Radiology/neurology. Ct scan shows bone, MRI shows soft tissue, so therefore can't indentify disease of skull bones. Intercrainial means misdiagnosis?
Yes: Yes.Get a more detailed answer ›
Yes: The bone scan shows areas of active bone deposition as "hot". Osteopenia won't be diagnosed as this denotes loss of bone density. Degenerative disc disease and osteoarthritis may not be demonstrated if they are insufficient to cause a bone response (healing or what is medically called an osteoblastic response). ...Read more
Bone abnormalities: Bone scan involves intravenous injection of radio tracer usually technetium 99m mdp which accumulates in skeleton. Scan may involve early phase(5-10 min) and late phase(2-3 hr) imaging. Increased uptake is seen in fractures, tumors, infection, etc. Decreased activity is seen in metal artifacts, aggressive tumor/infection, & loss of blood supply to bones. Bone scan very sensitive but not specific. ...Read moreSee 2 more doctor answers
No: X-ray will reveal the space between the vertebral bodies where the disc is found but unless the disc is calcified, it will not be visualized as x-ray energy will pass through this soft tissue structure while it does not penetrate the bone but you can get idea of how degenerative the disc may be by seeing how narrowed the disc space is or amount of bone spurs seen around it. Ct & MRI reveal disc. ...Read moreSee 2 more doctor answers
Had 2 chest x rays front/side views.Had 1 CT abdomin, 1 X-ray of neck front/side, 1x ray of my spine for scoliosis front/side, worried radiation exspose?
Read more about it: To learn more about medical imaging and radiation risk, please check out: http://www.Conciergeradiologist.Com/ct-scan-radiation.Html and http://www.Conciergeradiologist.Com/radiation-exposure.Html. Properly indicated imaging studies represent, by definition, situations where the risks of radiation exposure are outweighed by the benefits to the patient. ...Read moreSee 1 more doctor answer
New clubbing fing/toes, episcleritis, headache, parasthesias, joint/chest pain. Chest Xray, chest CT w/contrast, abd CT w/contrast, head ct, cbc, cmp, esr, crp, tsh, pft, ekg, ECG all normal!?!
Yes and no: The X-ray will show a mass on the bony spine , at times haze on the soft tissue on the spine and lesions eroding the spine. Al of these masses that can be seen on X-rays can be benign or malignant. Thus the X-ray will show the mass but can not prove it is cancer without a biopsy ...Read more
Knee mri showed torn meniscus and bone spurs. Now dr wants bone scan.is that scan needed after mri. What would bone scan show that isn't on mri??
No: Plain x-Ray of the neck rules out a fracture, and dislocation, but not spinal injury; CT of the chest does not have the resolution to visualize the spine, only the bone. MRI imaging is better suited to visualize spinal injury. Best to see a neurologist and have a comprehensive neurological examination. ...Read more
Mri shows three lobulations in bone above knee. Bone scan says everything ok. How could mri and bone scan show two different results?
Different studies: The meaning of "lobulations" in the bone on an MRI study is uncertain. This may mean an osteophyte, cortical thickening, old trauma, a normal variant, or something else. The bone scan measures bone chemistry and activity such as repair of the bone. When the bone scan is normal with these findings on MRI, it means normal bone chemistry, and indicates a none serious problem. ...Read moreSee 1 more doctor answer
Not great: X-RAYs are relatively insensitive in the detection of early or small metastatic lesions. Although CT scans are superior, CT scanning is relatively insensitive in showing small lesions, and it has the disadvantage of limited skeletal coverage. Bone scans are very sensitive (they'll pick up everything) but nonspecific (could be just arthritis). MRI and PET scanning are accurate but very expensive. ...Read moreSee 1 more doctor answer
