I had a CT scan 10 years ago due to headaches. It came back abnormal. It said a focal, well circumscribed area of low density is identified within the region of corpus. I did an MRI after that and the results were normal. Should I be worried?

MRI more sensitive.: The results of a brain MRI are more conclusive than the results of a CT scan, so if the MRI reading was correct, then you would have little to worry about.

However, if you happen to have copies of the studies on a CD, you can request a secondary review by initiating a private consult here on HealthTap. ...Read more

Computed Tomography (Definition)

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

You have a: Postural headache. Your workup is nearly complete, but has a lumbar puncture (aka spinal tap) been done yet? Without fever, altered mental status or meningeal stiffness it is not likely to be meningitis. If you have postural headache, that probably means you are dehydrated or volume low. Take in 3-4 L of fluid daily. ...Read more

Is insomnia related to brain or need to do MRI CT scan if all body result is normal?

Is insomnia related to brain or need to do MRI CT scan if all body result is normal?

Insomnia: Insomnia is related to the brain, but MRI scan will not delineate "why" you can't sleep. I suggest consulting with a psychiatrist and/or sleep medicine physician, insomnia can result from primary sleep disorders like sleep apnea, and also from psychiatric conditions like depression and anxiety disorders. Effective reatment is possible only with a thorough evaluation first. Best wishes. ...Read more

I get dizzy every day since I gave birth 4 months ago. I had a CT scan, MRI, EEG, blood work done with normal results. What could it be?

I get dizzy every day since I gave birth 4 months ago. I had a CT scan, MRI, EEG, blood work done with normal results. What could it be?

Suggestions: Your testing appears to rule out central causes of dizziness in brain, and systemic causes due to anemias, or bodily disorders, BUT does NOT exclude inner ear pathology, which should be evaluated. See an otolaryngologist and get appropriate testing, as inner ear pathology can be treated with vestibular rehabilitation by a skilled physical therapist. ...Read more

What if patient evaluated by pt dr. Shows all symptoms of sciatica but CT scan & MRI shows normal?

Spine Pain Options: This pain in the distribution as you suggested is the result of an irritated nerve or facet joints or other injury typically in the lumbar spine (low back) which are caused by herniated disks, spinal stenosis or degenerative disc disease, etc requiring further evaluation by a spine specialist and may be candidate for facet injections/radiofrequency ablation and epidural steroid injection. ...Read more

I have pain in my head from last 3 years. 1month ago my CT scan and MRI of head are normal..

Be reassured: At your age, if imaging studies (especially mri) are normal, your most likely have a benign origin. Consider stress, migraines, or even sinus congestion as possible causes which can be corrected. However, if the headaches are sometimes severe, consider consulting with a neurologist specializing in headaches. ...Read more

I have been getting headaches and migraines since I was six. I got a CT scan and its normal. Is there anything an MRI might show that the CT didnt?

I have been getting headaches and migraines since I was six. I got a CT scan and its normal. Is there anything an MRI might show that the CT didnt?

Yes: MRI is much more sensative to the tissue of the brain. This doesn't mean it will, but you should consider it. The MRI also gets a better look at regions of the brain that CT has trouble with due to the bones of the skull. Children usually do not get headaches so as you get older any finding may be more readily seen. Talk to your doctors ...Read more

See a neurologist: Your symptoms could be part of an headache syndrome. Things to consider are: pseudo tumor cerebri, sleep apnea, tension headache, migraines, neck problems... A neurologist can sort this out. ...Read more

CT scan shows nonspecific mild nodularity/thickening of medial left adrenal gland. Having MRI this week. Is this why I have pain there? All else normal

CT scan shows nonspecific mild nodularity/thickening of medial left adrenal gland. Having MRI this week. Is this why I have pain there? All else normal

Unlikly cause o pain: It is very unlikely that you are experiencing pain from your adrenal gland. The adrenal gland sits at the top of the kidney and produced hormones. You can get bleeding into the gland which can be felt as pain, but that situation does not appear like nodular thickening. The follow-up MRI is used to exclude a mass as the cause of the thickening. ...Read more

At age 33, I had to have a CT scan followed by MRI. The results-had Cerebral Atrophy. Is this a concern for me and should I worry?

