Mri Show Symptomatic Tumor Without Contrast
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
CT Brain shows mass prepontine cistern CPA meningioma. Symptoms consistent with diagnosis. MRI contrast show no lesion. Symptoms persist! Now what?
Very strange: Not certain what to make of the disparity between the CT scan and the MRI. In some cases, a lesion is so small that it is missed by the artifact created by the thickness of the MRI slices. I would ask your doctor if an MRI of the brainstem with "thin slices" might be reasonable to confirm/refute the CT--with and without contrast. Take care and stay healthy! ...Read more
less accurate: While there is controversy about the liberal use of ct scans for the diagnosis of appendicits, it does increase accuracy of diagnosis. There are several parameters on ct scan that are used to diagnose or exclude appendicitis: visualization of the appendix, free fluid around the appendix, blurred fat or fat stranding around the base of the appendix and free air in the area of the appendix. ...Read more
Frequently: MRI if abdomen/ pelvis frequently identify most existing neoplasms but can miss the presence of one, especially if metastatic from a more distant site. We therefore employ PET/CAT to evaluate entire site especially for a hidden primary in the face of metastasis. If multiple liver lesions present, PET can identify which might be hemangiomas and determine approach to be used for management. ...Read more
Either: I usually do them without so I don't expose the patient to the contrast, which can injure kidneys. However, if the tumor is close to the mediastinum, I usually do order it with contrast because it's often difficult to tell the various structures apart without it. It also helps to identify lymph nodes. ...Read more
No: Imaging studies do not show "everything". For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. Get HPV vaccine. ...Read more
Possibly: But not definitively! needs contrast to better define the location and extent. ...Read more
Not likely: Most intracranial vascular anomalies, including aneurysms, require IV contrast to be seen on ct head. However, ct without contrast is 90% sensitive for intracranial bleeding. The risks of IV contrast for ct include kidney injury and allergy to contrast dye. Good luck! ...Read more
Usually: An MRI is probably the best way to detect a brain tumor in a patient who has symptoms or findings on a medical examination that suggests a brain tumor may exist. Getting an MRI if you are asymptomatic(have no medical issues) is unwarranted and should not be done. ...Read moreSee 2 more doctor answers
Usually: Sometimes a spinal cord tumor, especially with extrinsic compression, can result in false localizing clinical signs, which could result in imaging at wrong level, but if precise, the MRI will show lesion. However, you say that you have B-12 issues, and this can cause spinal cord problems in posterior columns, which are also seen on MRI. Do you feel Concierge visit might help? ...Read more
"tumor" literally translates as "mass", so even a fresh bruise could be called a "tumor". Doctors use the term "neoplasm" (tranlates literally as new growth) to describe tumors that are abnormal growths of cells. These may be benign or malignant; "malignant" = cancer. In everyday usage, we use "tumor" ...Read more
