X-ray can diagnose AVN of the hip when it is more advanced. MRI is considered the most accurate and most sensitive. If the degenerative joint disease of the hip is secondary to AVN of the hip this is considered to be the most advanced stage and generally requires a surgical hip replacement.
When should you get an MRI for a headache?
Your doctor will consider ordering an MRI of the brain for persistent or recurrent headaches, change in headache type/location, or a new headache. A headache with a neurological READ MORE
Your doctor will consider ordering an MRI of the brain for persistent or recurrent headaches, change in headache type/location, or a new headache. A headache with a neurological deficit will definitely require an MRI. A headache with a history of cancer would be a good indication for MRI. In general, your doctor will evaluate your headache history, examine you, and determine if an MRI brain should be ordered. If cancer or infection are considered, MRI brain with and without contrast would be ordered.
How many x-rays are safe for a child?
Each procedure with radiation is always performed with the expectation that the exam is appropriate and performed with attention to minimizing radiation dose. We don't have absolute READ MORE
Each procedure with radiation is always performed with the expectation that the exam is appropriate and performed with attention to minimizing radiation dose. We don't have absolute number cut offs. Image gently at all times.
How much radiation do you get from fluoroscopy?
It depends on the fluoroscopy time mostly. It also depends on a setting of pulsed versus continuous. Finally it also depends on the thickness of the body part being evaluated. READ MORE
It depends on the fluoroscopy time mostly. It also depends on a setting of pulsed versus continuous. Finally it also depends on the thickness of the body part being evaluated. Most states now require some information in the report. As a general rule 1 minute of fluoroscopy is associated with 5-10 mGy of radiation.
MRCP Contrast Dye?
I would have to evaluate the post contrast sequences to determine how much contrast did make it into your vascular system. The radiologist will likely comment on this in his report. READ MORE
I would have to evaluate the post contrast sequences to determine how much contrast did make it into your vascular system. The radiologist will likely comment on this in his report. It sounds like you had a loose connection in the tubing or IV heplock hub. You may have had some but not all of the contrast leak out. Alternatively, the flush may have leaked out and the
contrast was all successfully injected.
contrast was all successfully injected.
How long does a fluoroscopy procedure take?
It depends on the fluoroscopy procedure, but generally, an UGI takes less than 5 minutes and a barium enema takes less than 15 to 20 minutes.
Can you drink water before a fluoroscopy?
It depends on the fluoroscopy exam. For an UGI, generally nothing should taken by mouth for 8 hours prior to the exam. The barium coats the stomach mucosa better and the exam is READ MORE
It depends on the fluoroscopy exam. For an UGI, generally nothing should taken by mouth for 8 hours prior to the exam. The barium coats the stomach mucosa better and the exam is more diagnostic if the stomach is empty at the start of the exam.
Will my pregnancy be affected by this?
This should be discussed with your doctor. Both of these procedures involve radiation to the abdomen and pelvis. We try to avoid radiation throughout pregnancy, but particularly READ MORE
This should be discussed with your doctor. Both of these procedures involve radiation to the abdomen and pelvis. We try to avoid radiation throughout pregnancy, but particularly the first 8 weeks of pregnancy. The most likely outcome is still a healthy baby. Please discuss with your Ob/Gyn physician. The CT dose was likely around 5 mSv and the fluoroscopy study was likely a similar dose. Those studies will likely record the exact dose you received. This will likely be recorded in the radiologist report.
Can CT scans cause thyroid problems?
No. However, since IV contrast has iodine which is taken up by the thyroid, it is best to wait 6 weeks before an I123 or I131 nuclear medicine exam.
What is the difference between fluoroscopy and radiography?
Radiography is taking preset images of a body part. Fluoroscopy involves real time live imaging, often by a radiologist during a procedure.
Localized pressure-like headache for 4 months?
I would recommend a neurologist. There are many different headache types and different medications for relief. I would recommend MRI brain without and with contrast with MRA. If READ MORE
I would recommend a neurologist. There are many different headache types and different medications for relief. I would recommend MRI brain without and with contrast with MRA. If this imaging workup is normal, brain tumor would be exceedingly unlikely.
Is covid-19 dangerous to a child who recently had radiation?
Radiation therapy, particularly if it involves a significant portion of the skeleton, and therefore bone marrow can lower the immune system activity and make people of any age READ MORE
Radiation therapy, particularly if it involves a significant portion of the skeleton, and therefore bone marrow can lower the immune system activity and make people of any age more susceptible to infections of any kind. This would be a good question for the treating radiation oncologist and your physician since there are several follow up questions I have regarding
your child's particular case. They would immediately know the answers.

What happens if you eat before a CT scan with contrast?
Occasionally, the contrast may cause nausea and vomiting, much more rare with modern contrast agents. If the stomach is the area of primary concern it is nice to have the stomach READ MORE
Occasionally, the contrast may cause nausea and vomiting, much more rare with modern contrast agents. If the stomach is the area of primary concern it is nice to have the stomach clear of food so the gastric mucosa can be carefully evaluated.
Can an x-ray show brain swelling?
CT of the head can show brain swelling, and an MRI of the brain is even better for brain swelling and a large range of brain abnormalities.
Does an x-ray show muscle damage?
The best study for muscle injury is MRI. X-ray does not show good muscle detail.
Does bronchitis show up on the CT scan?
Not usually, however, there are some findings that may be seen such as endobronchial mucous. Bronchiolitis may be seen as a tree in bud pattern, but this is a different entity. READ MORE
Not usually, however, there are some findings that may be seen such as endobronchial mucous. Bronchiolitis may be seen as a tree in bud pattern, but this is a different entity. There are findings on CT that may predispose to recurring bronchitis such as bronchiectasis. CT most often would help differentiate a clinical diagnosis of bronchitis from something more serious requiring different treatment such as pneumonia.
Medical exam side effects?
Those symptoms are not related to your mammogram and ultrasound. They are unrelated. If the symptoms persist or worsen, please contact your primary care doctor.
Can you get an MRI or CT scan while pregnant?
Imaging in pregnancy is always determined by the necessity for the mother's health. As a general rule, any necessary imaging can be performed. If possible ultrasound is used. MRI READ MORE
Imaging in pregnancy is always determined by the necessity for the mother's health. As a general rule, any necessary imaging can be performed. If possible ultrasound is used. MRI is the next favored modality during pregnancy. CT is considered generally the least favored during pregnancy, especially when the imaging includes the abdomen or pelvis.
