow' in the mastoid bone means fluid and that should show up on mri. But not knowing for sure what is meant by 'shadow' in your case, i can't be 100% about that. Ask your doctor about your case specifically or an ENT specialist or a neurologist. ...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
Will skull x rays spot any fracrures, hairline fractures or other damage on the forehead and head?
Depends on size: A complete skull X-ray set (which includes the "Water's view" of the sinuses) are relatively good at spotting big fractures, which are displaced or depressed (i.e., discontinuous). A hairline fracture could be missed on X-ray but picked up on a CT scan. Small hairline fractures can even be missed on CT scan. Best to work from symptoms: if you have pain after an accident, see a doctor to diagnose. ...Read more

CT: CT (Computed tomography) can examine any anatomical part of the body. It does use ionizing radiation to acquire imaging so typically only the necessary part of the body in question is imaged. So a CT chest would be performed separately from a CT of the brain. Indications would depend on your symptoms and what your doc is looking for. Always discuss your concerns with your doc and radiologist. ...Read more
My dad had a nuclear bone scan. Nuclear bone scan findings:
there are several focal areas of isotope accumulation in the region of the
sacroiliac joints bilaterally which correspond to lesions noted on the CT pelvis consistent with bony me
Possibly metastases: Nuclear bone scans usually demonstrate areas of increased bone metabolism, the bone reacting to a stimulus, such as tumor, fracture, infection, etc.Bone scan is very sensitive but not specific. Ct and MRI are cross sectional imaging that can more specifically identify the pathology and characterize the abnormalities on bone scan. ...Read moreSee 1 more doctor answer
Maybe not: Areas if increased uptake can be caused by a number of different things. Fractures can do this as well as arthritis (if near a joint), infection and yes cancer can do this also...But other bone lesions that are not considered malignant can also do this. This is why it is so important to see your doctor, who can put this information together with your history, symptoms and results from other tests. ...Read moreSee 3 more doctor answers
Yes and no: Areas with cancer are usually hypermetabolic in a pet scan due to the increased uptake of the radioactive glucose by cancerous cells. Looking at an FDG pet scan alone, you can grossly see "dark" areas in the brain, heart, kidneys and bladder and these are due to physiologic distribution/excretion of fdg. Not all "dark" is cancer and cancer is often but not always "dark". ...Read moreSee 3 more doctor answers

Radiology/neurology. Ct scan shows bone, MRI shows soft tissue, so therefore can't indentify disease of skull bones. Intercrainial means misdiagnosis?
Would anything show on MRI that wouldn't show on xray or ct scan with no dye.Swollen painful luq for 4 months. On and below ribs. Clear ct and xray.
LUQ pain: There are many things that can cause left upper quadrant pain. If an x-ray and a CT scan have been negative, it is doubtful that the next test would be an MRI. It would be more likely that an endoscopy or some other way to visualize the upper digestive tract would be more appropriate. Talk to your doctor about the next step if your symptoms continue. Good luck. ...Read more
Bone is a living growing tissue made mostly of collagen (protein that provides soft framework) & the mineral calcium phosphate that adds strength & hardens the framework. Two types of bone are found in the body; cortical (dense compact outer layer) & trabecular (makes up inner layer, ...Read more
