How long does an MRI of the abdomen take?
Approximately 30 minutes depends on the number of sequences.
Which is better CT scan or MRI of the abdomen?

Hi,
As a general rule, CT is an excellent imaging modality for the abdomen and pelvis. MRI is especially good for the biliary system and is a fantastic supplemental abdominal and pelvic imaging modality. MRI is more expensive, less available with longer imaging times.

Why does CT contrast make you warm?
The exact mechanism for the heat sensation associated with contrast injection is not known, but it is thought to be related to the difference in the osmolarity of the contrast READ MORE
The exact mechanism for the heat sensation associated with contrast injection is not known, but it is thought to be related to the difference in the osmolarity of the contrast compared to blood. This sensation was worse in the early days of ionic contrast when the osmolarity of IV contrast was 1200 compared to a serum/blood osmolarity of 300. The current nonionic contrast agents have a more neutral osmolarity ranging from 300 to 600. The current nonionic contrast agents also have a much higher safety profile.
Can I wear a bra during a CT scan?
Hi,
A bra with an underwire causes some artifact if the chest is imaged. I therefore recommend a sport bra or no bra during chest CT for optimal artifact free imaging.

Do you get CT scan results soon after?
The results are available to your doctor anywhere from 1 hour to 3 days depending on the radiologist's reading turn around time and the efficiency of report access.
Does a sinus x-ray show infection?
Yes it can. CT is even more accurate.
Why do I need a full body CT scan?
If you are asymptomatic with no significant medical issues, a full body CT scan is not considered necessary. A full body CT scan may be required for follow up of cancer or staging READ MORE
If you are asymptomatic with no significant medical issues, a full body CT scan is not considered necessary. A full body CT scan may be required for follow up of cancer or staging of a new cancer. As a general rule, when evaluating cancer, CT is fantastic for chest, abdomen, and pelvis, particularly with IV contrast. MRI is generally superior for the brain, spine, and musculoskeletal system.
How long does CT contrast stay in your system?
Contrast has a 2-hour half life. This means that at 2 hours, 50% has been eliminated. At 4 hours, 75% has been eliminated. At 6 hours, 87.5% has been eliminated. At 8 hours, 93.75% READ MORE
Contrast has a 2-hour half life. This means that at 2 hours, 50% has been eliminated. At 4 hours, 75% has been eliminated. At 6 hours, 87.5% has been eliminated. At 8 hours, 93.75% has been eliminated. At 10 hours, nearly 97% has been eliminated. At 24 hours, there is virtually no remaining contrast.
Do you get CT scan results immediately?
Typically, the images are interpreted by a radiologist and reported to your doctor. That process may take up to approximately 3 days.
How does a chest x-ray show pneumonia?
Normal lungs are darker because of air in the lungs. Inflammation makes the lungs appear more light or whiter because the infection is associated with purulent debris replacing READ MORE
Normal lungs are darker because of air in the lungs. Inflammation makes the lungs appear more light or whiter because the infection is associated with purulent debris replacing the aerated normal lung.
Can an MRI detect tumors?
Yes, MRI with and without contrast is generally the best imaging modality for brain tumors.

How long does a lung CT scan take?
Actual scan time 1 minute. Total time approximately 10 minutes
Can you be allergic to IV contrast?
Yes. Allergy to contrast can be mild with itching associated with regional hives, moderate with whole body hives, severe with angioedema and bronchospasm associated with acute READ MORE
Yes. Allergy to contrast can be mild with itching associated with regional hives, moderate with whole body hives, severe with angioedema and bronchospasm associated with acute respiratory failure. Allergic reactions to contrast are much more rare with the newer nonionic contrast agents. Rarely, the contrast can cause noncardiogenic pulmonary edema, mechanism poorly understood, but the process damages the basement membrane in the lungs allowing leakage of fluid from the blood filled capillaries in the lung into the alveoli or air sacs in the lung. Side effects of contrast include nausea and vomiting also much more rare with the newer contrast agents. Let the imaging facility and your doctor know in advance if you have had a prior a prior reaction to contrast specifically when and details of the type of contrast reaction. There are ways to pre-medicate if contrast is necessary and there has been a prior contrast reaction.
Can a chest X-ray detect bronchitis?
Bronchitis is usually not detected by CXR. A CXR is generally ordered to detect more advanced infection such as pneumonia that may have clinical signs overlapping with bronchitis. READ MORE

What machines are used to look for cancerous growths?
For the breast mammography and US are the primary imaging modalities. MRI is used for high risk patients. If breast cancer is diagnosed, imaging for metastatic disease may be performed READ MORE
For the breast mammography and US are the primary imaging modalities. MRI is used for high risk patients. If breast cancer is diagnosed, imaging for metastatic disease may be performed with CT or PET CT. Imaging for metastatic disease to the brain or spine is best done with MRI.
How long does a full body CT scan take?
Under 4 minutes varies by scanner speed and patient height.
When is a whole body CT scan needed?
As a general rule, imaging should be confined to the area of symptoms. There are some special circumstances such as evaluation for metastatic disease in a patient with a known READ MORE
As a general rule, imaging should be confined to the area of symptoms. There are some special circumstances such as evaluation for metastatic disease in a patient with a known primary malignancy when CT chest abdomen and pelvis would be performed. Trauma is another indication for imaging of the head, C-spine, chest, abdomen, and pelvis.
What machines are used to look for cancerous growths?
For the breast ultrasound and MRI