At age 33, I had to have a CT scan followed by MRI. The results-had Cerebral Atrophy. Is this a concern for me and should I worry?

Neurologist: I recommend an evaluation by a neurologist as cerebral atrophy is premature in your age group. If your cognitive and neurological examinations are perfectly normal the ct scan findings may be questionable or insignificant. ...Read more

Ct scan said right lipid laden adrenal adenoma 1cm. Mri did not see any adrenal adenoma. Is this normal? Dr. Said to go with mri. Should I 2nd opinion

Adrenal lesion: If the ct is definitive for fat density and it is clearly an adenoma, further imaging is usually not indicated. I cannot make a diagnosis without the images. It may be that the lesion was not well seen on MRI given the small size. Mri is also incredibly sensitive to movement/breathing. An adenoma is benign, and would require no further imaging anyway. So there should be no cause for concern. ...Read more

After two year evaluation lung nod with CT scan normal can I have MRI once year after that to monitor my condition?

After two year evaluation lung nod with CT scan normal can I have MRI once year after that to monitor my condition?

Depends: It depends...If you want to follow the stability of a lung nodule, it's best to continue with the same modality (accurate comparison) and if the nodule is small, it may be too small to see with a chest mri. There may also be an advantage for a chest ct over an MRI depending on the reason it is being ordered such as cancer screening. I would talk it over with your doctor and radiologist. ...Read more

I had a CT scan showing cortical and cerebellar atrophy with prominent sulci. A few months later, I had a CT & MRI and it came back normal. Thoughts?

I had a CT scan showing cortical and cerebellar atrophy with prominent sulci. A few months later, I had a CT & MRI and it came back normal. Thoughts?

Your age says 28, so: I doubt that you have brain atrophy. The radiologist for your first exam may have a low threshold for calling brain "atrophy" since it's so common in the elderly, but your age would need to be taken into account when making a report like that. Since the second report came back "normal", I would tend to agree with that one. If you have other concerns consider an HT Concierge visit. ...Read more

Why do doctors ask to do MRI and CT scan and all I get is all normal. But it say nonspecific hypoattenuation within white matter t2 flair hyperintensi?

Why do doctors ask to do MRI and CT scan and all I get is all normal. But it say nonspecific hypoattenuation within white matter t2 flair hyperintensi?

Artifact.: What it does show is a nonspecific finding that the radiologist cannot define exactly what the character is. Also it does not show any signs specific for a disease process, tumor, cancer or other lesion. At best your primary care doctor maybe reorder another study in three months to one year later to see if there is any change if the reason you had in the first place persists. ...Read more

What's better for diagnosing pancreatic cancer.... Ct scan or mri? I've had normal ultrasound and CT scan with contrast. Still worried.

Why worried?: Why are you worried? Do you have symptoms or abnormal labs?

If the ct was normal and used a specific pancreas protocol, then an MRI of the pan creas may be the best next test. Since it does not use radiation, there is little risk for you. ...Read more

What's better for diagnosing pancreatic cancer? Ct scan or mri? 34yr male. I've had normal ultrasound and CT scan with contrast. Still worried.

CT, ERCP, MRCP: Thin-slice (3 mm) ct abdomen yields fine detail of pancreatic structures... Blood tests including tumor markers: ca-19-9, ca-15-3, and CEA can alert the clinician for ca. Also, ERCP w/ ductal brushings (though its endoscopy) can search for malignancy. Finally, mrcp may add to the clinical picture, but 64-bit ct is slowly encroaching on the former's superiority. ...Read more

Offbalance when looking down and standing still. Mri/ct scan, ENT, cardio., bloodwork all normal. What else can I be tested for? Neck a little tight

ENG- nystagmogram.: It sounds like the problems occur only when your gaze is in a specific direction (looking downwards). Usually, these problems are NOT diagnosed by imaging tests, as the problem is FUNCTIONAL (with nerves) - there's nothing wrong with the way your body has formed. The best test of nerve function is an electronystagmogram - they measure your balance nerves & give you a diagnosis. You need a diagnosi ...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
