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

How long does it take for a brain aneurysm to develop?

How long does it take for a brain aneurysm to develop?

Unknown: There is no good answer to this question because we have only limited data on exactly how, when and why brain aneurysms develop. Once an aneurysm is identified, if it is non-ruptured and small (<5mm in size), we often follow these with yearly tests to see if the aneurysm is enlarging. In these cases, they tend to grow at varying rates or not grow in size at all. ...Read more

How long does it take to recover from a brain biopsy? (assuming it is negative)

How long does it take to recover from a brain biopsy? (assuming it is negative)

Short time: A stereotactic biopsy does not take much time to recover from at all (hours to a couple of days). Headache is the most common side effect. Open brain biopsy done via a "burr hole" would take slightly longer -- but both are very standardized and neurosurgeons are the specialists with the longest number of years of training: 9 years after medical school. They know what they are doing. ...Read more

How long does it take for a contrast head CT to cause brain cancer?

How long does it take for a contrast head CT to cause brain cancer?

It shouldn't: Contrast enhanced ct scans are not a risk for brain cancer. In fact more tumors have been cured by finding them early with ct scans and mris than have ever been caused. There was a scare with ct angiograms at one time because a few machines gave large doses of radiation. For the most part, this is no longer the case. ...Read more

Contusions that are clinically important generally have laboratory and EKG signs of injury. The damage is no longer ongoing when lab values cease to keep trending up. The rate at which it takes to return to normal is not entirely clear. Note: this is not the same a fractured sternum.. ...Read more
