A CT scan usually takes about a half-hour from start to finish. Most of the time is used for prep, but the actual time for the scan itself is short, usually less than 30 minutes. Sometimes it may take longer if you have to drink contrast material and wait for it to take effect. T...
Both MRIs and CT scans are used to create pictures of your organs to help doctors discover and diagnose potentials issues. The main difference between these two sophisticated imaging techniques is that CT (computed tomography) scans use X-rays while MRIs (magnetic resonance imaging) use radio wave...
The researchers emphasize that when a child suffers a major head injury or develops a life-threatening illness, the benefits of clinically appropriate CT scans should outweigh future cancer risks. The results of the study were published online in The Lancet on June 7, 2012.Nurse practitioner ...
Current approaches, involving patients and families, professional and regulatory bodies are helping to achieve a better balance between the risks and benefits of CT scanning as they are currently understood. Over time, new research evidence will support improved guidelines that can better optimise the ...

In conclusion, everything we encounter in life carries risks.Although the radiation received from PET/CT studies is not trivial, the benefits of PET/CT for cancer diagnosis, confirming the need for surgery, and monitoring the progress of ch...
Benefits & Risks Your physician and our radiologists only recommend a PET when it is essential. The information the scan provides is unique and often unattainable using any other imaging procedure. For many diseases, a PET yields the most useful information for correct diagnosis and for best deter...
