What can a CT scan of abdomen show?

A CT of the abdomen pelves without contrast is often used to evaluate for kidney and ureteral stones. A CT abdomen/pelvis with contrast will show detailed anatomy and numerous potential abnormalities including: normal variations, tumors, bowel obstruction, appendicitis, gallbladder stones and possible inflammation, arterial calcification and arterial stenosis, venous anomalies or thrombosis, bladder stones, bladder abnormalities, prostate size and abnormalities, uterine and ovarian abnormalities, bone and spine abnormalities, etc. A CT abdomen/pelvis is a very fast excellent review of the abdomen and pelvis.
Does an MRI of brains show tumors?

MRI of the brain particularly with and without contrast is the best imaging modality to pick up brain tumors and other abnormalities. Additionally, an MRA sequence will pick up vascular abnormalities such as aneurysms. The MRA sequence adds very little time to the examination length.
Are x-rays dangerous for older people?
No. The small, theoretical risk of cancer induction by X-ray decreases with advancing age.
Can I have an x-ray if I am pregnant?
X-ray of the toes is safe for the baby during pregnancy. They will likely shield your abdomen. The radiation dose is very low for X-ray of the toes and the beam is distant from READ MORE

Can a CT scan detect clogged arteries?
Yes, particularly when it is performed with specific timing and higher contrast flow rates. This called CTA or CT angiography.
Can X-rays show old fractures?
Often old fractures are visible, particularly if there is residual deformity from a fracture that was imperfectly aligned during healing.
What can I expect with an MRI with contrast?
Adding contrast involves an intravenous injection and usually 3 short additional sequences. The total imaging time is usually approximately 30 minutes. Macrocyclic gadolinium agents READ MORE
Adding contrast involves an intravenous injection and usually 3 short additional sequences. The total imaging time is usually approximately 30 minutes. Macrocyclic gadolinium agents such as Gadavist, Prohance and Dotarem have the highest safety profile.
How is a MRI done on the shoulder?

Hi,
You will be put into a magnetic tube. A coil will be placed on your shoulder. You will have to remain very still for the exam which will probably last 20 minutes. Before the exam you will be asked about metal in the body or history of metal in the eyes. You will be asked about implanted devices such as pacemakers, infusion pumps or neurostimulators. You will need to remove all metal, electronic devices, wallet with credit cards, etc., from your person before going in the the room for your MRI. You will be given ear plugs. You will be able to communicate with the technologist during the exam by intercom.
Regards,
Donald Massee

What does a shadow on an ultrasound mean?

This may be a way of communicating an abnormality that needs further work up. Don't be alarmed until you have discussed the findings with your doctor and they may recommend additional tests for clarification. This is not precise terminology that would be used by a radiologist in their report.
How do you stay calm during an MRI?
Meditation, biofeedback and sometimes a benzodiazepine may be required.

Do you have to take your clothes off for an MRI?
Remove wallet, credit cards, keys, jewelry, and watch. Empty all pockets. If you are wearing clothing with no metal, it would be MRI safe. Choose elastic or tie wast band. If READ MORE
Remove wallet, credit cards, keys, jewelry, and watch. Empty all pockets. If you are wearing clothing with no metal, it would be MRI safe. Choose elastic or tie wast band. If the technologist has any questions about your clothing, they may elect to have you disrobe and put on a patient gown.
Is a chest x-ray safe for my baby?
Yes, a CXR is safe for your baby. The average dose for a CXR is .1 mSv which is comparable to 10 days exposure to natural background radiation.
Is it safe to do an MRI scan on my brain?
Very safe and the best imaging modality for most abnormalities of the brain or spine.

Is my son getting too many x-rays?
It is always important to evaluate risk versus benefit with any ionizing radiation. When you say 3 X-rays of the abdomen in a year I am assuming you mean abdominal series. The READ MORE
It is always important to evaluate risk versus benefit with any ionizing radiation. When you say 3 X-rays of the abdomen in a year I am assuming you mean abdominal series. The approximate dose for a 3 view abdominal series is 53 mrem or .53 mSv. Three abdominal series in a year would be 159 mrem or 1.59 mSv. This is 1/2 of the annual natural background radiation we all receive in a year, which is 300 mrem. This would not be considered a harmful dose in this perspective.
Clearly all exams should be performed with caution and dose minimizing techniques. Exams should be indicated. When possible US or MRI can be used in children rather than ionizing radiation. A CT abdomen and pelvis has approximately 1000 mrem or 10 mSv dose. This is 3 times the natural annual background radiation dose. CT in children should be used judiciously and performed with the lowest possible dose that will still provide a diagnostic exam and answer the clinical question.

Breast mammogram vs. breast ultrasound for tumors?

Mammograms are currently the only recognized asymptomatic screening exam. Mammograms are recommended annually beginning at the age of 40 (ACR guidelines). Mammography has been recommended to start up to a decade before a 1st degree relative was diagnosed with breast cancer. US is an excellent supplemental exam for dense breasts. MRI is currently
recommended if there is a +20% lifetime chance of breast cancer. If a 35-year-old patient is symptomatic, then a diagnostic mammography and breast US should be ordered for initial evaluation.

Is it safe for a 10 year old child to have an MRI performed?
MRI does not use radiation and, along with ultrasound, is the best imaging for children. Of course, the indication for imaging must always be factored in.
